Phase Separator on Oil and Gas Facilities

{0 Comments}

Fluids outputted by the wellhead are made of form many different compounds of hydrocarbon and each compound has its own physical characteristic. The fluids flow from high temperature and high pressure reservoir surface facilities so its temperature and pressure will decrease. Gases from the well stream or evolved in liquid will flow in high speed …
