METHOD OF ACID GAS REMOVAL FROM UNTREATED GAS AND ADDITIVE WITH ANTICORROSION AND FOAM-REDUCING EFFECT FOR ADDITION TO AMINE SOLUTION FOR ACID GAS REMOVAL

摘要

FIELD: chemistry. ^ SUBSTANCE: method involves interaction of untreated gas with water solution of 2-(2-aminethoxy)ethanol containing organopolysiloxane composition with polyoxyalkylene group, and fine silica powder. Additive for water solution of 2-(2- aminethoxy)ethanol includes organopolysiloxane composition with polyoxyalkylene group, and fine silica powder in the amount of 0.1 to 5000 parts per mln, while the water solution includes 40 wt % or over of 2-(2- aminethoxy)ethanol. ^ EFFECT: anticorrosion protection of steel parts of a device for acid gas removal with foam-reducing effect. ^ 7 cl, 5 dwg, 2 ex
