ABSTRACT

The incineration of hydrogen sulfide, however, creates sulfur dioxide or, under conditions of high excess air, sulfur trioxide, both of which are toxic gases and should not be released to the atmosphere in large quantities. Most thermal incineration processes are not particularly concerned with efficiency because they start at a very, very low concentration of hydrocarbons, and even if there is some carbon monoxide left in the flue gas, it is inconsequential. In the incineration of any chlorinated material there will always be minute amounts of free chlorine present because the reaction will never be 100 percent complete. Since the hydrocarbon is usually mixed with air, it is not necessary to add additional air to perform the thermal incineration process. Thermal incineration is a very useful tool for the destruction of a wide variety of waste gases. Typical thermal efficiencies can range from 30 to 90 percent heat recovery, and the resulting fuel savings can be substantial.
