The design, fabrication and erection procedures are discussed for a 170-ft free-standing fiberglass reinforced plastic exhaust stack-scrubber system. Advantages and disadvantages in the use of fiberglass materials for stacks subjected to corrosive environments are presented. Based on a cost comparison study, the system was 30% less expensive than the second most economical option. The design of the stack was accomplished with aid of finite element methods and theory for anisotropic composite materials. A brief discussion is included on those current fiberglass fabrication techniques most suitable for stack construction.
