Provided is a gas processing facility capable of enhancing the performance of an air-cooled heat exchanger while suppressing the influence on apparatus from spraying of demineralized water to the air-cooled heat exchanger to be used in a processing of natural gas. An air-cooled heat exchanger arranged in the gas processing facility for performing a liquefaction process of natural gas and the like is configured to supply cooling air to a tube through which a fluid to be cooled is caused to flow, to thereby cool the fluid to be cooled, and a mist supply section is configured to supply mist obtained by spraying demineralized water, to thereby cool the cooling air. Further, the mist supply section is configured to spray the demineralized water from a lateral position on an upstream side of an intake.

The present invention discloses a homogenous cerium (Ce) catalyst composition comprising Ce(IV) complex alone, or Ce(IV) complex in a mixture with Ce(III) complex, that can significantly improve both LPG and soot combustion, resulting in higher flame temperatures, faster heating, reduced cooking time and reduced fuel consumption. The cerium(III) complex is cerium(III) 2-ethylhexanoate and the cerium(IV) complex is aqua(2-N-(2-hydroxyethylimino)-4-pentanoate) dinitrocerium(IV) [Ce(L1)(H.sub.2O)(NO.sub.3).sub.2], wherein L1 is 2-N-(2-hydroxyethylimino)-4-pentanone.

A flare recovery method includes receiving a flare gas inlet stream that has C.sub.1-C.sub.8 hydrocarbons. The flare gas inlet stream is separated in a recovery column to produce a C.sub.1-C.sub.2 hydrocarbon stream and a C.sub.3-C.sub.8 hydrocarbon stream. The C.sub.3-C.sub.8 hydrocarbon stream is separated in a separation column to produce a C.sub.3 hydrocarbon stream and a C.sub.4-C.sub.8 hydrocarbon stream. The C.sub.4-C.sub.8 hydrocarbon stream is transported to a location for blending with crude oil. The C.sub.3 hydrocarbon stream is optionally recovered as a saleable product or is combined with the C.sub.1-C.sub.2 hydrocarbon stream to produce a flare gas stream.

A portable pressure swing adsorption method and system for low flow rate gas processing. A method of processing of hydrocarbon gas includes feeding hydrocarbon gas through a first adsorption bed of a pressure swing adsorption system, recovering light product from the first adsorption bed during the feed time, obtaining heavy product from a second adsorption bed during the feed time, wherein the second adsorption bed depressurizes to about vacuum during the feed time, compressing the heavy product to obtain natural gas liquid and vapor, sending a volume of reflux gas through the first adsorption bed after the feed time to obtain additional light product, and adjusting the feed flowrate, the feed time, or the volume of reflux gas based on a gross heating value of the feed gas, wherein adjusting the volume of reflux gas includes combining NGL storage tank vapor with the reflux gas.

The present invention describes a process for the isomerization of a light naphtha with a view to forming high octane number gasolines, said process using a deisopentanizer and a deisohexanizer which are thermally integrated in a manner such as to reduce the consumption of the high temperature utilities employed in the process.
