gas pushes energy industries to explore the reservoirs contain
high CO2 concentration
and impurities including heavy hydrocarbons. High efficiency of
using membrane technology in CO2-natural gas separation
has extended its potential application to offshore environment.
Due to the limited studies related with the separation of CO2 under
offshore conditions, the present work has investigated the separation
performance of a commercial membrane in removing bulk CO2 from
methane at elevated pressure condition. A wide range of offshore
operating conditions including, pressure from 10 to 50 bar, CO2 concentration
from 25 to 70% and temperature of 30oC, 40oC
and 50oC were studied. High relative CO2 permeance and relative CO2/CH4 selectivity
were observed when the pressure and the CO2 concentration
increased. This work, therefore substantial is to bridge the gap
and facilitates the application of membrane technology for offshore
operating conditions. Keywords: Bulk CO2;
membrane process; natural gas separation ABSTRAK Peningkatan permintaan terhadap
gas asli telah
mendorong industri tenaga untuk meneroka
takungan yang mengandungi
kepekatan CO2 dan bendasing yang tinggi termasuk hidrokarbon berat. Kecekapan tinggi dalam penggunaan
teknologi membran
dalam pemisahan CO2-gas
asli telah
meningkatkan potensi aplikasi kepada persekitaran luar pesisir. Disebabkan kajian yang berkaitan
dengan pemisahan
CO2 di
luar pesisir
yang terhad, kajian terkini telah mengkaji
prestasi pemisahan
membran komersial dalam mengeluarkan CO2 pukal daripada metana pada keadaan
tekanan yang tinggi.
Pelbagai keadaan
operasi luar pesisir
termasuk tekanan
dari 10 kepada 50 bar, kepekatan CO2 dari 25% ke 70% dan suhu 30°C, 40°C dan 50°C telah dikaji. Ketelapan relatif CO2 dan kepemilihan CO2/CH4 relatif yang tinggi telah diperhatikan apabila tekanan dan kepekatan CO2 meningkat. Oleh itu, penyelidikan
ini penting
untuk merapatkan jurang dan memudahkan
penggunaan teknologi
membran bagi keadaan
operasi luar
