A distillation and dehydration system is provided that produces an anhydrous organic solvent. The provided system includes vapor recompression (e.g., a mechanical or thermal vapor recompression unit) to recover heat from a rectification-distillation section (e.g., a rectifier/stripper column). The addition of vapor recompression enables further heat recovery within a stream by increasing the condensation temperature and pressure of that stream and later using its latent heat by condensing it.

A process is presented for the removal or aromatics from a hydrocarbon stream. The hydrocarbon stream is generated by a dehydrogenation process that generates aromatics. The process includes a two contact cooler system with the first and second contact coolers using different coolants. The second coolant is a non-aromatic hydrocarbon coolant that will absorb aromatics.

Optimized, heat-integrated methods and systems are provided to produce multiple, high-value products from oil shale, while minimizing overall energy and water usage. A method for producing multiple products from oil shale comprises: feeding raw oil shale into a heated retorting unit, to convert kerogen into a retorted stream; introducing the retorted stream to a distillation column to generate a high-cetane diesel stream, an -olefin-containing chemical stream, an asphalt/asphalt additive stream, and an overhead gas stream, wherein heat contained in the retorted stream is harnessed as distillation energy; separating the overhead gas stream into a fuel gas stream and a purge gas stream; combusting the fuel gas stream to generate hot flue gas; heating the purge gas with hot flue gas; feeding the heated purge gas directly to the heated retorting unit; and recovering the high-cetane diesel stream, the -olefin-containing chemical stream, and the asphalt/asphalt additive stream as products.

A multi-effects desalination system includes a plurality of vessels, including a first vessel, a second vessel, a third vessel, a fourth vessel, and a fifth vessel. Each vessel includes a plurality of heat tubes, a sprayer, and a housing including a preheater tube bundle. Each sprayer can be disposed above a respective plurality of heat tubes in each vessel for discharging saline water onto the plurality of heat tubes. A first tube connects a compressor unit with the first vessel. A second tube extends between a saline water source and a plurality of sprayers. Each vessel is configured to accommodate a different effect or stage of desalination occurring in the system. The housing can be configured for collecting fresh water. The fresh water collected in each housing can be transferred by the third tube to a fresh water tank.

Systems and processes for heat recovery associated with the separation of hydrocarbon components. Two compressors are used to compress a portion of an overhead vapor stream from a fractionation column. A pressure of the liquid portion of the compressed overhead is reduced and used to recover heat from an overhead of another separation zone having a fractionation column. Once the heat has been recovered the stream is recompressed. The recovered heat may be removed from the recompressed stream in a reboiler of another fractionation column. The fractionation columns may comprise a deethanizer stripper, propane-propylene splitter, and a depropanizer column.

A plant for dealcoholising alcoholic beverages includes a rectification column having at least one inlet for the alcoholic beverage, a sump and a top. The rectification column is operable such that dealcoholised beverage can be removed from the sump and exhaust vapour can be removed from the top. At least one evaporator is configured to supply the rectification column with vapour. A condenser arrangement condenses the exhaust vapour removed from the top of the rectification column, at least in part. The plant further includes a heat pump which can operate the evaporator as well as the condenser arrangement. A method for dealcoholising alcoholic beverages in a rectification column is also disclosed.

A vapor compression distillation urine processor assembly including a pump, a first phase separating apparatus, a compressor, and a second phase separating apparatus. Further detailed is a method of processing urine using a vapor compression distillation urine processor assembly.
