油气田生产的天然气大都含有饱和水蒸气。在天然气轻烃回收的生产过程中，由于温度、压力的变化，使其在管路或设备内发生冷凝、积聚，生成水化物而阻塞管路、阀门、设备，因此预测天然气含水量和水化物生成过程是很重要的。近年来，由于分子筛吸附脱水成本高，又重提注入甲醇控制轻烃回收浅冷和深冷装置的水化作用。为此，探讨了用注入甲醇方法轻烃回收深冷装置中控制水化作用的工艺过程，并与分子筛脱水装置的投资和操作费用进行了对比，认为利用甲醇控制轻烃回收装置中的水化作用，在一些条件下更为经济合理。
Natural gas produced in oil and gas fields mostly contains saturated water vapor. In the process of gas light hydrocarbon recovery, due to the change of temperature and pressure, it condenses and accumulates in the pipeline or equipment to generate hydrate to block pipeline, valve and equipment, so the prediction of natural gas moisture and hydrate The build process is very important. In recent years, due to the high cost of molecular sieve adsorption and dehydration, but also re-injection of methanol to control light hydrocarbon recovery light and cryogenic plant hydration. Therefore, the process of controlling hydration in light hydrocarbon recovery cryogenic plant by methanol injection was discussed. Compared with the investment and operation cost of molecular sieve dehydration unit, methanol was used to control the hydration in light hydrocarbon recovery unit Role, under some conditions more economical and reasonable.
