减小甲醇合成催化剂床层温差的工艺设计

Renovation Design for Methanol Converter and Process to Reduce Temperature Difference between the Catalyst Beds

ICI低压甲醇合成工艺中,合成塔内冷热气体直接混合传热,造成催化剂床层间温差较大,对催化剂及甲醇合成都有不利影响。本文对造成问题的原因进行了分析,提出了改进设计。

With ICI methanol synthesis process under low pressure, the mixing and heat transferring between hot part and cold part of syngas were directly taking place inside the converter, resulting in great temperature difference between the beds, which had negative influence for catalyst itself and synthesis reaction. In this paper, the author analyzes the causes and puts forward the renovation design.
