description |
Bio-succinic acid (BSA) or 1,4-butanedioic acid is a chemical compound which is
functioned as the main feedstock for plastic manufacturing, bio-degradable plastic
production (Polybutylene succinate or PBS). Bio-succinic acid will reduce the dependency
of fossil-based resources forthe plastic manufacturing. As a chemical compund with two
carboxylic groups,the succinic acid chemical structure that consists of four carbon atoms
in its chain, is similar to the structure of maleic anhydride. Because of their chemical
structure similarity, succinic acid can stand in line with maleic anhydride and the other
chemical platforms to synthesize several chemical products.
BSA Plant is planned to operate for 331 days in a year with production capacity of
10,000 MTPY. The main feedstocks are 22,620 MTPY of molasses and 4,250 MTPY of CO2.
The process of anaerobic fermentation which is supported by A. succinogenes as the biocatalyst,
will be the main process in the synthesizing unit. Generally, the steps of producing
succinic acid are (i) Fermentation process to produce Mg-succinate, (ii) Acidification to
transform Mg-succinate into succinic acid, (iii) Direct crystallization (cooling
crystallization) to crystallize the succinic acid solution, (iv) Crystal drying and size
grouping. As the supporting unit, unit of utility provide steam supply as many as 16.924
ton/year, eletricity need 3.877,12 kW, and water supply 224 m3/hour.
The economic evaluation to analyze the profitability of BSA plant results in the fixed
capital required $ 84.824.082,00. Working capital required is $ 33.155.795,00. Based on
the feasibility studies, the Rate of Return On Investment (ROI) before tax is 23,61% % and
ROI after tax is 17,71%. The Pay Out Time (POT) before tax is 3,04, years and POT after
tax is 5,07 years. The Break Even Point (BEP) is 48,67 % and the Shut Down Point (SDP)
is 20,98 %. The Discounted Cash Flow Rate Of Return (DCFROR) is 30,36 %. The Net
Positive Value of the BSA Plant construction (2 years) and operation (10 years plant�s life)
is $ 74.865.442,00. Based on consideration of the economical evaluation results, the BSA
Plant with capacity of 10,000 MTPY is worth to be studied further. |
