Molecular sieves play a crucial role in the process of drying and purifying natural gas, often being the sole technology capable of achieving dew points compatible with cryogenic processes.
While these units are generally reliable, operational complexities arise when dealing with feed gases containing traces of H2S and / or CO2. The oversight of these contaminants can lead to significant spikes in regeneration, introducing significant operational challenges.
This paper explores solutions to minimize H2S and CO2 spikes during regeneration, with a focus on reducing energy consumption, thereby enhancing the efficiency and reliability of the process.
