More than 300 million tons of plastic is produced every year, and much of it ends up causing environmental problems. In response to these challenges, there are widespread global efforts to increase recycling capacity and innovate for more efficient and effective recycling solutions. Vacuum plays a critical role in achieving these improvements.
The plant recorded another win in its long list of accomplishments when it replaced aging multistage blowers with high-speed integrally geared blowers in 2020. The new blowers with Variable Frequency Drive (VFD) control are credited with a 40% reduction in energy consumption for aeration. This results in an annual savings of $35,000. The blower upgrade, which also helps protect the safety of employees, is expected to deliver a payback of less than five years.
Nowadays, pneumatic suction conveying is an important technology for feeding bulk goods gently through piping systems to the various process steps. In the area of food processing, the pharmaceutical and chemical industry and for material feed in plastics processing, suction conveying is indispensable when powder or granular materials have to be transported. The proper choice of the vacuum generator essentially determines the operating costs of a pneumatic conveying system.
The American Society of Mechanical Engineers (ASME) released their Wire-to-Air Performance Test Code for Blower Systems in 2018. Designated PTC 13-2018, it has rapidly become a standard for inclusion in blower specifications.
