Description
Special Features
HYCOM LS grades are low sulphur high viscosity oils which can be used in syn gas compressors of make like Cooper Bessemer, Nuovo Pignone etc. The product will is compatible with syn gas operation at high pressure and there will be minimum risk of oxidation. The risk of catalyst poisoning is eliminated as the product has a very low sulphur content. (<0.25% wt)
