Abstract

Sistem pembuangan dan pembakaran (flaring system) merupakan komponen kritikal dalam menjaga keselamatan operasi pada kilang minyak dan gas bumi. Penelitian ini bertujuan untuk menganalisis ketahanan suhu tinggi dari tiga variasi material yang potensial digunakan dalam fabrikasi ujung suar (flare tip), yaitu baja tahan karat (SS) 310, SS 304, dan SS 304 yang dilapisi Thermal Barrier Coating (TBC) berbasis Yttria-Stabilized Zirconia (YSZ). Metode pengujian dilakukan melalui siklus termal di dalam tungku suhu tinggi pada temperatur 500^∘ "C" dan 1000^∘ "C" selama 8 jam per siklus, dengan total durasi akumulatif 24 jam (3 siklus). Karakterisasi material sebelum dan sesudah pengujian dilakukan menggunakan X-ray Diffraction (XRD), X-ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), pengamatan metalografi, serta uji kekerasan. Selain karakteristik mekanis dan struktural, aspek keekonomian fabrikasi juga turut dipertimbangkan. Hasil penelitian menunjukkan bahwa baja tahan karat 304 dengan lapisan TBC-YSZ memiliki ketahanan suhu tinggi yang unggul. Material ini tidak mengalami penurunan nilai kekerasan yang signifikan maupun perubahan mikrosturktur yang merugikan setelah pemanasan. Oleh karena itu, baja tahan karat 304 berlapis TBC layak direkomendasikan sebagai material alternatif yang efektif dan ekonomis untuk fabrikasi komponen flare tip pada industri migas.

The flaring system is a critical component ensuring operational safety in oil and gas refineries. This study aims to evaluate the high-temperature resistance of three candidate materials for flare tip fabrication: stainless steel (SS) 310, SS 304, and SS 304 coated with an Yttria-Stabilized Zirconia (YSZ) Thermal Barrier Coating (TBC). Thermal cyclic testing was conducted in a high-temperature furnace at 500^∘ "C" and 1000^∘ "C" for 8 hours per cycle, totaling an accumulative exposure of 24 hours over 3 cycles. Material characterization prior to and following the thermal exposure was performed using X-ray Diffraction (XRD), X-ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), metallographic analysis, and hardness testing. Economic aspects of fabrication were also considered alongside technical performance. The results demonstrated that the TBC-YSZ coated SS 304 exhibited superior high-temperature resistance. The material maintained its hardness and showed no detrimental microstructural degradation after thermal cycling. Consequently, TBC-coated SS 304 offers a viable, cost-effective alternative material for flare tip fabrication in the oil and gas industry.
