Abstract
Hidrogen Sulfida (H2S) merupakan gas berbahaya yang dapat ditemukan pada limbah gas proses produksi dan eksplorasi minyak dan gas bumi. Metode yang dapat digunakan untuk menghilangkan kandungan H2S salah satunya metode pembakaran pada Thermal Oxidizer. Namun, pembakaran tidak selalu dapat menurunkan kandungan H2S dengan maksimal apabila proses pembakaran tidak terjadi dengan sempurna (bahan bakar tidak habis bereaksi dengan O2) atau suhu ideal pembakaran tidak tercapai (816OC). Oleh karena itu, pada tugas akhir ini diusulkan desain controller proses pembakaran H2S berbasis Air to Fuel Ratio Controller (AFRC) menggunakan Fuzzy PID Controller sebagai solusi agar pembakaran dapat berlangsung sempurna dan mencapai suhu ideal, sehingga kandungan H2S dapat diturunkan hingga ambang batas. Berdasarkan hasil simulasi didapatkan kandungan H2S sisa pada gas buang dapat dijaga pada nilai 0.12 - 0.097 ppm (<4ppm) dan kandungan O2 pada gas buang 1.5-2.02%, Sedangkan untuk respon Fuzyy PID Controller diperoleh nilai eror steady state 0.0416%, overshoot 0.029% serta settling time 21 detik.

Hydrogen Sulfide (H2S) is a dangerous gas that can be found in waste gas on production and exploration process of oil and gas. Because of that, we have to reduce the H2S contents from the waste gas until its safe threshold. One of the methods that can be used to reduce the H2S content is a combustion method that can occur in the Thermal Oxidizer. However, combustion may not always reduce H2S content efficiently if the combustion process does not occur perfectly (not all fuel and Acid gas react with O2) or Burning ideal temperature is not reached (816OC). Therefore, this Final Project proposed controller design H2S combustion process based Air to Fuel Ratio Control (AFRC) using Fuzzy PID Controller as a solution to make the combustion process occur perfectly and reach the ideal temperature, so that the H2S content can be lowered to the threshold. Based on the results of the process simulation, the remaining H2S content in the exhaust gas can be lowered into 0.12 - 0.097 ppm (threshold <4ppm) and the O2 content of the exhaust gas is on 1.5 - 2.02% range. For the caracteristic of the sistem respon, it has steady state error 0.0416%, overshoot 0.029 and the settling time on 21 seconds.
