A system and a method for monitoring and regulating the level of contents in a vessel is disclosed. In some embodiments, the system or the method use laser beams and photosensors to determine the level of the contents of the vessel.

A cooling plate assembly includes an anode half-plate having an anode upper surface and an opposing anode lower surface, and a cathode half-plate having a cathode upper surface and an opposing cathode lower surface, the cathode lower surface configured to engage the anode upper surface. The assembly further includes a cooling tube disposed between and engaging the anode upper surface and the cathode lower surface.

A deaeration device for a fluid includes a reservoir that contains a portion of the fluid, a fluid flow path that carries a portion of the fluid, a pressure regulating structure that creates a pressure gradient along the fluid flow path, a fluid exit in the fluid flow path, and a fluid entrance in the fluid flow path. The pressure gradient causes some of the fluid to exit the fluid flow path through the fluid exit and join the fluid in the reservoir. The pressure gradient causes some of the fluid from the reservoir to join the fluid flow path through the fluid entrance.

An inline process for imparting sonic energy plus a liquid gas separator to a continuous flow of a heterogenous liquid to de-gassify the liquid and thereby provide for separation and extraction of selected liquid and gas components. The device utilizes a flat plate oriented in the direction of flow within the liquid so as to impart pressure fronts into the liquid to initiate liquid gas separation followed by a series of weirs, and tower packing, with stripping gas to facilitate mass transfer.

An oxidation-reduction desulfurization system includes a reactor vessel with sour gas inlet at the bottom and a gas outlet at the top. A primary stage phase separator includes a vertically-oriented pipe with an inlet located inside the reactor vessel. The ratio of the reactor vessel diameter to the pipe inlet diameter is in a range of 2:1 to 5:1. Surface foam and non-gaseous multi-phase mixture including emulsion flow into a partially gas-filled upper section of the vertically-oriented pipe and freefall to a lower level, thereby facilitating mechanical breaking of the foam and the emulsion. A secondary stage phase separator connected to the gas outlet separates non-gaseous surge from sweet gas. Valves and a controller automatically maintain target levels of the non-gaseous multi-phase mixture and non-gaseous surge.

A method comprises controlling an operating pressure of a fluid from a borehole. The fluid comprises solids and entrained gas. The method further comprises removing at least a portion of the entrained gas from the fluid at an upstream location. The method further comprises removing residual entrained gas from the fluid at a downstream location. The method further comprises separating at least a portion of the solids from the fluid. The method further comprises circulating the separated fluid back to the borehole. Separating of solids occurs after the removing of entrained gases from the fluid at the downstream location.

Polymerization unit for producing polymer powder having at least one polymerization reactor for the polymerization of light (co)monomer(s) having less than 7 carbon atoms, and heavy comonomer(s) having at least 7 carbon atoms, and a degassing section including two (and optionally a third) cylindrical degassing vessels in series. Light (co)monomer(s) are degassed in the first degassing vessel (V1) and recovered, and heavy comonomers are degassed in the second degassing vessel (V2) and recovered. The active polymer powder is optionally polished and/or optionally deactivated in the optional third degassing vessel (V3). The cross-sectional area (S2) of the second degassing vessel is greater than 1.5 times the cross-sectional area (S1) of the first degassing vessel [S2>1.5×S1], and vessels V1 and V2 are equipped with a vent recovery unit (VR) for respectively recovering the light (co-)monomer(s) (VR1) and the heavy comonomer(s) (VR2) from the gases exiting the vessels.

A system comprises: a filter for removing at least one of a contaminant or gas bubbles from a liquid photoresist to provide a filtered photoresist at an outlet of the filter. The filter has a filter vent. A trap has an inlet coupled to receive the filtered photoresist from the filter, for removing a remaining contaminant or gas bubbles from the filtered photoresist. One or more valves and one or more conduits are connected to the filter and the trap. The one or more valves are operable to reverse a direction of flow of the filtered photoresist, so that the photoresist flows from the inlet of the trap, through the outlet of the filter, to the filter vent.

Disclose is a separator for separating liquid from a fluid stream including a mixture of gas and liquid. The separator comprises a first vessel including an outlet and an inlet for receiving the fluid stream, the first vessel in fluid communication with a second vessel via a first valve, the second vessel in fluid communication with a liquid outlet via a second valve, wherein the first vessel is arranged to enable the liquid to flow into the second vessel. The separator also has a second valve for controlling release of liquid from the second vessel, the first and second valves being pneumatically operated, the pneumatic operation of the first and second valves allowing only one of the first and second valves to be open during operation of the separator.

A system for deaeration of a liquid comprises a heater for heating the liquid to a well-defined temperature, means for pressurizing the liquid, a first piping for guiding the heated liquid to a separation vessel, a vacuum pump for evacuating deaerated gases from the separation vessel, and a second piping for guiding the deaerated liquid from the separation vessel. The system further comprises an inert-gas supply and a mixer for supplying and mixing in inert gas into the liquid in the first piping. The vacuum pump is controllable to maintain a separation pressure in the separation vessel corresponding to a pressure at or slightly above the saturation pressure.
