"Gas Sweetening Technologies"
DDR-type Zeolite Membrane: A practical solution for CO2 separation in the oil and gas industry
Speaker: Hiroaki Hasegawa, JGC Corporation
JGC Corporation (JGC) and NGK Insulators, Ltd. (NGK) are jointly developing the DDR-type zeolite membrane system for CO2 recovery from associated gas and natural gas. This nano porous zeolite membrane prepared on an alumina substrate has advantages such as high CO2/CH4 selectivity compared to conventional membranes, high durability and no restriction on the partial pressure of CO2 for operation. The DDR-type zeolite membrane system can therefore be applied at high pressure and with high CO2 concentration in gas production where conventional polymeric membranes can be significantly plasticized and lose their performance.
JGC and NGK have already completed the laboratory testing of the DDR-type zeolite membrane to confirm resilience and performance at high pressure and high CO2 concentration and assess the effect of impurity components. The DDR-type zeolite membrane system is now at the demonstration test stage where JGC has prepared and operated a DDR-type zeolite membrane system which can treat 3 MMSCFD of associated gas. The aim of the test is to evaluate the superior performance and the long-term durability of the membrane system using actual gas in a real CO2-EOR field. In this paper, up-to-date information for the membrane and progress on the demonstration test will be introduced.
Membrane requirements for efficient natural gas sweetening

Natural gas (NG) has become an increasingly important resource for power production and as feedstock for the chemical industry. But as the worldwide availability of CO2 lean NG decreases, unconventional NG sources with high CO2 concentrations and considerable contents of heavy hydrocarbons (HHC) must be used. Removing CO2 from NG with membranes is a proven technology but, in many cases, conventional membranes lack stability against plasticization and degradation at high CO2 and HHC partial pressures, which increases the frequency of membrane exchanges and reduces the methane recovery.
To treat such gases more efficiently, a highly selective and under NG process conditions stable membrane is essential. Such a membrane has been developed in close cooperation between Evonik and Linde. Extensive laboratory experiments and field data showed an excellent separation performance, HHC resistance and plasticization stability. In various commercial applications, a selectivity of approximately twice the value of conventional membranes has been proven. CO2 could be removed with considerably less hydrocarbon losses and reduced energy requirements. Additionally, the extended long-term stability of this membrane allows an extended replacement cycle and thus reduces downtime and associated costs.

Young Professional Session: "Carbon Capture, Utilisation and Storage"
Global Warming and Climate Change: Hoax or reality?
Speaker: Dr Nejat Rahmanian, University of Bradford
Climate change is perhaps the most controversial global challenge that has emerged in the last decades and is a top agenda item in terms of its social, economic, political and technical impacts. The Paris agreement articulates the most recent international effort, negotiated by 196 countries, to combat climate change. The agreement aims to keep global warming to well below 2°C above pre-industrial levels and to pursue efforts to limit it to 1.5°C. The latest UN report published in Oct 2018 confirmed that atmospheric concentration of carbon dioxide is an increasing concern as it may cause global temperature rises to occur faster than it was previously expected. Historical meteorological data also shows that the average temperature of the earth has risen since the industrial revolution and the rise in global temperature is positively with unprecedented increases in greenhouse gas emissions and in particular carbon dioxide. However, there remains controversy over whether climate change is really occurring, how much has occurred, if greenhouse gases caused it, if any actions should be taken and, if so, what remedial actions should be and what is its economic impact. This is in spite of the fact that in the scientific literature there is a strong consensus that global surface temperatures have increased.
This presentation addresses the above, focussing on the UK and worldwide and presenting a number of possible engineering solutions to combat climate challenge.
CO₂ Capture using alternatives to amine-based capture agents and comparative studies
Speaker: Professor Chris Rayner, University of Leeds
Chris Rayner is Professor of Organic Chemistry at the University of Leeds, and is Founder Director of C-Capture Ltd., a University start-up which specialises in the development and application of highly efficient CO2 separation processes. C-Capture has developed a fundamentally new solvent based approach for separating CO2 from other gases. The technology significantly reduces energy requirements for the separation process, allows the use of inexpensive materials of construction, and has a substantially reduced environmental profile compared to current methods. Separation of CO2 from other gases is a key part of a low carbon economy, and examples will be discussed ranging from biomethane production by biogas upgrading, hydrogen production, and Europe’s first Bioenergy with Carbon Capture and Storage (BECCS) demonstration project with Drax Power at Selby.

