摘要： Processes for hydrotreating an effluent from a slurry hydrocracking process are described. Different streams are formed from the SHC effluent, and different hydroprocessing conditions are applied to the streams, e.g., more severe conditions are applied to streams which need additional hydroprocessing, while less severe conditions are applied to streams which do not need as much hydroprocessing. Common equipment is shared between different hydroprocessing steps.

摘要： A family of highly charged crystalline microporous metallophosphate molecular sieves designated PST-17 has been synthesized. These metallophosphates are represented by the empirical formula of: Rp+rAm+MxEyPOz where A is an alkali metal such as potassium, R is a quaternary ammonium cation such as ethyltrimethylammonium, M is a divalent metal such as zinc and E is a trivalent framework element such as aluminum or gallium. The PST-17 family of molecular sieves are stabilized by combinations of alkali and organoammonium cations, enabling unique metalloalumino(gallo)phosphate compositions and exhibit the BPH topology. The PST-17 family of molecular sieves has catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.

摘要： This present disclosure relates to apparatuses for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, the present disclosure relates to apparatuses for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex using processed toluene instead of crude toluene.

摘要： Processes and apparatus for making xylenes and phenol are described. Phenol and alkyl phenols are separated from coal derived liquid. The phenol is separated from the alkyl phenols. The alkyl phenols can be reacted with aromatics such as benzene and toluene to make xylenes. The xylenes and other aromatics are then separated from the phenol and alkyl phenols. Para-xylene is separated and recovered using a xylene separation process, and meta-xylene and ortho-xylene are optionally converted to para-xylene through an isomerization reaction.

摘要： Processes for recovering electrical power from a process unit waste heat steam generation system are described. A power-recovery turbine reduces the pressure of a stream of superheated steam to a pressure lower than that needed by the steam reboiler for use in other process units or equipment in the plant.

摘要： A process of treating a natural gas stream is provided comprising sending natural gas stream through a first adsorbent bed to remove water and heavy hydrocarbons (C8+) to produce a partially treated gas stream in which the first adsorbent bed is regenerated by a temperature swing adsorption process and then sending the partially treated gas stream through a second adsorption bed to remove carbon dioxide and lighter hydrocarbons (C7−) to produce a purified natural gas stream wherein said second adsorption bed is regenerated by a temperature pressure swing adsorption process.

摘要： An improved isomerization process in which the inlet temperature to the isomerization reaction zone is less than 105° C. is described. A separate reactor is provided for the decomposition of the organic chloride. The product of the decomposition of the organic chloride is sent to an isomerization reactor along with a hydrocarbon feed containing paraffins. The use of the organic chloride decomposition reactor allows the operating temperatures for the isomerization reaction zone to be reduced.

摘要： A process for producing an isomerized product comprises sending a feed stream comprising butanes, hydrogen and an organic chloride to a butane isomerization reactor containing an isomerization catalyst to convert a portion of normal butanes in said feed stream to iso-butanes in an isomerized stream. The isomerized stream to a stabilizer column to produce a butane stream containing normal, iso-butanes and C5 hydrocarbons; the butane stream is sent to a column to produce an isomerized upper stream and a bottoms stream comprising a mixture of butanes, C5 hydrocarbons and organic chloride. The bottoms stream is sent to an organic chloride decomposition reactor to produce a mixture of HCl, hydrogen and hydrocarbons.

摘要： A hydroprocessing catalyst has been developed. The catalyst is a poorly crystalline transition metal tungstate material or a metal sulfide decomposition product thereof. The hydroprocessing using the crystalline ammonia transition metal tungstate material may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

摘要： A plant or refinery may include equipment such as reactors, heaters, heat exchangers, regenerators, separators, or the like. Types of heat exchangers include shell and tube, plate, plate and shell, plate fin, air cooled, wetted-surface air cooled, or the like. Operating methods may impact deterioration in equipment condition, prolong equipment life, extend production operating time, or provide other benefits. Mechanical or digital sensors may be used for monitoring equipment, and sensor data may be programmatically analyzed to identify developing problems. For example, sensors may be used in conjunction with one or more system components to detect and correct maldistribution, cross-leakage, strain, pre-leakage, thermal stresses, fouling, vibration, problems in liquid lifting, conditions that can affect air-cooled exchangers, conditions that can affect a wetted-surface air-cooled heat exchanger, or the like. An operating condition or mode may be adjusted to prolong equipment life or avoid equipment failure.
