A gas engine is an internal combustion engine which uses blast furnace gas, producer gas, natural gas and others as fuel.

A gas flare, alternatively known as a flare stack, flare boom, ground flare, or flare pit is a gas combustion device used in industrial plants such as petroleum refineries, chemical plants and natural gas processing plants.

A tank, compartment or container is gas free when sufficient fresh air has been introduced into it to lower the level of any flammable, toxic, or inert gas to the level required for a specific purpose, e.g. hot work, entry, etc.

The procedure of removing dangerous and explosive gases from the interior of tanks (usually vapours originating in the cargo of oil tankers and chemical carriers).

Portable instruments for measuring the concentration of hydrocarbon gas in inerted and non-inerted atmospheres, of other toxic gases and oxygen.

Power plants use natural gas, the cleanest fossil fuel available. They have lower emissions thereby minimising the environmental impact. Gas power plants can run on natural gas, liquefied natural gas and liquefied petroleum gas.

Separation of oil and gas involving removal of impurities and gas condensate from natural gas.

Wärtsilä GasReformer is the solution for utilising gaseous fuels that either contain large amounts of heavier hydrocarbons or vary in their composition.

CLIPPER VIKING is an ice-strengthened gas tanker type 2G, designed to carry ethylene, vinyl chloride monomer (VCM), ammonia, propylene oxide, propane, butane and other liquefied gases.

A refinery process to convert natural gas or other gaseous hydrocarbons into longer-chain hydrocarbons, such as gasoline or diesel fuel.

Removal of impurities from natural gas such as water, sulfur compounds and carbon dioxide.

Also known as a combustion turbine. Fuel is sparayed into compressed air which ignites and causes a high pressure gas flow which drives the turbine impellers.

A gas-cooled reactor (GCR) is a nuclear reactor that uses graphite as a neutron moderator and a gas (carbon dioxide or helium in extant designs) as coolant.

A space not arranged or equipped in an approved manner to ensure that its atmosphere is at all times kept in gas-safe condition. IMO Codes defines many gas-dangerous spaces on board gas carriers, chemical carriers etc.

Gas-diesel engines utilise the diesel combustion process in all operational modes.

Gaseous diffusion is a technology used to produce enriched uranium by forcing gaseous uranium hexafluoride (UF6) through semipermeable membranes.

A chemical process that converts a solid fuel into gases.

Flexible material used to pack joints in machinery, piping, doors, hatches, etc, to prevent any leakage.

Gasoline or petrol is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines.

Gasoline gallon equivalent or gasoline-equivalent gallon is the amount of alternative fuel it takes to equal the energy content of one liquid gallon of gasoline.