"Green Energy/ Energy Transition"
The Acorn Carbon Capture and Storage Project
Speaker: Adam Jones, Costain
The Acorn CCS project is a low-cost, low-risk, scalable, carbon capture and storage scheme that will not only enable the cost efficient carbon capture and storage of current carbon emissions from the onshore gas facilities at St Fergus, but is also a key enabler for the Acorn Hydrogen project where North Sea natural gas will be reformed into clean hydrogen. It is designed to be built quickly, taking advantage of existing oil and gas infrastructure and a well understood offshore CO2 storage site. The system is designed to be an enabler of other capture and storage projects including provision of CO2 shipping facilities in Peterhead Port and repurposing the existing Feeder 10 pipeline to enable capture of CO2 from wider regions. The project is led by Pale Blue Dot Energy Ltd supported by study partners Shell, Total and Chrysaor with Costain providing onshore and offshore facilities engineering and consultancy services.
GERG (the European Gas Research Group) completes first stage of flagship biomethane project for CEN and the European Commission
Speaker: Marine Juge, ENGIE
GERG is pleased to announce the successful completion of the first phase of the European Commission funded project on removing barriers to biomethane injection in the natural gas grid and use as a vehicle fuel.
There is huge potential for biomethane transported in the gas network to play a significant part in decarbonisation of our energy system. As a substitute for natural gas, it allows use of existing infrastructure, while complementing intermittent renewable energy sources. However, some contaminants, inherent to the biomethane production processes, can be present in biomethane at a trace level. Depending on their concentration, these trace components (not present in natural gas) can interact with the gas chain infrastructure, and engines and boilers,
Two standards regarding biomethane have been published
- EN 16723-1: specifications for biomethane for injection in the natural gas network;
- EN 16723-2: automotive fuels specifications.
Limit concentration values are however lacking real world data. This can be a barrier for the development of biomethane in Europe as limits can be over prescriptive. For this reason, GERG and CEN launched a project in 2016 with the aim to identify the associated acceptable threshold for gas appliances and infrastructure. This paper present the results of the project.

"AGM & Technical Meeting"
Turbomachinery Configuration for LNG Projects - Conceptual Selection
Speaker: Mounir MOSSOLLY and Céline Belbol, TechnipFMC
Refrigerant compressors are the pumping heart of any liquefied natural gas plant. Those compressors are centrifugal type, they vary in size and configuration, being influenced by the context of the project. Steam turbines, gas turbines (heavy duty or aero-derivative) and/or electric motors are all possible options to drive the refrigerant compressors. A single shaftline could couple one, two or three compressor casings depending on the liquefaction process technology and process balancing needs, and also linked to the output power(s) of the possible drivers options. This paper will technically elaborate on how decisions are technically made for selecting the optimum turbomachinery configuration of refrigerant compressors in LNG plants. The paper will list the various criteria that could be initially set (and given an importance weight), which shall be used as a basis for evaluation and decision making. Technical constraints that could be faced will also be discussed. This paper builds on technical experience attained through working on several conceptual and pre-FEED studies for turbomachinery selection in LNG projects.

Formation of natural gas hydrates can cause serious problems during drilling and production operations in the oil and gas industry. This investigation reports the first study to predict hydrate formation using Aspen HYSYS® and HydraFlash softwares for various gas compositions and thermodynamic inhibitors (MEG concentrations at 10, 20, 30 and 40 𝑤𝑡% and Methanol concentrations at 10 and 20 𝑤𝑡%). Aspen HYSYS® is widely used in the petroleum process system containing thermodynamic inhibitor for this crucial purpose on prediction of solid phase behaviour. The simulated predictions are compared with results of available industrial and experimental data in the literature. It has been shown that HydraFlash software can accurately predict hydrate formation condition for a given industrial case, without having to carry out costly experimental work. This work also looked the effect of inhibitors and it appears that inhibitor type and concentration are determined according to condition of gas composition. MEG is consequently selected as the most ideal hydrate inhibitor for the industrial case. The hydrate formation prediction was carried out by HydraFlash for a high concentration of MEG inhibition at 40 𝑤𝑡% is up to 313 K with a pressure of 3111 𝑏𝑎𝑟. Finally, it is shown that both software packages are quite accurate and useful tools for prediction of hydrate for simple systems. However, HydraFlash can simulate more complex systems, including 13 different types of salts, while so Aspen Hysys covers sodium hydroxide as the common salt.

Energy transition: threat or opportunities?
Speaker: Christian Bladanet, TechnipFMC
Authors: Christian Bladanet and Marieke Maenhaut, TechnipFMC
For decades, the natural gas industry has been working toward improving the wellbeing of societies, by providing safe, affordable and abundant energy. During this journey, our industry has continuously developed technologies improving the efficiency and emissions of the gas processing facilities.
Today, clean, carbon free, green energies make all the talk. Is it the bell tolls of the natural gas industry?
This paper will present emerging ways to produce, store and transport carbon free or carbon neutral energies and how members of GPA Europe (producers, contractors and suppliers) can contribute to this movement, by building on our industry know-how and experiences.
The Shell Blue Hydrogen Process
Speaker: Matt Mardell, Shell Global Solutions
To meet net-zero-emission ambitions, low-carbon hydrogen production must increase rapidly. “Blue” hydrogen production from natural gas along with carbon capture, utilisation and storage (CCUS) is necessary to bridge the gap until large-scale hydrogen production using renewable energy becomes economic. The cost of carbon dioxide (CO2) already makes blue hydrogen via steam methane reforming (SMR) competitive against grey (without CCUS), and the Shell Blue Hydrogen Process (SBHP) further increases the affordability of blue hydrogen for greenfield projects.

