Gas Purification

Description of the Plant of Gas Purification

All elements of the Gas Purification plant are placed on a frame made of square pipes 40x40x2 mm of stainless steel. The four branches of the Gas Purification plant are in the same horizontal plane. The Gas Purification plant is complete with a control cabinet, integrated into the structure, with all the switches that are necessary for the activation of the different electrical components of the plant, a main switch off and emergency stop mushroom button. Inside the cabinet there are also the necessary protections against potential electrical faults, short circuits or drift to earth, according to the electrical regulations governing the protection of people and equipment.

The Gas Purification plant allows testing the removal of solid particles from a gas stream, through different methods:  

1. Static settler
2. Dynamic settler
3. Cyclonic separator, 

And comparing the three processes.The contaminant, solid, is stored in a hopper, from where it is dosed to the process by means of an archimedes screw which is directly actuated by a gear motor.  

Operation of the Gas Purification Plant

The Gas Purification through the plant is obtained by operating a blower of 1.1 kW, 900 m3 maximum flow and 475 mm CH2O of pressure; it is possible to change the flow of the circulating air by means of a frequency inverter that acts on the rotational speed of the blower motor.The contaminant is introduced into the suction of the blower so that at the outlet we have, already mixed, the air and the solid contaminant. The rest of the circuit as well as the particle separators are made of transparent methacrylate in order to visualize the entire process. The gas stream can be led in four branches, each one offering a different process for separating the contaminant; each of these branches can be easily removed, independently from the rest, because in each branch there is a valve and a union nut: 

1. In the first branch the gas stream is not treated, so it acts as a target and we can later compare the concentrations of particles at its outlet with those obtained through the other branches.
2. In the second branch the gas stream passes through a static separator where we have the separation of cleaned gas and particles.
3. In the third branch the gas stream passes through a dynamic separator where we have the separation of cleaned gas and particles.
4. In the fourth branch we have a cyclone separator made in transparent methacrylate.
