Abstract

In the oil and gas production process, apart from hydrocarbons, a number of impurities are produced, including CO2 and sulfur in various concentrations, depending on the conditions and characteristics of the reservoir and the location where the oil and gas is located. To process sulfur removal from condensate, the common technology is HDS (Hydrodesulfurization). However, with process requirements such as high temperature, pressure, and intensive hydrogen consumption, an alternative technology is needed for this desulfurization. One of them is oxidative-extractive desulfurization. Technical and economic evaluations to determine the feasibility of applying on an industrial scale need to be studied further. The study of oxidative-extractive desulfurization process of sulfur compounds (represented as dibenzothiophene, DBT) was carried out using H2O2/formic acid as oxidizing agent and catalyst, as well as extraction with DMF. For a capacity of 1000 bpd of condensate with 1%-wt sulfur, desulfurization was successfully carried out with sulfur removal of 96.55% and condensate recovery of 99.41%. A processing fee of 9.14 USD/barrel is required, of which 84% is required for chemicals. The alternative process configuration for DMF recovery succeeded in reducing chemical costs by 35.5% and reducing total processing costs by 27.0% to 6.67 USD/barrel. In this alternative process configuration, 95.80% sulfur removal was achieved with condensate recovery of 99.21%.

Abstract

Dalam proses produksi minyak dan gas, selain hidrokarbon, dihasilkan pula sejumlah pengotor antara lain CO2 dan sulfur dengan konsentrasi yang bervariasi, tergantung pada kondisi dan karakteristik reservoir serta lokasi dimana minyak dan gas tersebut berada. Untuk proses penghilangan sulfur dari kondensat, teknologi yang umum digunakan adalah HDS (Hydrodesulfurization). Namun dengan kebutuhan proses seperti suhu tinggi, tekanan, dan konsumsi hidrogen yang intensif, diperlukan teknologi alternatif untuk desulfurisasi ini. Salah satunya adalah desulfurisasi oksidatif-ekstraktif. Evaluasi teknis dan ekonomi untuk mengetahui kelayakan penerapan pada skala industri perlu dikaji lebih lanjut. Kajian proses desulfurisasi oksidatif-ekstraktif senyawa sulfur (direpresentasikan sebagai dibenzothiophene, DBT) dilakukan dengan menggunakan H2O2/asam format sebagai oksidator dan katalis, serta ekstraksi dengan DMF. Untuk kapasitas 1000 bpd kondensat dengan sulfur 1%-wt, desulfurisasi berhasil dilakukan dengan removal sulfur sebesar 96,55% dan recovery kondensat sebesar 99,41%. Diperlukan biaya pemrosesan sebesar 9,14 USD/barel, dan 84% di antaranya diperlukan untuk bahan kimia. Konfigurasi proses alternatif untuk pemulihan DMF berhasil menurunkan biaya bahan kimia sebesar 35,5% dan menurunkan total biaya pemrosesan sebesar 27,0% menjadi 6,67 USD/barel. Pada konfigurasi proses alternatif ini, penghilangan sulfur mencapai 95,80% dengan perolehan kondensat sebesar 99,21%.
