YFC series composite polymerization inhibitor
The products are divided into yfc-1402, yfc-1404m and yfc-1418 according to their uses. Yfc-1402 polymerization inhibitor is mainly used for polymerization inhibition and scale prevention of depropanizer and debutanizer system of ethylene production unit. Yfc-1404m high-efficiency polymerization inhibitor is used for polymerization inhibition and scale prevention of decarburization five towers, decarburization eight towers, decarburization nine towers, ethylene and Styrene Separation towers and reboilers in large ethylene and styrene production units. Yfc-1418 is used for polymerization inhibition and scale prevention in high temperature parts of large ethylene production units.
