Supply side energy efficiency improvements in steam generation at CSL.” By Chemplast Sanmar Ltd
For meeting the plant’s Thermal energy requirement, an 8TPH LSHS based boiler has been installed as a primary source. However in order to eliminate the use of the LSHS boiler, a 4.6 TPH waste heat recovery boiler (WHRB) has been installed, which utilizes the waste gases from IC engines. The project activity helps in improving energy efficiency in the plant by cutting losses through utilization of waste gases. In the absence of the project activity, steam would have been generated using the 8 TPH LSHS boiler, which has been installed as a primary option (it is used as fallback option after commissioning of WHRB). This has resulted in GHG emissions reduction associated with the burning of LSHS.

Waste Heat Recovery based captive power generation by SKS Ispat Ltd
The company has set up an integrated sponge iron plant of 2,10,000 MT capacity at Village Siltara, district Raipur, Chattisgarh. There are 2 X 350 TPD Kiln and 2 X 100 TPD Kiln for sponge iron production. Total Heat Energy as available from the Direct Reduced Iron (DRI) Gas of 2 X 350 TPD Kiln and 2 X 100 TPD Kiln, on conversion to Electrical Energy, produces about 25 MW of Electrical Power respectively. Harnessing this Power by establishing a suitably designed Captive Power Plant at the tail end of the 4 numbers of DRI Kilns enables the company to be self reliant in the arena of Power requirement for production of Steel and to reduce emissions of green house gases into the atmosphere by displacing grid power use as the case was prior project activity which is primarily fossil fuel based.

Destruction of HFC-23 at refrigerant (HCFC-22) manufacturing facility of Chemplast Sanmar Ltd
HFC-23 is an inevitable by-product generated during production of HCFC-22. HFC-23 has a high Global Warming Potential (GWP) (11700 – reference: The IPCC 2nd Assessment Report).
As there is no active market for sale of HFC-23 and as there are also no regulatory mandates by the Government of India to destroy it, HFC-23 is normally released into the atmosphere. It is technically possible to eliminate HFC-23 but abatement procedure requires intervention and carries capital and operating cost. Being environmentally & socially conscious, company has decided to undertake the project activity of capturing and decomposing HFC 23 that would otherwise be released in to the atmosphere and back it up with the revenues generated from CER sale accruing from it.
