汽油等油品在储运过程中会有部分轻烃组分挥发进入大气,与空气混合成为油气。这部分油气在储运过程中难免会产生环境污染、能源浪费等问题,利用复叠制冷循环制取低温来冷凝油气中的轻烃组分,实现油气回收、节能减排已成为业内研究的热点课题之一。冷凝法油气回收装置的能耗是研究者普遍关心的问题,本文提出了一种冷凝法油气回收系统,计算了温度变化时冷凝负荷的变化,从理论上分析了机组能耗随环境温度变化的规律。并指出了降低机组能耗的关键。
During the storage and transportation, some light hydrocarbon components will volatilize into the atmosphere and mix with air to become oil and gas. This part of the oil and gas in the process of storage and transportation will inevitably produce environmental pollution, energy waste and other issues, the use of cascade refrigeration system to obtain low temperature to condense the light hydrocarbon components in oil and gas to achieve recovery of oil and gas, energy saving has become a hot topic in the industry One of the topics. The energy consumption of condensate recovery device is a common concern of researchers. In this paper, a condensate recovery system is proposed to calculate the change of condensing load when temperature changes. The energy consumption of the unit is analyzed with the change of ambient temperature law. And pointed out that the key to reduce unit energy consumption.
