摘要： An improved method for processing the effluent of a hydrocarbon conversion zone. The invention is particularly useful in a catalytic reforming reaction, wherein practice of the invention results in an increased recovery of butane and propane. The effluent is separated into vapor and liquid components, which are then recontacted at a higher pressure. Several recontacting steps may be employed. Liquid product is then subjected to fractionation. Overhead vapor from the fractionation zone is recycled back to a recontacting step in order to recover a portion of the hydrocarbons contained therein, instead of routing the vapor to the plant fuel gas system.

摘要： A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones, in each of which the catalyst particles are downwardly movable via gravity-flow. At least three reaction zones are utilized, with the fresh feed and hydrogen reactant stream being split between the first and second. The flow of that portion introduced into the second zone is restricted. Effluent flow from the first reaction zone is also restricted and combined with the effluent from the second reaction zone; the mixture is introduced into a third reaction zone. Where the catalytic conversion system consists of four reaction zones, the flow of effluent from the third is restricted prior to the introduction thereof into the fourth reaction zone. This technique decreases the mass flow to the first two zones and increases the pressure drop experienced within the entire conversion system, thus serving to alleviate the problems associated with the occurrence of stagnant catalyst areas as a result of catalyst particles being "pinned" within the reaction zone and thus unable to assume a downward, gravity-flow pattern. Restriction of the second zone feed and first reaction zone effluent insures a higher pressure in the first zone.

摘要： Disclosed are heaters having at least one adjustable fired burner and an adjustable fired burner for use with various types of heaters. The heaters may be part of an industrial processes such as petroleum refining. The adjustable burners are configured to be adjusted and positioned in any direction and then be locked into place. The adjustable burners may be adjusted automatically or manually. The ability to quickly adjust the position of an adjustable burner results in substantially less or virtually no damage to elements in the heater and provides for a more even distribution of heat within the heater.
