Making Ethylene Dichloride from Ethylene and Chlorine with the Direct Chlorination Method: A Feasibility Study

Introduction

The production of ethylene dichloride (EDC) from ethylene and chlorine using the direct chlorination method is a significant process in the chemical industry. This method involves the reaction of ethylene with chlorine to produce EDC, which is a key raw material in the production of various chemicals, including vinyl chloride monomer (VCM) and polyvinyl chloride (PVC). In this study, we will discuss the feasibility of establishing a factory with a production capacity of 20,000 tons per year using the direct chlorination method.

The Importance of Ethylene Dichloride

Ethylene dichloride is a highly versatile chemical that has a wide range of applications in various industries, including the production of plastics, adhesives, and pharmaceuticals. The demand for EDC is increasing rapidly due to the growing demand for PVC and other related products. Therefore, the production of EDC is a critical process that requires careful planning and execution.

The Direct Chlorination Method

The direct chlorination method is a widely used process for the production of EDC. This method involves the reaction of ethylene with chlorine in the presence of a catalyst to produce EDC. The reaction is highly exothermic, and the temperature and pressure conditions must be carefully controlled to ensure efficient and safe operation.

Factory Design and Capacity

The factory is designed to produce EDC from ethylene and chlorine using the direct chlorination method. The production capacity of the factory is 20,000 tons per year, which is expected to meet the growing demand for EDC in the region. The factory will operate for 330 days a year, and to reach this annual capacity, it takes 811,456 kg of ethylene per hour and chlorine around 2,051,060 kg per hour.

Absorber Design

One of the critical components of the factory is the absorber, which serves to improve the efficiency of the production process. The absorber is designed to optimize the absorption process that occurs between ethylene and chlorine, producing high-quality EDC. The absorber is a packed tower with a diameter of 13 inches, a length of 31.25 feet, and the thickness of the wall 0.013 inches. This design is expected to provide efficient and effective absorption of ethylene and chlorine, resulting in high-quality EDC.

Location and Infrastructure

The factory is planned to be built in the city of Cilegon, Banten Province, with a total area of the factory reaching 11,710 m². This location is chosen due to its proximity to the raw materials and transportation infrastructure. The factory also requires water supply from the Kali Berung River as much as 23,168 kg per hour to support operational activities.

Economic Analysis

The results of the economic analysis show that this factory is worthy of being established. Some important points of the analysis are as follows:

Initial Investment (Capital Investment): Rp. 1,058,015,420.201
Total Costs (Total Cost): Rp. 503,269,630,354
