Seawater desalination equipment includes a gas generation unit for generating gas from seawater by evaporating the seawater, a condensation unit for receiving and condensing the gas to generate freshwater, a cooling unit, a gas storage unit connected to the condensation unit and storing gas that has passed through the condensation unit, a vacuum pump, and a control unit for operating the vacuum pump that is configured to discharge the gas stored in the gas storage unit to an outside area when an internal gas pressure difference between the condensation unit and the gas storage unit is within a predetermined range. The condensation unit includes a condensation pipe having a zigzag shape and through which the gas passes. The cooling unit supplies the seawater to the outer surface of the condensation pipe to lower a temperature of the condensation pipe by evaporating the seawater.

A process includes continuous steps and batch steps for recycling waste oil, fuel or antifreeze. The continuous steps include determining the volume of waste; pumping waste toward a distillation vessel; mixing waste with heated waste, and while flowing the waste into the distillation vessel performing steps of: maintaining a vacuum; heating the waste; returning a first portion of heated waste to the distillation vessel and a second-portion to mix with the waste feed; sending gaseous vapors to a condenser; returning some condensed liquid to the distillation vessel; and delivering condensed liquid as a product. The batch steps include: stopping waste flow into the distillation vessel; reducing pressure; heating the waste; returning the heated waste to the distillation vessel; condensing gaseous vapors; returning some condensed effluent to the distillation vessel; delivering some condensed effluent as a first product; and delivering heated waste as a second product.

A gravity power and desalination technology system is provided, including a heat storage apparatus, an inner tube portion, a hot-air and vapor generator, and venting holes, a corrugated tube portion, an outer tube portion, an updraft wind power generator, and an artificial hydro power generator. The heat storage apparatus is provided in a lower portion and configured. The inner tube portion has an inner vent portion inside and disposed vertically over the heat storage apparatus. The hot-air and vapor generator is disposed between the heat storage apparatus and the inner tube portion. The venting holes are bored through the inner tube portion obliquely outwards. The corrugated tube portion is provided on a top portion of the outer tube portion. The updraft wind power generator and the artificial hydro power generator are installed in the lower portions of the inner vent portion and the outer vent portion, respectively.

A system for reclaiming contaminated water from a cooling tower in a power generation system includes a contaminant collection heat exchanger that receives a supply of extraction steam from the power generation system, and to receive and concentrate contaminants in the contaminated water by boiling the contaminated water and producing process steam using thermal energy from the extraction steam. A concentrate condensation device receives and further concentrates the contaminants collected in the contaminant collection heat exchanger. A process, heating, condensing and/or electrical generation subsystem receives the process steam from the contaminant collection heat exchanger.
