| dc.description.abstract | Cellulose acetate is cellulose whose hydroxyl groups have been replaced by acetyl
groups. Cellulose acetate is a white solid, tasteless, odorless and non-toxic.
Cellulose acetate has high commercial value because it has good physical and
optical characteristics, so it is widely used as a fiber for textiles, cigarette filters,
plastics, photographic films, lacquers, paper coatings and membranes. In addition,
Cellulose acetate has high attractiveness because it is biodegradable so it is
environmentally friendly. The main objective in designing this plant is to
implement the Chemical Engineering discipline and to provide initial information
in designing a cellulose acetate plant from pineapple leaves. pre-design of a plant
for making cellulose acetate form pineapple leaves with a capacity of 12.000
tons/year operates with emil heuser method and operating time for 330 days in one
year. The main process in this pre-design consists of 3 process stages, namely :
pineapple leaves pre-treatment process, delignification process and acetylation
process. In the acetylation stage, a type of reactor is used Continuous Stirred Tank
which operates at a temperature of 40℃ at a pressure of 1 atm for half an hour. The
amount of Pineapple Leaves needed to achieve a cellulose acetate production
capacity of 12,000 tons/year or 1515.152 kg/hour is 2011.563 kg/hour. The plant
for making cellulose acetate from pineapple leaves is planned to be established in
Tulang Bawang Regency, Dente Teladas District, Lampung with a land area of
around 18,300 m2. The water requirement at this plant is supplied form Seputih
river, Tulang Bawang Regency, Lampung as much as 272.448,446 kg/hour. The
planned form of company organization is Perseroan Terbatas (PT) with a line and
staff organizational structure and a total 154 employees. For the establishment an
operation of the plant requires investment capital of IDR 2.143.936.725.824,- and
production costs of IDR 2.056.126.525.148,-. Based on the feasibility analysis, this
plant has a BEP 18,08%, ROI of 26,85%, POT for 3,72 years, RON of 44,75% and
IRR of 33,72%. Based of the result of the economic analysis, it can be concluded
that the “Pre-Design of a Plant for Making Cellulose Acetate form Pineapple Leaves
Using the Emil Heuser Method with a Capacity of 12.000 Tons/Year” is feasible to
be established. | en_US |
