摘要
有水合物存在的多相闪蒸计算对于水合物法分离技术非常重要.提出了一个进行气液液水合物四相闪蒸计算的新算法.其中气液(富烃相)液(富水相)三相平衡闪蒸计算采用PatelTeja状态方程,ChenGuo水合物模型用于气相与水合物相平衡的计算.此算法避免了求解复杂的方程组,因此使计算简单化.通过气体与纯水体系和有抑制剂体系的计算检验表明,此算法有很好的计算稳定性.
In this work, a new algorithm for performing vapor-liquid-liquid-hydrate multi-flash calculation was developed. Patel-Teja equation of state was used in performing the vapor-liquid-liquid （V-LHC-Lw） three-phase flash calculation and Chen-Guo two-step hydrate model was used for calculating the vaporhydrate phase equilibria. This method was rather simple as it avoided the complexity of simultaneous solution of a sophisticated group of equations. The proposed algorithm was tested on gas-pure water systems, gas-aqueous solution of alcohol systems, gas-aqueous solution of salt systems and gas system containing no free water. The calculation results showed that the proposed algorithm was stable and effective.
