Abstract

Emisi karbon adalah jumlah karbon atau emisi gas yang dihasilkan dari berbagai kegiatan manusia pada kurun waktu tertentu seperti karbondioksida (CO2) yang memberikan dampak radiasi matahari terperangkap di atmosfer bumi. Teknologi Carbon Capture, Utilization and Storage (CCUS) adalah proses di mana karbon dioksida dipisahkan dan diubah menjadi zat lain melalui reaksi kimia dengan hidrogen. CCUS juga dapat menghasilkan manfaat ekonomi dengan memanfaatkan kembali karbon dioksida. Pada penelitian ini penulis akan menganalisa pengaruh pressure, temperature dan laju aliran massa MEA pada penerapan CO2 absorption berbasis amina pada unit utilitas pengolahan gas plant dan akan didapatkan total biaya optimal pada CO2 absorber. Akan digunakan variabel bebas berupa pressure, temperature dan laju aliran massa MEA dan variabel kontrol berupa tekanan feed gas, temperature feed gas, dan laju alir feed gas. Penelitian ini akan menggunakan software simulasi proses untuk simulasinya dan akan didapatkan data penelitian berupa CO2 terserap. Setelah dianalisa diketahui bahwa pressure MEA tidak berpengaruh secara langsung terhadap CO2 terserap, sedangkan temperature dan mass flow MEA berbanding lurus dengan CO2 terserap. Selain itu didapatkan pula biaya total CO2 absorber yang harus dikeluarkan sebesar 3,231,986 USD per tahun dengan CO2 terserap sebesar 4,031.24 ton CO2 per tahun.

Carbon emissions refer to the amount of carbon or gas emissions generated from various human activities over a specific period, such as carbon dioxide (CO2), which contributes to the trapping of solar radiation in the Earth's atmosphere. Carbon Capture, Utilization and Storage (CCUS) technology is a process in which carbon dioxide is separated and transformed into other substances through chemical reactions with hydrogen. CCUS can also generate economic benefits by reusing carbon dioxide. In this study, the authors analyze the effect of pressure, temperature, and mass flow rate of MEA on the application of amine-based CO2 absorption in gas processing utility units, and obtain the total optimal cost of the CO2 absorber. The independent variables used are pressure, temperature, and mass flow rate of MEA, while the control variables are feed gas pressure, feed gas temperature, and feed gas flow rate. The study uses process software for simulation and obtains research data in the form of absorbed CO2. After analysis, it is found that MEA pressure does not directly affect absorbed CO2, while temperature and mass flow rate of MEA are directly proportional to absorbed CO2. In addition, the total cost of the CO2 absorber is found to be 3,231,986 USD per year with absorbed CO2 of 4,031.24 tons per year.
