Description:

Reduced demand for residual fuels and potential economic benefits to be. gained by upgrading these materials to higher value products are incentives to consider refinery residual fuel upgrading schemes. As long as these two incentives exist, capital cost remains the major burden that must be overcome for an upgrading project to be viable. This paper presents the results of a study undertaken to evaluate the improved economic incentives for integrating the residual oil conversion processes of solvent deasphalting (SDA) and coking. Incentives for considering integration of the Residuum Oil Supercritical Extraction (ROSEm) SDA process licensed by M.W. Kellogg Technology Company and the FLUID COKING process licensed by Exxon Research and Engineering Company were investigated. Conditions that favor the FLUID,COKING process over conventional Delayed Coking were also noted. Six refinery configurations were evaluated using an LP model to define refinery balances, unit capacities and operating margins. Investment performance for these scenarios was then calculated based on estimated capital costs and the results from the LP models. Contained within this paper are the study bases, discussion of the resid processing options considered and conclusions. The results indicate that a combination of deep extraction ROSE unit processing atmospheric bottoms and Fluid Coker provides the most attractive economics when fuel. oil production is to be minimized. This result is due to the unique capability of the Fluid Coker to handle very heavy feeds efficiently and the ability of the ROSE process to upgrade residual fuels economically. When fuel oil can be marketed at an attractive price, ROSE offers the best return on capital and there is no justification for adding either a Delayed Coker or Fluid Coker. For many refiners, marketing of large quantities of fuel oil is not a viable option. These refiners might consider the upgrade alternatives such as those discussed here.
