摘　　要：甲醇装置采用乙烯装置裂解单元的低压甲烷为原料,原料中烯烃含量偏高的情况时有发生,影响甲醇装置的安全平稳运行。甲醇装置在脱硫槽更换了具有加氢能力的B脱硫剂后,出现了压差逐渐升高的情况,通过现场验证和实操摸索,并采用低温加氢工艺技措,有效解决了脱硫槽压差升高的瓶颈问题。Methanol plant uses low pressure methane from the cracking unit of ethylene plant as the raw material.There have been times when the olefin content of the raw material was high,affecting the safe and stable operation of the methanol plant.After replacing the desulfurizer in the desulfurization tank of methanol plant by desulfurizer B with hydrogenation capacity,the pressure difference gradually increased.Through field verification and practical operation,low temperature hydrogenation technology was used to effectively solve the bottleneck problem of pressure difference increase in the desulfurization tank.
