Abstract
Kualitas gas merupakan parameter utama penentu nilai jual gas atau disebut sweet gas. Pemurnian perlu dilakukan untuk mengurangi gas impuritas terkandung. Proses pemurnian menggunakan absorber berbasis Amina. Gas impuritas hasil absorbsi diproses sehingga menghasilkan manfaat ekonomi dengan penjualan CO2. Pada penelitian ini menganalisis pengaruh tekanan, suhu, dan massflow absorber berupa monoethanolamine (MEA) terhadap kualitas dan penyerapan CO2. Selanjutnya dilakukan analisis tekno-ekonomi. Penelitian menggunakan software simulasi proses untuk pengambilan data simulasi berdasarkan data sheet perusahaan. Setelah dianalisa diketahui bahwa tekanan, suhu, dan massflow MEA berpengaruh terhadap kualitas gas dan jumlah CO2 terserap dengan hasil kualitas gas terbaik 98,46% dengan CO2 terserap sebanyak 53477,126 lb/h. Secara teori Semakin tinggi nilai parameter semakin baik hasil yang didapatkan namun pada kondisi tertentu terdapat kondisi khusus untuk mendapatkan nilai optimal. Parameter tekanan MEA optimal pada 1 bar menyesuaikan tekanan atmofer, sedangkan parameter suhu MEA optimal pada suhu 40oC, dan untuk massflow optimal pada 320.000 lb/h. Selanjutnya dilakukan optimisasi analisis tekno-ekonomi dengan menghitung PayBack Periode sehingga didapatkan PayBack Periode dalam 6 tahun 5 bulan, dengan IRR sebesar 14,56%.

Gas quality is the main parameter determining the selling value of gas or what is called sweet gas. Purification needs to be done to reduce gas impurities. The purification process uses an amine-based absorber. The impurity gas resulting from absorption is processed which can produce economic benefits by selling CO2. In this study, we analyzed the effect of pressure, temperature, and mass flow absorber in the form of amine on the quality and CO2 absorber. Next, a techno-economic analysis is carried out. The research uses process simulation software to collect simulation data based on company data sheets. After analysis, it was discovered that pressure, temperature and MEA mass flow had an effect on gas quality and the amount of CO2 absorbed with the best gas quality being 98.46% with CO2 absorbed of 53477.126 lb/h. In theory, the higher the parameter value, the better the results obtained, but under certain conditions there are special conditions to obtain optimal values. The optimal MEA pressure parameter at 1 bar adjusts the atmospheric pressure, while the optimal MEA temperature parameter is at 40oC, and for optimal mass flow at 320,000 lb/h. Next, optimization of the techno-economic analysis was carried out by calculating the PayBack Period so that the PayBack Period was obtained in 6 years and 5 months with IRR value in 14,56%.
