CO2 recovery from CO2 removal unit at GL1Z plant.

Author(s) : FRIHA H.

Summary

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 CO2 emissions from industrial plants. The liquefied natural gas plant GL1Z was designed to transform about 10.5 billion cubic meter per year of natural gas containing a considerable amount of carbon dioxide (about 50 000 tons per year). Ahead of the liquefaction process, carbon dioxide is removed by absorption using an MEA solution in order to avoid its freezing in the cryogenic sections. The regeneration of the MEA solution is carried out in the regeneration column where CO2 is sent to the atmosphere. This paper presents in detail a new process for recovering the actual carbon dioxide CO2 sent to the atmosphere from the GL1Z plant in order to be used in the neighbouring plants. These 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. The 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.
