Vapor & Biogas
Services

At John Zink, we specialize in optimizing your systems for peak efficiency, backed by our commitment to providing round-the-clock support and our extensive OEM experience. We’re your ultimate service partner, offering comprehensive solutions for all your vapor and biogas service needs.

 

Commissioning & Start-Up

Commissioning landfill flares, vapor recovery units, and vapor combustion units is a meticulous process crucial for effective gas emission management in landfills and terminals. Compliance with environmental regulations and safety standards is paramount. Our extensive expertise in this field, coupled with a strong commitment to industry guidelines and safety protocols, makes us the top choice for all your commissioning needs. We ensure these systems function efficiently, minimize emissions, and operate safely.

Maintenance & Troubleshooting

Preventative Maintenance Plans


A regularly scheduled and properly performed Preventative Maintenance (PM) program by our service technicians can help you reduce unplanned downtime, avoid possible emergency callouts, ensure maximum availability of your equipment and extend equipment life under optimum process conditions.

Troubleshooting

Facing challenges with your vapor and biogas systems? Let our expert technicians diagnose and rectify them for you. Leveraging years of industry experience, expert knowledge, and state-of-the-art engineering tools, we offer prompt issue resolution, minimizing downtime and quickly restoring operations.

 

With tools like InSiteTM available, our team can remotely access the PLC and HMI for more effective and efficient troubleshooting when necessary.

 

Activated Carbon Degradation

A common source of increased emissions and decreased performance from vapor recovery systems is activated carbon degradation. John Zink offers two services to address this problem: our innovative BWC Boost™ process and carbon replacement. Before either can be recommended, we provide comprehensive carbon sampling and testing. This measures the condition of your carbon and determines whether the carbon is in good condition, is a candidate for BWC Boost, or requires a full carbon replacement.

BWC Boost

BWC Boost is a John Zink-exclusive process that can raise the Butane Working Capacity (BWC) of your carbon. Developed specifically to increase the life span of the activated carbon in a vapor recovery unit (VRU), the process requires less downtime and cost than full carbon replacement. For carbon with a low BWC grade and little or no dust content, the BWC Boost process removes hydrocarbon residue trapped in the carbon bed without removal or replacement of the carbon itself. Testing shows typical improvement to a BWC B grade on a variety of carbon conditions.

Benefits:

  • Restores carbon to a higher BWC
  • Extends carbon life
  • Improves performance (BWC and emissions capture)
  • Requires less downtime (2 to 3 days compared to 5 for carbon change out per standard VRU)
  • Does not require the disposal of spent carbon

Refractory Replacement

Proper refractory is crucial for maintaining high temperatures, improving energy efficiency, ensuring safety, reducing emissions, and optimizing the overall performance of industrial combustion systems while protecting the stack’s structural integrity. As a critical component of these systems, replacing refractory in your stack is a complex and highly specialized task. John Zink’s team of experienced professionals is ideally equipped for the job, ensuring not only safety but also efficiency and compliance with industry standards. Our skilled technicians are on-site throughout the entire process, overseeing tasks ranging from lockout-tagout procedures to restarting the unit once the work is completed.

Carbon Replacement

John Zink can also provide turnkey service to replace the old activated carbon with new, virgin activated carbon. After several years of service, the activated carbon in VRUs can mechanically degrade over time and create dust. This dust can cause contamination and plugging of other processes in the VRU and potentially cause the channeling of vapors due to the compaction of the fine carbon particles. Completely replacing the carbon removes the dust from the system and provides a fresh start for the VRU.

 

Carbon replacement projects typically include the following:

  • Remove the old activated carbon from the VRU
  • Inspect and clean the interior of the carbon vessels including the carbon support screens
  • Make minor repairs to carbon support screens if necessary
  • Install new activated carbon into the vessels
  • Perform a saturation to establish a hydrocarbon heel on the new carbon
  • Place VRU into a cleanup mode and fine-tune the system to ensure proper operation
  • Place unit back into normal service

 

Benefits:

  • Eliminates dust from carbon vessels which can mitigate various issues with the VRU
  • Provides a fresh start with virgin activated carbon
  • Provides an opportunity to upgrade your carbon type with the highest working capacity available in today’s market
  • While VRU is down, provides an opportunity for seal fluid flush for liquid ring VRUs or other maintenance activities and upgrades that cannot be performed during normal quarterly maintenance
