Used and Surplus Vertical Vessels

Welcome to Surplus Energy Equipment, the best website in finding used oil & gas equipment! SEE has made searching used equipment easy and has created the tools to put the search at your fingertips without the hassle of making phone calls and requesting additional information.

What is a Vertical Vessel?

A vertical vessel or a vertical separator is a vessel for the bulk removal of liquids or solids by gravity. Operators prefer to utilize vertical separators over other separators when the well streams have large liquid to gas ratios, constant flow, and small liquid surge characteristics (high gas/ low liquid). Vertical separators are also preferred when well streams have sizable quantities of sand, mud, or other related substances as well as process flow streams, which are characterized by large instantaneous volumes of liquid or slugs. Lastly, when there are horizontal space limitations, but little or no vertical height limitations (i.e. offshore platform), vertical separators would be a good, space-saving option. Check out our Horizontal vs. Vertical Vessel blog for more information on determining the best vessel for your application.

These separators may go by many names like oil-water separator, three-phase separator, two-phase separators, but functionality is all relatively the same.
