Buffalo Creek Renewables

  • Iowa Park, Texas
BACKGROUND
Located on the Buffalo Creek Landfill in Iowa Park, Texas, this project was commissioned in 2024. We designed a Selexol system with a capacity of 2250 scfm. This will convert up to 98% of the methane captured for injection into the local gas transmission system.
The facility now has a 5:1 turndown ratio capable of treating a wide band of inlet flows without sacrificing efficiency nor requiring major upgrades as the landfill grows and gas production increases.
We were able to utilize our in-house construction team to complete a full wellfield buildout. We drilled and completed 84 wells, installed over 4 miles of six, eight, twelve, and eighteen inch pipe with headers, 8 sumps, and over 10 miles of air and water lines.

Weatherford Renewables

  • Weatherford, Texas
BACKGROUND
Weatherford Renewables is located on the Waste Connections Weatherford Landfill in Texas. Waste Connections previously installed a small wellfield with a header system for odor control. We were commissioned to convert the site in November of 2024.
The facility utilizes Selexol with a design capacity of 2250 scfm. The system well convert up to 98% of the methane into RNG for injection into the local gas transmission system. An H2S solid media and O2 reactor were paired with the Selexol system to meet the requirements for converting the raw gas to pipeline quality RNG. The facility has a 3:1 turndown ratio capable of treating a wide band of inlet flows without sacrificing efficiency. The design allows for easy expansion as the landfill and related gas production increases.
Our expert construction crew performed a complete wellfield buildout. The crew drilled and completed 74 wells, installed over 2 miles of four, six, eight, twelve, and eighteen inch pipe and headers, 4 sumps, and over 4 miles of air and water lines.

Hinton Regional Landfill

  • Garland, Texas
BACKGROUND
In 2020, Morrow Renewables hired construction teammates that later would form MPS to build one of the most efficient and state of the art facility to date with a design flow of 5,500 scfm. The MPS team utilizing stock equipment packages and redesigned for significant increased efficiency, operability, and increase of automation. These key changes led to MPS’s standard equipment packages for RNG solutions.
The LFG on site is refined into high-BTU RNG at this facility. Nitrogen removal is not required, as the developer’s landfill operations maintain wellhead nitrogen under 0.75%. Condensate at this project is stored in onsite tanks and pumped back to the landfill’s leachate system. RNG from the Conversion System is metered and sold to Atmos Energy Corporation’s (Atmos) local natural gas pipeline.
Prior to MPS starting the project, the inlet raw gas flow was 1,400 scfm from the landfill. MPS crews installed 87 vertical wells to transition the landfill to NSPS compliance prior to the plant installation, and once the project was operational, the developer immediately expanded the wellfield, drilling more than 66 vertical wells and six horizontal wells.

Benefits of MPS Technology

Much larger operational range.

Our plants are built with a standard 3:1 turndown. With additional compression, they will also turnup 3:1.

Continuous operation at the best efficiency point.

Least amount of compression required.

Minimal upfront gas conditioning required.

Very tolerant of process upsets and contaminants that would destroy other technologies.

No equipment or media changeouts are required if excessive contamination does occur in the solvent. Just drain the system and refill it.

All equipment items are all standard oil and gas components. There are no specialty items required for MPS’s Selexol packages. This makes finding spares or replacements easy, minimizing downtime.
