Lieberman, N.

Process Improvement Engineering, Metairie, Louisiana

Norm Lieberman graduated with a degree in chemical engineering from The Cooper Union in New York in 1964. In 1965, while working for Amoco Oil, he designed the first complex fractionator using a computer simulation (i.e., with side draws, side strippers and pumparounds). Over 18,000 engineers and technicians have attended Mr. Lieberman’s refinery troubleshooting seminars since 1983. Based in New Orleans, Mr. Lieberman specializes in the retrofit design of crude units, FCU fractionators, delayed cokers, sulfuric acid alkylation plants and sulfur recovery units.

Set refinery profitability goals

Johnson, A., Johnson, E., Graham Corp.; Lieberman, N., Process Improvement Engineering

While the ultimate purpose of operating a refinery is to produce gasoline, diesel or asphalt, key objectives include improving return on investment (ROI), net profitability and cash flow.

Wieslaw, T., Nichols, J., Sasol; Lieberman, N., Process Improvement Engineering; Johnson, E., Graham Corp.

A system of compressors powered by surface condensing steam turbines is inherent in the operation of a typical ethane cracker unit.

Performance testing: The key to successful revamps

Lieberman, N., Process Improvement Engineering

Process unit revamps often do not result in a refiner achieving its desired objectives. This is typically not the result of mechanical defects with process equipment.
