SÉPARATION DU PÉTROLE, DE L'EAU, DU GAZ ET DES PARTICULES SOLIDES DANS LA PRODUCTION DE PÉTROLE ET/OU DE GAZ

摘要

An apparatus for separating oil, water, gas and solid particles from a hydrocarbon-containing fluid produced from an oil and/or gas production facility, the apparatus comprising a separation tank (102), the separation tank comprising: an inlet (101) for a multiphase hydrocarbon-containing fluid comprising oil, water, gas and solid particles to be separated; a solids outlet (226) connected to the separation tank; a first reservoir for containing an oil/water liquid mixture, from the multiphase hydrocarbon-containing fluid; a weir (124) at an end of the first reservoir; a first liquid outlet (228) of the first reservoir connected to a lower part of the separation tank; a second liquid outlet (230) of the second reservoir connected to the lower part of the separation tank; and a gas outlet (232) connected to the upper part of the separation tank.
