Compressor-pump unit for provision with high pressure carbon dioxide of process of carbamide production

摘要

Compressor-pump unit for provision with high pressure carbon dioxide of process of production of carbamide includes connected to each other with system of technological pipelines first recuperation heat exchanger, with first output connected to output of separator output of which is connected to input of centrifugal compressor output of which is connected with first input of steam generator, first output of steam generator is connected to the first input of the second recuperation heat exchanger first output of which is connected to input of separator, and the second output – to pipeline for supply of gaseous carbon dioxide to synthesis of carbamide. Output of separator is connected to the first input of dehumidification block with output connected to the first input of the third recuperation heat exchanger first output of which is connected to input of electric heater output of which is connected to the second input of drying block. Second output of third recuperation heat exchanger is connected to the first input of condenser-evaporator first output of which is connected to collection vessel. First output of collection vessel is connected through throttle valve to the second input of the third recuperation heart exchanger. Second output of collection vessel is connected through pump to the third input of the third recuperation heat exchanger third output of which is connected to the second input of the first recuperation heat exchanger second output of which is connected to the second input of second recuperation heat exchanger. Second output of condenser-evaporator is connected to the second input of absorption water-ammonium refrigeration machine first input of which is connected to the second output of steam generator second output of which through pump is connected to the first input of adsorption water-ammonium refrigeration machine second output of which is connected through ammonia circulation pump to the second input of condenser-evaporator. Absorption water-ammonium refrigeration machine is connected to mains for cooling water supply.
