Hydrocarbon Freeing

It is important that the Hydrocarbons in a pipeline or process system are removed and the pipeline is rendered in an inert condition prior to any maintenance works, product change or de-commissioning.

Method for Hydrocarbon freeing depends on the properties of hydrocarbon to be removed (I.e. Oil, gas, viscosity, sour, sweet etc)
