Abstract

Kolom C3/C4 Splitter (19-C-101) pada Propylene Recovery Unit (PRU) PT Kilang Pertamina Internasional RU VI Balongan berperan penting dalam memisahkan fraksi C3 (propana-propilena) dan C4 (butana-butilena). Permasalahan yang ditemukan pada kondisi operasi aktual adalah masih terbawanya fraksi C4, khususnya iso-butana, ke produk atas sehingga menurunkan kemurnian fraksi C3 dan meningkatkan beban proses pemurnian lanjutan. Penelitian ini bertujuan mengevaluasi dan mengoptimalkan kinerja kolom menggunakan Aspen HYSYS V.15 berdasarkan data operasi periode September 2025. Variabel operasi yang dioptimasi meliputi reflux rate dan temperatur bottom column. Hasil evaluasi menunjukkan recovery propana dan propilena mencapai 99,99%, namun produk atas masih mengandung iso-butana sebesar 42,214%. Kondisi operasi optimum diperoleh pada reflux rate 89,50 ton/jam dan temperatur bottom column 104,5°C, yang mampu menurunkan kandungan iso-butana pada produk atas menjadi 26,47% tanpa meningkatkan kehilangan propilena secara signifikan. Optimasi ini menghasilkan peningkatan kualitas pemisahan serta memberikan keuntungan ekonomi sekitar Rp6,01 miliar per tahun dibandingkan kondisi operasi aktual. Hasil penelitian menunjukkan bahwa pengaturan reflux rate dan temperatur bottom column merupakan parameter penting untuk meningkatkan efisiensi pemisahan dan profitabilitas operasi kolom C3/C4 Splitter.
=================================================================================================================================
The C3/C4 Splitter Column (19-C-101) in the Propylene Recovery Unit (PRU) of PT Kilang Pertamina Internasional RU VI Balongan plays a crucial role in separating C3 hydrocarbons (propane and propylene) from C4 hydrocarbons (butane and butylene). An operational issue identified during plant operation was the carryover of C4 components, particularly iso-butane, into the overhead product, resulting in reduced C3 product purity and increased downstream processing load. This study aimed to evaluate and optimize the column performance using Aspen HYSYS V.15 based on operating data collected in September 2025. The optimization focused on two key operating parameters: reflux rate and bottom column temperature. Simulation results showed that propane and propylene recoveries reached 99.99%; however, the overhead product still contained 42.214% iso-butane under actual operating conditions. The optimum operating condition was achieved at a reflux rate of 89.50 ton/h and a bottom column temperature of 104.5°C, reducing the iso-butane content in the overhead product to 26.47% without significantly increasing propylene losses. The optimization improved separation performance and generated an estimated economic benefit of approximately IDR 6.01 billion per year. These results demonstrate that reflux rate and bottom column temperature are critical parameters for enhancing the efficiency and profitability of C3/C4 Splitter column operations.
