Hubs connect one piece of machinery to another, usually with some flexible coupling between them. Installers have only limited time to work with the hot hub. When incorrectly positioned, it may have to be removed, which has the potential of damaging the shaft end.
Using smaller turbines (50 kW to 300 kW) can aid system efficiency and help conserve energy. We investigate examples in which the application of smaller steam turbines provided return on investment within two years.
Especially when handling hydrogen, reciprocating compressors must provide ruggedness, operating flexibility and energy efficiency at pressures up to 3,000 psi (200 bar).
Since organic fouling cannot be completely eliminated, ethylene producers must use operational, chemical and mechanical methods to minimize heat transfer losses and equipment downtime.

Engineers and designers are highly skilled individuals. Forcing them to enter design changes using tables, forms and spreadsheets is unproductive and uneconomical, and it increases the likelihood of human error—this is the way that most instrumentation software systems currently work. For too long, software vendors have denied engineers and designers the simple practicality of a graphical visual engineering interface with “drag and drop” capability and inbuilt intelligence, ensuring changes are automatically replicated into all the associated data and databases.

As low oil prices make naphtha cracking margins in Europe and Asia more competitive, are investments in new, ethane-based petrochemicals capacity in the US and Middle East becoming less attractive?
Yes, ethane cracking is less economical
No, ethane cracking is still the future
Too early to tell
