Prarancangan Pabrik Linier Alkylbenzene (Lab) Dengan Proses Uop/Cepsa Dengan Disain Alat Utama Reaktor Fixed Bed Multitube

ABSTRACT
Linear Alkyl Benzene (LAB) is one of the organic chemicals in the form of clear
liquids with the formula of mokelul C6H5CnH2n+1. LAB is used as raw material in
detergent industry. LAB is chosen because it has a high rate of degradation so it
is environmentally friendly (biodegradable). In 1995, UOP/CEPSA introduced a
method of creating LAB using solid catalysts, called Detal Process. Due to higher
yields, product quality and lower production costs, this process is considered
better. Lab factory design capacity is 80,000 tons/year with the flow rate of
incoming feeds and products of 4,5243.298 kg/h, in order to meet the needs of
LAB in Indonesia which is 20% still exporting from abroad. One of the main tools
used to produce LAB is a dehydrogenation reactor with a type of fixed bed multitube
that serves to convert di-olefin into mono-olefin. The process is carried out at
a temperature of 450oC and a pressure of 300 kPa (abs) with the help of platinum
catalysts (Pt) in the liquid phase. The conversion rate of the reaction is 18% and
the product is a mixture of mono-olefin, di-olefin, aromatic, hydrogen and
paraffin. The type of reactor used is fixed bed multi-tube with lid and base
elliptical head, and the buffer in the form of skirt support. The reactor is designed
with a height of 9.76 m and a diameter of 6.08 m. In addition, the
dehydrogenation reactor is equipped with steam as its internal heater. The predesigned
economic analysis of this factory obtained a Return On Investment
Percent (%ROI) pf 48.66%, a payback period (PBP) pf 1.7 years, a BEP of 50%
and an IRR of 22.74%. From the results of the economic feasibility analysis
above, it can be concluded that the LAB factory is feasible to build. The
establishment of this factory is also based on advancing the Indonesian economic
sector.
