介绍了一种在不影响天然气碳氢化合物含量的情况下,选择性脱去高压天然气中水分的紧凑型高压系统。常规的水合物抑制或脱水系统只能在一定压力下工作,脱水的精度相对粗糙,不能选择性地脱去水分,因此,一些冷凝的水合物在水露点条件下也同时被脱去。新技术的提出为任何海上及陆上天然气的生产及处理和海底石油和天然气的生产找到了发展途径。利用超音速喷嘴精确估算脱水效率,以此控制超临界流中水合物的模拟技术,需要一个与热动力性质发生器相关的模拟模型来预测多相流条件下的脱水效率。该模型给出在各种条件下天然气脱水的计算机模拟结果,并与传统技术进行了比较。
A compact high-pressure system that selectively removes water from high-pressure natural gas without affecting the natural gas hydrocarbon content is introduced. Conventional hydrate suppression or dehydration systems work only under pressure, dehydration is relatively coarse and can not selectively remove moisture, so some condensed hydrates are also removed at the same time in water dew point conditions. The introduction of new technologies has found a way forward for the production and processing of any offshore and onshore gas and for the production of seabed oil and gas. The use of supersonic nozzles to accurately estimate dehydration efficiency and to simulate hydrate formation in supercritical flows requires a simulation model associated with the thermodynamic properties generator to predict the efficiency of dehydration under multiphase flow conditions. The model gives the results of computer simulation of natural gas dehydration under various conditions and compares it with the traditional techniques.
