A system for deaeration of constituents of a liquid product blend includes a first liquid stream supply system and a second liquid stream supply system. A control system is configured to: (i) monitor flow of the first liquid and responsively/automatically control flow of the first deaeration gas in order to achieve a first target ratio of first deaeration gas to first liquid; and/or (ii) monitor flow of the second liquid and responsively/automatically control flow of the second deaeration gas in order to achieve a second target ratio of second deaeration gas to second liquid; and/or (iii) monitor a dissolved oxygen level of (a) the first liquid, at a location downstream of injection of the first deaeration gas, and (b) a combined liquid formed by mixing the first liquid and the second liquid, and to adjust the system based upon the dissolved oxygen level of the combined liquid.

A system and method of injecting a chemical into a high pressure process stream without pumps or other active components. The system utilizes the differential pressure created by resistive losses of downstream components within a high pressure process stream. A bypass side stream is taken from an upstream pressure location and returned to the downstream side of the resistive inline process component. The chemical solution vessel is pressurized by the higher side of the pressure differential. The solution then passes through a flow controlling capillary tube exiting on the lower pressure differential side into the bypass stream. The high flow rate chemically diluted bypass stream then returns to the process stream at the lower differential process stream tie-in. The chemical solution is isolated from the process water pressuring the vessel by a movable separating device preventing mixing of the two fluids. The vessel can also be pressurized by gas.

A system for mixing acid and water can include a tank for holding acid, an acid pump for pumping acid out of the tank, an acid control valve, a water pump for pumping water, a water control valve, a flush valve to selectively flush the system with water, and a controller to control the pumps and the valves. The acid control valve and/or the water control valve can be an electronically controlled valve. The flush valve can be an electronically controlled valve to selectively permit water to flow from downstream of the water pump to upstream of the acid pump. The acid control valve, the water control valve, the flush valve, or any combination thereof can be throttled by the controller to control flow therethrough.

Systems and methods for injecting hydrogen into a natural gas pipeline to lower the carbon intensity of the resulting fuel blend while achieving the required energy output thereof for the end user. In one embodiment a blend ratio for the blended fuel comprising hydrogen and natural gas is determined based at least in part on a minimum energy output for fuel combusted at an end-use location connected to the natural gas pipeline so that the blended fuel (i) has a lower carbon intensity than a natural gas stream flowing in the natural gas pipeline, and (ii) provides at least the minimum energy output when combusted at the end-use location. Further, one or more embodiments include adjusting a control valve of a hydrogen injection assembly connected to the natural gas pipeline upstream of the end-use location based at least in part on the blend ratio to thereby mix hydrogen into the natural gas pipeline and produce the blended fuel.

A pump device (1) comprises a centrifugal pump (2) and a mixing unit (4) in which two fluids are mixed. The mixing unit (4) comprises a flapper valve (10) configured to move between a first and a second position in which it closes a first inlet (7) and a second inlet (8) of the mixing unit, respectively. At least one of the inlets houses a movable piston (13) which is biased towards being in contact with the flapper valve. The piston has at least one piston channel (15) or annular space (23) through which the fluid flows in to the mixing unit in a controlled manner.
