Changes in the demand for products, and changes in the feedstock drive constant development.
The model is flexible in that it can be modified to calculate the effects on capital and production costs of changes in feedstock cost, changes in the type of feedstock employed, changes in the value of the glycerol coproduct, and changes in process chemistry and technology.
Recent changes in the availability of feedstocks, including renewables and tight oils, and longer-term trends in the demand for propylene, gasoline, and middle distillates require further developments in both catalyst and process.
The sensitivity of the MBSP to changes in the prices of feedstock and of products has been examined by changing one price at a time from -50% to +50%.
However, due to changes in quality, nature of the crude oil feedstock, changes in the environment and the desire to achieve maximum profitability, it results in many different operating conditions in the FCC riser unit [5, 9].
Reported technologies, listed from highest to lowest anticipated mercury removal, include purge of collected dust or raw meal, changes in feedstocks and fuels, wet scrubbing, cleaning of mercury enriched dust, dry sorbent injection, and dry and semi-dry scrubbing.
Variation of the catalyst metal (iron, nickel, cobalt) and in the feedstock gas (acetylene, methane) did not result in any significant changes in the NT/NFs structure.
In this study we evaluated changes in the metatranscriptomic profiles of the R. flavipes gut microenvironment in response to feeding on two second generation feedstocks (corn stover [CS] and soybean hull residue [SR]).
This model used simplified descriptions of LE conversion processes, together with emission factor estimates for feedstocks and supply chain operations, to determine the sensitivity of GHG emissions estimates to changes in the supply chain.
This model uses simplified descriptions of LE conversion processes, together with feedstock and ethanol price estimates and finance scenarios, to determine the sensitivity of the production cost to changes in the supply-chain.
This approach is cost and labor intensive as a new set of experiment has to be conducted every time sugar composition in the feedstock changes.
