Abstract: Selective recovery of C2 to C4 hydrocarbons is achieved through the use of a converging-diverging nozzle, or de Laval nozzle. The vapor stream comprising C2 to C4 hydrocarbons is fed into an inlet of a de Laval nozzle having a throat. The vapor stream may have an initial temperature of between 0° C. and 100° C., and an initial pressure of between 200 psig and 500 psig. In the de Laval nozzle, the vapor stream expands after passing through the throat of the de Laval nozzle, producing a vapor stream having reduced temperature and pressure. Then, C2 to C4 hydrocarbons condense from the reduced-temperature vapor stream as liquid droplets, which may be recovered. Fractionation of C2 to C4 hydrocarbons by means of a de Laval nozzle is possible; the technique allows selective recovery of propane from a mixture of propane and ethane.

Abstract: Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

Abstract: The invention relates to a carbon-sequestering desalination brine waste processing system comprising a carbon sequestration system and a plurality of brine removal system for a desalinization plant. The carbon sequestration system is configured to receive brine from a brine source and inject at least one of CO2 or CO into the brine to provide carbon sequestrated brine. The plurality of brine removal systems are connected in series or parallel and sequentially extract brine and water vapor from the carbon sequestrated brine. Each brine removal system includes at least one atomizing unit for spray atomization and vacuum flashing the carbon sequestrated brine into atomized water vapor and concentrated brine. Further, each subsequent brine removal system includes at least one mineral extraction unit allowing sequential removal of minerals from the concentrated brine received from a previous brine removal system, and provide minerals and stable carbon products, till substantially zero brine discharge is achieved.

Abstract: Certain implementations of amine sweetening of flash gas are described. Flash gas including acid gas is flowed from a flash drum through a column section connected to the flash drum. A lean amine stream is flowed through the column section. The lean amine stream is configured to treat the acid gas flowed from the flash drum through the column section. A quantity of the lean amine stream flowed through the column section is controlled based, in part, on a rate at which the flash gas including the acid gas is flowed from the flash drum through the column section and a concentration of the acid gas in the flash gas.
