Lieberman, N.
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. He can be contacted via email at norm@lieberman-eng.com.

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.
Troubleshooting vacuum operation of an inter-after condenser unit in an ethylene plant
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
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.
