Air cooled condensers to save water for cement units
Thermax SPX Energy Technologies Ltd, the joint venture, bagged an order for seven air cooled steam condensers from the cement conglomerate, Nuvoco Vistas Corporation (formerly Lafarge). The condensers will be installed at cement plants in Rajasthan, Chattisgarh and Jharkhand – three for waste heat recovery systems (WHRS) and four for captive power plants (CPP).
Air Cooled Condensers (ACCs) utilise ambient air for cooling – an effective alternative to the wet cooling towers used earlier by captive power plants in the cement industry. ACCs are environment friendly in many ways. They save water in water-scarce areas since no water is required for cooling. They reduce the use of chemicals for water treatment, bring down corrosion in auxiliaries, and eliminate plume, blowdown and treatment of associated discharge water.
The scope of the project includes design, engineering, manufacturing, construction and commissioning at site as well as performance guarantee testing before handing over. The commissioning of the WHRS and CPP units will take place over the next 12 months. This is the JV’s largest order from a single customer, bagged against stiff competition.
