Biomass derived product, steady-state

Biomass recycle as sketched in Figure 30.4D is frequently used in fermentors as a way of increasing the biomass productivity. The increased biomass productivity obtained with a recycle fermentor is a function of the recycle ratio, r, and the cell concentration factor, C = XJX, achieved in the concentrator. Equations expressing the recycle system behavior are derived from material balances around the reactor. For the cell biomass balance at steady state ... 

The basic steps followed in the product penetration assessment are presented in Figure II. This procedure first entails a static economic analysis based on the competition between the biomass-derived product price and the market price. The resuit is a steady-state market share, reflecting a situation that would be expected to exist after a period during which the competitive economic forces remained constant. Steady-state conditions do not hold soon after the introduction of a new, cost-competitive mission, technology, or product. The marketplace will be in a state of flux as the newcomer gains wider recognition and acceptance. 

Steady-State Market Share to Biomass-Derived Product —... 

Steady-state market share — The fraction of the product market that a biomass-derived product would supply at a point long after the biomass product production price and market price had become unchanging with time.
