One of the most exciting technologies impacting the ability of end-users to optimize blowers at their wastewater treatment plants and manufacturing operations is controls. Blower & Vacuum Best Practices interviewed Tim Hilgart, of Howden America, to get his perspective on blower controls technology and its application.
By using state-of-the-art vacuum technology for degassing mineral water, it has been possible to save an average of 3,000 cubic meters of water per filling plant per year. The solution was to replace the existing liquid ring vacuum pumps with MINK claw vacuum pumps from Busch Vacuum Solutions.
The 2019 WEFTEC Technical Exhibition and Conference was held September 23-25 at McCormick Place in Chicago. The event featured 148 technical sessions, 27 workshops, 16 mobile sessions, seven local facility tours and 1,000+ exhibitors. Both Blower & Vacuum Best Practices and Compressed Air Best Practices® Magazines were pleased to be in the literature bins at the 2019 WEFTEC!
Distillation, degassing, drying, filtration, membrane separation, adsorption, and crystallization are all among the separation processes that rely on the differences in the physical properties of substances in a mixture. Distillation relies on the differences in boiling point or in vapor pressure versus temperature characteristics. Heating, evaporation, and condensing are the tools used in distillation that separate the liquid constituents in a liquid mixture.
A major challenge our customers face is the way bulk materials are supplied to the market. We needed a material handling system that would keep up with our demand, ensure worker safety and limit manual manipulation of material. The VAC-U-MAX team designed and manufactured a material handling system capable of conveying over four and half million pounds of powders per year that now allows us to continually meet our growing business.
In the first of this two-part series on the basics of aeration control valves we examined valve fundamentals and basic equations for analysis. Here, we look at interactions between valves and discuss new flow control technologies.
In 2010, the American Society of Mechanical Engineers (ASME) established the PTC 13 Committee to establish a power test code for all blower technologies. Blower & Vacuum Best Practices Magazine interviewed Committee Chair Jacque Shultz, HRO-Turbo Product Technical Leader, Howden North America, Inc., for an update on the new code.
Sizing, selection, and adjusting control valves often causes confusion for process and control system designers. Improper valve application can cause operating problems for plant staff and waste blower power. Basing the airflow control system design on fundamental principles will improve valve and control system performance.
Blower systems designed to deliver continuous airflow at pressures of 50 psig or below are critical to the operation of many processes including wastewater treatment, pneumatic conveying, fluid catalytic cracking, and fermentation to name a few. Many circumstances could arise that require an operator to require a rental blower for a period.
Efficiency compares the inputs used by a system to the outputs produced. It is a commonly used concept, but one which is prone to a great deal of misuse in many industries. This article provides insight into the parameter known as “efficiency,” how it’s calculated, and importantly, it’s uses and limitations in predicting blower energy consumption and comparing alternate system designs.
Blower & Vacuum Best Practices interviewed Deepak Vetal, National Sales Manager, Blowers and Low-Pressure Compressors, Atlas Copco Compressors, LLC.
To put it in perspective, the food and beverage industry accounted for 12 percent of the U.S. gross domestic product in 2017. The main subsegments that use low-pressure air for numerous applications in this industry include meat processing, poultry, dairy product manufacturing, preserved fruits and vegetables, as well as brewing and beverage processes.
