Rancangan Pabrik Acrolein Dengan Glycerol Dehydration Process Dengan Desain Alat Utama Reaktor Gliserolisis (R-100)

ABSTRACT
The increasing demand for basic chemicals has prompted Indonesia to produce its own
chemicals, which until now have been imported. One example is acrolein, which according to
data from the Central Statistics Agency (2023), Indonesia still imports around 2.098.592
kg/year. Acrolein is the simplest unsaturated aldehyde (C₃H₄O) that plays an important role as
a raw material for various chemical products. To reduce import dependency, it is necessary to
develop the domestic acrolein industry by utilizing glycerol, a major by-product of the biofuel
and oleochemical industries, as an alternative raw material. Acrolein products have a broad
domestic and international market, mainly used in the manufacture of acrylic acid, herbicides,
fungicides, methionine, and glutaraldehyde. The city of Dumai, Riau Province, is a strategic
location for the establishment of a factory because it has many supporting biodiesel industries, is
close to the domestic market, and is located on an international trade route that facilitates access
to global markets.
The acrolein production technology used is the dehydration of glycerol with prior
purification of crude glycerol. The crude glycerol purification process uses a bubble column
reactor that operates at a temperature of 153°C under atmospheric pressure. The glycerol
dehydration reaction produces by-products in the form of methanol, acetaldehyde,
formaldehyde, and acetol. The main product, acrolein, is separated using a T-108 distillation
column. The total electricity requirement for the integrated acrolein plant design is 23.621 kW
with a steam supply system designed using a cogeneration model. Environmental aspects are
taken into consideration by treating the generated waste in accordance with the Regulation of
the Minister of Environment No. 5 of 2014. Each process tool is equipped with a control system
so that the production process achieves the minimum level of error, thereby optimizing product
yield and maintaining occupational health and safety.
The economic analysis of the plant shows positive results. Several parameters of the plant
feasibility analysis and the values obtained are Net Present Value (NPV) of IDR
8.374.038.705.917; Internal Rate of Return (IRR) of 18,66%; Break-Even Point (BEP) of
31,59%; Return on Investment (ROI) of 20,80%; and Payback Period (PBP) during 3,41 year.
A PBP value of less than four years indicates that this investment has a relatively short payback
period, while an IRR higher than the average loan interest rate confirms that this glycerol
dehydration-based acrolein factory is feasible and has the potential to be profitable.
