FIELD ERECTION OF LARGE FERMENTERS FOR DOW CHEMICAL

ENERFAB has again proven their experience in the design, shop
fabrication, and field erection of large fermenters for pharmaceutical and chemical processing facilities. This time the project involved several large half-pipe jacketed, stainless steel vessels for Dow Chemical, Harbor Beach, MI. Design improvements for the field constructed ASME pressure vessels, equipped to handle a state-of-the-art agitator, not only ensured efficient construction techniques but also operation reliability.

Prefabrication and testing of the large shell and head sections, internal coils and exterior half-pipe jackets, under ideal shop conditions, considerably reduced the time required to erect the tanks in the field. This allowed for a flexible erection sequence which resulted in completion of the first fermenter, including piping, on schedule. Using larger fermenters reduces the cost/gallon of capital expense, and also provides operational advantages when compared to using smaller shop-built fermenters.
