Sofronas, A., Consulting Engineer

With the help of an excellent mentor, I became adept at analyzing equipment and structures at the start of my career, using analytical techniques.

Reliability: Dry gas sealing technology replaces segmented carbon rings in small steam turbines

Bloch, Heinz P., Hydrocarbon Processing Staff

Since the late 1800s, small steam turbines have incorporated bushing-type, single-piece and/or segmented carbon gland components to reduce and prevent steam leakage along the shaft.

Editorial Comment: Biofuels—A viable fuel source for the future?

Nichols, Lee, Hydrocarbon Processing Staff

This issue of Hydrocarbon Processing focuses on the use of alternative feedstocks and biofuels. The goal of utilizing these technologies is to produce fuels and products that lower total carbon output/emissions, which is a major focus in decarbonizing economies around the world.

Incorporate assurance into an operational readiness program—Part 2

Picheo, G., Reed, W., Jacobs Consultancy

Investors have a critical need for assurance that the asset they are invested in will achieve continuous operation at the designed rates, as well as meet—and hopefully surpass—reliability, availability and maintenance targets safely.

Migrating from Fortran to ISA S-88

Ford, J., Kolluri, T., Bozeman, J., MAVERICK Technologies

A major refiner operates two catalytic reforming units for gasoline octane improvement and aromatics production in Texas. In each of these units, five reactors filled with catalyst are operated continuously in series to reform paraffinic hydrocarbons in the presence of hydrogen (H2). During this process, some byproduct coke is unavoidably produced and deposits on the catalyst, which leads to gradual catalyst deactivation.
