Emission / Leak Rate Measurement

In conjunction with optical gas imaging emission detection we also specialize in emission/leak rate quantification. The Hi Flow Sampler®, a dual-element hydrocarbon detector, is our primary method of emission measurement from leaking equipment components. The Hi Flow® Sampler is extremely reliable, efficient, and offers a high rate of accuracy (+/- 10%). This technology allows an objective cost-benefit analysis of each leak repair opportunity.

There are specific cases where the Hi Flow is not used. These cases include emissions at rates above the upper detection limit of the unit (i.e. above 10 ft3/min) and equipment in inaccessible locations.  In these cases, emission rates are measured using an appropriate flow-through measurement device (depending on backpressure tolerance of the source) such as:

• a vane anemometer,

• a rotameter, or

• a calibrated volume bag.

Accurate fugitive emission measurement enables our clients to:

• Determine cost effective repair strategies

• Make informed equipment repair decisions based on economic analysis

• Determine total fugitive emission volumes and product losses from each facility

• Effectively capture the amount of GHG emission reductions from repair activities
