Value Added Downstream Products to Improve Profitability

8 Value Added Downstream Products to Improve Profitability 

Since profits from sulfuric acid plants have reduced for a variety of factors, it is necessary to explore possibilities of diversifying the operations for value-added downstream products. Some of these have already been indicated in the chapter on economic considerations. 

Efforts have been made to address some of the areas as outlined above in the technology available from the authors, which are as follows  

A sulfur filter and two centrifugal pumps are provided for filtering the raw sulfur. Metering pumps are provided to ensure a steady sulfur feed to the burner. This will help in maintaining steady process conditions, very essential for efficient plant operations. 

The sulfur burner should be lined with insulating bricks and high alumina and very high alumina (60-65%) fire bricks to conserve heat inside and to enable operation of the plant at 10.5-11.0% 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.
