Coal power stations as well as waste incinerators produce humid acid gases which condensate in industrial chimneys. These condensates may cause corrosion of the internal cladding made of stainless steels, nickel base alloys or non metallic materials. In the aim of polluting emission reduction and material optimal choice, it is necessary to determine all the phenomena which occur throughout the ...

In this work, the PC-SAFT equation of state (EoS) has been used to model the solubility of acid gases (CO2 and H2S) in two imidazolium-based ionic liquids (ILs) ([C8-mim][PF6] and [C8-mim][Tf2N]). Parameters of pure ILs were estimated using experimental densities. Two strategies were considered to model densities of pure ILs. In strategy 1, ILs were modeled as nonassociating compounds and in st...

Portable instrumentation has been developed to measure halogen acid gases inside and around armored vehicles during fire suppression tests at Aberdeen Proving Ground. This technology is used to troubleshoot for leaks, conduct area sampling, and measure occupational exposure levels of toxic gases in air. A continuous denuder extracts the gases into an aqueous medium containing the appropriate io...

soot and hydrocarbons are usually found in diesel exhaust gases. They are formed when the fuel is burnt out incompletely. Polycyclic aromatic hydrocarbons (Pah) are sorbed on the soot, and may cause cancerous diseases, asthma and other diseases. The purpose of this work was to evaluate the dependence of smoke opacity and amount of polycyclic aromatic hydrocarbons in engine emissions on multi-co...

Background: We studied in a group of patients admitted for acute severe asthma (ASA) arterial blood gases at admission and it relationship with airway obstruction. We also compared arterial gases of a subgroup of patients unable to perform spirometry because their poor clinical status with those able to complete the test. Methods. Data from arterial gases and spirometry were obtained from two p...
