Electroplating is a method that creates a thin layer of metal on a cleaned metal surface by utilizing electric current. The process involves cleaning and pretreatment of a metal surface with strong acids and surface-stripping agents, like caustic soda and chlorinated hydrocarbons. The process also involves other harmful and toxic substances, e.g. cyanides. Consequently, the vapors...

Air Scrubber Clogging: Venturi, Cyclone, Packed Bed Scrubbers
Accumulation of unwanted materials — clogging and fouling — is detrimental to the working function of a scrubber: it disrupts its working cycle and leads to complications and more frequent maintenance. The clogging of an air scrubber occurs due to the high particulate matter (PM) concentrations in the gas that is being treated. Over time...
Venturi Wet Air Scrubber
Venturi scrubber is a type of wet air scrubber, which means that it uses water or other liquid to scrub air. It is designed to use the energy of an incoming gas stream in order to atomize scrubbing liquid. Venturi wet scrubbers are the most popular type of scrubbers; they have been used in the...
Packed Bed Scrubbers
The packed bed is often used in air scrubbers, it is a hollow tube or pipe filled with a specifically designed packing material. Packed beds are used to improve contact between different stages of a chemical reaction or another process that is similar, for example, distillation processes or air scrubbing. The purpose of a packed...
Flue Gas Desulphurisation Uses and Perspectives
To address the environmental effects of power plants that utilize specific difficult coal types, flue gas desulphurisation (FGD) strategies must be advanced to attain improved treatment quality and optimal operational efficiency. FGD technology is built on the chemical reaction that occurs between the warm exhaust gases and limestone. This reaction subsequently reduces around 90% of...
