  • Method for processing pyrolysis gas prior to gas separation and method for producing low temperature cold in a vapor compression refrigerating machine during processing of pyrolysis gas prior to gas separation
    Patent number: 5946941
    Abstract: A method for processing pyrolysis gas prior to gas separation provides high economical efficiency due to low energy consumption for compression and low consumption of cooling water. This is due to the relatively low temperature of the pyrolysis gas and the low pressure losses during multistage compression, which in turn is determined by the organization of the processes of cooling by contact heat exchange between the pyrolysis gas and the washing water and operating liquid, by cooling them with an external medium in refrigerating machines and with a cold carrier in evaporators of absorption machines, and also by preliminarily cooling the washing water in the generators of those machines.
