Paras Petrofils, a polyester yarn manufacturer in Gujarat, has gained better energy efficiency, investing in CHPC (combined heating power and cooling) solutions from Thermax.
Like many industries in gas rich areas, Petrofils relies on a gas engine for its power needs and grid power as standby. Though cost of electricity is cheaper this way, compared to grid power, it is also highly inefficient as gas engines work at around 40 percent thermal efficiency. Thermax plugs the energy leak with its Energen, a new generation waste heat recovery boiler coupled to an absorption chiller. Energen taps the waste heat from the gas engine and converts it to steam, which in turn runs the chiller. With this project in place, the client is harnessing waste heat for extra heating and cooling. It has already recovered its investment in just eight months through energy savings.
Tessitora Monti, an Italian textile unit in Kolhapur is another client that has opted for the CHPC route to efficiency by installing an Energen (on furnace oil) along with a double effect absorption chiller.
