Calculation of ethylene region of chemical technological complex for processing of cracking and pyrolysis gases

Abstract

To create a chemical-technological complex for the joint processing of cracked gases and pyrolysis gases, the technique of its design was developed. Based on the design capacity of the pyrolysis and cracking units, mass flows of cracked gases and pyrogas entering the chemical-technological complex have been calculated. A scheme has been developed for the proposed complex. To reduce the dimension of the design task, the whole complex was divided into a separate region. Based on the stoichiometric and kinetic models, the calculation of material balances for all processes included in the largest ethylene region has been carried out. The technological parameters were taken from the operated industrial units and processes on the stage of design. The industrial productivity of reactor elements by the targeted products has been determined.
