    摘要： A process for recovering heat from a high pressure stream during hydroprocessing, where one embodiment of the process includes serially introducing a high pressure stream from a hot separator into a first steam generator and a second steam generator; using the first steam generator to generate a medium pressure stream of steam, and then using the medium pressure stream as stripping steam. The process also includes using the second steam generator to generate a low pressure stream of steam, and then using the low pressure stream as stripping steam.

    摘要： A hydrotreating reactor including a vessel comprising an upper zone, and intermediate zone and a lower zone. The upper zone comprises at least one upper catalyst bed. The intermediate zone comprises a vapor/liquid separation zone, wherein gas separated within the vapor/liquid separation zone is directed to a high pressure knockout drum and the liquid separated within the vapor/liquid separation zone is directed to a stripping section and then the lower zone. The lower zone comprises at least one lower catalyst bed. Preferably, the stripping section is configured and arranged for removing hydrogen sulfide and ammonia from the gas.

    摘要： The present invention discloses high selectivity copolyimide membranes for gas, vapor, and liquid separations. Gas permeation tests on these copolyimide membranes demonstrated that they not only showed high selectivity for CO2/CH4 separation, but also showed extremely high selectivities for H2/CH4 and He/CH4 separations. These copolyimide membranes can be used for a wide range of gas, vapor, and liquid separations such as separations of CO2/CH4, He/CH4, CO2/N2, olefin/paraffin separations (e.g. propylene/propane separation), H2/CH4, He/CH4, O2/N2, iso/normal paraffins, polar molecules such as H2O, H2S, and NH3 mixtures with CH4, N2, H2. The high selectivity copolyimide membranes have UV cross-linkable sulfonyl functional groups and can be used for the preparation of UV cross-linked high selectivity copolyimide membranes with enhanced selectivities. The invention also includes blend polymer membranes comprising the high selectivity copolyimide and polyethersulfone. The blend polymer membranes comprising the high selectivity copolyimide and polyethersulfone can be further UV cross-linked under UV radiation.
