Static Optimization of the Process of Separation of Marketable Ethylene from Pyrolysis Products in a Multi-Column Rectification Unit
In the article the method of stage-by-stage optimization of static regimes of rectification columns in five-column system of separation of marketable ethylene from pyrolysis products is considered. The essence of the method is to calculate each of the columns of the system by a private problem in the form of maximizing the flow rate of the product stream, carrying in ethylene of a given concentration. Concentrations of ethylene in product streams of columns, except for given concentration in outlet stream, have been determined by simulation to obtain convergence of static mode calculation of system in given range of supply rate variation. Upon completion of the calculation, the total heat consumption for all columns of the unit and the specific heat consumption for the finished product are calculated.
