Bioprocessing encompasses a spectrum of techniques, with some involving aerobic fermentation, while others are centered around anaerobic processes for the production of ethanol and chemicals from starches and lignocellulosic materials. Aerobic fermentation stands as a metabolic process wherein cells metabolize sugars through fermentation in the presence of oxygen, effectively suppressing normal respiratory metabolism. This form of fermentation takes place when oxygen is available, typically at the initial stages of the fermentation process. It is characterized by its brevity and heightened intensity compared to anaerobic fermentation. The significance of aerobic fermentation extends across various industries, leading to the selective cultivation of several yeast strains crucial for these processes.
Fermentation itself encompasses diverse process steps and requires an array of equipment. These steps encompass media preparation, which involves equipment like blending tanks, agitators, and heat exchangers; propagation managed through agitators and various vessels; production fermenters, which rely on vessels, agitators, and both internal and external heat exchangers; separations, which employ equipment such as evaporators, centrifuges, distillation apparatus, and membrane/ultra-filtration systems; purification, entailing crystallizers, heat exchangers, and ultra-filtration techniques; and finally, product packaging, which entails considerations like bulk containers (totes), packing lines, and related logistics.
For lignocellulosic and starch-based fuels and chemicals, the production process is equally multifaceted, involving various stages and specialized equipment. This includes material preparation, where conveying equipment, screening equipment, particle size reduction equipment, and air classifying equipment are utilized. Hydrolysis follows, necessitating equipment such as pretreatment tanks, agitators, heat exchangers, hydrolysis reactor tanks, agitators, saccharification processes, and fermentation tanks with associated agitators. Separation steps involve the use of screw presses, filtration systems, centrifuges, distillation setups, and pressure swing absorption techniques. Additionally, co-product preparation entails filtration, drying equipment, conveying machinery, and packaging equipment, including bulk bags and rail car loaders. These comprehensive processes and associated equipment are integral to the production of lignocellulosic and starch-based fuels and chemicals.
