Upstream process equipment transmits a predetermined fluid to downstream process equipment. A valve fluidly couples the upstream process equipment to the downstream process equipment. A first pressure sensor and a first temperature sensor are coupled to the upstream process equipment and upstream from the valve. A second pressure sensor and a second temperature sensor are coupled to the downstream process equipment and downstream from the valve. A control system is coupled to the first pressure sensor, the first temperature sensor, the second pressure sensor, and the second temperature sensor. The control system determines a first fluid flowrate of the predetermined fluid using a fluid flow model based on pressure data from the first pressure sensor and the second pressure sensor, temperature data from the first temperature sensor and the second temperature sensor, a size of the valve, at least one fluid parameter regarding the predetermined fluid, and a valve flow coefficient of the valve.

In one aspect, a modular filter assembly for filtering fluid that flows in a flow direction therethrough is disclosed. The assembly includes a first housing section having a first filter element; a second housing section having a second filter element; and a connector disposed between the first and second housing sections. A housing includes the first housing section, the connector, and the second housing section. The flow direction is through the first and second filter elements in series.

A system and method for inerting a protected space is disclosed. Process water is delivered to an anode of an electrochemical cell comprising the anode and a cathode separated by a separator comprising a proton transfer medium. A portion of the process water is electrolyzed at the anode to form protons and oxygen, and the protons are transferred across the separator to the cathode. Process water is directed through a process water fluid flow path including a gas outlet and a gas discharge valve in operative fluid communication with the gas outlet. Air is delivered to the cathode and oxygen is reduced at the cathode to generate oxygen-depleted air, and the oxygen-depleted air is directed from the cathode of the electrochemical cell along an inerting gas flow path to the protected space.

A fluid management system and method includes a thermal management system disposed within a housing that includes conduits extending between a source and a destination of a first fluid. The first fluid exchanges heat with cooling devices as the first fluid moves between the source and the destination. A fluid mixture including the first fluid and a second fluid, and an exhaust are generated responsive to the first fluid exchanging heat with the cooling devices. The exhaust directed toward an outlet of the housing. A separator assembly fluidly coupled with and disposed downstream of the thermal management system receives the fluid mixture and separates the first fluid from the second fluid. The first fluid is directed in a first direction out of the separator assembly and the second fluid is directed toward the outlet to be combined with the exhaust.

A fermentation apparatus for preserving the aroma of a fermentable beverage is provided. The fermentation apparatus comprises a flow passage fluidly connectable to the headspace located above a fermentable beverage in a fermentation container. A carbon dioxide scrubber in the flow passage receives a headspace fluid mixture comprising at least carbon dioxide gas and an aromatic fluid originating from the fermenting beverage. When the headspace fluid mixture contacts the carbon dioxide scrubber, the carbon dioxide scrubber retains a modified fluid in the flow passage. The modified fluid has a lower carbon dioxide gas concentration and a higher aromatic fluid concentration than the headspace fluid mixture. The flow passage directs the modified fluid back to the headspace to at least partially retain the aromatic fluid in the fermentable beverage in the fermentation container. A method for preserving the aroma of a fermentable beverage is also provided.

A base station (1) and a bioprocess system (3), wherein said base station (1) comprises: a frame or housing (5), wherein said frame or housing comprises a number of valves (7a-f, 9a-d, 11a-f, 13a-e, 15a-f) into which a disposable tubing set (21) during run of the system is provided such that at least one inlet (23a-j) of the disposable tubing set is connected to at least one outlet (25a-f) of the disposable tubing set via a bioprocess separation device (31) of the bioprocess system (3); and a movable pump holding device (35), which can be provided in at least two different positions, whereof one is within the frame or housing (5) and another is at least partly outside the frame or housing (5) and which comprises at least one pump main body (37), said pump main body comprising a connection (39) configured for connecting to a disposable pump connection part (27) comprised in the disposable tubing set (21).

Degassing device for degassing a liquid flow, including: a housing for receiving liquid from the liquid flow therein, the housing having one or more ports for connecting to the liquid flow; a valve arranged for allowing gas to escape from the housing; and a heater arranged at least partly inside the housing for raising a temperature of the liquid received in the housing with respect to a further temperature of the liquid flow.

Disclosed is a cooling system comprising: a first cooling circuit with a first coolant pump; a second cooling circuit with a second coolant pump; an expansion tank provided with an expansion chamber for accumulation of coolant, wherein the expansion chamber is connected to the second cooling circuit to allow the expansion chamber to receive coolant from the second cooling circuit; and a deaeration device arranged in the first cooling circuit for separation of air bubbles from the coolant circulating therein. The deaeration device is located at a lower position than the expansion tank and connected to said expansion chamber via a static line to allow air bubbles separated from the coolant in the deaeration device to migrate upwards in the static line towards the expansion chamber.

Various embodiments relate to devices and methods for treating a mixture of expansion gas and filling product foam in a beverage filling plant, comprising the steps of introducing the mixture of expansion gas and filling product foam into a closed separation container and extracting the expansion gas out of the closed separation container via suction.
