Abstract
The Ethylene Dichloride (EDC) plant using the direct chlorination method is designed with a capacity of 98,000 tons/year, to be established in the Krakatau Industrial Estate, Warnasari, Cilegon, Banten. The main raw materials used are Ethylene (C₂H₄) and Chlorine (Cl₂), while the supporting material used as a catalyst is Ethylene Dibromide (C₂H₄Br₂). The production process consists of a raw material preparation stage, namely pressure reduction and heating of ethylene (C₂H₄) and chlorine (Cl₂) to the reaction temperature, after which chlorine (Cl₂) is passed through ethylene dibromide (C₂H₄Br₂) before entering the reactor. The next stage is the chlorination reaction in a chlorinating tower, which produces ethylene dichloride (C₂H₄Cl₂). The reaction product is then cooled and separated in a separator, where the gas phase is recycled back to the reactor while the liquid phase is purified using a distillation column. The final stage is the purification of ethylene dichloride (C₂H₄Cl₂) as the main product and the recovery of ethylene dibromide (C₂H₄Br₂) for reuse as a catalyst, thereby improving process efficiency. The plant's electricity requirements are supplied by PLN for air conditioning and lighting, while process electricity needs are supplied by a generator set. Water requirements are obtained from KTI Cilegon, Banten, which will be processed in the utility unit for use as process water, cooling water, boiler feed water, and sanitation water. This plant adopts a Limited Liability Company (PT) organizational system, with a line-and-staff organizational structure. The plant is planned to operate continuously, with an annual operating time of 330 days of production. Based on the calculations and discussion that have been carried out, the following conclusions can be drawn: Production Capacity : 98,000 tons/year Company Form : Limited Liability Company (PT) Organizational System : Line and Staff Number of Employees : 153 Operating Time : 330 days/year, 24 hours/day Plant Location : Krakatau Industrial Estate, Warnasari, Cilegon, Banten Plant Area : 25,000 m² Raw Materials a.
