  • Patent number: 12337265
    Abstract: An apparatus for treating a multiphase hydrocarbon-containing fluid in an oil and/or gas production facility, the apparatus comprising: (a) an inlet for a multiphase hydrocarbon-containing fluid, wherein the inlet comprises a first pipe network configured to be connectable to a plurality of oil well heads in an oil field; (b) a separation system comprising: (i) a solids separator in fluid communication with the inlet; (ii) a solids outlet connected to the solids separator; (iii) a fluid separator in fluid communication with the solids separator, the fluid separator being configured to separate the remaining multiphase hydrocarbon-containing fluid into an oil phase, a water phase and a gas phase; (iv) an oil outlet connected to the fluid separator; (v) a gas outlet connected to the fluid separator; and (vi) a water outlet connected to the fluid separator; (c) a solids cleaning system connected to the solids outlet, wherein the solids cleaning system is configured to clean deposits of residual oil from the soli

  • Patent number: 11136874
    Abstract: Apparatus for separating solid particles from a hydrocarbon-containing fluid produced from an oil and/or gas production facility, supported on a wellhead or a riser connected to a wellhead, the apparatus comprising: a conduit for conveying a hydrocarbon-containing fluid from a wellhead or a riser connected to the wellhead; a solids separator in fluid communication with the conduit adapted to separate solid particles from the hydrocarbon-containing fluid, a solids outlet for outputting solid particles separated by the solids separator, a fluid outlet for outputting hydrocarbon-containing fluid separated by the solids separator; and an output conduit, coupled to the fluid outlet, for conveying the hydrocarbon-containing fluid from the fluid outlet into a production line attached to the wellhead.

  • Patent number: 10883353
    Abstract: An apparatus for, and a method of, separating oil, water, gas and solid particles (usually sand) from a hydrocarbon-containing fluid produced from an oil and/or gas production facility. In particular, this invention relates to an apparatus and method for the separation of oil, water, gas and solid particles from a well or group of wells using an integrated apparatus which significantly reduces the space required on the production platform or rig and recycles produced gas to improve process efficiency while reducing cost.
