The invention relates to methods, systems and apparatus for distributed management of raw water and internal combustion engine (ICE) gas emissions generated during industrial operations. One aspect of the invention at least partially utilizes a hot gas air knife to increase or partially increase surface area between a raw water and a hot gas in order to vaporize a proportion of the aqueous phase of the raw water and concentrate contaminants within a residual raw water concentrate. The water vapor generated by the vaporization process may be demisted, discharged directly to the atmosphere or alternatively condensed and captured for use. Another aspect relates to how the liquids and gasses interact to continuously flush the surfaces of the system which may help mitigate scaling issues. The invention may help facilitate rapid transfer of ICE combustion gas particulate and ICE combustion gas chemicals onto and into the raw water as it concentrates.

In a method for regulating at least two fluids, a fluid feed flow Q is divided into n parts, the sum of the n parts being equal to Q, each of the n parts is sent to one of n processing units, each of the n processing units produces at least one processed flow, at least one processed flow of a first of the processing units is regulated by control means in order to keep the flow thereof constant at a value Q1 in nominal operation, at least one processed flow of a second of the processing units is regulated by control means in order to keep the pressure thereof constant in nominal operation and, in the event of a reduction of the feed flow Q, in reduced feed operation, if, preferably only if, the flow of the flow processed in the second processing unit of step v) drops and thus reaches a first minimum flow threshold, a processed flow in the first processing unit is regulated such that the processed flow having a value Q1 in nominal operation is reduced to a value less than Q1.

Techniques for humidifying a gas stream using a hydration system includes directing a gas stream through a contact zone of at least one hydration system; directing a hydration solution into the contact zone using a pump; contacting the gas stream with the hydration solution; evaporating water from the hydration solution into the gas stream to form a humidified gas stream, transporting the humidified gas stream out of the at least one hydration system; and collecting the remaining hydration solution in a hydration solution collection basin below the contact zone. The at least one hydration system is fluidly coupled to at least one downstream process and the humidified gas stream from the at least one hydration system is transported as a feed stream to the at least one downstream process.

The present system is for integrated management of associated gas and produced water at oil well extraction sites. The system includes a controller that makes gas allocation determination (e.g., directs conditioned gas to (i) gas flare, (ii) produced water reduction system, and/or (iii) generator) when a change in conditioned gas flow is detected based on first plurality of inputs. If the conditioned gas is directed to the generator, then the controller makes an electricity allocation determination (e.g., (i) increase a data processing operating rate on a data processing server, (ii) start up idle data processing equipment, (iii) direct generated electric current to a power grid, and/or (iv) charge a storage battery) based on second plurality of inputs. By operating the system of gas consumption and electricity production/consumption in an integrated fashion, benefits of flaring prevention, resource conversation, and more efficient economic operations are optimized to a degree not previously attainable.
