Abstract
Hydrocarbon processing apparatuses and methods of refining hydrocarbons are provided herein. In an embodiment, a method of refining hydrocarbons includes providing a cracked stream that includes a sulfur-containing component and cracked hydrocarbons. The cracked stream is compressed to produce a pressurized cracked stream. The pressurized cracked stream is separated to produce a pressurized vapor stream and a liquid hydrocarbon stream. The pressurized vapor stream includes C4− hydrocarbons and the liquid hydrocarbon stream includes C3+ hydrocarbons. The liquid hydrocarbon stream is separated to produce a first liquid absorption stream that includes C5+ hydrocarbons and a C4− hydrocarbon stream. C3+ hydrocarbons are absorbed from the pressurized vapor stream through liquid-vapor phase absorption using the first liquid absorption stream. The sulfur-containing component is removed prior to absorbing C3+ hydrocarbons from the pressurized vapor stream.
