RTO for Landfill RNG Upgrade Tail Gas Emissions

Jan 28, 2025 11:25:23 AM

Catalytic Products International (CPI) installed a 10,000 SCFM Regenerative Thermal Oxidizer RTO for a renewable natural gas (RNG) developer who constructed a landfill gas upgrading facility to convert municipal solid waste landfill gas into pipeline‑quality renewable natural gas. The facility uses membrane separation, adsorption, and nitrogen rejection technologies to meet pipeline specifications for methane content and heating value.

Controlling Fugitive VOC Emissions: EPA Method 204, Capture Hooding, PTE & TTE

This article was updated in July 2026 to reflect current EPA Method 204 guidance.

Fugitive VOC emissions are the uncontrolled release of gases to the atmosphere — vapors that never make it into a control device at all. A well-built thermal oxidizer, RTO, or catalytic oxidizer routinely destroys 95–99%+ of the VOCs that reach it, but that destruction rate only counts toward your permit if the emissions actually get there.

Overall control efficiency is: Overall Control (%) = Capture Efficiency (%) × Destruction Efficiency (%) ÷ 100

If your capture system is only 70% effective and your oxidizer destroys 98% of what reaches it, your overall compliance number is 68.6% — often not enough to satisfy a permit limit. This is why fugitive emissions are frequently the single largest source of uncontrolled VOCs at a facility, and why regulators require a documented, tested capture strategy before crediting your oxidizer's destruction rate at all.

Controlling Fugitive Emissions, Part 3: Temporary Total Enclosure

Fugitive emissions are what we call the uncontrolled release of gases into the atmosphere. This is something that happens regularly; in fact, fugitive emissions can be released when we fill our cars' gas tanks. The air that is displaced inside a gas tank that is being filled causes hydrocarbons in the form of gasoline vapor emissions to exit from the fill spout into the atmosphere in an uncontrolled manner. Some states seek to limit these fugitive emissions by requiring gas stations to use "Vapor Recovery" nozzles which capture this vapor and return it to the gas station's underground gasoline tanks, reducing the "loss" of gasoline and creating less air pollution.

Fugitive emissions are the uncontrolled release of gases into the atmosphere. This is something that occurs regularly; in fact, it often happens when we fill our cars' gas tanks. The air being displaced inside the gas tank when it is being filled causes gasoline vapor emissions (hydrocarbons) to exit into the atmosphere in an uncontrolled manner. However, some states do require the use of "Vapor Recovery" nozzles to capture these vapor emissions and return them to the gas station's underground gasoline tanks, where the vapors become liquid again, reducing the "loss" of gasoline and creating less air pollution.

Controlling Fugitive Emissions, Part 1: Close Capture Hooding

Fugitive emissions, in their simplest form, are the uncontrolled release of gases to the atmosphere. Each one of us may contribute fugitive emissions when we fill our automobile gas tanks. The displacement of air inside the gas tank causes gasoline vapor emissions (hydrocarbons) to exit out the fill spout (un-controlled) to the atmosphere. Some states require the use of "Vapor Recovery" nozzles which capture the vapor emissions, returning them to the underground gasoline tanks. The vapors then become liquid again, reducing the "loss" of gasoline, as well as removing hydrocarbons from the air, which means less air pollution.
