摘要： The disclosed technology relates to methods of inhibiting corrosion in reaction chambers configured for hydrothermal reaction of feeds containing a heteroatom. An embodiment of such a method comprises providing a feed stream comprising a phosphorus-containing material, an alkali metal compound, water, and a corrosion-inhibitor. The embodiment additionally includes introducing the feed stream and oxidant into a reactor chamber and oxidizing the phosphorus-containing material at an oxidation temperature greater than about 374° C. and an oxidation pressure exceeding about 25 bar, wherein the reactor chamber has inner surfaces comprising a material that corrodes when in contact with a phosphorus compound within the reactor. The embodiment additionally includes selectively reacting the corrosion-inhibitor with phosphorus within the reactor, thereby precipitating in the reactor chamber a phosphorus-containing solid inorganic compound. The embodiment further includes forming in the reactor chamber an alkali salt melt and carrying away from the reactor chamber a mixture comprising the solid phosphorus-containing inorganic compound and the alkali salt melt.

摘要： Produced water from a crude oil or natural gas production process is purified using a membrane purification system for petroleum production, agricultural, commercial and domestic uses. The produced water is pretreated to remove, at least, particulates and oil from the produced water. The minimally pretreated water is then purified in a membrane purification system that is operated at conditions such that contaminants are removed. In particular, the membrane purification system is operated with pH adjustments to allow boron and ammonia to be effectively removed. In some embodiments, greater than 95% of the boron content and greater than 95% of the ammonia content are removed. Some method embodiments include no separate ion exchange separation step capable of removing ammonia.

摘要： Produced water from a crude oil or natural gas production process is purified using a membrane purification system for petroleum production, agricultural, commercial and domestic uses. The produced water is pretreated to remove, at least, particulates and oil from the produced water. The minimally pretreated water is then purified in a membrane purification system, that is operated at conditions such that membrane scaling is reduced or prevented. In particular, the membrane purification system is operated to maintain the turbidity of clarified water feed to the system or intermediate aqueous streams that are cascading through the membrane purification system. Ensuring that the turbidity of the reject streams generated in the membrane system are useful in achieving long membrane operating life.

摘要： Modular systems for extracting hydrocarbons from subterranean volumes and associated methods are generally described. Methods for extracting hydrocarbons from a subterranean volume are also described. Some of the described methods comprise flowing a mixture comprising hydrocarbons and water from the subterranean volume to a plurality of fluidically connected separation units and at least partially separating the hydrocarbons from the water using the separation units to produce a first stream comprising higher purity water than the mixture. In certain cases, the method includes fluidically disconnecting at least one of the separation units from the remaining separation units while the separating step is being performed. Some methods include fluidically connecting an additional separation unit to the separation unit while the separating step is being performed.

摘要： The invention relates to a method for processing sulphate-containing water. The method contains stages in which sulphate-containing water is directed to an anaerobic bioreactor, and an anaerobic bacterial strain that converts sulphate to hydrogen sulphide converts the sulphate contained in the water to hydrogen sulphide gas. The resulting hydrogen sulphide gas is directed for incineration in a hydrogen sulphide incineration unit, which produces combustion gases containing sulphur dioxide. Energy released at various stages in the process is recovered and reused in the same process. The residual water is removed from the bioreactor.

摘要： Disclosed herein is a controlled method of minimizing radioactive sludge generation in treatment of wastewater from an oil and/or gas well. The method comprises measuring a concentration of a radioactive material in wastewater to be treated and measuring a concentration of barium in the wastewater to be treated. The method further comprises adding a calculated quantity of sulfate to the wastewater to be treated sufficient to precipitate a quantity of barium sufficient to reduce the concentration of the radioactive material to a level such that sludge precipitated in a secondary precipitation has a radiation level below a defined radiation level.
