		abstract={This 1.3-Butadiene manufacturing plant with a capacity of 60,000 tons / year is planned to be established in 2024 in the Krakatau Steel Industrial Zone, Cilegon City, Banten Province with an area of ​​5.2 hectares. The process of making 1,3-Butadiene is a dehydration process of 2,3-Butanediol using a calcium phosphate hydroxyapatite catalyst in a multitube fixed bed reactor of 4 pieces. The reactor has operating conditions at the same temperature that is 365oC, while the sequential pressure is 2.2; 1.85; 1,5; and 1.21 bar, with the following reaction.
C4H10O2 (g)  C4H8O (g) + H2O (g)
2,3-Butanadiol 3-Buten-2-Ol Water
C4H8O (g)  C4H6 (g) + H2O (g)
3-Buten-2-Ol 1,3-Butadiene Water
C4H10O2 (g)  C4H8O (g) + H2O (g)
2,3-Butanadiol Methyl Ethyl Ketone Water
C4H10O2 (g)  C4H8O (g) + H2O (g)
2,3-Butanadiol 2-Methyl Propanal Water
This plant is a type of Limited Liability Company (PT) with line and staff organization system and the number of employees is 152 people. Based on the results of an economic analysis, a 1,3-Butadiene manufacturing plant is worth setting up with the following details.
a. Investment = US $ 115,973,048.01
b. Sales revenue per year = US $ 400,863,511.66
c. Cost of production per year = US $ 342,533,473.14
d. Net profit per year = US $ 52,181,932.38
e. Pay out time = 2.1 years
f. Rate of return on investment = 37.72%
g. Discounted cash flow = 55.82%
h. Break even point = 34.17%
i. Service life = 11 years}
