Prarancangan Pabrik Heksametilendiamina dari Adiponitril dan Hidrogen Menggunakan Pelarut Etanol dengan Penambahan Proses Recycle Heksametilendiamina Kapasitas 10.000 Ton/Tahun

Abstract

Hexamethylenediamine (HMDA) is a monomer compound in the synthesis of nylon 6,6, produced through the hydrogenation process of adiponitrile with the aid of a Raney nickel catalyst. The primary objective of this plant design is to apply knowledge and chemical engineering discipline in industrial design by considering production, economic, and management aspects, as well as to provide an overview of the feasibility of establishing a hexamethylenediamine plant in Indonesia. This preliminary design is for a plant producing hexamethylenediamine from adiponitrile using a hydrogenation reaction with hydrogen, for a production capacity of 10,000 tons per year. The main process in this plant design consists of three stages: the preparation of raw materials and auxiliary materials, the reaction stage for the formation of hexamethylenediamine, and the product purification stage. This hexamethylenediamine plant from adiponitrile and hydrogen is planned to be established in the Krakatau Industrial Estate, Cilegon City, Banten, with a land area of 20,552 m². The workforce required for this plant is 150 people, with the business entity form of a Limited Liability Company (PT) led by a director under a line and staff organizational system. For the establishment and operation of the plant, an investment capital of IDR 732,788,073,442 and a production cost of IDR 650,348,812,816 are required. Based on the feasibility analysis, this plant has a BEP of 35,583%, an ROI of 21,138%, a POT of 4 years and 9 months, an RON of 35,230%, and an IRR of 21.512%. The results of the economic analysis conclude that the preliminary design for a hexamethylenediamine plant from adiponitrile and hydrogen using a Raney nickel catalyst is feasible to establish.
