The Gas Washing Processing Plants are used to eliminate the presence of gases such as carbon dioxide or sulfur dioxide, among others.
They also contribute to eliminate fogs or dusts for the environment. Besides, they have other applications such as the products recuperation from process gases, gases desorption and gases condensation and cooling.
The sectors where this technology can be applied are mainly the mineral chemistry, pharmaceutical industry, metallurgic industry and the waters treatments, etc.
PLGC unit, designed by EDIBON, allows to evaluate the operation of a gas washing plant, analyzing its efficiency.
The unit has a water feed tank, from which and by means of a water pump, the water is pumped to the upper part of a column. The solids are added by means of a solid dosing system to the air current, which is introduced in the column by its lower part. The water pumped to the upper part of the column is pulverized, by means of showers, to drag the added solids in the air current.
This column has Raschig rings, which increase the surface of interchange between the water and the polluted air current.
The unit has two flow sensor and flowmeters: one to measure the water flow and the other one to measure the air current.
The water current that flows through the bottom of the column goes to a reaction tank. This tank has an stirring system and a pH sensor.
The current is mixed with the flocculant. It will produce the later sedimentation of particles and their decantation. Thus, we can separate a sludge current and a clean current.
