4 Safety Issues A dangerous situation can arise in the case of a sudden power failure or stoppage of the oleum feed pump as oleum can drain back into the tower boot and overflow from there. A non-return valve in the oleum feed line can prevent such incidents. In the case of a tube leak, liquid oleum will enter gas ducts and can drain automatically and safely through a seal pot on the ground floor. A sudden increase of SO3 mist in the stack gases can indicate such a leak, warning the plant operators.
A large plant of up to 200 TPD capacity is feasible with this process. It may be of interest to the reader that India is today producing the maximum output of chloro sulphonic acid in the world. 2 Detailed Account of Sulfonating Agents 41 In India the first commercial production started with a 100 TPY plant in the early 1960s. Nevertheless, the production rapidly increased to 1,500 TPY by the late 1960s. During the 1970s the production and consumption kept up with an annual growth rate of 10%.
Metering pumps are provided to ensure steady sulfur feed to the burner. This helps in maintaining steady process conditions, very essential for efficient plant operations. 5% SO2 in the burner outlet gases. This will reduce the total volume of the gases handled and in turn will reduce the power consumption per MT of acid produced. 5%) of SO2 the furnace shell is air-cooled by the incoming air, which is then sent to the burner. In certain designs the furnace shell is cooled by a separate air blower and the hot air generated is used elsewhere in the premises.
