CO_2 RECOVERY FROM CO_2 REMOVAL UNIT AT GL1Z PLANT

摘要

Algeria which has ratified the Kyoto Protocol on the reduction of greenhouse effect gases to the atmosphere is making major efforts for the environment protection such as preventing the carbon dioxide CO_2 emissions from industrial plants.rnThe liquefied natural gas plant GL1Z was designed to transform about 10.5 billions cubic meter per year of natural gas containing a considerable amount of carbon dioxide (about 50,000 Tons per year).rnAhead of the liquefaction process, carbon dioxide is removed by absorption using an MEA solution in order to avoid its freezing in the cryogenic sections.rnThe regeneration of the MEA solution is carried out in the regeneration column where CO_2 is sent to the atmosphere.rnThis paper will present in detail a new process for recovering the actual carbon dioxide CO_2 sent to the atmosphere from the GL1Z plant in order to be used in the neighboring plants.rnThese plants will use this product either in the synthesis of the urea, the production of methanol or in the food industry as an alimentary agent.rnThe implementation of this process will contribute directly to the reduction of greenhouse effect gases in addition to the significant economic benefits for the GL1Z plant.
