Linde North America announced today the publication of a white paper to help oil and gas operations determine the most efficient and cost effective method to control the emission of volatile organic compounds (VOCs).

This, in turn, will enable them to reduce the environmental impact of their VOC emissions and comply with air quality regulations.

The white paper, Solutions to Contain VOC Emissions and Comply with Evolving EPA Regulations, is available as a free download on Linde’s website:

The white paper addresses an update that the Environmental Protection Agency (EPA) issued in August 2013 to its 2012 New Source Performance Standards for oil and gas producers. The update states that storage tanks used in oil or natural gas production and transmission, and have the potential to emit six or more tons of VOCs a year, must control VOC emissions by 95% within a certain timeframe.

This update has led many operations to re-evaluate their methods for controlling VOC emissions. Some may need to quickly implement a solution to comply with this new regulation, 40 CFR Part 60, by April 2014.  

Linde has found that using cryogenic condensation (also known as “cryocondensation”) to meet the EPA regulation can be a safe and cost-effective method to significantly reduce VOC emissions, particularly if a facility recovers and re-routes VOCs emitted or reuses the vaporised nitrogen.

“Cryocondensation may be an ideal and low-cost solution for an oil or gas operation that needs to comply with the EPA’s regulation quickly,” explained Leslie Waller, head of the Chemistry Industry at Linde North America and one of the paper’s authors.

The white paper suggests that cryocondensation may be a better way to control VOC emissions at the point of use when compared to other solutions, not just to meet EPA Regulation 40 CFR Part 60, but also to demonstrate compliance with new and updated regulations.

The white paper outlines some of the challenges of meeting air quality regulations and lists the potential methods to controlling VOC emissions as well as the benefits to capturing those emissions. It also offers details on how a facility can choose the right solution, including the experience and technology needed to successfully install cryocondensation systems or other abatement technologies for controlling VOC emissions.
