öljyyhdyskaasun

öljyyhdyskaasun is a Finnish term that translates to "oil condensate gas". It refers to the mixture of light hydrocarbons that vaporize from crude oil when it is brought to the surface and the pressure is reduced. This gas is typically separated from the liquid crude oil at the production site.

The composition of öljyyhdyskaasun varies depending on the source crude oil, but it commonly includes methane, ethane, propane, and butane. It may also contain small amounts of heavier hydrocarbons and non-hydrocarbon gases like nitrogen and carbon dioxide. The presence of these heavier components distinguishes it from natural gas, which is primarily methane.

öljyyhdyskaasun is often processed further to recover valuable components like natural gas liquids (NGLs), such as propane and butane, which are used as fuels or feedstock for the petrochemical industry. The remaining gas, largely methane, can be used as fuel or reinjected into the reservoir.

The extraction and processing of öljyyhdyskaasun are integral parts of crude oil production, contributing to the overall efficiency and economic viability of oil fields. Its management is crucial for environmental reasons, as unrecovered light hydrocarbons can be significant sources of volatile organic compounds.
