Acid gas preparation for enhanced oil recovery: techno-economic analysis of different dehydration processes
ABSTRACT The natural gas treatment plant is one source of CO2 emissions into the atmosphere. To tackle this issue, it is probable to inject CO2 into the wells and it can be used for enhanced oil recovery (EOR) application. However, the main setback is the high content of water in acid gas that could be converted to hydrate at high pressure in the pipelines. In this article, two different processes (solvent extraction, stripping gas) with two different solvents mono ethylene glycol (MEG), Tri ethylene glycol (TEG), are simulated in Aspen HYSYS. The stripping gas method is more efficient in terms of energy consumption, consuming 31.8% and 56.8% less energy than solvent extraction method for MEG and TEG solvents, respectively. Hydrate formation analyses showed that applying MEG as a solvent in the stripping gas method leads to a safer operation region. Economic evaluation depicts that the stripping gas method saves the total annual cost by 22.2% compared to solvent extraction. GRAPHICAL ABSTRACT
期刊介绍：
This international journal deals with fundamental and applied aspects of separation processes related to a number of fields. A wide range of topics are covered in the journal including adsorption, membranes, extraction, distillation, absorption, centrifugation, crystallization, precipitation, reactive separations, hybrid processes, continuous separations, carbon capture, flocculation and magnetic separations. The journal focuses on state of the art preparative separations and theoretical contributions to the field of separation science. Applications include environmental, energy, water, and biotechnology. The journal does not publish analytical separation papers unless they contain new fundamental contributions to the field of separation science.
