The functioning of an FGD scrubber involves a process called wet scrubbing. Here, the flue gas is introduced into a chamber where it comes into contact with a liquid absorbent, typically-(limestone-gypsum wet FGD). The chemical reaction between the absorbent and the sulfur dioxide results in the neutralization of the gas, converting it into a solid form that can be easily removed and disposed of safely.

One common type of vessel is the pressure vessel, which is designed to hold gases or liquids at a pressure significantly different from the ambient pressure. These vessels are commonly used in industries such as oil and gas, petrochemical, and energy production. They must be carefully designed and constructed to withstand the high pressures and temperatures they are subjected to.

The manufacturing process of PP FRP tanks involves a meticulous fusion of glass fibers and a polypropylene resin matrix. The fibers provide tensile strength, while the resin binds them together, creating a composite material that is stronger than either component alone. This construction method ensures the tanks are not only strong but also resistant to cracking, leakage, and structural failure.

The thread button bit, also known as a tap drill bit or a threading bit, is an essential component in the process of thread cutting. Its design incorporates a button-shaped projection at its end, which not only aids in the initial piercing of the material but also contributes to the accuracy and stability during the threading operation. The 'button' serves as a cutting edge, shearing off material as it rotates, gradually forming the required thread pattern.
