Question- A No. 5 fuel oil having a maximum sulfur content of 2.0 percent and a heating value of 148,000 Btu/gal is being considered as a fuel for an industrial boiler. If the specific gravity of the oil is 0.953, what is the minimum efficiency required of a sulfur dioxide scrubber system in order for the plant to meet an emission standard of 0.8 lb/106 Btu for a new plant?
I want to know how this is done please show all steps in detail
