| dc.description.abstract | The pre-designed plant for making linear alkylbenzene sulfonate from alkylbenzene using the sulfonation process has a production capacity of 1,200 tons/year and operates for 330 days a year. The main process in the pre-plant design consists of three stages, namely the raw material preparation stage, the sulfonation and neutralization reaction stage, and the purification stage. In the sulfonation and neutralization stages, 2 continuous stirred tank reactor units were used which operated at a temperature of 55°C for 1 hour. The amount of alkylbenzene required to reach annual production capacity is 108.1442 kg/hour.
The specific task completed was the detailed engineering design of the reactor for the sulfonation process. The reactor that has been designed has the following specifications:
• Number of Reactors: 1 unit
• Tank shell height: 1.016 m
• Tank head height: 0.169 m
• Reactor shell material: Carbon steel SA-285 grade C
• Konis height: 0.111 m
• Total tank height: 1,589 m
• Reactor shell thickness: 3/16 in
• Reactor head thickness: 3/16 in
• Stirrer diameter: 0.204 m
• Stirrer distance: 0.204 m
• Blade width: 0.041 m
• Bulkhead width: 0.051 m
• Blade length: 0.051 m
• Jacket diameter: 0.876 m
• Jacket height: 0.892 m
• Area traversed: 0.299 m
• Jacket thickness: 3/16 in
The factory for making linear alkylbenzene sulfonate from alkylbenzene using the sulfonation process is planned to be established in Sunggal District, Deli Serdang Regency, North Sumatra Province, with a total factory area of 4,900 m2. The water requirement at this factory is supplied from the Deli River as much as 51,242,409 kg/hour. The planned form of company organization is a Limited Liability Company (PT) with a line organizational structure, and a total of 123 employees.
The results of the economic analysis on the pre-design of this factory are as follows:
1. Capital Investment (CI): IDR 90,502,363,451
2. Total Cost (TC): IDR 49,733,566,945
3. Profit Margin (PM): 43.41 %
4. Break Even Point (BEP): 42.11%
5. Return On Investment (ROI): 30.81%
6. Pay Out Time (POT): 3 years 2 months
7. Return On Network (RON): 51.35%
8. Internal Rate of Return (IRR): 26.42%
Based on the results of the economic analysis, it can be concluded that a linear alkylbenzene sulfonate manufacturing plant from alkylbenzene using the sulfonation process is feasible to be established | en_US |
