Abstract: Plants and methods are presented for crude feed pre-processing before feeding the crude feed into a crude unit or vacuum unit. Pre-processing is preferably achieved with a combination of a preflash drum and a preflash column that allows for high-temperature treatment of the liquids and separate vapor phase handling, which advantageously enables retrofitting existing plants to accommodate lighter crude feeds.

Abstract: A plant comprises a feed gas source, H2S removal unit, first absorber and a second, pressure reduction stages, first and second heat exchangers, stripping unit, and a conduit. The H2S removal unit selectively removes H2S from a feed gas from the feed gas source to produce an H2S depleted feed gas. The first absorber and the second absorber remove CO2 from the H2S depleted feed gas using a semi-lean and an ultralean solvent to produce a product gas and a rich solvent. The plurality of pressure reduction stages generates a cooled flashed solvent. The first heat exchanger and the second heat exchanger use the cooled flashed solvent to cool the H2S depleted feed gas and the semi-lean solvent. The stripping unit strips the flashed solvent with dried air to produce the ultralean solvent, and the conduit combines a portion of the ultralean solvent with the H2S depleted feed gas.

Abstract: Systems and methods for optimizing the recondensation of boiloff gas in liquid natural gas storage tanks are presented. In especially preferred aspects of the inventive subject matter, BOG from a storage tank is condensed using refrigeration content of a portion of LNG sendout in a direct or indirect manner, and the BOG condensate and LNG sendout portion are combined to form a subcooled stream that is then combined with the balance of the LNG sendout, to be fed to a high pressure pump. Contemplated recondensation operations advantageously occur without using otherwise needed large volume recondensers. Moreover, the condensing and subcooling operations are decoupled from the LNG sendout rate.

Abstract: A method for treating a flue gas that includes determining a sulfur trioxide concentration within the flue gas and determining an injection rate for a sulfur trioxide sorbent based upon the sulfur trioxide concentration. Also, a method for treating a flue gas that includes determining a sulfuric acid dew point for the flue gas and determining a coolant injection rate for a coolant to be injected into the flue gas to cause the flue gas to have a temperature of from about 20 to about 30° F. above the sulfuric acid dew point.
