Embodiments of the disclosure provide an aqueous reforming system and a method for upgrading heavy hydrocarbons. A hydrocarbon feed and a surfactant stream are combined to produce a first precursor stream. The first precursor stream and an alkali feed are combined to produce a second precursor stream. The second precursor stream and a transition metal feed are combined to produce a catalytic emulsion stream. The catalytic emulsion stream is heated to produce a catalytic suspension and a decomposition gas, where the decomposition gas is separated by a first separator. The catalytic suspension is combined with a preheated water stream to produce an aqueous reformer feed. The aqueous reformer feed is introduced to an aqueous reformer such that the heavy hydrocarbons undergo conversion reactions to produce an effluent stream. The effluent stream is introduced to a second separator to produce a heavy stream and a light stream. The light stream is introduced to a third separator to produce a gas stream, a distillate stream, and a spent water stream. Optionally, a portion of the distillate stream and the hydrocarbon feed can be combined to produce the first precursor stream such that the first precursor stream is in the absence of a surfactant.

A method of recycling gaseous hydrocarbons includes flowing a hydrocarbon gas composition from a secondary separator into a compressor unit to form a compressed mixture. The secondary separator includes a crude liquid hydrocarbon input stream from a primary separator. The method includes flowing the compressed mixture into a cooling unit to cool the compressed mixture, to form a cooled composition comprising liquid hydrocarbons. The method includes flowing the liquid hydrocarbons from the cooled composition into the primary separator.

The present invention relates to a sequential thermo-chemical treatment along with adsorption-based pre-treatment process for residual oils having a very high naphthenic acid content. First stage of the process is a thermal pre-treatment step which results into generation of hydrocarbon stream with a reduced naphthenic acid content due to high temperature. In second stage of pre-treatment, generated hydrocarbon stream from stage-1 is subjected to esterification reaction with alcohol, such as methanol, to further reduce the TAN of hydrocarbon stream. After recovery of alcohol from the reaction mixture, depending on TAN reduction required reaction mixture may be subjected to an adsorption stage, third stage pre-treatment, where an adsorbent mixture comprising of FCC spent catalyst is used to adsorb the TAN of feed hydrocarbon stream. The treated hydrocarbon stream is then co-processed with DCU feed stock for producing lighter hydrocarbons.

A system for processing oil and gas at an offshore facility includes a single stage separation module. A gas stream from the single stage separation module is pressurized in a primary compressor, and then is used to heat the incoming oil and gas upstream of the single stage separation module. Flash gas from treatment of an oil stream from the single stage separation module is pressurized in a flash gas compressor and then is used to heat glycol utilized in a gas dehydration unit. The pressurized flash gas is then commingled with the gas stream from the single stage separation module upstream of the primary compressor.
