How to predict fluid coker performance

New model helps estimate yields for 'bottom-of-the-barrel' residuals

Brown, W., ETX Systems Inc.

When evaluating technologies to treat the "bottom-of-the-barrel" residue, it is necessary to estimate the expected yields and qualities from the product liquids.  Fluid coking is a technology that currently upgrades a significant number of heavy barrels from Canada's oil sands.  Despite all data in the public domain, only rudimentary methods are available to estimate fluid coker performance. The presented new evaluation method can generate a feed specific characterization to estimate fluid-coker performance and can be used to estimate heavy-end product slate. A trial-and-error solution is applied, which is easily solved using standard spreadsheets. CALCULATION BASIS The model
