This paper outlines the approach used at the Perenco UK (PUK), Dimlington gas terminal to efficiently and economically meet the Ozone Depleting Substances Directives - Montreal Protocol. Installing new equipment on live operational gas plants normally leads to plant shutdown and disruption to operations as well as incurring relatively high costs for brownfield modifications in a restricted area. On this project PUK successfully avoided installing new processing units. The Directives were met by assessing the performance of existing dew-pointing facilities evaluation of proven process technologies and an optimal combination of dew-pointing technologies to meet sales gas export specifications. The ensuing plant upgrade was executed via phased improvements at a fraction of the cost and schedule originally anticipated and with minimal disruption to ongoing terminal operations. The success of this project was recognised by a major I.Chem.E award and the terminal is now being further upgraded to increase the processing capacity for recently developed North Sea fields.
