| Summary: | Acrolein is an intermediate product to produce other products, such as
acrylic acid, methionine, methinine hidroxy, guraldehyde and synthetic amino.
The needs of acrolein and acrylic acid have been fulfilled by importing from other
countries. Development of acrolein in Indonesia is hoped to bring profits and
increase national economic.
The plant is planned to operate for 330 days/year with acrolein production
capacity of 30.000 tons/year. The main raw material required is as much as
34.062,8 tons/year. The main method process used in producing acrolein are
propylene oxidation with oxygen.
In general, acrolein manufacturing stages process are as follows : (i)
propylene oxidation with oxygen in fixed bed multitube reactor with bymuth
molybdate as catalyst. (ii) absorption of acrolein and acetaldehyde from residual
gas reaction using water as a solution, (iii) separatioin of acetaldehyde from
acrolein and water in distillation column � 01, (iv) separation of 99% acrolein
from water as a product in distillation column � 02.
As a support, utility plant unit supplies 274.815 kg/hour of water, 8.778 kW
electricity, compressed air up to 23,75 m3/hour, and 17.114 kg/hour of steam.
The plant will be established in the city of Cilegon, Banten province, with
consideration of raw material oriented. Cilegon region is near PT Chandra Asri
as a propylene producer.
Economic evaluation calculation results the requirement of fixed capital
investment is up to $ 55,522,234 + Rp117.528.524.600 and working capital is up
to $1,628,424 + Rp260.456.919.800. At 100% production, has been obtaned
values of ROI before tax is at 29,28% and ROI after tax is at 17,57%. POT before
tax is 2,58 years, and POT after tax is 3,69 years. BEP at 40,51 %, SDP at 17,09
% and DCFRR at 23,85%. Based on economic evaluation results, plant of
acrolein with producation capacity of 30.000 tons/year are worth it to be studied further. |
