Bio-Butadiene Production from Glucose (Aerobic Fermentation)
Butadiene Operating Costs & Plant Construction Costs
It presents the economics of bio-based 1,3-Butadiene (BD) production from glucose syrup in the United States using a direct aerobic fermentation process similar to the one proposed by Global Bioenergies.
The report provides a comprehensive study of Butadiene production and related Butadiene production cost, covering three key aspects: a complete description of the Butadiene production process examined; an in-depth analysis of the related Butadiene plant capital cost (Capex); and an evaluation of the respective Butadiene plant operating costs (Opex).
The Butadiene production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Butadiene plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Butadiene plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises three major sections: (1) Fermentation; (2) Fermentation broth treatment; and (3) Butadiene purification.
Fermentation. The culture media is prepared by diluting the glucose syrup and nutrients in water. A genetically re-engineered yeast is propagated in an aerobic pre-fermentation step to obtain the proper inoculum concentration. The fermentation is carried out in fed-batch mode and under aerobic process conditions, in agitated fermenters equipped with internal coil. The fermentation step generates fermenter off-gas, which comprises the crude Butadiene product, and fermentation broth.
Fermentation broth treatment. After fermentation, cell biomass is separated from the fermentation broth. The clarified broth then is submitted to an ultrafiltration step, used to remove the remaining contaminants. The resulting aqueous stream may be discarded as waste water.
Butadiene purification. Initially, off-gas is compressed and cooled. The compressed gas is fed in a absorber column, where N-dodecane solvent absorbs the Butadiene. In the next column, In the Stripper Column, Butadiene is separated from the solvent. The recovered solvent is fed into a decanter for water removal before being recycled to first column. The Butadiene-containing stream is transferred into the Adsorption System. There, The oxygenates are removed by adsorption in adequate media. The oxygenate-free crude Butadiene is further purified in a last distillation column for heavy ends impurities separation. Butadiene with purity >99.7 wt% is recovered.

Butadiene Production from Butenes
This study presents the economics of 1,3-Butadiene (BD) production from mixed butenes in a plant assumed to be erected in the United States. In this process, which is similar to TPC/UOP Oxo-D, butenes are catalytically dehydrogenated to produce the Butadiene product. Raffinate is obtained as by-product.

Butadiene Production from Ethanol
This report examines the costs related to 1,3-Butadiene (BD) production from hydrous ethanol in the United States. This process consists of a two-stage reaction process. First, ethanol is converted to acetaldehyde, which is then reacted with ethanol to produce 1,3-Butadiene. Raffinate is generated as by-product in the process.

Emulsion Styrene Butadiene Rubber Production
This report presents the economics of SBR production starting from butadiene and styrene. The analysis encompasses a plant located in the United States, employing a typical cold emulsion process for generating a non-oil extended, non-staining grade of emulsion SBR (similar to 1502). In this process, an emulsion comprising water, styrene and butadiene is polymerized into a latex, which is then coagulated to form the SBR.

Polychloroprene Production from Butadiene and Chlorine
This study provides an economic analysis of Polychloroprene production starting from butadiene and chlorine, based on a plant located in the United States. In the first step, butadiene is chlorinated, generating dichlorobutenes, which are subjected to an isomerization to convert them to 3,4-dichloro-1-butene. It is then dehydrochlorinated, forming chloroprene. Finally, chloroprene is polymerized to the respective rubber.
