A combined vessel comprises a stripping section for removing acid gases from a sour water stream and a direct contact heat exchanger section for heating a graywater stream in order to improve heat and mass transfer in the treatment and recycle of water streams for a gasification process.

A stirrer is provided that can more efficiently achieve shearing applied, by an action of an intermittent jet flow, to a fluid to be processed. The stirrer concentrically includes a rotor including a blade, a partition wall, and a screen, wherein: the screen includes a plurality of slits in a circumferential direction thereof and screen members located between the adjacent slit; by rotating at least the rotor of the two components, the fluid to be processed is discharged from the inside to the outside of the screen as the intermittent jet flow through the slit of the screen; the screen has a cylindrical shape having a circular cross section; an opening of the slit provided on the inner wall surface of the screen is used as an inflow opening; openings of the plurality of slits provided on the outer wall surface of the screen are used as outflow openings; and the width of the outflow openings in the circumferential direction is set to be smaller than the width of the inflow opening in the circumferential direction.

A system for stabilizing a hydrocarbon feedstock includes a High Pressure Separation (HPS) unit in fluid communication with a feedstock inlet. The HPS unit includes an oil outlet. The system includes a heated Low Pressure (LP) separator unit downstream from and in fluid communication with the oil outlet of the HPS unit. The heated LP separator unit includes an oil outlet.

A method for recovering a distillable, anhydrous methane-sulfonic acid (MSA) liquid phase from an anhydrous 2-phase gas-liquid mixture wherein the anhydrous 2-phase gas-liquid mixture is generated by sulfonating methane (CH.sub.4) with sulfur trioxide (SO.sub.3) in an MSA-forming reactor, or reactor system, according to a radical chain reaction wherein the method comprises (i) separating the gas phase from the liquid phase, (ii) passing the separated liquid phase into a stripping column, and (iii) recovering the stripped anhydrous liquid phase.

The degassing device includes a degassing flow path, a vacuum chamber, a vacuum pump, an inlet flow path, an outlet flow path, a drain flow path, a downstream side switching unit, and a controller. The degassing flow path is made of a gas-permeable, liquid-impermeable tube, and is accommodated in the vacuum chamber. The inlet flow path is for introducing a mobile phase to the degassing flow path, and the outlet flow path is for causing a mobile phase which has passed through the degassing flow path to flow out. The drain flow path is provided separately from the outlet flow path and is configured to drain the mobile phase in the degassing flow path from the degassing flow path. The downstream side switching unit is configured to switch the downstream end of the degassing flow path so as to be connected to either the outlet flow path or the drain flow path. The controller controls the operation of the downstream side switching unit, and is configured to connect the downstream end of the degassing flow path to the drain flow path at a predetermined timing when feeding of the mobile phase by the liquid feeding pump is stopped to drain the mobile phase in the degassing flow path through the drain flow path.
