Shell-and-Tube Heat Exchangers Are Process Workhorses

Shell-and-tube heat exchangers represent one of the most widely used means for heat transfer in industrial process applications. According to www.ketemalp.com the web site for Ketema LP, Grand Prairie, Texas, shell-and-tube heat exchangers frequently are selected for duties such as:

Process liquid or gas cooling.

Process or refrigerant vapor or steam condensing.

Process liquid, steam or refrigerant evaporation.

Process heat removal and preheating of feed water.

Compressor, turbine and engine cooling, oil and jacket water.

Thermal energy conservation efforts and heat recovery.

Hydraulic and lube oil cooling.

Shell-and-tube heat exchangers can transfer large amounts of heat in relatively low cost, serviceable designs. They can provide large amounts of effective tube surface while minimizing the requirements for floor space, liquid volume and weight. Shell-and-tube units come in a range of sizes.

Avoiding scale, corrosion and microbiological growth — all of which diminish effective heat transfer — is the focus of any water treatment approach for water-contacted process heating and cooling equipment.
