Abstract
Methods and systems for separating hydrocarbons using one or more dividing wall columns are provided. The method can include introducing a hydrocarbon fluid to a first dividing wall column. A first overhead comprising methane, ethane, or a combination thereof, a first intermediate comprising ethane, a second intermediate comprising ethane, and a first bottoms comprising one or more hydrocarbons having three or more carbon atoms per molecule can be recovered from the first dividing wall column. The first overhead can be introduced to a process for producing a liquefied natural gas. The first bottoms can be introduced to a second dividing wall column. A second overhead comprising propane, a third intermediate comprising butane, and a second bottoms comprising one or more hydrocarbons having five or more carbon atoms per molecule can be recovered from the second dividing wall column. The second overhead can be introduced to the process for producing a liquefied natural gas.
