Safe Every Day

One day per year, all the Air Products PRISM Membranes equipment is idled and our employees gather for a “Safety Stand Down” where we review the last fiscal year and pause to reflect on what went right. Employees from all production shifts gather together to learn new ways to work safely and then to spend some time with co-workers during a day of celebration, some games, food, karaoke, and good fun.

Our teams celebrated another fiscal year ending with no recordable injuries. This is an impressive achievement since our facility operates multiple production lines on a continuous basis. Fiber is produced 24 hours a day 7 days per week, which means that we staff multiple production shifts working around the clock. There are employees working with industrial equipment that spins, cuts, crimps, and energizes the separators throughout the manufacturing process, creating opportunities for something to go badly.


Safety is first. This is embedded in our culture and our results show that our employees are serious about working safely and helping others to work safely. Every employee is required to participate in the APT (Accident Prevention Technique) program where processes and working conditions are observed and reported, safe work practices are encouraged, and potential problems are corrected before injuries occur.

Congrats everyone. Way to stay safe!


Membrane Manufacturers Volunteer for Foster Home

Air Products PRISM Membranes employees recently participated in a Day of Caring philanthropy event with a local organization to benefit foster care homes.

Eight employees of the Prism Membranes manufacturing team volunteered their time to deconstruct an old shed and build a new shed in the backyard of a local foster home. The membranes group within Air Products is proud to support the local community and the spring weather made for a lovely day of outdoor work.

Prism Membranes Facility Hosts K-9 Training Event

The Air Products Prism Membranes facility in Saint Charles, Missouri recently assisted in a K-9 police training session. While unoccupied, the building hosted dogs and trainers from 8 local municipalities as they conducted various intruder and drug sniffing drills. The group safely utilized the facility’s office and front yard areas for certain search-and-find drills with the dogs.

Police officers at the four hour event expressed their appreciation for utilizing a different training location to offer variety in the dogs’ training sessions. Similar K-9 trials often occur in schools or office buildings on weekends. The Air Products Prism Membranes team was happy to lend their facility for this community-benefitting arrangement.

Holiday Celebrations

gifts2016aTo celebrate the upcoming holidays, the Air Products Prism Membranes employees in St. Louis Missouri donated gifts to 73 local children in need. Gifts were purchased based on the children’s wish-lists and included toys like dolls, legos, racecars, and jewelry making looms.

The celebration continued with a site-wide potluck luncheon where employees brought in their favorite dishes to share. A lighthearted trivia rivalry game followed the potluck lunch and generated big smiles.

The Air Products Prism Membranes Team celebrates their colleagues and community and wishes to extend the holiday greetings to you too!


Plant Efficiency

It’s “Photo Friday” and here is a snapshot of our new, maintenance free LED lights. We are focusing on efficiency and power reduction at our membrane manufacturing facility…and these new lights are a perfect upgrade!


Autopsying Membrane Separators (Part 2)

Autopsying Methods and Results
During our autopsy process, we look for failure modes such as broken fibers, contamination, or over pressurization. In order to investigate these failure modes, we conduct a lot of testing in our St. Louis facility’s autopsy lab. These tests often involve opening the modules, examining manufacturing consistency, and submersion testing, among many other techniques. As mentioned in last week’s ‘part one’ article, the overall goal of the autopsy tests is to identify areas where we can improve our membrane manufacturing as well as helping our customers achieve a long term, reliable membrane system performance.



Autopsying Membrane Separators (Part 1)

The Autopsying Concept and Benefits

The goal of our autopsy program is to learn about membrane failure modes both in mid service and at the membrane’s end of life. “The process is mutually beneficial for us and the customer,” said Mike Dobby. “We observe ways to improve the membrane quality and make system operation recommendations to users- to achieve the best possible performance and long membrane life.”

For years, our autopsy group has assisted in improving the quality of our membranes by indicating various findings which have led to product development strategies. See the photos below and check back with our blog next week for part 2 of the autopsying article.




70 Membrane Support Resources Available

Have you ever wondered what the inside of our membranes manufacturing plant looks like?  Do you ever wonder how to properly dispose of membrane separators? How many models of membrane dryers, nitrogen generators, or hydrogen separators do we really offer?

The answers to these questions are located in our online membranes resource center. With 11 videos and 59 membrane data sheets in our library, we cover topics like the weight restrictions of our aerospace membrane products, the differences in our biogas upgrading membrane products, and the proper way to pretreat the gas upstream of the membrane.

How Long Does the Membrane Last?

Bill Phelps, Senior Business Manager, on length of membrane life.

“I always tell my customers that it depends on the quality of the gas that they’re feeding to the membrane. We expect the membrane to last ten to fifteen years, but that’s based on the fact that they’re maintaining their compressor, maintaining filter replacements, and maintaining pretreatments to the membrane. Our product can tolerate hydrocarbon vapors, but one thing that will kill the membrane is oil being deposited on the fibers. It’s very important to super heat the feed stream to keep any hydrocarbons in the vapor stage. That influences the length of the membrane life.”
