新型冷冻脱水法是一种以周期切换的冷冻方式，它解决了传统冷冻法不能应用于在冰点温度下进行脱水操作的困难。将这种新型冷冻法应用于天然气的脱水预处理，可达到预定的脱水效果，保证了北方地区油气田天然气在冬季的不冻结安全输送；应用于轻烃分离工艺，不仅可以简化流程，减少设备，降低能耗，同时达到较高的C3收率。分析表明这一新工艺具有技术先进性与经济的合理性。
The new freeze-dehydration method is a cycle-switching method of freezing, which solves the traditional freezing method can not be applied to freezing temperatures at freezing temperatures difficult. Applying this new freezing method to the dehydration pretreatment of natural gas can achieve the expected dehydration effect and ensure the non-freezing transportation of the natural gas in the northern oil and gas field in winter. The light hydrocarbon separation process can not only simplify the process, reduce the equipment, Reduce energy consumption, while achieving higher C3 yield. Analysis shows that this new technology has advanced technology and economic rationality.
