Skid Mounted Heat/Cool package

A client in Scotland required a single fluid system for heating, cooling and chilling two reactors in a new process.The fluid system had to use existing site services where possible and be situated in a Zone 2 hazardous area. TFS designed 2 Temperature Control Units skids linked to a common expansion tank to operate on Downtherm Q at temperatures between 0°C and 230°C.Each TCU was designed to match the heating and cooling requirements of two very different sized reactors. Both TCU circulated the Heat Transfer Fluid at a constant rate around the reactor jacket during the heating and cooling phases. Equipment Selection One TCU was designed to heat using steam to 130°C then up to 230 using an electric heater. First stage cooling was achieved in a heatexchanger using tower water and the final cooling was achieved using bone at -17°C in a titanium plated heat exchanger. TCU2 had eletric heating only with cooling using tower water. Process Description Both TCU were designed to ensure heating and cooling of teh reactors was aachieved in the specified time . To enable the TFS supplied the control systems panels located in a safe area. The controls switched each heating and cooling reginne brine to ensure the minimum processing times were met.
