Commercial and Military-Grade Jet Fuel

Lima Refinery has the capability to produce Commercial (Jet A/Jet A1) and Military (JP8) grade aviation fuels.


Benzene is used in the production of other industrial chemicals that make plastics and resins, and nylon and synthetic fibres. Benzene produced at the Lima Refinery is used to make some types of rubbers, lubricants, dyes, detergents, drugs and pesticides.

Butane and Butylenes (BB) Mix

BB Mix is primarily a feedstock in refineries with alkylation units for making gasoline. It is used as a blending component with gasoline blendstocks.

Decanted Oil

Decanted oil (DCO) is a valuable solvent used in the Lima Refinery’s hydrotreating unit for controlling carbon solids.

Petroleum Coke

Petroleum coke is a solid residue of almost-pure carbon that remains after heavy oil fractions are cracked to produce lighter hydrocarbons. The Lima refinery produces anode-grade petroleum coke, which is calcined (a thermal process) to remove the volatile fraction to make carbon blocks, and then is used as an anode in the production of aluminum. The coke is transported by truck and railcar to markets.

Propane, Butane, Isobutane and other Natural Gas Liquids

Cenovus manages proprietary and third-party volumes of propane, butane, isobutane and other natural gas liquids.

NGL mix is acquired and sold for processing and subsequent sale as specification products (propane and butanes). Sales and purchases of all products are made on a spot, monthly or term contract basis.


Propylene is a major commodity in the petrochemicals industry. It is used as a building block in producing polypropylene products ranging from rope to clothing. Propylene is also used in the production of industrial chemicals including acetone, and as a fuel gas in industry.


The majority of the sulfur Cenovus produces and sells is converted to sulfuric acid (H2SO4), the most common industrial chemical produced in the U.S. Sulfuric acid is mainly used in the production of phosphate fertilizer, in metal leaching applications and the production of various chemicals


Toluene is a common solvent used to remove paint, silicon sealant, glues and adhesives, and lacquers. It is used in the manufacturing of polyurethane foam and explosives, and as a petrochemical feedstock and an octane enhancer. It is used within the Lima Refinery to make gasoline.


Transmix is a byproduct of refinery operations. It is created by mixing different products, usually gasoline and diesel fuel, during pipeline transportation. At transmix processing plants, it is separated into products such as unleaded gasoline and diesel fuel.
