Piping

Development of novel epoxy closed-cell foam for personnel and corrosion protection—Part 1

Belzona Inc.: Oharriz, O.

Most industrial assets operating at elevated temperatures require thermal insulation for energy conservation, thermal protection or process stabilization.

A system approach to mitigating corrosion under insulation

Owens Corning: Cusick, A.

This article will consider how a system approach can help mitigate the risk of CUI and contribute to the performance and longevity of piping and equipment.

Shell to shut Gulf of Mexico crude pipes for two weeks in September

Shell said this week it plans to shut for two weeks in September a key crude oil pipeline in Gulf of Mexico that supplies oil to Louisiana refineries.

Creating opportunities for future fluid machinery experts

Reliability/Equipment Editor: Bloch, H. P.

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

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

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

ValveMan: Welsford, G.

Some of the highly corrosive fluids in the oil and gas industry contain the following compounds: carbon dioxide, hydrogen sulfide, chlorides and moisture.

Use a simple vapor equation for sizing two-phase pressure relief valves

Covestro: Kim, J. S.  |  Li, P.  |  Haines, R. J.
Bechtel: Lopez, J. P.

Pressure relief valves (PRVs) protect process equipment from the hazards of excessive over-pressure.

Reliability: When to consider liquid-ring compressors

Process Machinery Consulting: Bloch, H. P.

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.

Business Trends: Non-OEM parts—Buyer beware

Emerson: Boyle, B.

What is the harm in wearing a knock-off Rolex watch?

Investigations of high pressure drop observed in ASU columns

China National Air Separation Engineering Co.: Xu, F.-J.  |  Zhou, F.-H.  |  Cao, Z.-M.
Sulzer Chemtech: Zuber, L.
Sulzer Chemtech China: Dong, J.-J.

The measured pressure drop of columns in air separation units (ASUs) is often reported as being higher than the predicted pressure drop.
