Example text
Higher strengths of oleum are not very corrosive to steel as compared to weaker 18–20% oleums. This property is taken into consideration when designing and constructing the oleum tower, piping, oleum boiler, heat exchangers, etc. ) It is also found that, rather than a separate circulation tank for the oleum, an extension of the lower boot of the oleum tower with a submerged type circulation pump is safer and easier to operate. Appropriate sealing at the pump base frame prevents any escape of acidic vapors from the tank.
Cost of accessories: capital and running cost for cooling tower water pumps, water treatment plant, etc. 11. Typical factors related to sulfuric acid oleum plants which affect cogeneration of power: • Waste heat recovery units installed and design of individual units. • Plant production rate and plant operating conditions. • Catalyst activity in individual passes. • Performance of all heat exchangers. • Design of existing electrical system. • Electrical motors connected to each drive and their operating loads.
A level controller is provided to maintain the tank level in the circulation boot. The product from the continuous plant manufacturing 65% oleum is sent to storage for dispatch to the consumers in tankers of capacity 10–20 tonnes. Fig. 1 Freezing point of H2SO4, oleum, and SO3 38 4 Sulfonating Agents and Derivatives Based on Sulfuric Acid The 65% oleum is transported in SS-316L tankers instead of MS when the iron content in the product is to be kept low. 3 Uses The demand for 65% oleum is primarily for the manufacture of special dyes and intermediates such as H-acid.
