A natural gas liquid plant is retrofitted with a bolt-on unit that includes an absorber that is coupled to an existing demethanizer by refrigeration produced at least in part by compression and expansion of the residue gas, wherein ethane recovery can be increased to at least 99% and propane recovery is at least 99%, and where a lower ethane recovery of 96% is required, the bolt-on unit does not require the absorber, which could be optimum solution for revamping an existing facility. Contemplated configurations are especially advantageous to be used as bolt-on upgrades to existing plants.

A remote hydrocarbon processing system comprising a gas compressor skid, gas processing skid, electric power generation skid, liquid storage tank, blending skid, and crude oil source, are fluid flow interconnected and located proximate to a producing well. Produced gases are delivered from the well to the gas compressor skid. Compressed natural gas is delivered to the gas processing skid where it is thermally separated to generate a processed gas stream and a processed liquid stream. The processed gas stream is delivered to the electric power generation skid and burned to generate electricity that may be delivered to an electric power transmission line. The processed liquid stream is delivered to the liquid storage tank. Crude oil from the crude oil source and processed liquid stream from the liquid storage tank are delivered to the Blending skid and blended into a lower viscosity, higher API gravity transportable crude oil.

An integrated refinery process for removing mercaptans from a hydrocarbon stream containing mercaptans and converting by-product disulfide oil to useful products. The process includes introducing the hydrocarbon stream containing mercaptans into an extraction vessel containing an alkaline solution and passing the hydrocarbon stream through an extraction section of the extraction vessel which includes one or more liquid-liquid contacting decks for reaction to convert the mercaptans to alkali metal alkanethiolates. Further, the process includes withdrawing a hydrocarbon product stream free of mercaptans from the extraction vessel and recovering spent caustic containing alkali metal alkanethiolates from the extraction vessel. Additionally, the process includes subjecting the spent caustic containing alkali metal alkanethiolates to air oxidation to produce a by-product stream containing disulfide oils (DSO) and sulfides and processing the by-product stream in a steam cracking unit to produce a DSO free product stream.

Integrated systems are provided for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compositions, from methane using an oxidative coupling of methane system to convert methane to ethylene, followed by conversion of ethylene to selectable higher hydrocarbon products. Integrated systems and processes are provided that process methane through to these higher hydrocarbon products.

The invention relates to various nonlimiting embodiments that include methods, apparatuses or systems for processing natural gas comprising a heavies removal column processing natural gas and light oil reflux. The overhead stream goes to heavies treated natural gas storage. The heavies removal column reboiler bottoms stream product is input to a debutanizer column. The debutanizer column overhead lights are input to a flash drum where the bottoms is pumped through a heat exchanger as a light oil reflux input to the heavies removal column, while the debutanizer reboiler bottoms product is stored as stabilized condensate. Alternatively, debutanizer column overhead lights are sent to heavies treated gas storage and the bottoms stream product goes to a depentanizer column, the overhead lights are pumped through a heat exchanger as a light oil reflux input to the heavies removal column, while the depentanizer reboiler bottoms product is stabilized condensate.

The present disclosure refers to systems and methods for efficiently converting a C.sub.1-C.sub.3 alkane such as natural gas to a liquid C.sub.2-C.sub.10 product and hydrogen. Generally, the process comprises flowing the C.sub.1-C.sub.3 alkane through a plurality of tubes within a vessel wherein the tubes house a catalyst for converting the C.sub.1-C.sub.3 alkane to the liquid C.sub.2-C.sub.10 product and hydrogen. The C.sub.1-C.sub.3 alkane is heated under suitable conditions to produce the liquid C.sub.2-C.sub.10 product and hydrogen. Advantageously, the C.sub.1-C.sub.3 alkane is heated by burning a fuel outside the tubes in fuel burning nozzles configured to transfer heat from the burning through the tubes.
