Methyldiethanolamine (MDEA) atau yang sering disebut amine memiliki rumus CH3N(C2H4OH)2 adalah suatu cairan kimia ketika dicampurkan dengan 50 % air mempunyai kemampuan untuk menyerap CO2 dari stream gas dan dapat dilepas kembali memanaskan sampai di atas suhu penguapan air. Amine banyak mengandung rich amine. Richamine dipanaskan tujuan menghilangkan kemudian lean Pengujian pada content ini ya...

Pyrolysis of waste tyres produces harmful hydrogen sulfide and other mercaptan compounds as by-products. The current study is concerned with the purification hydrogen-rich pyrolysis gas from that present in a great amount (up to 5.1% mol at 420 °C), mercaptans are also problematic impurities. method proposed absorption by alkanolamines which one most economical methods applied natural sweetenin...

Carbon dioxide emissions are the largest greenhouse gases contributor, which is attributed to global warming. Therefore, capture of CO2 necessary, especially from large point sources. Post-combustion using chemical solvents most matured technology. In this paper, mixed methyldiethanolamine (MDEA) and piperazine (PZ) were studied potentially address some issues related use conventional monoethan...

Hydrogen sulfide is essentially removed from the raw natural gas to meet process, health, safety and environmental standards. Alkanolamine based absorption process remains prevalent technique for hydrogen removal due ease of operation economic considerations. The design such separation systems a critical factor in meeting stringent requirements optimizing operations. To achieve precise design, ...

The present study evaluated the environmental impacts of post-combustion CO2 capture and recovery via membrane–gas absorption processes. We have used SimaPro v.9 packages with Ecoinvent v3.5 database employing two different methods, ReCiPe 2016 Endpoint (H) Midpoint (H), considering a fundamental methodological framework to determine most environmentally friendly experimental condition. Life cy...

In this work, carbon dioxide (CO2) loading capacity of methyldiethanolamine (MDEA) solution promoted by potassium lysinate (KLys) was experimentally measured using a gas absorption setup at different concentrations and temperatures. The CO2 removal efficiency the MDEA + KLys investigated for CO2/N2 mixture computational fluid dynamic (CFD) simulations in hollow fiber membrane contactor (HFMC). ...
