The present disclosure relates generally to processes for separating an effluent in an acetic acid production unit. Accordingly, one aspect of the disclosure provides a process including transferring at least a portion of a carbonylation reaction effluent to the bottom section of a tank, evaporating at least a portion of the effluent to form a vapour fraction, spraying a spray liquid onto a porous demister surface of a demister section of the tank, collecting and returning a liquid fraction of the effluent from at least one chimney tray in the tank to a fractionation section or the bottom section of the tank, and withdrawing from a top section of the tank at least a portion of the vapour fraction, the vapour fraction comprising acetic acid, the vapour fraction having been passed from the bottom section through the fractionation section, and then through one or more chimneys of the at least one chimney tray, and then through the spray section, and then through the porous demister surface of the demister section.

The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.

A sewage treatment machine comprising: a closed container inside which the liquid to be treated is brought to boil; a vacuum-generating apparatus, which is adapted to maintain the inside of the closed container at a given pressure having a value lower than the environmental/external pressure; a heat-pump assembly which is associated to the closed container so as to be able to transfer heat to the liquid present on the bottom of the closed container, thus to bring said liquid to boil, and simultaneously remove heat from the vapours that reach the top of the closed container, thus to condense the vapour and obtain a distilled liquid, and which contains a refrigerant fluid comprising one or more gases of the family of the hydrofluoroolefins in a percentage greater than 3%.

An evaporation system for spray evaporating undesired water comprising: a first pump, a container comprising a sump, a second pump, a spray manifold comprising a spray nozzle, a packing system disposed within the container, a third pump, and an air system comprising an air blower and an air preheater is disclosed. An outlet of a water inlet is connected to an inlet of the first pump. A first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water. A second portion of the ceiling is adjacent to an upper edge of a wall of the container. An outlet of the first pump is connected to an inlet of the container. An inlet of a draw line is disposed in the sump; and an outlet of the draw line is connected to an inlet of the second pump. An outlet of the second pump is connected to an inlet of the spray manifold. The spray nozzle discharges water droplets onto the packing system. An inlet of the third pump is connected to an outlet of the sump. An outlet of the third pump is connected to a discharge outlet. The air system is disposed through the wall of the container; and the air system discharges air flow counter to and/or crossways to the water droplets from the spray nozzle. A method of using the evaporation system is also disclosed.

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.
