The GasTechno® Process

The GasTechno Process

Skipping the Synas Step
Traditionally, natural gas is reformed into syngas, and then further converted into methanol and other liquid chemicals or fuels. The process is complex and requires high-maintenance catalysts and massive economies of scale to be profitable. Most natural gas sources are simply too small to apply syngas technologies. For these applications the GasTechno process is the only option.

The GasTechno process eliminates the syngas step and associated catalyst by converting methane directly into methanol via a patented direct homogenous partial oxidation process. The GasTechno system featues an energy-neutral recycle loop where unreacted methane is scrubbed and recycled until the desired conversion is achieved. The carbon and thermal efficiencies of the resulting process are comparable to syngas-based technologies.

Subject to certain assumptions, the process generates 6.2 gallons methanol, 5.1 gallons formalin and 0.4 gallons ethanol per 1 mscf of methane feedstock. These valuable commodities are easily collected and marketed, mitigating the risk associated with volatile natural gas prices.

Scalable to 30 mmscfd as One Production Train
The scalability of the GasTechno process has been independently validated up to 30 mmscfd as a single production train. As with liquefied natural gas (LNG) systems, multiple trains can be installed to achieve larger economies of scale.

Catalyst Free for Rich and Off-spec Gases
Because GasTechno uses no catalysts it has a high tolerance for common contaminants without costly pre-treatment. The process is relatively insensitive to nitrogen and carbon dioxide, and accepts sour gas without significant adverse effects. In almost all cases, from gas produced at biodigesters and landfills to associated gas flared at oil wells, the process accepts methane "as-is."

Tolerance of Select Components

"I can confidently state that this one step technology of converting natural gas to methanol, will alter the technology view which currently exists in the major chemical and petroleum industry..."
