Desanding, flow splitting, degassing vessel

An atmospheric vertical oilfield tank for preconditioning an oilfield fluid stream entering the inlet to production or processing facilities by desanding, degassing and hydraulically splitting the flow of the liquid into evenly divided exiting fluid streams comprising:

• a vertical liquid separator tank for receiving a liquid steam and separating entrained solids and gases from the liquid stream to create a separated liquid stream,
• a plurality of vertical flow dividing tubes located within a body of the tank communicating with separate effluent discharge piping designed to carry the separated liquid stream out of the tank to separate vessels downstream of the tank, and the upper ends of each vertical flow dividing tube being open and at approximately the same elevation within the tank so that the separated liquid stream flowing from the body of the tank into the open upper ends of the vertical flow dividing tubes is divided into separate liquid flow streams of approximately equal volumes, each separate liquid flow stream being carried as an individual divided flow stream by a respective effluent discharge pipe out of the vertical liquid separator tank.
