TOTSUCAT® LOAD & GO™ Catalyst Sulfiding
Eurecat’s TOTSUCAT® LOAD & GO™ ex-situ ACTIVATION service successfully activates hydroprocessing catalyst and enables refiners to simplify and accelerate their hydrotreating unit start-up procedure.
Totsucat® activated catalyst can also be passivated to allow for loading under air. Using ex-situ pre-activated catalyst Totsucat® (including Totsucat CFP®) LOAD & GO™ service will save money, reduce start-up time and associated CO2 emission, and it moves the potentially hazardous sulfiding process away from the refinery.
Sulfiding Comparison
Totsucat® Types
Totsucat G: Naphtha
Totsucat D: ULSD
Totsucat E: Vacuum Gas Oil
Totsucat N: Hydrocracking Pre-Treat
Totsucat HC: Hydrocracking
Totsucat TG: Tail Gas
Totsucat SG: Syn-Gas
TOTSUCAT® HC-AP®
Totsucat® HC-AP® eliminates the use of ammonia during hydrocracking catalyst start-up while still controlling the catalyst exotherms.
CFP - Cracked Feed Protection
The CFP (cracked feed protection) process is an extension of the Totsucat® catalyst activation process. The CFP treatment allows for the immediate introduction of cracked stocks instead of waiting 2-3 days. The CFP process includes the catalyst sulfiding, activation, and cracked feed protection.
Loading under air
Eurecat offers various type of Totsucat post treatment allowing safe loading under air. Depending on the catalyst type and the type of application either AirSafe or EZ Load can be proposed.
