As the first bottle-to-bottle recycling facility in the state, Momentum Recycling in Broomfield is a significant asset supporting the environmentally responsible mindset that has become a hallmark of Colorado lifestyles. Glass recycling can reduce about 5 percent of the waste stream which means less landfill space is needed. Thanks to Momentum, 85 percent of recycled glass in Colorado goes back into new bottles.
Yet, recycling glass is no simple task. The process is a complicated industrial procedure which includes several filtering steps of materials.
That’s the theme realized by Momentum after the plant had been open about a year. Questions were raised about the performance of their compressed air equipment. They turned to Blackhawk Equipment, and a compressed air audit was performed for the facility. The Blackhawk audit team quickly realized tremendous opportunities to optimize for both equipment performance and energy savings. Blackhawk was able to get Momentum Recycling a significant rebate through the Xcel Energy Rebate Program. Here are the main updates and adjustments they made through our recommendations and service:
This customer wanted Blackhawk Equipment to conduct a compressed air system audit, due to our expertise in the metal beverage industry. They had just finished a project with another vendor that ended up with no energy savings or incentive, but still believed efficiency improvements and energy savings were possible.
Blackhawk Equipment worked with Xcel Energy and decided the path forward included a “self direct” program due to the higher incentives offered. Working with Xcel, Blackhawk developed a Measurement and Verification plan specific to the customer and that would satisfy Xcel Energy’s requirements.
The plant ran 7 - 600 HP centrifugal compressors and 1- 1000 HP compressor. The units were very old and inefficient. The controls of the individual machines did not efficiently work together, but given the age of the equipment, new controls and massive overhauls were not ideal.
After measurement and data analysis, we recommended a single 1,750 HP compressor to replace the 7-600 HP units. The project was accepted and approved by the customer and Xcel energy. The customer made a few process changes and the new compressor was installed.
We completed a post-project measurement and verification process and discovered the customer was saving in excess of 931 KW (1,247 Horsepower). Xcel Energy paid out an incentive of $684,000.00 on this project.
The customer’s existing system was out of capacity, so they called on Blackhawk Equipment to conduct an air audit and recommend an energy efficient replacement compressor to meet their growing compressed air needs.
The existing air system supplied air for the manufacturing lines located in the GPT industrial complex for the manufacturing of piping flange gaskets. The system was comprised of one 30hp fixed speed oil flooded rotary screw compressor. The system has one compressor room which also contained an air dryer and receiver tank. Observed end uses were regulated, and pressures varied.
The air audit returned the following data:
Based on the findings of the audit of the compressed air system Blackhawk Equipment recommended the following:
Upon repair of the leaks found in the system and the installation of the 50hp VSD compressor, Blackhawk Equipment was able to secure an Xcel Rebate of $6,137 as an incentive to purchase the VSD compressor and provide a 2.93 year payback of the new VSD compressor in energy savings. All of this was accomplished by stabilizing system pressure and increasing the minimum pressure of the plant during periods of peak flow.
