Tail Gas Incinerator and Waste Heat Unit

Waste gases contsdning liquids that must be disposed of and that for environmental or safety reasons cannot be directed to the flare system are burned in a tail gas incinerator, shown in Exhibit 7-50. The horizontal in- 

The waste heat recovery unit, illustrated in Exhibit 7-51, uses the waste gases of 800 to 1,200° F (425 to 650° C) from a gas turbine to generate high- and low-pressure steam for plant use. As can be seen in this exhibit, duct burners located in the inlet of this unit can be used if the turbine is shut down, providing a