Young Professional Session: "Digitalisation"
Boost your engineering workflow: Digitalization in the design and optimization of acid gas removal units
Speaker: Dr. Ralf Notz, Senior Technology Manager, BASF SE
The application of steady-state process simulation is well established in the engineering workflow for the design and optimization of production plants e.g. in the chemical industry or for oil- and gas processing. In an initial step, the plant configuration has to be set up in a process modelling environment (PME) like Aspen HYSYS®, Aspen Plus®, ProMax®, Pro/IITM or UniSim®. The flow sheet is defined by the combination of unit operations, which are connected by material streams and/or energy streams. Depending on the complexity of the unit operation model, different level of detail is required for setting up the process simulation. As example, an equilibrium stage model for a distillation column does not require geometric input like diameter or height, but only the number of equilibrium stages. In contrast, as example a detailed mass transfer model for an absorption column in an acid gas removal unit requires such geometric input. If the PME uses a sequential-modular solution approach, the proper specification of the latter unit operation model poses a challenge to the design engineer and usually requires numerous iteration steps until the required product specification is achieved and engineering guidelines, e.g. hydraulic limitations, are fulfilled. One part of this paper will discuss how an equation-oriented solution approach of the numerical problem can significantly reduce this effort by applying direct specifications of target values. In the same way, simulations for optimization of existing plants can be carried out very efficiently. Furthermore, an equation-oriented approach comprises the possibility of transferring the steady-state process simulation into a dynamic simulation.
The result of the steady-state process simulation is the heat and material balance for all material and energy streams. In a subsequent step, these data are used for creating technical data sheets for equipment. If both steps are carried out within one PME, the generation of technical datasheets may be partly or fully automated. However, when simulation models of special unit operations are only available in in-house or proprietary simulation tools, the workflow typically requires manual transfer of data between these tools and the PME. This procedure is inefficient, due to the time and resources required to manually transfer the necessary data. It also introduces risk of transcription errors, which can lead to inconsistencies in the heat and material balance.
The main focus of this paper is to illustrate how the engineering workflow can be improved by CAPE-OPEN. The CAPE-OPEN standard defines rules and an interface to allow communication between Computer Aided Process Engineering (CAPE) applications such as between a PME and a so-called process modelling component (PMC), which can be e.g. a thermodynamic model or the model of a unit operation. The implementation of the CAPE-OPEN interface as unit operation will be described for the example of BASF’s simulation tool OASE® connect for the OASE® gas treatment technology. As result, the full OASE® connect simulation can be embedded as unit operation into any CAPE-OPEN compatible PME. This implementation of the CAPE-OPEN interface is unique in the sense that the OASE® connect calculation is not carried out on the same computer or server as the PME, but on a BASF server. This approach allows for the protection of intellectual property of proprietary simulation tools.
The embedding via the CAPE-OPEN interface allows data to flow seamlessly between a PME and a PMC, so that the user can always produce a consistent heat and material balance. In the unavoidable case of changes in operating conditions or design parameters, such as the gas throughput or the feed gas composition, the updated simulation results are automatically reflected in all connected downstream documents, further enhancing efficiency. As result the application of the CAPE-OPEN interface allows savings in time and effort and facilitates effective work-sharing between offices worldwide.
Field operator and management training using Virtual Reality and a reactive digital twin
Speaker: Fabrice Rey, Technip France
With more complex plants in remote locations, operating companies have the challenge of finding new ways to train field operators that are less costly and more efficient. The offer of an introduction to plant operations and the acquisition of new operation skills without leaving the office is a personal development opportunity much appreciated by today’s personnel including managers and millennials.
As an illustration of the digital transformation of the Oil & Gas industry, this presentation will describe new technology that makes it possible to consider Immersive Training Simulators (ITS) using 3D Models to produce training solutions, reducing costs and schedule and improving safety.

"Troubleshooting poorly performing filters/coalescers"
Speaker: Martin Copp, Parker Hannifin
Filters and Coalescers are used in all walks of life where we produce, utilise or consume fluids are processed or used. Our cars (at least those with internal combustion engines) are only able to provide the reliable, economic and ever lower emissions that we expect as a result of the Fuel, Lube and Air filters they use. We are able to turn on the tap and safely drink fresh water as a result of the filtration and purification processes that the water goes through. Planes can fly at high elevation and temperatures well below freezing point due to the filters and coalescers used in the fuelling procedure. Milk, beer, wine and carbonated drinks are safe for us to consume due to harmful bacteria being removed via filtration.
Filtration and coalescing technologies are also widely used in every processing environment. The economics of hydrocarbon processing is heavily affected by the effectiveness of the filters and coalescers utilised. Plants are only able to produce on spec products and operate at the highest energy efficiency, highest throughput, highest reliability and lowest maintenance costs if the correct filtration and coalescing technology is installed and correctly maintained. Even when the correct filtration solutions are installed, operational issues can occur which affects the performance of this critical equipment. This seminar will look at the types of filters and coalescers commonly employed, operational issues that might be encountered and ways to identify what is causing the operational issues.
