Title:
油を脱瀝するためのシステムおよびプロセス
Document Type and Number:
Japanese Patent JP6980787
Kind Code:
B2
Abstract:
Processes for producing deasphalted oil are provided which involve combining a supercritical water stream with a pressurized, heated, hydrocarbon-based composition to create a combined feed stream, introducing the combined feed stream to a supercritical reactor to produce and upgraded product, and depressurizing the upgraded product. The depressurized upgraded product is separated into a light and a heavy fraction, where the heavy fraction has a greater concentration of asphaltene than the light fraction. The light fraction is passed to a separator to separate into a gas fraction, a paraffinic fraction, and a water fraction and the heavy fraction and the paraffinic fraction are combined to remove the asphaltene and produce deasphalted oil. In some embodiments, the paraffinic fraction is dewatered before combining with the heavy fraction.
