The U.S. Department of Energy estimates that steam generation, distribution and cogeneration offer the most cost-effective energy efficiencies in the short term with potential energy savings at over 12%.
However, it is important that you ensure steam reaches the point of use at the correct quality, quantity and pressure, and that you look at some of the key areas to consider in reducing maintenance costs and energy losses, namely, the impact poor steam quality will have on the steam system and how this can be improved.
This report sponsored by Spirax Sarco takes a look at how manufacturers are meeting these challenges and seeing real energy savings.

Many companies have old DCS platforms. In computing terms, they’re ancient. Considering all that is connected and controlled by the DCS — thousands of field instruments, valves, operator interfaces and other devices working together to make the process run efficiently and reliably, having an ancient platform is flirting with disaster.
The risks are many:
- System failures
- Part availability issues
- Difficulty integrating new apps and systems
- Reduced support availability
- Operation inefficiency
While the headache of migration is sometimes too much to bear, fortunately, the DCS you install today may never have to be completely replaced because its modularity will allow it to be improved incrementally.
This white paper will detail the steps to make proper migration choices and manage the process to get more out of your DCS system.12/19/2018

Today’s manufacturing environments must heed to regulations set by OSHA’s Hazard Communication Standard (HCS) regarding combustible dusts - as part of OSHA’s Combustible Dust National Emphasis Program (NEP). Statistics show that over 1000 inspections that OSHA has completed, only 18 to 22 percent of the facilities followed OSHA requirements.
In response to OSHA’s NEP, many facility and safety managers have revamped their housekeeping practices and added industrial vacuum cleaners approved for use in Class II Div II areas to mitigate the possibility of secondary explosions caused by fugitive dust.
