Exchangers

Exchangers are widely used for both cooling and heating large scale industrial processes. Heat exchangers work to stabilize the operation of the plant by recovering heat and transferring it to another part of the process. This practice saves money, as the heat supplied to other streams from the heat exchangers would otherwise come from an external source — which is more expensive and more harmful to the environment.

Because there are usually several interrelated exchangers in a system, any malfunction can be compounded. Due to the corrosive nature of much of the chemical / petrochemical media, maintenance of the exchangers is a continual concern. Isolation of the exchangers for repair, re-tubing or cleaning is imperative for the integrity of the process, and can have a direct impact to the operations budget. The ability to install these critical isolation valves horizontally or vertically is also an important factor in choosing the correct valve type. MOGAS quarter-turn metal seated ball valves can be installed in either configuration, reducing the need of numerous spare valves.

Typical tasks of exchangers in chemical / petrochemical plants include:

Heating and cooling of acids and caustic solutions
Cooling of highly viscous products

Tempering and condensation of solvents, exhaust vapor and steam
Cooling of water circuits
