    Abstract: Process for the conversion of synthesis gas to hydrocarbons, at least a portion of which are liquid at ambient temperature and pressure, by contacting the synthesis gas at an elevated temperature and pressure with a suspension comprising a particulate Fischer-Tropsch catalyst suspended in a liquid medium, in a reactor system comprising at least one high shear mixing zone and a reactor vessel. The process comprises passing the suspension and synthesis gas through the high shear mixing zone(s) where the synthesis gas is broken down into gas bubbles and/or irregularly shaped gas voids; discharging suspension having gas bubbles and/or irregularly shaped gas voids dispersed therein from the high shear mixing zone(s) into the reactor vessel; and introducing a liquid coolant into the reactor system.

    Abstract: Inhibitors of wax deposition for crude oils are polymers of a monomer with structural units derived from at least one ester (i) of an aliphatic carboxylic acid with an aliphatic alcohol, wherein one of the acid and alcohol is ethylenically unsaturated and the other of the acid and alcohol has a long chain group of 14-40 carbons, and a monomer with structural units derived from a corresponding ester (3) with structural units derived from an aliphatic carboxylic acid and an aliphatic alcohol, wherein one of the acid and alcohol is ethylenically unsaturated and the other has an aliphatic group of 1-13 carbons, such that at least 30% preferably 50-90% of the said aliphatic groups have 15-35 carbons. They are preferably made by transesterification. Blends of such polymers and/or the corresponding homopolymers or copolymers of ester 1 and/or polyalkylene imines with long side chains, and optionally with monomeric polar additives may be used as inhibitors.

    Abstract: An integrated system includes a desalination plant including a reverse osmosis (RO) array to produce an RO permeate blending stream and a nanofiltration (NF) array to produce an NF permeate blending stream. The integrated system also includes a blending system. Further, the integrated system includes a control unit. Still further, the integrated system includes an injection system for one or more injection wells that penetrate an oil-bearing layer of a reservoir. Moreover, the integrated system includes a production facility to separate fluids produced from one or more production wells that penetrate the oil-bearing layer of the reservoir and to deliver a produced water (PW) stream to the blending system. The blending system is configured to blend the RO permeate and NF permeate blending streams with the PW stream to produce a blended low salinity water stream. The control unit is configured to dynamically alter operation of the blending system to adjust amounts of at least one of the RO permeate blending stream and the NF permeate blending stream to maintain a composition of the blended low salinity water stream within a predetermined operating envelope.
