The flow control device further comprises an internal flow control body having a collar positioned within the cylindrical body about the primary axis. A plurality of outer helical fins extend outwardly from the collar and define a plurality of outer helical passageways, and a plurality of inner helical fins are positioned inwardly from the collar and define a plurality of inner helical passageways.

A gas-liquid separation device comprises: an outer housing extending vertically, which is provided with a gas outlet at an upper end of the outer housing and a liquid outlet at a lower end of the outer housing; an inner housing disposed in the outer housing and extending vertically, an upper end of the inner housing being coupled to the outer housing in a sealed manner, a lower end of the inner housing being opened, with an annular space formed between the outer housing and the inner housing; a feeding tube inserted into the outer housing and communicated with the inner housing, with a cyclone mechanism between the feeding tube and the inner housing to output fluid into the inner housing as a swirling flow. The present disclosure can reduce the disturbance of the downward gas flow and the upward gas flow in the separation space, thus improving the separation efficiency.

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.

A fluid separation apparatus for removing one fluid component from another fluid component in a fluid stream includes an impeller disposed between an annular inlet chamber and a first fluid chamber having a hollow, conical trapezoidal shape with a diameter that reduces along a portion of the length of the first fluid chamber. The impeller redirects a liquid flowing in a circular swirling flow path along the wall of the inlet chamber to an outlet an inlet of the first fluid chamber disposed adjacent the central axis of the first fluid chamber. A coaxially aligned extraction pipe extends into a lighter density fluid envelope formed in the first fluid chamber adjacent the inlet of the first fluid chamber. The extraction pipe may be dynamically adjustable based on the shape of the lighter density fluid envelope to maximize removal of lighter density fluid from the lighter density fluid envelope.

The invention relates to a continuously operating process for producing nitrobenzene, comprising the following steps: a) nitriding benzene in adiabatic conditions with sulfuric acid and nitric acid, using a stoichiometric excess of benzene in relation to the nitric acid; b) first separating a gaseous phase containing benzene and gaseous secondary components from the raw process product of the nitridation in a gas separator provided specifically for this purpose, then separating, in a downstream phase-separating apparatus, the resulting liquid phase, which is depleted in gaseous components and contains nitrobenzene and sulfuric acid, into a sulfuric acid phase and a nitrobenzene phase; and c) processing the nitrobenzene phase, obtaining nitrobenzene. The invention also relates to a production plant suitable for carrying out the claimed process.

The device for pumping products from a pumping area (2) to an enclosure (3) comprises two tanks, a transfer system (8) which generates a suction of the products from the pumping area (2) to the tanks (4A, 4B) and a transfer of the non-gaseous products from the tanks (4A, 4B) to the enclosure (3), valves (3A, 3B, 3D, 3D, 3I, 4C, 4D, 4I, 4J) to, alternately, allow or block the communication from one tank (4A, 4B) to the pumping area (2) and a communication from the other tank (4A, 4B) to the enclosure (3), and a control system (25). The transfer system (8) comprises a suction unit (13) provided with hydro-ejectors (13A, 13B) connected to each tank (4A, 4B) and generating the suction of the products and a transfer unit (20) provided with a pump connected to the tanks (4A, 4B) to transfer non-gaseous products to the enclosure (3).

A gas-liquid separation device includes a cylinder, an external port, an adapter, and a gas-liquid separation component. The cylinder has a first cavity, a second cavity, and a third cavity. The external port includes a first port, a second port, and a third port. The adapter is at least partially disposed in the cylinder. The gas-liquid separation component is located in the third cavity. When the gas-liquid separation device is in a first working state, the adapter separates the third port from the third cavity, the first port serves as the inlet, and the second port serves as the outlet when the gas-liquid separation device is in a second working state, the adapter communicates the third port with the third cavity, the second port serves as an inlet, and the first port and the third port serve as outlets. The gas-liquid separation component separates gas-liquid two-phase refrigerant.

A method of separating a flow of multi-phase fluid includes directing the flow through the inlet opening of an enclosed tubular body comprising a tubular sidewall with opposed end walls, one or more axial outlet apertures formed through the end walls, and one or more radial outlet apertures formed through the tubular sidewall at locations spaced from the inlet opening. The method also includes directing the flow of multi-phase fluid onto one or more swirl plates positioned between the inlet opening and the outlet apertures, with the swirl plates having angled surfaces configured to impart a cyclonic motion to the flow so as to initiate separation of the constituents of the multi-phase. The method further includes directing the gas constituent axially outward through the axial outlet aperture and directing the oil constituent and the water constituent radially outward from the tubular body through the one or more radial outlet apertures.
