    摘要： A continuous online process for rejuvenating whole stream of contaminated lean sulfolane in an extraction system is provided. In particular, a rejuvenator is installed in the solvent circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. Specifically, the rejuvenator comprises a high pressure vessel with a removable cover and a round rack with vertical stainless steel tubes fitted in the high pressure vessel. A magnetic bar is placed in each stainless steel tube. A screen cylinder is installed inside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up its contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is characterized by simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system can be operated at high efficiency and high capacity without the dreaded corrosion.

    摘要： Aliphatic esters, R'COOR are produced by reacting the corresponding alcohol, ROH having carbon numbers of the alkyl groups, R′ and R, between 0 and 9 and 1 and 10, respectively, with molecular oxygen in the presence of a dual functional catalyst comprising metal on acidic solid support. In particular, the process is used advantageously for production of ethyl acetate by conversion of ethanol. The reaction mixture from the reactor is separated through azeotropic distillation to recover the ethyl acetate as product and the by-product, acetaldehyde and acetic acid which could be recycled for further reaction. The process is characterized by high conversion of ethanol, high selectivity and high yield for ethyl acetate and low waste stream generation. The preferred catalyst is Pd on zeolites which is active, selective, stable and regenerable.

    摘要： Acidic halides, especially chlorides, are removed from dry process vapor and liquid hydrocarbon streams by contact with solid caustic, such as a bed of NaOH. Salt deposits from form on the solid caustic, which are periodically removed by passing a liquid hydrocarbon continuous phase containing a minor amount of dissolved or entrained water over the solid caustic. Salts may be removed from the liquid hydrocarbon by extraction with water, which also saturates the liquid hydrocarbon so that it may be used to remove additional salt deposits.

    摘要： Waste materials are removed from Stretford solution in the form of sulfates by catalytic oxidation. The Stretford solution, which was used to treat sulfur contaminated gas streams is first regenerated by oxidation to restore the vanadium present to a pentavalent form. It is then passed to a reaction zone where it is contacted with a catalyst and an oxygen source. The catalyst comprises a porous solid substrate on which a metal or metal compound insoluble in Stretford solution is deposited. Waste materials, primarily thiosulfates, are thus oxidized to sulfates. The effluent of the reaction zone is then passed to a crystallizer, where the sulfates are precipitated out as crystals of Glauber's salt. The Glauber's salt is recovered as a product and the Stretford solution is recycled to a scrubber for the treatment of gas streams.

    摘要： Wells producing oil and gas are treated with formation waters containing selected time-release scale inhibitors to reduce the deposit of scale in the wellbore and within the formation. The inhibitors are formed by cross-linking a polyacrylic acid compound of controlled molecular wright from about 1,000 to 10,000 with trivalent chromium cations to produce a water-soluble complex which progressively releases the inhibitor from the formation over an extended period of time.
