Cimarron’s technologies are employed to capture and/or combust excess biogas that cannot be utilized or stored, ensuring safe disposal while minimizing emissions. We partner with developers, EPCs, and operators on methane emission control, beneficial use, and renewables projects to provide gas treatment solutions as well as controls integration.
Our engineering team are experts in biogas collection and control and are available to support our customers when they need assistance. Beyond initial sizing of the equipment, we can model new conditions with process simulation software, calculate hydraulics, and perform other studies, to support field operations.
We have a dedicated in-house service team with extensive biogas commissioning, operating, and troubleshooting experience across the US. Cimarron provides the following aftermarket and engineering services: Start-up, Commissioning, Installation Supervision, Emergency Troubleshooting and Repair Support, Preventative Maintenance Services, Spare Parts, Retrofits & Upgrades, Automation, Realtime Monitoring, Engineering Support / Site Surveys, Air Source Testing, I&E Solutions.
Cimarron utilizes in-house equipment fabrication at several different manufacturing shops. By eliminating the reliance on third party vendors, Cimarron can ensure the quality of the equipment and minimize lead times. Our strategically located manufacturing locations provide flexibility by allowing us to distribute work across multiple shops and ensure proximity to our customers with reduced freight costs.

Biogas is a renewable energy source produced through the anaerobic digestion or fermentation of organic materials such as agricultural waste, food waste, landfill waste, and wastewater. Biogas contains greenhouse gas impurities which require monitoring and destruction via combustion.
Every landfill gas operator in the U.S. is now faced with addressing the issue of the gas produced by the landfill during the decomposition of organic matter residing in the landfill. The U.S. Environmental Protection Agency has set emission limits and thresholds for the landfill industry. When exceeded, landfill gas must be controlled (collected or flared) and may no longer be vented to the atmosphere.
Landfill gas is typically composed of 50% methane (CH4) and 50% carbon dioxide (CO2). Many landfills in North America have already been required to install a gas gathering system to collect or flare the gas rather than allowing it to vent to the atmosphere. Typically, this collection system consists of wells bored into the landfill to capture and route the gas to a gas handling system. From the wells, Cimarron’s blower packages route landfill gas to either be destroyed by Cimarron flares, or to be further processed for other beneficial uses.
Landfill Gas Secondary and Advanced Treatment: In secondary treatment applications, landfill gas may be utilized to power gas engines or turbine driven generator packages. These systems create electricity to supplement onsite electrical needs or to be sold to the power grid. In advanced treatment applications, gas plants process the gas (through membrane systems, chemical systems, or pressure-swing absorption systems) creating pipeline quality methane (biomethane) for beneficial uses including pipeline injection and vehicle fueling. Depending on the use of the gas, Cimarron designs and builds various flare and compression systems to handle the gas plant’s needs. These systems can handle a variety of gas pressures and compositions covering everything from low to high BTU applications. Cimarron’s standard equipment can be customized to handle any specifications or requirements.
Equipment Designed for Challenging Conditions: Landfill gas units must be designed to combat the destructive effects of a water saturated, high carbon dioxide (CO2) gas stream. As required, Cimarron units are equipped with HDPE (HighDensity Polyethylene) or stainless-steel piping, knock out pots, and valve trims to handle the corrosive nature of the gas. In addition, Cimarron provides mist eliminators, knockout pots, dehydrators and various other liquid condensing equipment to remove water vapor from the gas stream. Despite sophisticated controls, all Cimarron units are designed for ease of maintenance, and years of trouble-free service.
Landfill Combustion: Because not all the gas generated by a landfill can be captured, Cimarron also has an array of flare and thermal oxidizer solutions to prevent venting methane to the atmosphere. Flaring devices are needed as a backup emergency solution when the gas plant is down (e.g. during planned maintenance). Thermal oxidizers are required to destroy tail gas that is not captured by the gas plant. Cimarron offers various flare and thermal oxidizer solutions ranging from 98 to 99.99% destruction and removal efficiency (DRE). All flares and thermal oxidizers systems are designed to handle your challenging gas and environmental conditions.
Many segments within the food and beverage industry are becoming more and more attuned to reducing their carbon footprint. From food processing plants to regional breweries, gas recovery and flaring solutions from Cimarron are an efficient way of maintaining environmental compliance or integrating with energy recovery programs to power a facility.
Cimarron has extensive experience capturing biogas emissions from brewery operations. The methane gas produced by the fermentation process is captured and directed to electric generators. These electric generators are then utilized to provide power for a significant percentage of the brewery.
Farms across America are discovering that the gases produced from the organic waste of livestock are not only harmful to the environment, but they can also be a missed opportunity to fuel the facility. Through the capture and/or flaring of methane, agricultural facilities are able to reduce their carbon footprints, meet or exceed government regulations and/or integrate with energy recapture programs for the facility.
Cimarron’s Gas Collection and Control Systems (GCCS) are fully assembled, skid-mounted systems are engineered systems used to extract, compress, and transport biogas from various sources, such as landfills, wastewater treatment plants, or anaerobic digestion facilities to the end device such as an elevated flare or enclosed combustors. These systems are engineered to maintain precise flow and pressure levels, with automated control achieved through integrated pressure sensors and variable frequency drives (VFD).
Key Features of Cimarron’s Biogas Collection and Control Systems:
The primary information needed to size Biogas equipment is the flow, composition, available pressure, and performance or application requirements. This information is then used to determine the size of the moisture separators, blowers/compressors, and heat release for a combustion device.
Notes:
Our enclosed flares are sized based on heating value and vary depending on desired technology. Our systems vary from ultra-low emissions to non-temperature controlled units for a low-cost option to shroud the flame.
