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.

An active rotating separator is disclosed, comprising a separator drum arranged to receive multiphase fluid via an upstream end and to deliver separated fluid phases from a downstream end of the drum. An electric motor is installed in the flow through the drum, the motor operable to generate rotation in the fluid flow that passes through the drum, the motor comprising an open rotor permitting through-flow of fluid through the motor.

A cyclone type liquid/gas or liquid/liquid separator having separation properties that are stabilized, even when the flow rate and the proportions of the liquid phases for separation vary, by means of a platform situated in the low portion of a cylindrical separation chamber that is fed at its top end via a tangential feed orifice. An installation and a method are also provided for separating the oil and water contained in crude oil, with the help of a cyclone separator.

A cyclonic separator is provided, comprising at least one cyclonic chamber in the form of a cylindrical tube, having an upper inlet end and a lower liquid outlet end, at least one involute chamber located adjacent to and in fluid communication with the upper end of each of the at least one cyclonic chambers. The involute chamber comprises an involute inlet and a gas outlet proximal an upper end of the involute chamber. An inlet manifold is in fluid communication with said at least one involute chamber via the involute inlet. Said involute inlet of said involute chamber is laterally separated from said gas outlet. A method is further provided for separation of a mixed heavy phase/light phase process stream.

A hydraulic fluid tank arrangement for a working machine is provided, the arrangement including a hydraulic fluid tank; an inlet portion for receiving hydraulic fluid into the hydraulic fluid tank; and an oil filter arranged in fluid communication with the inlet portion; wherein the hydraulic fluid tank arrangement further includes a gas removal device arranged in fluid communication with the oil filter downstream the inlet portion and upstream the oil filter for removing gas from the hydraulic fluid before the hydraulic fluid reaches the oil filter. A method for removing gas from hydraulic fluid contained in a hydraulic fluid tank arrangement is also provided.

An air-oil separation system for a gas turbine engine system comprises a housing that extends circumferentially around an axis to define an interior chamber of the housing and a separation unit located in the chamber. The housing is formed to include an inlet configured to receive a mixture of air and oil, an oil outlet configured to conduct oil to exit the housing, and an air outlet configured to conduct air to exit the housing. The air-oil separation unit separates air from the oil.

A hydraulic fluid de-aeration device for a hydraulically actuated variable valve actuation system is provided. The device includes a de-aeration bridge having a first end and a second end. The device includes a conical de-aeration chamber having an outer wall and a generally vertical center axis. The second end of the de-aeration bridge is offset from the center axis of the de-aeration chamber such that hydraulic fluid flowing from the de-aeration bridge is directed towards the outer wall of the de-aeration chamber. The device includes a cover with a vent hole for air that is expelled from the hydraulic fluid. A passage connected to the de-aeration chamber supplies the hydraulic fluid to a hydraulic fluid gallery of the variable valve actuation system.

A hydraulic fluid de-aeration device for a hydraulically actuated variable valve actuation system is provided. The device includes a bridge and a de-aeration chamber having an upper chamber, a lower chamber, and a central axis. A vent pipe is arranged along the central axis of the de-aeration chamber and can include at least one vent hole. The bridge is arranged such that hydraulic fluid flowing from the bridge is directed towards an outer wall of a top portion of the lower chamber. The device includes a cover that integrates the upper chamber with a vent hole for air that is expelled from the hydraulic fluid. An optional gasket or plate configured with at least one vent hole can be arranged between the upper and lower chamber. The vent pipe can be arranged within the cover and extend through the upper chamber to the lower chamber.

An apparatus for separating hydrocarbons from water, comprising a tank segment with a fluid inlet subsequent a housing with a liquid gas mixer. The fluid inlet through a cylindrical tank wall,and further through the wall of a conical wall segment, a pipe spread, combining radial and axial flow over ring mounted guide vanes at the upper part of the conical wall segment. A hydro carbon outlet is located at a top end and a water outlet at a bottom end of tank-segment. A pipe for scale and debris removal is connected to the lower part of the bowl. The inner conical wall segment extends to the top end of the tank segment and at this location comprises a ring of vertically mounted guide vanes.
