Methanol and Dimethyl Sulfide Removal by Pulsed Corona Part I: Experiment

Abstract

Methanol and dimethyl sulfide are volatile organic compound (VOC) air pollutants that are subject of severe environmental regulations due to their toxicity, environmental persistence and odor. Traditional technologies are often inefficient for their removal, especially in the case of the dilute industrial streams. Non-thermal plasma methods, typically characterized by high removal efficiency, energy yields and good economy, offer possible alternative solutions. The present research employs pulsed corona discharge known for its high selectivity and low energy costs of emission control. This paper provides experimental (Part I) and in a later issue numerical (Part II) data on removal of methanol and dimethyl sulfide from dry and humid air streams. The removal efficiency and the specific energy input are evaluated along with the energy costs required for the removal process. Particular attention is given to the formation of unwanted byproducts such as NO x , CO, and SO 2 .

Effects of Temperature on Benzene Oxidation in Dielectric Barrier Discharges

“…Experimental data shown in this figure also suggest that the CO concentration starts to level off when SED approaching at 500 J/l, after an initial increase with SED. This result is different from the one obtained by Lock et al [15], who found that CO concentration increases monotonically with SED. On the other hand, the result shown in Fig.…”

“…Similar argument has been reported previously [16,17]. However, a strong link between the production of CO and CO 2 has also been reported in other experiments [15,[18][19][20][21]. Therefore, more detailed assessment of the experimental conditions and theoretical analysis by chemical kinetics are needed to understand this discrepancy.…”

The Role of Genetic Polymorphism and Other Factors on Clopidogrel Resistance (CR) in an Asian Population with Coronary Heart Disease (CHD)

“…Clopidogrel is a thiophene pyridine prodrug that needs to be absorbed by the intestines and transformed into active components by the metabolism of various enzymes in the liver to exert its platelet anti-aggregation effect [ 26 ]. The P-glycoprotein (P-gp), encoded by the ABCB1 gene, regulates clopidogrel absorption in the small intestine [ 27 ]. P-gp is a transmembrane protein with the primary function of pumping the drug out of the cell and into the blood circulation.…”

Gaseous Emissions from Wastewater Facilities

“…Then, water-washing and air-dilution systems were found very effective to reduce odor at the idling condition of the engine. Lock et al (2006) present experimental data on removal of methanol and dimethyl sulfide, air pollutants that are subject of severe environmental regulations due to their toxicity, environmental persistence and odor, from dry and humid air streams by non-thermal plasma methods.…”
