Some implementations provide an integrated system that includes: a wastewater treatment system configured to process wastewater released by one or more furnaces at a steelmaking plant, and generates reused wastewater using the wastewater; a heat recovery apparatus configured to utilize exhaust gas from the one or more furnaces at the steelmaking plant, and heat the reused wastewater generated by the wastewater treatment system above a threshold temperature; and a generator configured to receive, through a water inlet, the reused wastewater heated above the threshold temperature; and an absorption system arranged in circulation with the generator, and wherein the reused water is supplied above a threshold amount such that the generator drives the absorption system and produces cooled air inside the steelmaking plant.

A power system includes a first solar power assembly that includes a first working fluid fluidly coupled to one or more components of an industrial process; a second solar power assembly that includes a second working fluid fluidly coupled to an electrical power generation system that is electrically coupled to the one or more components of the industrial process; and a heat recovery system that includes a heat exchanger. The heat exchanger includes an inlet fluidly coupled to at least one of the one or more components of the industrial process to receive waste heat from the at least one of the one or more components of the industrial process, and an outlet fluidly coupled to at least another of the one or more components of the industrial process to supply the waste heat to the at least another of the one or more components of the industrial process.

Managing power usage in an industrial process

An absorption cooling system that includes a plurality of solar collectors, a generator containing a dilute absorbent-refrigerant solution, a condenser, an evaporator, an absorber, a heat exchanger located between the generator and the absorber, first, second, and third storage tanks, a first temperature control valve located between the solar collectors and the first storage tank, a second temperature control valve located between the first storage tank and the generator, and a plurality of additional valves, wherein the first temperature control valve and the second temperature control valve are configured to regulate a flow of a heating fluid into the generator by automatically toggling between an open mode or a closed mode in response to a controller signal indicating a presence or an absence of a set point of a solid absorbent content in the dilute absorbent-refrigerant solution of the generator.

The solar-powered LiBr-water absorption air conditioning system using hybrid storage includes one or more solar collectors generating heat energy to drive the system. The solar collector communicates with a generator to heat an aqueous LiBr solution and release refrigerant through vaporization. The refrigerant feeds into a condenser to form a refrigerant condensate. The condensate feeds into an evaporator, which throttles the refrigerant and causes flash vaporization, resulting in cooling discharged into a load. The refrigerant from the evaporator feeds into an absorber containing a weak LiBr-water mixture from the generator to facilitate absorption of the refrigerant. A pump feeds the resultant aqueous LiBr solution back to the generator for another cycle. The hybrid storage includes a combination of heat storage tank, refrigerant storage tank, and/or a cold water tank coupled to the generator, condenser, and the evaporator to supplement driving or additional cooling during nighttime for continuous daily operation.

An air-cooled, single-effect, air conditioning system includes a first set of solar collectors configured to obtain energy to facilitate release of refrigerant from an absorbent-refrigerant solution in a generator. A tank is configured to store the energy for nighttime operations of the air conditioning system. One or more valves are configured to regulate consumption of the stored energy to maintain continuous cooling of at least one load.
