摘要
根据油气烃类体系的组成特点和相态特征 ,提出了气 液 固三相相平衡的计算方法。采用状态方程描述气相和液相的相态变化 ;而将固相视为非理想的固态溶液 ,用正规溶液理论来描述其非理想性。实例计算结果表明 ,该方法适用于石油开采、集输和加工过程中的气、液、固三相相态模拟研究 ,也可以用于石蜡、沥青等有机固相沉积的研究。
A calculation method of gas liquid solid three phase equilibrium is presented based on the characteristics of composition and phase behavior of an oil and gas system. The phase behavior of both the gas and liquid are calculated by the equation of state, and the solid phase is assumed to be a non ideal solid solution, which can be described by regular solution theory. A practical modeling example result showed that this method could be used in the research of gas liquid solid three phase equilibrium in production, transportation and oil and gas processing as well as in solid precipitation of wax and asphaltene.
