PROCESS FOR THE TREATMENT OF UNSTRIPPED CONVERTED GAS FROM CARBON DIOXIDE

摘要

A process for the treatment of unstripped converted gas from carbon dioxide comprises the gas direction to the lower housings of two absorbers, sprayed by hot absorbent solution, separation from droplets of the absorbent solution and direction for fine cleaning to metanator, and also regeneration of the spent absorbent solution to two content levels of residual fixed "semipoor" and "poor" carbon dioxide. The spent absorbent solution is regenerated by series circuit in regenerators of high and low pressure.
