Combustion of chlorinated hydrocarbons [PDF]

open access: possible22nd Aerospace Sciences Meeting, 1984
Thermal destruction by incineration of chlorinated hydrocarbons (CHC) is an attractive method for the volume reduction and ultimate disposal of wastes. The present paper provides further insight into the fundamental properties of CHC for understanding the mechanism, rates of oxidation and other combustion characteristics, e.g., flame stability ...

Two Dimensions Numerical and Mathematical Simulation of the Transport of Hydrocarbons Chlorinated in a Porous Media

, 2014
We establish a two-dimension numerical and mathematical model to describe the transport of hydrocarbons chlorinated in the non saturated zone of a porous media. The equations are expressed in a first time at pores scale.

Chlorinated and Brominated Polycyclic Aromatic Hydrocarbons from Metallurgical Plants.

Environmental Science and Technology, 2018
In this study, we investigated several metallurgical industries, including iron ore sintering, secondary aluminum smelting, and secondary lead smelting, as potential sources of Cl-PAHs and Br-PAHs. Stack gas emissions of 19 Cl-PAH and 19 Br-PAH congeners

Secondary Copper Smelters as Sources of Chlorinated and Brominated Polycyclic Aromatic Hydrocarbons.

Environmental Science and Technology, 2017
The generation of and extent to which chlorinated and brominated polycyclic aromatic hydrocarbons (Cl/Br-PAHs) are formed and released from secondary copper smelters remain unknown.

Chlorinated Hydrocarbons in Infertile Women

Environmental Research, 1999
This study was conducted to investigate the hypothesis that chlorinated hydrocarbons (CHC) may affect fertility in women. In 489 infertile women, CHC levels were measured in whole blood. Different anamnestic and clinical parameters were obtained or investigated in order to detect possible associations to CHC concentrations.

Quantification of Degradation of Chlorinated Hydrocarbons in Saturated Low Permeability Sediments Using Compound-Specific Isotope Analysis.

Environmental Science and Technology, 2016
This field and modeling study aims to reveal if degradation of chlorinated hydrocarbons in low permeability sediments can be quantified using compound-specific isotope analysis (CSIA).

Decomposition of Chlorinated Hydrocarbons: A Review

American Industrial Hygiene Association Journal, 1972
An up-to-date review and criticism of reports on the decomposition of chlorinated hydrocarbons led to the conclusion that temperature and metal surface were prime factors in the production of phosgene, hydrogen chloride, chlorine and other decomposition products.

Chlorinated Hydrocarbons in Cetaceans

Journal of the Fisheries Research Board of Canada, 1975
DDT, PCBs, chlordane, and dieldrin levels were measured in blubber of 18 cetaceans, including humpback, sperm, dense-beaked, Atlantic, and Pacific pilot whales, and five species of dolphins. All had significant residue levels, ranging from 1.1 to 1023 ppm ΣDDT (wet weight basis), and 0.7–147 ppm PCBs. These levels are high enough to justify efforts to

Determination of chlorinated polycyclic aromatic hydrocarbons in water by solid-phase extraction coupled with gas chromatography and mass spectrometry.

Journal of Separation Science, 2016
Given the potential risks of chlorinated polycyclic aromatic hydrocarbons, the analysis of their presence in water is very urgent. We have developed a novel procedure for determining chlorinated polycyclic aromatic hydrocarbons in water based on solid ...

Estrogenlc activities of chlorinated hydrocarbons

Journal of Toxicology and Environmental Health, 1978
Some DDT analogs are estrogenic, particularly o,p'-DDT, which comprises approximately 15-20% of the commercial DDT mixture. Whether this compound or its metabolites are active has not been established. In fact, the data obtained thus far are more confusing than enlightening.
