incorporated into the clinker in a practically irreversible manner. No waste is generated that requires subsequent processing. - Conservation of fossil fuel resources. - Immobilization of toxic and heavy materials. 1.03 MHIPL installed fool proof system at its Mellacheruvu unit for firing hazardous waste in kilns with detail study by in-house CRH expert and technological support: from FLS world class equipment have been nstalled. During unloading and storage of hazardous liquid nitrogen blanketing is provided by nitrogen generator Installed. Nitrogen is 1.04 Teething Problems during Operation During operation of the system, experienced the problems like pump failures with high viscosity solvents and seals failures etc., also damage of burner lancers. due to corrosion by solvents. Presently the system used as a inertisation of explosive gas mixture in storage tank and tankers. Interlock provided for unloading pump skid with main storage tank pressure to avoid over pressurization during tanker unloading. Pressure relief valve is also provided over the storage tank. During leakages and pressurization of tank there is chance of pungent smell. To arrest heavy leakages MHIPL has made DIKE WALL provision. To control the occasional odour problem MHIPL has installed the odour control system supplied by M/s APZEM which consist of wet and dry scrubber as well as activated carbon. is operating smoothly and consistently. Since it is air assisted burner there is no effect on flame momentum and burning zone temperature . Before unloading the tanker, the solvents are tested for calorific value and compatibility and less than 2500 kcal/kg are 20
