Centralized vs. Point of Use Vacuum Filtration

By Jamie Stebbins, Solberg Manufacturing

In this article, we will isolate and review one system common to many plants and industries: the vacuum system. Within this system, we will further drill down to the filtration required to maintain a healthy process, which contributes directly to the bottom line. The vacuum system does not exist in many production process lines without filtration. Throughput and quality of the end product are closely tied to the necessary vacuum levels achieved when filtration is properly deployed.

Integrity Test Solutions for the Pharmaceutical Industry

By Dennis Seibert, Head of Business Development Leak Detection and by Philippe Bunod, Product Manager Integrity Solutions, Pfeiffer Vacuum

Contamination such as humidity, oxygen or microbiological ingress can impact drug stability throughout the product life cycle. To prevent the risks of stability failure of highly moisture sensitive drugs (e.g. dry powder for inhalation), or the risk of biological ingress of parenteral drugs, highly sensitive integrity tests are required. Most test methods are very challenging in regards to time, effort, complexity or the limitation of sensitivity and detection range.

Natural Gas Deliquescent Dehydrator Applications

Blower & Vacuum Best Practices® Magazine interviewed Tyler Currie, Vice President Business Development, Van Air Systems and Van Gas Technologies.

Triethylene glycol (TEG) dehydrators are the most prevalent technology for removing water vapor from natural gas . Molecular sieve dryers are also quite common in gas processing plants. Molecular sieve units have operating processes similar to industrial heat-regenerated compressed air dryers. Natural gas, however, often needs to be purified at the wellhead before reaching the processing plant. Deliquescent dehydrators are normally used, in remote locations where no power supply exists, to dry small gas volumes located between the wellhead and these main treatment plants. The most common applications are instrument gas, fuel gas, sales gas, and emissions mitigation.

Pneumatech® Biogas Dryers and ConservAir® Flow Controllers

By Richard Stukey

Energy efficiency and sustainability solutions are often associated with more obvious initiatives--such as installing compact fluorescent bulbs—but those solutions fail to dig deeper for the “hidden gems” that can have a much greater impact. For manufacturing and building engineers or anyone else dealing with high potential energy consumption and inrush current demands, compressed air systems are one of the first places to look for significant energy savings and greater sustainability.

3 Key Factors for Designing Vacuum Pump Inlet Filtration Systems

By Dan Bott

Nearly all vacuum pumping technologies have some degree of sensitivity to inlet particulate contamination. Since everything from a vacuum assisted production process ends up at the inlet of the vacuum pump, it is important to figure out how to best protect the pump in that particular environment. In many cases, the expected service life of a vacuum pump comes down to how well it is protected from incoming contamination.
