SU1611415A1 - Method of cleaning flue gases - Google Patents

Abstract

The invention can be used in the chemical industry, as well as in agriculture and in the fleet, for example, in the carriage of goods of plant or animal origin, the flue gases of ship’s power plants can be cleaned and separated to produce carbon dioxide-rich gas mixtures. used as a fumigant. The invention makes it possible to simplify the process and also makes it possible to utilize the flue gases to produce a fumigant. The method involves filtering flue gas, cooling, absorption of carbon dioxide, regeneration of a saturated absorbent with its subsequent return to the cycle and release of regeneration gases, while the regeneration gases are mixed with the gases obtained after absorption in a volume ratio of 1: (1-3), and the resulting mixture is dried by cooling to a temperature of 0-10 ° C and a residual water content of 0.4-1% by volume. 1 tab.

Description

The invention relates to methods for absorption purification and flue gas separation, and may find its use in chi; Domestic industry, agriculture for fumigation of cargo: /: grow het: animal and animal origin when transported on ships.
