Abstract: Disclosed herein are systems and processes for removing heavies during the liquefaction of a natural gas. The processes include dissolving the heavies in the natural gas by adding external natural gas liquid (NGL), followed by a staged removal of the natural gas liquid (NGL) and dissolved heavies.

Abstract: In a process for the combined production of a) a hydrogen-enriched gas and a carbon monoxide-enriched gas and/or b) a mixture of hydrogen and carbon monoxide by cryogenic distillation and scrubbing, a still liquor is extracted from a scrubbing column and sent to a stripping column, a still liquor is extracted from the stripping column and sent to a separating column for carbon monoxide and methane and a cooling fluid is used at a pressure greater than that of the head of the separating column for cooling at least one fluid extracted at an intermediate level from the scrubbing column.

Abstract: Method and system for removing high freeze point components from natural gas. Feed gas is cooled in a heat exchanger and separated into a first vapor portion and a first liquid portion. The first liquid portion is reheated using the heat exchanger and separated into a high freeze point components stream and a non-freezing components stream. A portion of the non-freezing components stream may be at least partially liquefied and received by an absorber tower. The first vapor portion may be cooled and received by the absorber tower. An overhead vapor product which is substantially free of high freeze point freeze components and a bottoms product liquid stream including freeze components and non-freeze components are produced using the absorber tower.

Abstract: Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent to form a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is compressed, partially condensed and cooled to form a partially condensed, compressed net gas phase stream. The partially condensed, compressed net gas phase stream is separated to form an intermediate gas phase stream. The intermediate gas phase stream is cooled to form a cooled intermediate gas phase stream. The liquid phase hydrocarbon stream is cooled to form a cooled liquid phase hydrocarbon stream. The cooled intermediate gas phase stream is contacted with the cooled liquid phase hydrocarbon stream to form an H2-rich stream and a cooled second intermediate liquid phase hydrocarbon stream that is enriched with C3/C4 hydrocarbons.

Abstract: A mixed phase unstabilized hydrocarbon stream is created by partially evaporating an unstabilized hydrocarbon condensate stream, including indirectly heat exchanging the unstabilized hydrocarbon condensate stream against an effluent stream in a feed-effluent heat exchanger. The mixed phase unstabilized hydrocarbon stream is fed into a stabilizer column. A liquid phase of stabilized hydrocarbon condensate is discharged from a bottom end, while an overhead vapour stream consisting of a vapour phase comprising volatile components from the unstabilized hydrocarbon condensate stream is discharged from a top end of the stabilizer column. The overhead vapour stream is passed through an overhead condenser. The resulting partially condensed overhead stream is separated in an overhead separator into a vapour effluent stream and an overhead liquid stream. The effluent stream against which the unstabilized hydrocarbon condensate stream is heat exchanged in the feed-effluent heat exchanger comprises the vapour effluent stream.
