The present invention relates to an apparatus and a method of removing water contained in a gaseous material. An apparatus of removing water by phase-changing water contained in a gaseous material to a frost phase includes a gas inflow unit 100, a main body 200, a discharging unit 300, and a frost discharging unit 400. A method of removing water by phase-changing water contained in a gaseous material to a frost phase includes phase-changing water contained in gas to a frost phase, separating the phase-changed frost and the gas from which water is removed, discharging the gas from which the water is removed to the outside, and discharging the phase-changed frost to the outside.

There is disclosed a method and an apparatus for reducing the amount of waste, requiring special handling and possible destruction, in a process involving vaporization, in an evaporator apparatus (1-6, V1-V6), of a water solution containing environmentally hazardous substances. A considerable amount of the water content of said water solution is vaporized in a reusable vaporization chamber (2a). At a certain time, the vaporization process is stopped, so that the remaining water content is 70% to 5% of the initial water content. Thereafter, in a second step, the remaining water solution in the reusable vaporization chamber (2a) is transferred into a separate waste isolating container (6), where the remaining water is subjected to at least one further water-reducing process. The remaining waste, including the environmentally hazardous substances, is left in the waste container for separate handling and possible destruction.

Provided are a waste gas processing device, a vacuum coating system, and an operation method of the waste gas processing device. The waste gas processing device is configured to remove and recover arsenic in the waste gas, and includes a condensation portion and a scraping portion. The condensation portion is provided with a condensation cavity, and an air inlet, an air outlet and a discharge port communicated with the condensation cavity. A partial surface of the scraping portion abutting against an inner wall surface of the condensation cavity. The present disclosure solves a problem in a conventional art that an economic cost of a waste gas processing device is too high during the removal and recovery of arsenic in waste gas.

The condensation portion is provided with a condensation cavity, and an air inlet, an air outlet and a discharge port communicated with the condensation cavity. The condensation portion is configured to cool waste gas charged into the condensation cavity from the air inlet, so that gaseous arsenic in the waste gas is condensed on an inner wall surface of the condensation cavity by cooling to form solid arsenic. The scraping portion is rotatably provided in the condensation cavity, and a partial surface of the scraping portion abuts against the inner wall surface of the condensation cavity.

A method for separating components from a fluid is disclosed. A cooling element is provided and is disposed in contact with a distal side of one or more thermally-conductive surfaces. One or more resistive heating elements are provided and are disposed in contact with or embedded in a proximal side of the one or more thermally-conductive surfaces. A fluid comprising one or more secondary components is provided.
