AM-96-69 A COST EFFECTVE WAY TO DEAL WITH SEVERAL PARAMETERS OF REFORMULATED FUELS: Light Cracked Naphtha Deep Etherification

Description:

The Clean Air Act Amendment (CA4A) of 1990 set in motion changes in the Refining Industry, specifically the Complex Model which comes into force after 1998 as well as possible changes beyond that which will affect the Refiner. These requirements result in drastic changes in refinery operations and economics: 1. Reduced Reformer severity to limit Aromatics production. This results in reduced production and possible shortage of hydrogen and octane. 2. Reduction in gasoline pool RVP and the need to reduce the light olefins content. 3. The need for Oxygenates in the gasoline pool. This paper discusses an effective method of dealing with all these changes by Deep Etherification of the entire Light Cracked Naphtha (LCN) stream from the Refinery’s Fluid Catalytic Cracker.
