【Abstract】 To solve problems in methanol distillation Process, reducing the process like mass balance, gas - liquid phase equilibrium, summation of mole fraction and enthalpy balance equation by a Modified Tridiagonal Matrix Method. The obtained temperature profile and composition distribution on various theoretical plates in methanol distillation tower are in agreement with the values from practical determination. In methanol distillation calculation the Modified Tridiagonal Matrix Method has the merits in small memory space, Less computation time and quick and steady convergence.更多还原
