Abstract

Dimethyl Carbonate (DMC) adalah senyawa oksigenat yang memiliki potensi sebagai aditif bahan bakar dengan kandungan oksigen tinggi dan mampu meningkatkan efisiensi pembakaran serta mengurangi emisi gas buang. Selain itu, DMC memiliki berbagai aplikasi dalam industri farmasi, pelapis, sintesis kimia organik, serta sebagai elektrolit baterai ion litium. Pada pra-desain ini, dirancang pabrik DMC menggunakan bahan baku CO2, metanol, CeO2, dan 2-cyanopyridine, dengan memanfaatkan emisi gas CO2 dari ExxonMobil Cepu Ltd. di Kabupaten Bojonegoro, Jawa Timur. Proses produksi menggunakan metode sintesis langsung pada suhu 120°C dan tekanan 0,101 MPa (1,01 bar) dengan kapasitas produksi 110.000 ton/tahun serta target konversi >99,5%. Pemilihan lokasi pabrik mempertimbangkan kedekatan dengan sumber bahan baku CO2, pasar potensial seperti PT Pertamina RU IV Cilacap dan RU VI Balongan, serta aspek utilitas, aksesibilitas, sumber daya manusia, dan regulasi. Dengan kebutuhan bahan baku CO2 sebesar 7.848,836 kg/jam, metanol 11.047,197 kg/jam, dan 2-cyanopyridine 30.498,927 kg/jam, pabrik ini diharapkan mampu mendukung pengurangan emisi gas rumah kaca sekaligus menghasilkan produk bernilai ekonomi tinggi.

Dimethyl Carbonate (DMC) is an oxygenate compound with potential as a fuel additive due to its high oxygen content, which enhances combustion efficiency and reduces exhaust emissions. Additionally, DMC has diverse applications in the pharmaceutical industry, coatings, organic chemical synthesis, and as an electrolyte in lithium-ion batteries. This preliminary plant design proposes the production of DMC using CO2, methanol, CeO2, and 2-cyanopyridine as raw materials, utilizing CO2 emissions from ExxonMobil Cepu Ltd. in Bojonegoro Regency, East Java. The production process employs direct synthesis at a temperature of 120°C and a pressure of 0.101 MPa (1.01 bar), with a production capacity of 110,000 tons/year and a target conversion rate of >99.5%. The plant location was selected based on its proximity to CO2 sources, potential markets such as PT Pertamina RU IV Cilacap and RU VI Balongan, and considerations including utilities, accessibility, human resources, and regulatory aspects. With raw material requirements of 7,848.836 kg/h for CO2, 11,047.197 kg/h for methanol, and 30,498.927 kg/h for 2-cyanopyridine, this plant is expected to contribute to reducing greenhouse gas emissions while producing a high-value economic product.
