It is interesting to note that, apart from the increase in demand, the capacity utilization of CSA will depend on its location, materials of construction, and technology. Hence, the existing plant may not be running with full capacity utilization. It is interesting to note that on 70% utilization there is a gap of almost 8,000 tonnes of CSA. This has resulted in the price rising from Rs. 3,500/tonne to Rs. 5,000/tonne during shortage. 5 Diethyl Sulfate Diethyl sulfate (DES) is a highly toxic chemical compound with formula (C2H5)2SO4.
The process steps – burning sulfur, roasting sulfide ores, SO2 conversion, and SO3 absorption – are exothermic processes. This means that, from a technical point of view, installations for removing energy are of great importance for the production of sulfuric acid. This is coupled most effectively with energy winning in different levels and forms. Energy winning is dependent on the process strategy for the target products, for the local conditions, and for a possible relationship to other production processes.
In the DCDA process, the candle type demister developed by Monsanto (USA) was the major breakthrough. 99% of mist above 1 μm. Any mist carryover would hurt not only the heat exchangers but would also affect the catalyst activity in the converter passes 4 and 5. 4 Wet Contact Process (WCP) This process is not sensitive to the water balance and has been used to treat off-gas from a molybdenum smelter as well as being installed in two desulfurization plants (one in a flue gas desulfurization system, the other on an industrial boiler) currently under construction.
