Book Description
This report presents a cost analysis of Polylactic Acid (PLA) production starting from corn The first section of the examined process is similar to Cargill process for lactic acid production, while the second section is similar to the NatureWorks process for polymerization of lactic acid. In this process, shelled corn is passed through a wet milling process to form corn starch, which, in turn, is hydrolyzed to dextrose, the feed for the fermentation process that generates lactic acid . Lactic Acid recovery from the fermentation broth is carried out via trialkylamine solvent extraction in the presence of carbon dioxide. A L-Lactic Acid solution in water is formed and further polymerized to form Polylactic Acid. The conversion of corn into dextrose forms some residues that are sold as by-product. This report was developed based essentially on the following reference(s): (1) US Patent 6472559, issued to Cargill in 2002 (2) US Patent 8674056, issued to NatureWorks in 2014 (3) EP Patent 1247808, issued to Cargill in 2003 Keywords: Corn, Corn Starch, 2-Hydroxypropanoic Acid, Anaerobic Fermentation, Trialkyl Amine, Sodium Carbonate, Lactide, 2-Hydroxypropanoic Acid, Dow, Biodegradable Polymer

Book Description
This report presents a cost analysis of Hydrous Ethanol production from corn. The process examined is a typical dry milling process. In the process examined, corn is ground, slurried with water and then submitted to enzymatic hydrolysis, which convert starch to glucose. Next, the glucose is fermented to Ethanol by yeasts, and the fermentation product is fed to a distillation system, yielding Hydrous Ethanol. The non-fermented material recovered is passed through centrifugation, evaporation and drying steps to produce Distiller's Dried Grain with Solubles (DDGS) as by-product. This report was developed based essentially on the following reference(s): (1) "Ethanol," Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) "Ethanol Processing," Occupational Safety and Health Administration (OSHA), Instruction TED 01-00-015 Keywords: Ethyl Alcohol, Bioethanol, Biomass, DDG, Dry Mill, Shelled Corn

Book Description
This report presents a cost analysis of Renewable Diesel production from corn stover. In this process, corn stover is pretreated and its components are hydrolyzed. The hydrolysate is catalytic converted to Diesel product. Naphtha is generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Hydrogenation, Green Diesel, Hydrogen, Hydrotreatment

Book Description
This report presents a cost analysis of Citric Acid production from corn The process examined is a typical fermentation process. In this process, corn starch is hydrolyzed to fermentable sugars, which are converted to Citric Acid. This report was developed based essentially on the following reference(s): (1) 'Citric Acid', Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition (2) Wu, J. et al. 2009 'Model-Based Design of a ilot Scale Simulated Moving Bed for Purification of Citric Acid from Fermentation Broth' Keywords: Hydrolysis, Glucose, Dextrose, Amylase

Book Description
This report presents a cost analysis of Starch-Graft Sodium Polyacrylate production from corn and glacial acrylic acid. In this process, acrylic acid is grafted into corn starch forming a polyacrylate, which is then saponificated with sodium hydroxide. This report was developed based essentially on the following reference(s): Keywords: Superabsorbent Polymer, SAP, Starch-Grafted, NaOH, Slush Powder, Saponification
