A vacuum line and method for controlling a vacuum line in which an auxiliary pumping device and a diluent gas injection device are controlled according to a first operating mode in which the pressure prevailing in the discharge pipe is maintained at less than or equal to 20,000 Pa or according to a second operating mode in which the pressure prevailing in the discharge pipe is greater than 20,000 Pa, and the injection of a diluent gas into the stream of the pumped gases is controlled, downstream of an intake of the rough pumping device, such as into the discharge pipe and/or into the rough pumping device and/or into the auxiliary pumping device by the diluent gas injection device in the second operating mode.

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.

In one embodiment, the present system describes a system wherein a first fluid is within a tank. An intermittent mixer is used for agitating the first fluid within the tank. At least one data acquisition device within the tank is capable of measuring at least one characteristic within the first fluid. In the embodiment, at least one data analyzer is capable of receiving the characteristics within the first fluid, comparing the characteristics within the first fluid to the characteristics of a second fluid, generating a data packet which contains a calculated operational speed and an operational time needed for the intermittent mixer to agitate the first fluid to obtain the characteristics of the second fluid and transmitting the data packet to the intermittent mixer. In this system the intermittent mixer is capable of altering the first fluid within the tank into the second fluid.

A system for agricultural irrigation water oxygenation for enriching soil oxygen level comprises a source of compressed oxygen (and not compressed air) coupled to a water line feeding an irrigation system, such as a drip irrigation system. The coupling system may include a pressure sensor for measuring the pressure in the water line, a solenoid safety valve, a control valve, a flow meter and a controller that controls the flow of oxygen from the source of compressed liquid oxygen to the water line using the components of the coupling system, without using a special cavitation valve and using off-the-shelf components while achieving the same benefits as a system incorporating the special cavitation valve.
