Heavy Fuel Oil (HFO)

Heavy fuel oil, otherwise called residual fuel oil is comprised mainly of atmospheric pipestill bottoms blended with heavy virgin naphtha and vacuum gas oil to produce the final heavy fuel oil product. The company supplies various grades of utility grade fuel oil with sulphur content ranging from 1.8 – 3% wt. An additional grade namely Intermediate Fuel Oil (IFO-380) with a kinematic viscosity specification of 380 cst is also produced.
Until recently, HFO was the primary product used by the electric power generation companies as it presented a low cost – high availability option to generate electricity. However, with the introduction and availability of LNG as a clean alternative fuel, the sector has significantly decreased its use of HFO. Petrojam is configured to produce significant quantities of the fuel and alternative markets have been developed as an imperative to sell the product. In addition, crude oil quality has been adjusted in order to produce very low sulphur fuel oil for the bunker fuel market. Petrojam’s MARPOL compliant Residual fuel oil is in high demand as bunker fuel (fuel for ships). Local industrial entities also use the product as boiler fuel.


The vacuum pipestill produces two grades of penetration asphalt from the atmospheric pipestill bottoms: 60/70 and 85/100. Asphalt is used in the construction of roads; on roofs as a sealant and to water proof surfaces.

Marine Gas Oil (MGO)

Marine Gas Oil is a heavier grade of gas oil that is produced directly from the Atmospheric pipestill tower. MGO does not undergo the hydrofining process. It is sent directly to tankage from the atmospheric pipestill. MGO is used as a bunker fuel (fuel for ships).

Jet Fuel

The Jet Fuel sold at our airports is a kerosene-based fuel produced in the same way as Kerosene Oil but under stricter quality requirements for use in jet aircraft.
