Conceptual Study for Sour Gas Processing Emphasized on Acid Gas Injection

摘要

Despite of its popularity as cleaner fuel natural gas exist in the ground occasionally contaminated with high contents of acid gases. Venting the acid gases from the resource is somehow unviable in the near future while many countries all over the world has pledged to reduce their greenhouse gas emissions. This study presents a conceptual approach for processing natural gas to address the acid gas injection option as the environmentally friendly manner to deal with in the development of highly contaminated natural gas, regardless the importance of the acid gas injection, storage, and field economics. Preliminary selection and comparison of gas processing technologies has been evaluated considering the proven technologies as well as the emerging cryogenic technologies. As the results a potential cost saving which may benefit to the field economics and higher process performance can be achieved by the emerging cryogenic technologies compared to current proven technologies as base case. The challenges is how making the technology feasible at commercial scale.
