Polybutylene Succinate Production Process Cost Analysis Pbs E31b PDF Download

This report presents a cost analysis of Polybutylene Succinate (PBS) production from raw sugar and butanediol. The process examined is a combination of a process similar to Myriant process (for producing bio-succinic acid) with a process similar to Uhde Inventa-Fischer process. In this process, raw sugar (sucrose) is diluted and sucrose is hydrolyzed into glucose and fructose (invert sugars). The invert sugars are then fermented to produce Succinic Acid. This step generates ammonium sulfate as by-product. The succinic acid is then combined with butanediol to generate the Polybutylne Succinate. This report was developed based essentially on the following reference(s): (1) US Patent 8778656, issued to Myriant in 2014 (2) US Patent 20150065678, issued to Uhde Inventa-Fischer Gmbh in 2015 (3) US Patent 8604156, issued to Hitachi in 2013 Keywords: Dextrose, Butanedioic Acid, Anaerobic Fermentation, Bio-Succinic Acid, Bio-Butanediol, BDO, 2R Process, Biodegradable Polymer
