In the Chemical Plant steam is widely used in the process for heating purposes at various pressures. Usually from a saturated low pressure to a Superheated medium to high-pressure Boilers are used to generate the power. The enthalpy drop from boiler pressure to a process pressure is done in a Steam Turbine Generator or a PRV. A plant can be benefitted by generating its electricity by installing a Steam Turbine Generator. The size of a Turbine or a Boiler depends on the plant’s heating and electrical load. Proper application engineering can help to reach the highest overall efficiency by optimizing the Boiler and Turbine Size.

To decide the optimum size of the Boiler and Turbine, the cogeneration option can be looked out during the selection of a Boiler. Any process that produces heat by the exothermic reaction can also be taken into consideration for a waste heat recovery option and condensing or extraction condensing Turbine option. This will help in saving on electricity costs and thus will improve the overall thermal efficiency of the plant. A Turbine as low as 100 kW to 4 MW can be seen for backpressure for an inhouse power generation option. And even above that can be seen as a Captive Power Plant Option.
