Formaldehyde Emissions from Dry Low Emissions Industrial Gas Turbines
Volume 3B: Combustion, Fuels, and Emissions, 2022Abstract Formaldehyde is listed as a Hazardous Air Pollutant (HAP) by various regulatory agencies around the world because of its role as a carcinogen. To address this impact, several countries have regulated formaldehyde emissions from land-based gas turbines. In the United States (U.S.), the federal regulatory level is 91 ppb and state

Formaldehyde surface emission monitor
Analytical Chemistry, 1984A passive surface emission monitor has been developed for nondestructive measurement of formaldehyde (CH/sub 2/O) emission rates from CH/sub 2/O resin-containing materials such as urea-formaldehyde foam insulation (UFFI) and pressed-wood products. Emitted CH/sub 2/O is sorbed by a planar distribution of 13X molecular sleve supported inside the monitor ...

Formaldehyde emission from particleboard
Holz als Roh- und Werkstoff, 1981A test method is described and experimental data are presented which compare formaldehyde emissions from edges and surfaces of particleboards. Surface emissions from boards of different structures and resins are also presented. Porosity of particleboards was measured and related to formaldehyde emission.

Production of melamine fortified urea‐formaldehyde resins with low formaldehyde emission
Journal of Applied Polymer Science, 2011AbstractMelamine can be incorporated in the synthesis of urea‐formaldehyde (UF) resins to improve performance in particleboards (PB), mostly in terms of hydrolysis resistance and formaldehyde emission. In this work, melamine‐fortified UF resins were synthesized using a strong acid process.

Reduction of formaldehyde emission from plywood
Journal of Adhesion Science and Technology, 2013The aim of this work is to evaluate performances of tannin-based resins designed as adhesive in the plywood production. For this purpose, a part of phenol formaldehyde (PF) and melamine formaldehyde (MF) in the classic adhesive formulation was replaced by tannin. The physical properties of the formulated resins (rheological characterization, etc.) were
