| Abstract: | Cold box in liquid nitrogen wash is used to remove such impurities as CO,CH4,Ar from the purified gas at outlet of molecular sieve and at the same time,an MP nitrogen is added into the wash gas to make a syngas with a H2 /N2 ratio of 3/1.The problems appeared in the cold box during the operation and factor affecting the stable running of the cold box are analyzed and corresponding optimized operation method proposed. |
