摘　　要：针对CO_2气田气资源开发,用MPR状态方程建立了CO_2气田气热力学性质计算模型,并用三对角矩阵法对精馏过程进行模拟计算。结果表明通过简单的精馏过程可以生产出纯度为99.99％以上的高纯CO_2气体。This work is aimed at the problem of exploiting carbon dioxide-reservoir gas resources. A modified Peng-Robinson equation of state(MPR) is proposed to calculate the thermodynamic properties of carbon dioxide-reservoir gas, and tridiagonal matrix method is used to simulate the distillation process. Carbon dioxide gas of high purity can be produced by a simple distillation.
