| Low
Sulphur Heavy Stock (LSHS) and Heavy Petroleum Stock (HPS) are residual fuels
produced after processing of indigenous crude. These fuels have high pour points
and require special handling arrangements. Unlike Furnace oil, these fuels do
not have a limit on their kinematic viscosity. Kinematic viscosity for these fuels
is measured at 100OC. These are used in lieu of FO in the same applications where
furnace oil is suitable. LSHS has additional advantage of having low sulphur content
and high calorific value. These conform to IS:11489-1985 specifications for Heavy
Petroleum Stock grade I. |
