Vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. The Purge Pump is necessary when the liquid level sender is inaccessible. Process heat exchanger is the most common type of heat exchanger used in higher-pressure and higher temperature applications. Fixed tube sheet heat exchangers are the ones that are very much used in process chemical industries and refinery services, as there is absolutely no chance for intermixing of fluids. This type of heat exchanger is employed where even the slightest intermixing of fluids cannot be tolerated.
