Bio-Based Succinic Acid Manufacture
Succinic acid is an important industrial chemical that is traditionally derived from petroleum feedstocks. It can be used in several areas — from high-value niche applications, such as food, beverages and pharmaceuticals, to large-volume applications, such as plasticizers, resins and coatings. However, the current market for succinic acid is limited to specialized areas because of its costly production process.
Bio-based succinic acid, produced from renewable feedstocks, appears to be an alternative to the petroleum-derived chemical and may have advantages surrounding concerns about rising atmospheric greenhouse gas (GHG) concentrations and volatile crude oil prices. Bio-succinic acid is chemically equivalent to conventionally produced succinic acid, and is suitable for the same applications.
In the process depicted in the figure below, succinic acid is obtained via microbial fermentation of glucose from sugarcane juice. The process steps and equipment were compiled based on publically available information from the scientific literature.
The sugar consumed in this fermentation-based process is glucose. It is obtained by the inversion of sucrose through its hydrolysis to glucose and fructose. This is achieved by subjecting the juice containing sucrose to an acidic medium by addition of hydrochloric acid (HCl). After inversion, the pH is adjusted with sodium carbonate (Na2CO3) and the stream is cooled before being sent to the fermentation step.
Glucose is converted to succinic acid through an anaerobic fermentation supplied with carbon dioxide. The microorganism culture is ...

An economic evaluation of the bio-based succinic acid process was conducted. The following assumptions were taken into consideration:
- A 77,000 ton/yr unit erected on the U.S. Gulf Coast (the process equipment is represented in the simplifi ed flowsheet)
- Storage of product is equal to 30 days of operation, and there is no storage for feedstock
- Outside battery limits (OSBL) units considered: steam boilers, cooling towers and ammonium refrigeration system
The estimated capital investment (including total fixed investment, working capital and other capital expenses) is ...
