    摘要： A process has been developed for producing fuel from renewable feedstocks such as plant and animal oils and greases. The process involves treating a first portion of a renewable feedstock by hydrogenating and deoxygenating in a first reaction zone and a second portion of a renewable feedstock by hydrogenating and deoxygenating in a second reaction zone to provide a diesel boiling point range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the first reaction zone to increase the hydrogen solubility of the reaction mixture.

    摘要： A process to separate diisopropyl ether from a mixture of diisopropyl ether, isopropyl alcohol, and water has been developed. The process begins with distilling, in a distillation column, the mixture into a bottoms stream containing water and isopropyl alcohol and an overhead stream containing an azeotrope of diisopropyl ether, isopropyl alcohol, and water. The overhead stream is condensed and allowed to form an aqueous phase enriched in isopropyl alcohol and water and an organic phase enriched in diisopropyl ether with some water and isopropyl alcohol in an overhead receiver. The aqueous phase is recycled to the distillation column. The organic phase is passed to a drier to form a bottoms product stream containing at least 99 mole percent diisopropyl ether and a drier overhead stream containing an azeotrope of diisopropyl ether, isopropyl alcohol, and water. The drier overhead stream is condensed and introduced to the overhead receiver described earlier to combine with the condensed overhead stream from the distillation column and to form the aqueous phase and an organic phase discussed above. The bottoms diisopropyl ether product stream from the drier is collected.

    摘要： A process for regenerating solid treating particles contained in at least two vessels of a swing bed regeneration operation where the effluent of the regeneration operation is maintained regeneration fluid-free and at a substantially constant flowrate has been developed. The swing bed regeneration operation involves an on-line vessel treating process fluid and an off-line vessel for regeneration. At least a portion of the process fluid effluent from the vessel on-line is conducted to a displacement surge drum. The flowrate of the process fluid effluent from the displacement surge drum is controlled so that downstream units receive a substantially constant flowrate. A portion of the process fluid effluent from the displacement surge drum is periodically used to displace regeneration fluid from the vessel off-line, and during the displacement, the flowrate of effluent from the displacement surge drum is increased to provide additional flow to the vessel off-line without having to reduce the flow to downstream units.

    摘要： Processes for the production of ethers from alcohols and isoolefins are disclosed. Isoolefins having four to five carbon atoms per molecule are combined with a monohydroxy alcohol having from one to five carbon atoms per molecule and with a recycle stream comprising alcohol and water to form an etherification zone feed stream which is passed through an etherification zone to produce the desired ether. The effluent from the etherification zone is separated into an ether product and an aqueous product containing unreacted alcohol which is recycled to provide a portion of the etherification zone feed stream. Distillation can be employed to separate the effluent from the etherification zone into a bottoms product stream, comprising the ether, a distillate product comprising other hydrocarbons and the above-mentioned recycle stream. When producing ethyl-tertiary-butyl ether (ETBE), azeotropic grade ethanol, i.e., about 5 vol. % water, is preferably utilized. The utilization of the alcohol/water recycle stream can obviate the need for additional alcohol recovery from the distillate product.
