摘要:
Methods and systems for processing crude oil may include adding water to crude oil, for example, in a desalter, to produce hydrocarbon and brine and a rag layer emulsion, which may include hydrocarbon and brine and solids. The emulsion may be modified, including adding one or more of additional hydrocarbon and, a demulsifier, a reverse demulsifier, a coagulant, and a flocculant, for example, in a mixer. The modified emulsion may be directed through a dead-end filter assembly to remove solids.

摘要:
A system and method treat oilfield produced water by two-stages of hazardous sulfide treatments. In an embodiment, a two-stage oil and gas field produced water treatment system includes an oil removal vessel. The oilfield produced water is introduced to the oil removal vessel. The oil removal vessel removes a portion of the hydrocarbons from the oilfield produced water to provide a reduced oil produced water. In addition, the system includes an iron sponge. The reduced oil produced water is introduced to the iron sponge, and the iron sponge removes a portion of the hazardous sulfides from the reduced oil produced water to provide a reduced sulfide produced water. The system also includes a stabilized sodium percarbonate solution. The stabilized sodium percarbonate solution is mixed with the reduced sulfide produced water to remove a portion of the hazardous sulfides from the reduced sulfide produced water to provide a treated produced water.

A mobile apparatus and method for recycling an invert emulsion based drilling fluid, in which the invert emulsion based drilling fluid includes an oleaginous component and an aqueous component. The apparatus includes an emulsion breaking tank, a water treatment tank, a filter press, and hydrocarbon filters. The method includes: mixing said invert emulsion drilling fluid with a emulsion breaker, wherein the emulsion breaker is a mixture of an alkyl glucoside and an alkane sulfonate; and separating the oleaginous component of the invert emulsion drilling fluid from the aqueous component of the invert emulsion drilling fluid. The method preferably utilizes an emulsion breaker that is a combination of an anionic surfactant, a nonionic surfactant and an alkyl polyglycoside surfactant.
