"Regulatory and analyzer update for USEPA's new formaldehyde emissions limit for combustion turbines" | 2019 | Spectrum's technical team has demonstrated a <27 ppbvd Formaldehyde detection limit (DL) on its extractive FTIR equipped using a 5-meter cell pathlength. This formaldehyde detection is well below USEPA's 91 ppbvd emission threshold for Combustion Turbines now subject to regulation under NESHAP Subpa... | |

An air-assisted flare for biomass gasifiers | 2019 | Computational fluid dynamics (CFD) was used to simulate the combustion practice of the gases that produce from gasification process. In this simulation a new air-assisted flare design which capable to handle low flowrates of these gases with high performance was used. The simulated cases were perfor... | |

Flare regulatory update | 2019 | The United States Environmental Protection Agency (USEPA) revised the regulations for the refinery through the Refinery Sector Rule (RSR) revisions to NESHAP CC and UUU (aka MACT CC and MACT UUU). The USEPA is expected to propose revisions to the Ethylene MACT and the Hazardous Organic NESHAP (HON) ... | |

Multistage flameless oxidation | 2019 | Flameless Oxidation (FLOX®) is a well established low thermal NOx combustion method since the early 1990s. Flameless Oxidation can be applied for processes above self ignition temperature. Typically, switching between flame- and FLOX-mode occurs at a temperature of 850°C. This restriction can be o... | |

Neutron imaging of heterogeneous solid fuels under heating | 2019 | Solid-fuel pyrolysis, gasification, and combustion continue to play an important role in the industrial and utility sectors. Behavior of heterogeneous fuels such as biomass (e.g., wood and grasses), municipal solid waste (MSW), and coal is less understood on the micro than the macro scales, particul... | |

Remote measurement of Flare gas flow rate using a video imaging spectral radiometer | 2019 | Flares are commonly used at industrial facilities (e.g., oil and gas extraction and production sites, gas processing plants, oil refineries, and petrochemical manufacturing plants) to safely dispose of process gases (i.e. waste gases). Waste gases may be produced due to process upset or because they... | |

Simplified analysis and practical mitigation techniques for induestrial boiler thermoacoustic vibration | 2019 | Industrial boiler systems are prone to mechanical vibration which can lead to premature component failures, emission non-compliance, and greatly increased ambient noise generation. Driving mechanisms, thermoacoustic phenomena, and system geometrical interactions are complex. General methods for accu... |
