Title: Sophisticated new/retrofit cogeneration plant boosts profits

Abstract

Conversion of a coal-capable boiler that produced 200-psig saturated steam for process to a high-pressure unit, the addition of a new coal-fired steam generator, and the installation of two turbine/generators at its Park 500 reconstituted-leaf (tobacco) plant in Chester, Va, have enabled Philip Morris USA to reduce the facility's operating costs while improving availability. The first process line at the plant, and the 120,000-lb/hr (at 200 psig, saturated), oil-fired packaged boiler serving it, were installed in 1974. Purpose: To reprocess into a usable product the stems and other parts of the tobacco leaf that must be removed before cigarette manufacture. The reconstituted-leaf process essentially makes a sheet of pure tobacco ''paper'' using a method similar to that of the kraft process. Reconstituted leaf is mixed with natural leaf in the manufacture of smoking materials. Though it accounts for only a small amount of the tobacco in a typical cigarette, the reprocessed product is an important economic factor, because of the high cost of natural leaf. About the time a second process line and the 200,000-lb/hr coal-fired boiler for it were installed in 1978, oil prices jumped dramatically and the relatively simple, oil/gas-fired, low-pressure industrial steam system-an industry standard since themore » 1950s-became an economic liability. Thus, when planning for a third process line was initiated in 1979, coal firing and cogeneration were foremost in the minds of engineers.« less
