Abstract
Etilen glikol (monoetilen glikol/MEG) merupakan salah satu bahan kimia antara yang memiliki peran strategis dalam industri petrokimia, khusunya sebagai bahan baku utama produksi polyethylene terepthalate (PET) dan serat poliester. Kebutuhan MEG di Indonesia terus meningkat seiring dengan pertumbuhan industri tekstil dan kemasan, namun kapasitas produksi domestik masih terbatas yang hanya dipasok oleh satu industri yaitu PT Polychem Indonesia Tbk sehingga ketergantungna terhadap impor tetap tinggi. Berdasarkan hal tersebut, perancangan pabrik etilen glikol di dalam negeri menjadi langkah strategis untuk mendukung kemandirian industri nasional dan memperkuat rantai pasok petrokimia. Pabrik etilen glikol berbahan baku etilen oksida dan air ini dirancang dengan dua tahapan proses utama, yaitu pembentukan etilen oksida dengan proses oksidasi langsung berbasis udara menggunakan katalis perak, serta proses hidrasi katalitik etilen oksida menjadi etilen glikol menggunakan katalis Amberjet 4200/HCO3-. Produk utama yang dihasilkan adalah monoetilen glikol (MEG) dengan kemurnian >99%. Selain itu, terdapat produk samping berupa dietilen glikol (DEG) dan trietilen glikol (TEG) yang masih memliki nilai ekonomi. Ketersediaan bahan baku untuk pabrik etilen glikol ini didukung oleh keberadaan PT Chandra Asri Tbk yang memproduksi etilen dan juga dengan dimulainya operasi produksi etilen PT LOTTE Chemical Indonesia di Cilegon. Secara keseluruhan, Perancangan pabrik ini diharapkan mampu menjadi solusi dalam mengurangi ketergantungan impor terhadap MEG dan mendukung industri hilir di Indonesia.

Ethylene glycol (monoethylene glycol/MEG) is one of the intermediate chemicals that has a strategic role in the petrochemical industry, especially as the main raw material for the production of polyethylene terephthalate (PET) and polyester fiber. The need for MEG in Indonesia continues to increase along with the growth of the textile and packaging industry, but domestic production capacity is still limited, supplied only by one industry, namely PT Polychem Indonesia Tbk, so that dependence on imports remains high. Based on this, the design of a domestic ethylene glycol plant is a strategic step to support the independence of the national industry and strengthen the petrochemical supply chain. This ethylene glycol plant, which uses ethylene oxide and water as raw materials, is designed with two main process stages: the formation of ethylene oxide by an air-based direct oxidation process using a silver catalyst, and the catalytic hydration process of ethylene oxide to ethylene glycol using an Amberjet 4200/HCO3- catalyst. The main product produced is monoethylene glycol (MEG) with a purity of >99%. Additionally, diethylene glycol (DEG) and triethylene glycol (TEG) are byproducts that still have economic value. The availability of raw materials for this ethylene glycol plant is supported by the presence of PT Chandra Asri Tbk, which produces ethylene, and by the commencement of ethylene production operations by PT LOTTE Chemical Indonesia in Cilegon. Overall, this plant design is expected to be a solution to reduce dependence on MEG imports and support downstream industries in Indonesia.
