AFPM Recognizes Facilities with Outstanding Safety Practices

The American Fuel & Petrochemical Manufacturers (AFPM) has announced the winners of the 2021 Annual Safety Awards, part of the refining and petrochemical industries’ ongoing mission to enhance and recognize outstanding workplace safety. The awards, considered the industries’ premier awards, are part of a comprehensive program developed by the AFPM Safety and Health Committee to promote safe operations in the refining and petrochemical industries. They also recognize facilities that have outstanding occupational and process safety performance.

Question 50: What is the proper firefighting media to use when putting out a fire when both spent sulfuric acid and heavy hydrocarbon are present (e.g., in a spent acid tank or a diked area that has a layer of hydrocarbon floating on the spent acid)?

The water and acid will interact, which makes water a poor choice. Most of the foams of which we are aware are mostly water. A dry chemical will also react to the acid. So, as always, when you get into a fire situation, there’s some initial assessment that’s required of the fire.

Question 22: With the introduction of modern riser termination devices (RTDs) and the advent of severe FCC feed hydrotreating, what is your experience (typical values) with the ash content of the main fractionator bottoms (MFB) product? Please describe the testing methodology utilized and the recommended testing frequency for this stream. What process, practices, and/or equipment changes can be employed to reduce the ash content of the MFB product?

Sunoco’s FCCs operate primarily in resid cracking mode; either atmospheric or vacuum resid, typically without the benefit of upstream feed hydrotreating. We have FCCs with coupled two-stage riser termination devices, riser cyclones uncoupled to the secondaries, and simple RTDs followed by either single- or two-stage cyclones.
