| dc.description.abstract | Pre-design of a methyl acrylate factory on etherification process with
capacity of60.000 ton/years in the form of liquid, has a purity of 99%.This product
gives very good prospect, considering the requirement of Methyl Acrylate in
Indonesia which progressively increase, industrial users especially are
textile, paper, acrylic fiber industries etc. The main material of Acrylate Acid obtained
from the PT. Trypolyta Indonesia and methanol from PT. KMI Bontang, East
Kalimantan. The factory is planned since atime of establishment of an industrial area
at Cilegon, West Java in 2012.
Methyl acrylate produced by reacting acrylic acid with methanol and sulphate
acid as a catalyst. The reaction happened within a stirred reactor tank. Reactor is
operated continuously in an exothermic temperature 55 °C and pressure at 1 atm. A
comparison between the acrylic acid and methanol used in reaction is 2 : 1. Time of
reaction in the reactors is 1,3 hours. An entire ouput product of the reactor is in the
form of liquid then it is brought to neutralizer to eliminating H2SO4 after that
separated through a Decanter, and purified in a column of Distillation and ready to
market.
Form of the company is an incorporated one with a staff and a line
organization structure. Aworking division for the employees is done according to
working hours comprise shift employees and non-shift employees.
From an economic analysis done by factory it is needed afixed capital as big
as US$ 31,854,348.76; working capital (WC) : US$ 14.231.049.54; BEP- 36 67%
SDP: 14.45% before-tax ROI: 38.05% after tax ROI: 19.02% before-tax POT: 2.08
years, after tax POT: 3.45 years, while before-tax returns: Rpl 15,130,614 596 18 and
after t-tax returns as bigas Rp57,565,307,298.09 | en_US |
