Creating opportunities for future fluid machinery experts

Bloch, H. P., Reliability/Equipment Editor

The state of understanding science and facts on one side and distinguishing these from anecdotes and often far-fetched opinions on the other side should be concerning to us. Institutions of higher learning can be disinclined to teach needed, applicable or actionable knowledge.

HRSG water/steam sampling: Do it right or face potential consequences

Buecker, B., ChemTreat, Inc.; Powalisz, J., Sentry Equipment Corp.

Many large industrial facilities—including refineries, and chemical and petrochemical plants—are increasingly turning to co-generation for process steam and power production.

The effects of highly corrosive fluids on valves and disasters that can be avoided

Reliability: When to consider liquid-ring compressors

Bloch, H. P., Process Machinery Consulting

Liquid-ring compressors (FIG. 1) use the centrifugal whirling of a sealing liquid to create a series of piston-like water columns to trap gas or vapor between the impeller cells of a rotor installed eccentric to its casing.
