Table 1. Eight constants of NRTL binary interaction parameters REACTION KINETICS The intrinsic kinetics equation of methanol dehydration to DME reaction can be expressed as [10]: The reaction equation of DME synthesis from Jehydrogenation of methanol was listed in equation (1). And vapor phase properties are calculated from the Peng-Robinson equation of state. The Peng- Robinson equation of state (PR) is a modification of the Redlich-Kwong equation of state and was published by Peng and Robinson in 1976. Only the critical data of pure substance are a prerequisite for application due to the plain pattern and the generalized parameters for PR equation. Moreover, analytical solutions could be observed mathematically, which makes PR equation

Fig-3: Change of temperature versus mol % DME Figure 2 shows change of composition versus tray position. The composition of DME decreases with increase of number of theoretical trays distillation column T-100. And Figure 3 shows change of temperature of the same column with change of composition of DME.
