Enhancement of carbon dioxcide (CO2) removal process in liquefied natural gas (LNG) production system

Removal of CO2 from natural gas is currently a global issue, apart from meeting the customer's contract specifications and for successful liquefaction process in any LNG project, it is also a measure for reducing the global CO 2 emission. The aims of this research are to present a comprehensive...
