Cement Grouting Injection Piston Pump/Slurry Pump

In order to achieve optimum process operations, it is essential to use the right type of process equipment in any given process. Heat exchangers, commonly used to transfer energy from one fluid to another, are no exception. The selection of the proper type of heat exchangers is of critical importance. Selecting the wrong type can lead to sub-optimum plant performance, operability issues and equipment failure.

The following criteria can help in selecting the type of Heat Exchanger best suited for a given process:

· Application (i.e. sensible vapor or liquid, condensing or boiling)

· Operating pressures & temperatures (including startup, shutdown, normal & process upset conditions)

· Fouling characteristics of the fluids (i.e. tendency to foul due to temperature, suspended solids ...)

· Available utilities (cooling tower water, once through cooling water, chilled water, steam, hot oil...)

· Temperature driving force (i.e. temperature of approach or cross and available LMTD)

· Plot plan & layout constraints

· Accessibility for cleaning and maintenance

· Considerations for future expansions

· Mechanical considerations such as: 1) material of construction; 2) thermal stresses (during startup, shutdown; process upset and clean out conditions); 3) impingemen protection
