    摘要: A combination of an etherification process and a process for the isomerization of linear alkenes to isoalkenes uses an adsorptive separation zone that receives an effluent fraction from the etherification reaction zone and separates the fraction at low efficiency to produce an isomerization feed stream comprising normal butenes and butanes, and a butane stream that is rejected from the process. The rejection of butanes at low efficiency reduces or eliminates the loss of butenes with the rejection of butane. A low efficiency adsorptive separation to reject butanes also benefits the isomerization process by inhibiting coking.

    摘要: An apparatus for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with apertures disposed within the partitions. The apertures are covered by louvers that extend above the edges of the apertures to prevent solid particles from spilling through inlet apertures.

    摘要: A channel reactor arrangement and a process that uses a high heat capacity heat exchange liquid to indirectly heat or cool by indirect heat exchange. The channel reactor arrangement maintains a pressure gradient through the channels and a pressure differential between the reaction channels and the heat exchange channels at all points to preserve the integrity of the plates defining the channels and to prevent any leakage of high heat capacity liquids into the reaction channels. The system brings the efficiency of plate reactor arrangements to the effectiveness of high heat capacity heat exchange fluids such as molten salts and liquid metals. The process overcomes the problem of low heat exchange pressure drop in combination with high reactant pressure drop by creating a negative pressure differential from reactant channels to the heat exchange channels. Proper control of the pressure drop maintains a positive pressure differential at all locations between the reactant channels and heat exchange channels to prevent any backflow of the heat exchange fluid into the reactant channels while maintaining the overall pressure differential between the channels within suitable limits for plate reactor arrangements. Highly exothermic processes such as oxidation reactions or endothermic processes such as dehydrogenation achieve the most benefit from this invention.

    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.
