Operation of a MEG pilot regeneration system for organic acid and alkalinity removal during MDEA to FFCI switchover
Journal of Petroleum Science and Engineering, 2018Co-Authors: Adam Soames, Edith A. Odeigah, Ammar Al Helal, Sami Zaboon, Stefan Iglauer, Ahmed Barifcani, Rolf GubnerAbstract:Abstract The switch over from pH stabilisation using MDEA to film forming corrosion inhibitors (FFCI) may be beneficial following formation water breakthrough during hydrocarbon transportation and processing to prevent scaling at elevated pH and to extend the operational lifespan of a field. Where formation water is present, organic acids including acetic can be expected within MEG regeneration systems and can impose a corrosion risk together with carbon dioxide. A case study was performed to evaluate the potential of simultaneous removal of organic acids and MDEA/alkalinity during the switch over from pH stabilisation to film forming corrosion inhibitors (FFCI). Experimental testing was conducted using a MEG pilot regeneration plant operated by the Curtin Corrosion Engineering Industry Centre. Sufficient removal of organic acids was achieved to prevent accumulation within the MEG regeneration loop and subsequent corrosion issues through distillation by lowering the pH of the rich Glycol feed to six to promote removal of organic acids with the water distillate. Simultaneously, removal of MDEA and reduction of Lean Glycol alkalinity was achieved through the reclamation system to facilitate FFCI switchover more rapidly than a comparative industrial operational methodology.

simulasi pengaruh suhu Lean Glycol pada proses gas dehydration unit di industri gas alam
DISTILAT: JURNAL TEKNOLOGI SEPARASI, 2020Co-Authors: Mohammad Dwiky Darmawan, Ariani ArianiAbstract:Gas dehydration merupakan proses penyerapan uap air pada campuran gas dengan absorben tr i eth y lengl y col (TEG). Salah satu alat yang berperan penting di Gas Dehydration Unit adalah Contactor . Proses yang terjadi pada contactor ini adalah proses absorpsi, dimana gas alam mengalir dari bawah kolom melewati bubble cap tray , membentuk gelembung-gelembung kecil gas di fase cair. Absorben mengalir dengan arah yang berlawanan dengan campuran gas sehingga gas yang keluar contactor kandungan airnya berkurang. Di Industri sering terjadi masih tingginya kandungan air di fase gas yang keluar. Ini perlu diturunkan dengan melakukan uji coba menggunakan metode simulasi. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh suhu absorben TEG ( Lean Glycol ) terhadap kandungan air dan methane di fase gas keluar ( dry gas ). Metode yang digunakan adalah simulasi sensitivity study berbasis perangkat lunak. Data masukan didapat dari data harian gas flow computer (GFC) di Industri. Berdasarkan hasil simulasi kondisi terbaik didapatkan pada suhu 45℃ dengan kandungan air di dry gas sebesar 1,0328 kg/jam dan fraksi mol methane sebesar 0,8967.
