    摘要: Oxygen is separated from air by a high temperature ion transport membrane which is integrated with a gas turbine system for energy recovery from the membrane nonpermeate stream. Air is compressed, heated in a first heating step, and passed through the feed side of a mixed conductor membrane zone to produce a high purity oxygen product on the permeate side of the membrane zone. Nonpermeate gas from the membrane zone is heated in a second heating step and passed through a hot gas turbine for power recovery. The operating temperatures of the membrane zone and the expansion turbine are independently maintained by controlling the rate of heat addition in the first and second heating steps, whereby the membrane zone and expansion turbine are thermally delinked for maximum oxygen recovery efficiency.

    摘要: A convective heater for heating fluids such as a coal slurry is constructed of a tube circuit arrangement which obtains an optimum temperature distribution to give a relatively constant slurry film temperature. The heater is constructed to divide the heating gas flow into two equal paths and the tube circuit for the slurry is arranged to provide a mixed flow configuration whereby the slurry passes through the two heating gas paths in successive co-current, counter-current and co-current flow relative to the heating gas flow. This arrangement permits the utilization of minimum surface area for a given maximum film temperature of the slurry consistent with the prevention of coke formation.

    摘要: Oxygen is separated from air by a high temperature ion transport membrane which is integrated with a gas turbine system for energy recovery from the membrane nonpermeate stream. Air is compressed, heated in a first heating step, and passed through the feed side of a mixed conductor membrane zone to produce a high purity oxygen product on the permeate side of the membrane zone. Nonpermeate gas from the membrane zone is heated in a second heating step and passed through a hot gas turbine for power recovery. Water is added to the nonpermeate gas prior to the hot gas turbine to increase mass flow to the turbine and thus balance the mass flows of the air feed compressor and the expansion turbine. The operating temperatures of the membrane zone and the expansion turbine are independently maintained by controlling the rate of heat addition in the first and second heating steps and by controlling the rate of water addition, whereby the membrane zone and expansion turbine are thermally delinked for maximum oxygen recovery efficiency.

    摘要: The present invention is directed to a heat exchanger for reboiler or condenser service in a cryogenic distillation column (e.g. air separation) or other service in which small temperature differences between clean fluids are a primary objective. The exchanger comprises a stack of corrugated sheets having corrugations generally parallel to the diagonal between opposite corners of a sheet assembled with each sheet on an opposed diagonal to that of its neighbor, which provides for alternating condensing and boiling passages. These passages because of their configuration have increased primary heat transfer surfaces resulting in reduced temperature differences in the exchanger. Special edge configurations control boiling and condensing fluid flow patterns to maximize the heat transfer performance. Optionally, the heat exchanger can have an enhanced boiling surface applied to the boiling channel surface.

    摘要: There is described an improved SRC reactor quench system using a condensed product which is recycled to the reactor and provides cooling by evaporation. In the process, the second and subsequent reactors of a series of reactors are cooled by the addition of a light oil fraction which provides cooling by evaporation in the reactor. The vaporized quench liquid is recondensed from the reactor outlet vapor stream.

    摘要: A distillation method and column in which a gaseous mixture is introduced into a bottom region of a packed column having a plurality packed beds using structured packing. The gaseous mixture comprises higher and lower volatility components. The packed column is operated so that the higher and lower volatility components have a relative volatility within the column in a range of between 1.05 and 1.8. In order to alleviate the effect of liquid maldistribution in the lowermost bed of such a column, the lowermost bed is sized to be between about 50% and about 80% of the height of the next overlying bed, with 80% being preferred and the total height of the packing within the column is at least about six meters.
