This report presents results of a field test, at an underground gas storage facility, of a new stationary leak detection system and reviews other technologies that are currently available or being developed.
A multi-phase project has developed a simplified portable analyzer emission test method for measuring NOx and CO emissions from natural gas-fired combustion sources. The method leverages the inherent linear performance of electrochemical cell-based…
This report provides status and results after completing Phase 2 of an ongoing project to develop a simplified test method for portable analyzer emissions tests. The Phase 1 report provided the technical rationale for simplifying procedures (e.g.,…
As technologies are developed to achieve lower levels of NOx emissions, the capabilities for measuring low levels of NOx become increasingly important. One potential issue is the measurement of NOx that is composed of primarily NO2. Exhaust from most…
Measurements of exhaust plume rise from a gas turbine and three compressor engines were made and the observed results were compared with predicted plume heights from existing plume rise models. Alternative plume rise models were developed based on…
The basis of electrochemical cell gas sensor technology is presented in the context of electrochemical cell portable analyzers for emissions testing of NOx and CO. This paper presents a modified test method approach and QA/QC criteria that supplement…
