PRA DESIGN OF THE FACTORY MAKING OKSALAL ACID MAKING COCOA SKIN THROUGH THE PROCESS OF ALKALI SEETING WITH CAPACITY OF 3,550 TON/YEAR AND SPECIAL TASK DESIGN DESIGNESS

Introduction

The production of oxalic acid from cocoa skin is a promising industry that can contribute to the economic growth of Indonesia. With the increasing demand for oxalic acid in various industries, the need for a reliable and efficient production process has become a pressing issue. This article presents a pre-design of a factory that produces oxalic acid from cocoa skin through the process of alkaline smelting, with a capacity of 3,550 tons per year.

Background

Cocoa skin is a waste product from the cocoa industry, which is one of the leading commodities in Indonesia. The production of oxalic acid from cocoa skin has the potential to reduce the impact of waste from the cocoa industry and produce high economic value products that are beneficial to the local and national economy. Oxalic acid is a compound in the carboxylic group that has various applications in industries such as textiles, leather, and food.

Production Process

The production process of oxalic acid from cocoa skin involves several stages, including:

Alkaline Smelting Process: This process involves the reaction of cocoa skin with an alkaline substance to produce oxalic acid.
Separation Process I: This process involves the separation of oxalic acid from the reaction mixture.
Acidification Process: This process involves the acidification of oxalic acid to produce a concentrated solution.
Separation Process II: This process involves the separation of oxalic acid from the concentrated solution.
Evaporation Process: This process involves the evaporation of water from the concentrated solution to produce a crystalline product.
Crystallization Process: This process involves the crystallization of oxalic acid from the concentrated solution.
Separation Process III: This process involves the separation of oxalic acid from the crystalline product.

Factory Location and Layout

The factory will be built in Lambale Village, West Kulisusu District, North Buton Regency, Southeast Sulawesi, with a total land area of 11,600 m². The factory will operate for 330 days a year, with 24-hour operating hours every day.

Evaporator Engineering Design

One of the special tasks in this project is to design in detail the evaporator that will be used in the production process. The specifications of the evaporator are as follows:

Evaporator Diameter (D): 2.74 m
Evaporator Height (H): 4.11 m
Evaporator Volume (V): 27.518 m³
Thickness (T): 0.25 inch
Number of Tubes (NT): 10,195 pieces
Hot Transfer Area (A): 1,794 m²

Economic Analysis

Through economic analysis conducted, obtained various financial parameters that show that this factory is worthy of being established:

Total Investment Capital: IDR 493,601,981,359
Total Production Costs: IDR 611,697,687,952
Sales Revenue: IDR 1,295,722,496,000
Net Profit: IDR 476,478,278,805
Profit Margin (PM): 52.53%
Break Even Point (BEP): 42.45%
Return on Investment (ROI): 47.30%
Pay Out Time: 2.11 years
Internal Rate of Return (IRR): 28.53%

Conclusion

From the analysis conducted, it can be concluded that the pre-design of the oxalic acid manufacturing factory from cocoa skin with a capacity of 3,550 tons per year is feasible to be established. By utilizing cocoa leather waste, this factory does not only have the potential to reduce the impact of waste from the cocoa industry, but also produces high economic value products that are beneficial to the local and national economy. Innovations in this process can increase industrial efficiency and make a significant contribution to Indonesia's economic resilience.
