Cyntrol® provides a needed tool for the refinery. As refineries are being driven to lower quality crudes, problems associated with nitrogen are on the increase. A major problem is the generation of cyanide in the various thermal cracking units, primarily the catalytic cracking and coking processes.
Cyntrol® is used to chemically scavenge free cyanide which is generated in thermal cracking processes (fluidized catalytic cracking units, hydrocrackers, delayed cokers, fluidized cokers, etc.) in refineries, converting it to thiocyanide, which is easily handled in the refineries' water treatment facility. If the free cyanides are not scavenged, they can contribute to corrosion within the units , downstream units, and/or send the free cyanide to the refinery's waste water plant.
