Crude Oil/NGL Stabilizers

ETI provides treatment systems to process and stabilize hydrocarbon liquids for storage, transport, or process requirements. The process equipment consists of standalone vessels and skid-mounted modules.

The components of a crude oil or condensate stabilizer consist of heat exchangers, a stripping tower and a reboiler. Heat is applied to the crude/condensate and light ends are distilled/stripped from the stripper. A rectification section, reflux condenser, and air cooler may be employed. The off gases are re-compressed or disposed of to flare or incineration.

Reasons for Crude Oil/Condensate Stabilization
In order to safely transport and store hydrocarbon liquids, it is often necessary to remove the low molecular weight hydrocarbon components. This process known as stabilization minimizes flashing gases while the hydrocarbon liquid is in storage. Typically, crude oil has a Reid vapor pressure of 8-13 psi after stabilization. The hydrocarbon liquid is stripped of its light ends, principally methane and ethane, while conserving the heavier components as the fluids are heated in the reboiler. A reboiler package consisting of heat exchangers and an electric or gas fired reboiler distills off the light ends.
