Shell And Tube Heat Exchangers

Shell and tube heat exchangers are the types of heat exchanger designs. Also, it’s the most frequent type of heat exchanger in refineries and other large chemical processes because it’s suited for high-pressure applications.

Due to constant work, shell and tube heatexchangers can accumulate fouling. Fouling in heat exchangers leads to numerous problems like reduced thermal activity, increased temperature on the hot side, decreased hot flux, and decreased temperature on the cold side; induced corrosion etc. All these problems can affect the performance of heat exchangers and overall plant or refinery.

The best way to prevent these problems to occurring in heat exchangers in your plant or refinery, they have to be cleaned thoroughly. Cleaning requires implementation of different methods to remove unwanted materials.

Dunn Heat Exchangers provides five cleaning methods for shell and tube heat exchangers cleaning methods such as:

Hydroblast and waterlance cleaning

They are the most frequently used cleaning methods. Hydroblasting is defined as a method which relies solely on the energy of water. The primary aim of water is to strike the fouled process equipment in order to achieve effect of cleaning. On the other hand, waterlancing is a technique where steam generators are used to clean the surface. Both methods don’t include usage of abrasive or chemical substances. Hydroblasting and waterlancing should be conducted with high-quality equipment which includes blast nozzles that are able to flow heated water to optimum GPM (Gallon per Minute) and PSI (Pounds per Square Inch) to provide adequate temperatures essential for cleaning of fouled heat exchangers. It’s worth to mention that our company owns the biggest, most-modern, and best-equipped heat exchanger cleaning facility in the country.

Grit blasting cleaning

This method is conducted by using steam of abrasive materials to strike the surface in order to eliminate the accumulated fouling. Abrasive materials vary and include walnut shells, silicon carbide, emery particles etc. Grit blasting cleaning is processed in enclosed grit houses and cleans shell and tube heat exchangers thoroughly.

Chemical cleaning

It incorporates the implementation of chemical components for removing deposits. Some of the processes of chemical cleaning include cleaning with alkali, cleaning with acid, protecting metal surfaces with alkali (to prevent corrosion), and rinsing.

Bake-Out/Pyrolytic Cleaning Process

It’s the process where heat is used to remove fouling. It thermally decomposes any residue and is safe for the fouled process equipment. It includes placing the heat exchanger in the vacuum chamber where it’s heated to remove fouling.

Decommissioning

The method is mostly performed on fouled equipment that will be returned to service and usually includes other methods of equipment cleaning as well, such as bake-out process.

Due to the best heat exchanger cleaning facility in the US, knowledgeable staff who incorporate various methods to get things done, and high-quality equipment, Dunn Heat Exchangers Inc. should be your first choice for cleaning of shell and tube heat exchangers.
