Calculating Raw Materials

Determine a raw material to become new product estimated the raw materials and areas to achieve production target, For example, the manufacture of glucose from corn starch, the pre-design of this plant is the result of my own work to completion of my course in chemical engineering. The first thing we are doing is the analysis of raw materials that we will make the product and the area of raw materials are also easy for transportation. To know the production needs of plants that we design, we have to calculate the production in 5 years ago.

Source : BPSI 2010-2014

From some glucose description data mentioned beside, the magnitude of opportunity be able to increase amount of glucose production, with utilization of corn starch so as to increase development of human and economic resources of the State.

Where: x is the desired year ie 2015

  • X1 is the year 2010
  • X2 is the year 2011
  • Y is the production you want to know
  • Y1 is production in 2010
  • Y2 is production in 2011

From data extrapolation of corn plantation production in Aceh in year 2015 estimated 2,745 ton/year, hence plan of corn starch processing factory with product capacity 12.000 ton / year with requirement of raw material 2,745 ton/year.

Chemical Content Analysis

Knowing the level of chemicals in a raw material, because the core of this raw material to be processed into a product, for example, Corn kernels are rich of carbohydrates. Most are on endospermium. Carbohydrate content can reach 80% of all dry seeds. Carbohydrates in starch form are generally a mixture of amylose and amylopectin. In sticky corn, most or all of its sticks are amylopectin. This difference does not have much effect on nutrient content, but more meaning in processing as food.  Carbohydrate is a carbon, hydrogen and oxygen compound widely found in nature that has the empirical formula CH2O. Generally, carbohydrate sugars are divided into three groups, Monosaccharides, Disaccharide, Polysaccharides. Polysaccharides are composed of many single sugar molecules, most importantly besides disaccharides are cellulase having formulas C12H22O11 and starch (C6H10O5)8

Calculation of Mass Balance

Mass balance calculation aims to knowing of energy needed on each instrument

Calculation of Energy Balance

Enegy balance calculation aims to know the capacity required by the instrument to be operated in the industry.

Designing utilities to find out the capacity of electric current and water required in industrial operations.

Utilities are the main supporting units to facilitate the production process. Therefore, in order for the production process to continue continuously it must be supported by good utility tools and infrastructure. Based on its needs, the utility at the Corn Glucose making plant is as follows:

1. Steam supply unit (steam) 2. Water supply unit 3. Chemical supply unit 4. Unit of fuel provider 5. Electricity supply unit 6. Waste processing unit

Economic Analysis

To evaluate the feasibility of the establishment of a factory and the level of income, the technical calculation is performed. Furthermore, it is also necessary to analyze the economic aspects and financing. From the analysis result, it is expected that various policies can be taken for proper direction. A factory design is deemed feasible to be established if it can operate under favorable conditions.
Various economic parameters are used as a guide to determine whether or not a factory is established and the level of income that is economically acceptable. These parameters include:
1. Capital investment (CI)
2. Total production cost (TC)
3. Profit Margin (PM)
4. Break Even Point (BEP)
5. Return on Return on Investment (ROI)
6. Payback Time (POT)
7. Internal Rate of Return (IRR)
