Study On Process Simulation And Research For Methanol Distillation System

Methanol , the very important basic product of C1 chemical industry .Base on industrial research and experience, the process of methanol distillation is analyzed, and above all, a new concept of high pressure processing and low pressure processing is defined through real industry data and simulations of plant data. The new configuration helps to handle problems encountered in many factories in China and to support designing working of a lots chemical design institute. Compared with industrial examples tell us how the new concept works and the possibility of combining process to give more opens to solve engineering problems.The composition data of crude-methanol gas has great influence on the result of simulation. So we selected the very hard scope of that to test our simulation. The considerably accurate results can be obtained by using thermodynamic package of ALCOHOL.Moreover, some deeply researches have been made in this paper by using the data of pilot plants, several important parameters and their influence factors of methanol production quality have been involved which are including top and bottom temperature, reflux ratio of column, etc.Different internals of methanol distillation column have been discussed in this paper. The different internals column processing data have been compared through process simulation in this paper. The functions of various of distillation sub-processing have been involved also.As for whole methanol distillation system design, we believe that there should be new concept of process designing and new way of energy saving. We developed new processing of methanol distillation. Deep- researched and discussed in this paper on the basis of the data of new concept of methanol distillation. This paper also bring us the way of building a new chemical design package for methanol distillation.
