Solvent Deasphalting: Why is there so much buzz?

Hemendra Khakhar Facilitator: Hemendra Khakhar – Technology Licensing Director, Wood PLC, Houston


Many refiners are struggling to meet new product specifications and improve refinery margins simultaneously while dealing with large resid pool. The choice for resid upgrading technology and flow scheme is of paramount importance especially in the face of the IMO 2020 regulations. The ability to reliably minimize fuel oil production, maximize high quality distillate yields, and achieve high conversion is essential for sustaining the value of installed assets in the years to come. Solvent Deasphalting (SDA) is a mature technology which is enjoying a renaissance today. Traditionally used for lubes and asphalt production, today it is being increasing incorporated into residue processing schemes to increase yields and optimize the refinery configuration. 

This presentation will look at how refiners are integrating SDA into their refineries to debottleneck existing residue conversion units as well applications in grass roots facilities. It will focus on innovative resid processing flow schemes to improve refining margins, improving liquid yields and how to leverage existing assets to reduce fuel oil exposure. With the oil market fluctuations destined to arise in the coming years, refiners should look at ensuring they have feed flexibility and conversion options in their bottoms processing to maximize profits.
