以回收轻烃为目的的深冷装置中,当轻烃收率要求较高时,就需要达到一定的冷凝温度才能达到高产烃,高收率的目的。然而天然气中的CO2成为制约制冷温度的最大障碍。当CO2含量较高时(CO2含量大于1.5%mol),CO2在低温区极易发生冻堵。本文就如何在轻烃回收装置中有效的防止CO2冻堵谈一下自己的看法:
In order to recover light hydrocarbon for the purpose of cryogenic equipment, when the light hydrocarbon yield higher, you need to reach a certain condensation temperature in order to achieve high-yielding hydrocarbons, high yield purposes. However, natural gas CO2 becomes the biggest obstacle to the refrigeration temperature. When the CO2 content is high (CO2 content is greater than 1.5% mol), CO2 is prone to freeze blocking in the low temperature region. This article on how to effectively prevent the freezing of CO2 in the light hydrocarbon recovery unit to talk about their own views:
