Prarencana pabrik komposit cellulose acetate-organo bentonite

Composite of cellulose acetate-cta-bentonite is made based on the expensive price of membranes that is used mostly by Industries in Indonesia, so that the purpose of this company is to supply the need of membranes in Indonesia, and also in the world. The raw material, which is needed for this company is bought for other country, because of the minimal amount in this country. The membranes that is made is used especially in desalination process which can be seen that the amount of sea water in Indonesia is too much. In the cellulose acetate-cta-bentonite composite preliminary plant design, the method which is used is phase invertion. This type is choosed because of the simple pocess with good quality. Besides that, this process is commonly used to make composite material. The following details of biomethanol preliminary plant-design from oil palm solid waste biomass : Raw Material : bentonite, cellulose acetate, and CTAB surfactant Production Capacity : 382.265,8 kg/years Utilities : Water = 4.3 m3/day : Electricity = 322,4167 kW/days Number of Workers : 70 people Plant Location : Ponorogo, Jawa Timur Province Economic Analysis Rate of Return Investment before tax : 49.28% Rate of Return Investment after tax : 38.31% Pay Out Time before tax : 2 years 9 months Pay Out Time after tax : 3 years 4 months Break Even Point (BEP) : 22.96% Cellulose acetate-cta-bentonite composite preliminary plant design feasibility can be viewed from various aspects, in terms of process, equipment, location, and economics. With a view of various aspects especially in terms of economy, where the Rate of Return Investment (ROR) after tax is greater than the loan interest by 38.68% while the loan interest must be paid is 10%. So that the plant gain is greater than the loan interest payable to the bank
