A dosing machine for dosing fluid products includes: containers having vertical longitudinal axes and configured to contain fluid products, rotary stirring elements located inside respective containers and operable in rotation by electric motors, and a dispensing head having nozzles connected to respective containers, where each container is associated with a level measuring device having: a floater containing a permanent magnet and free to move inside the container, a magnetic detector arranged outside the container, and having magnetic sensors spaced apart from each other in a vertical direction and each of which is configured to detect a variation in a magnetic field caused by passage in its proximity of said floater, and a control unit which analyzes signals provided by the magnetic sensors to detect a fluid level inside the container and passage of the floater in a vicinity of one or more of said magnetic sensors.

A flow management and separation system for a horizontal wellbore having a primary artificial lift device having an intake has (a) a sealed central flowpath from a fluidseeker weighted keel inlet, through a recovery flow tube, a seal bore extension and a dip tube having a pump intake sealing assembly in fluid communication with the lift device intake; and (b) a mixed fluid flow path from a fluidseeker internal bypass passage, through an annulus of at least one slug catcher comprising a perforated shell.

A tinting system includes a storage system and a colorant dispenser. The storage system includes a container that defines a fluid-tight, sealed chamber within which a colorant containing reduced levels of biocide (fungicide and/or bactericide) is stored. A valve is positioned at and sealed to an opening provided in the container. The colorant dispenser includes an inlet configured to be releasably and removably attached to the valve of the container. A pump and dosing valve of the colorant dispenser are operated to dispense colorant from the storage system through a discharge nozzle of the colorant dispenser. The dispensed colorant may be used to tint an aqueous-based paint.

Disclosed are a process and system for preparing a catalyst slurry. The process can include preparing a catalyst slurry comprising a solid particulate catalyst and a carrier liquid in a catalyst slurry preparation system. The catalyst slurry preparation system can include a mixing vessel, a rotatable impeller system connected to the mixing vessel, and a motor connected to the rotatable impeller system. The rotatable impeller system can include an agitator shaft and a hub connected to the agitator shaft. The hub and at least a portion of the agitator shaft are positioned within the mixing vessel along a longitudinal axis of the mixing vessel, and the hub has at least three blades.

A storage container for storing quantities of acids and other volatile liquids is described having a recirculation system that can include a recirculation pump and a recirculation line that goes from a bottom end of the container toward a top end of the container, where the recirculation line has a plurality of pressure relief valves spaced along its length. The storage container may also include a leak detection system and a high level warning system.
