In the simulation the mixed Refrigerant cycle (MRC) to liquefy the natural gas, the calculation of property parameters of the natural gas and the mixed refrigerant (MR) is unavoidable and the solution of the state equation is a important. For the natural gas and MR in the process, the precise of the enthalpy and entropy of the two mixtures calculated by the LKP equation is high. In this paper, the solution method of the LKP equation is discussed, and a method with good convergence is designed. The relation between enthalpy and temperature, pressure, mole percentage of the natural gas and MR is calculated using LKP equation. The calculation method is also suit for other substances.
