Abstract
Preliminary design of an acetylene plant with a production capacity of 75,000 metric tons per year using calcium carbide (CaC₂) and water (H₂O) as raw materials through a wet hydrolysis process. The plant is planned to be located in the JIIPE Industrial Park, Manyar Subdistrict, Gresik Regency, East Java. The selection of the plant’s location was based on several considerations, including the availability of raw materials, proximity to markets, ease of transportation and distribution, availability of utilities, labor, and environmental factors. The establishment of the acetylene plant is based on domestic demand for acetylene, which is used as a raw material and auxiliary material in various industries; therefore, an increase in domestic production capacity is necessary to meet this demand. The acetylene production process involves the hydrolysis of calcium carbide with water, producing acetylene (C2H2) and calcium hydroxide (Ca(OH)2). The process stages include the storage and preparation of raw materials, feeding calcium carbide into the acetylene generator, hydrolysis with water, separation of acetylene gas from the calcium hydroxide slurry, cooling and condensation, drying, gas purification, compression, and product storage. The acetylene gas produced is then purified to remove impurities such as phosphine (PH3), hydrogen sulfide (H2S), ammonia (NH3), and other impurities before being compressed and stored as the final product. Byproducts, including calcium hydroxide and waste from the purification process, are subsequently handled through a waste treatment unit in accordance with their respective characteristics. Based on the results of the analysis conducted, the establishment of this plant is deemed technically and operationally feasible and has the potential to meet domestic acetylene demand.
