ABSTRACT
Alpha olefins are straight-chain hydrocarbons with double bonds in the alpha position, namely
1-butene, 1-hexene, and 1-octene. Alpha olefins production is classified as a basic chemical product
because it is used as a raw material for chemical production. Alpha olefins in Indonesia are used as
commonomers for the production of Linear Low Density Polyethylene (LLDPE) and High Density
Polyethylene (HDPE). LLDPE production requires 10% alpha olefins comonomer (C4-C8) and
HDPE requires 4% Alpha Olefins comonomer (C4-C6). The need for alpha olefins in Indonesia is
currently met by imports because alpha olefins are not produced domestically. The establishment of
an alpha olefins factory will reduce the need for imports and increase state revenues. The alpha olefins
factory was established in Ciwandan District, Cilegon City, Banten Province in 2024 with a
production capacity of 58,000 tons/year.
The process used to produce alpha olefins is the ethylene oligomerization reaction using toluene
solvent and zirconium (IV) silicate (ZrSiO4) catalyst and trimethylaluminum (Al(CH3)3) co-catalyst.
The reaction takes place at operating conditions of 80°C temperature and 30 bar pressure, producing
the main alpha olefins products are 1-butene, 1-hexene and 1-octene. The electricity needs of the plant
are met by a turbine driven by steam. Water needs are obtained through river water purification with
the principle of coagulation and flocculation. Liquid waste from laboratory waste, maintenance
waste, and domestic waste is processed through tertiary treatment, namely the filtration process,
activated sludge and chemical processing. B3 waste from deactivated catalyst is managed by a third
party, namely PT. Krakatau Steel WWTP. The plant is designed by implementing a heat exchanger
network (HEN). The equipment in the plant is equipped with safety instruments and process control
instruments to ensure process performance, ensure stability and suppress external disturbances. The
main equipment designed is an ethylene oligomerization reactor that functions to react ethylene
monomers to form ethylene oligomers such as 1-butene, 1-hexene, and 1-octene.
The alpha olefins factory has a working time of 347 days per year and 24 hours per day. The
factory operates for 47 weeks/year and 3 weeks/year are used for shut down, maintenance, and
repairs. The form of the company is a Limited Liability Company (PT) which uses a fungtional
organizational system with 131 employees. Based on the results of the economic analysis, the alpha
olefins factory is feasible to be built with a Discounted Payback Period of 4.78 years, an Internal
Rate of Return of 24.29%, a Break Even Point of 35.36%, and a Net Present Value of
Rp10,006,357,284,476.
