The Computer Controlled Gas Washing Processing Plant, "PLGC", 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.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
