摘要： A system for opening and closing a mixing manifold includes a drive motor, a cam plate, and a valving rod connector. The drive motor imparts movement in first and second directions. Movement imparted in the first direction causes the cam plate to move linearly in a third direction and movement imparted in the second direction causes the cam plate to move linearly in a fourth direction. Movement of the cam plate in the third direction causes the valving rod connector to move linearly in a fifth direction and movement of the cam plate in the fourth direction causes the valving rod connector to move linearly in a sixth direction. Movement of the valving rod connector in the fifth direction causes retraction of a valving rod of the mixing manifold and movement of the valving rod connector in the sixth direction causes extension of the valving rod.

摘要： Systems and methods are described for supplying a rinsing liquid including ultrapure water and an ammonia gas. The system includes an ultrapure water source and a gas mixture source in fluid communication with a contactor. The gas mixture includes ammonia gas and a carrier gas. The system includes a control unit configured to adjust a flow rate of the ultrapure water source such that an operational pressure of the contactor remains below a pressure threshold. The system includes a compressor configured to remove a residual transfer gas out of the contactor. The contactor generates a rinsing liquid having ultrapure water and a concentration of the ammonia gas dissolved therein. The system includes a pump in fluid communication between the contactor and an outlet. The pump is configured to deliver the rinsing liquid having a gaseous partial pressure below the pressure threshold at the outlet.

摘要： A technique facilitates mixing of fluids for use in well treatment operations. According to an embodiment, a dry powder material, e.g. a friction reducer, may be thoroughly mixed into fluid or fluids associated with a well treatment operation. The powder material is combined with liquid, e.g. water, via a series of Venturi mixers arranged to thoroughly mix the materials. In some applications, the Venturi mixers are mounted on a modular unit which is readily moved to a desired wellsite. Additional modular units may be added to increase the amount of product being mixed according to the demands of a given well treatment operation, e.g. a hydraulic fracturing operation.
