Development of Emission Factors for Polyamide Processing [PDF]

Journal of the Air & Waste Management Association, 2001
Emission factors for selected volatile organic compounds (VOCs) and particulate material were developed during processing of commercial grades of polyamide 6, polyamide 66, and polyamide 66/6 resins. A small commercial-type extruder was used, and melt temperatures ranged from 475 to 550 degrees F.

Efflux of Soil Nitrous Oxide from Applied Fertilizer Containing Organic Materials in Citrus unshiu Field in Southwestern Japan

Agriculture, 2017
Nitrous oxide (N2O) emissions from agricultural fields are an important source of the increasing atmospheric N2O concentration. We conducted a two-year investigation of soil N2O emissions induced by the application of combined organic and synthetic ...

Analysis on Storage Off-Gas Emissions from Woody, Herbaceous, and Torrefied Biomass

Energies, 2015
Wood chips, torrefied wood chips, ground switchgrass, and wood pellets were tested for off‑gas emissions during storage. Storage canisters with gas‑collection ports were used to conduct experiments at room temperature of 20 °C and in a laboratory oven ...

Development of Emission Factors for Polycarbonate Processing [PDF]

Journal of the Air & Waste Management Association, 2002
Emission factors for selected volatile organic compounds (VOCs) and particulate emissions were developed while processing eight commercial grades of polycarbonate (PC) and one grade of a PC/acrylonitrile-butadiene-styrene (ABS) blend. A small commercial-type extruder was used, and the extrusion temperature was held constant at 304 degrees C.

Emission Levels and Emission Factors for Modern Wood Stoves

Chemical Engineering Transactions, 2023
The aim of this work is to recommend more correct emission factors for the modern wood stove category, based on extensive measurements carried out at SINTEF Energy Research in Norway for representative modern wood stoves. Today the best wood stoves outperform the staged air combustion wood stoves introduced in the 1990s, as further continuous ...

Crop residues integration with nitrogen rates reduces yield-scaled nitrous oxide emissions and improves maize yield and soil quality

Journal of Integrative Environmental Sciences
Maize production requires a large amount of nitrogen (N). However, a greater part of the N used gets lost to the environment as reactive forms including nitrous oxide (N2O).
