求助大神一个单词 contactor? As part of the HRS development, TechnipFMC PT has designed a simple contactor column that performs this function. It is a small tower that has the heavier cold liquid flowing down counter-current with the lighter gas flow up. Heat and mass transfer therein make two Demethanizer feeds - a top cold/light gas and a lower, heavy, warmer liquid - that are much more thermodynamically ideal. The savings in the installed cost of the cold Demethanizer and in refrigeration energy far outweigh the cost of this small contactor. 有大神能告知这里的contactor到底是是个什么吗?不胜感激! 查看更多3个回答 . 5人已关注
