The stack gas contains halogen gasses, metal oxide, some fine particles and other gasses, while the remaining sand are generated as bottom slag after the incineration process is completed. Explain how to handle and manage the bottom slag and treat the halogen gasses generated in the stack gas after the incineration process is completed. Draw a complete process flow diagram illustrating the unit operation(s) required after the incinerator before discharging the emission to the environment and explain the process required.
