Turboexpander reliability has increased steadily over time

Expander-compressor units provide refrigeration for extracting heavier hydrocarbon components while having low energy costs.

Turbomachinery components & auxiliary systems loom large

For many component and auxiliary system vendors, 2020 was a rough year. Operators deferred maintenance and upgrades. 2021 has a rosier outlook.

Myth: Additive Manufacturing is the Answer for Everything

AM is the best thing since sliced bread, they said. But has the potential of AM for compressor manufacturing been more promise than reality?

Fog system upgrades

Reducing maintenance costs by upgrading aging inlet air-cooling systems.

Vendor spotlight: Elliott Group

Elliott Group manufactures centrifugal and axial compressors, steam turbines, power recovery expanders, cryogenic pumps, and cryogenic expanders.

The effect of eddy grooves on tilting pad journal bearings

Tilting pad journal bearings are used in turbocompressors, turbo gears, gas turbines, and steam turbines.

Piping and Nozzle Loads

Many factors once considered negligible in ordinary piping may become significant for piping connected to turbomachinery.

Winterizing turbomachinery and protecting equipment from extreme weather

Winterizing and protecting turbomachinery can mitigate the impact of extreme weather events on the industry’s ability to meet power demands.

Blue Hydrogen Hub for North Dakota

Bakken Energy and Mitsubishi Power have signed an agreement to create a hydrogen hub in North Dakota.

Who is to blame for the Texas grid outages?

The ERCOT grid in Texas works well with renewable energy. But increasing the volume of renewables further may not be practical. More generation of all types and greater attention to winter readiness is needed.

Solving U.S. Transmission

A stable renewable-rich grid needs transmission build-out, and incentivized ancillary services.

My test is accurate

Many of us have to verify compressor and driver performance in the field. We do a test, read the data, and convert it to flow, head, and some other parameters. Voila, we have done a valid test and we believe our data. Not so fast!

Tip: Don't overlook resonance in turbomachinery failures

There are many reasons for turbomachinery problems and failures. Resonance, for example, is often overlooked.

Drones, Scarcity, Efficiency: Repair & Maintenance in 2021

Technologies are emerging to perform maintenance, repairs, retrofits, and overhauls while gauging asset health remotely. Drones are being deployed for inspections. Some parts can be scarce, so plant operators are increasingly seeking alternatives.

Energy transition to green uncertainty

Many attendees and speakers at the 39th Annual CERAweek wanted to know about the contemplated transition from fossil fuels to green energy. How fast will it happen? What has gone right so far? What could go wrong? Ask three energy experts, get three different answers. Ask three politicians, get nine different answers.

‘Crystal critter’ research has implications for anti-fouling technology

New research shows new ways for engineers to prevent the build up of minerals in power plants and possibly use salt water instead of fresh water for cooling.
