Field experiment was laid out in a split plot design with three varieties of rice. Rice samples were exposed to sulfur dioxide at different concentrations inside fumigation chamber. After measurement rice canopy reflectance spectrum, leaves of rice canopy were sampled to analyze physiological characteristic. The investigation mainly focuses on four parts. (1) SO2 concentration was significantly...

The modelling of the in-duct desulfurization process at low temperatures was performed from data obtained in an entrained flow reactor at laboratory scale. Two modelling approaches were used for the process description under in-duct conditions in the reactor: (i) the application of the grain model to a single particle along the reactor, and (ii) a non-ideal adsorption equation for the gas–solid...

BACKGROUND Air quality degraded by black smoke (particulate matter, PM10), sulphur dioxide (SO2) and nitrogen oxide (NO(x)) affects human health. Improvements following national legislation have lowered death rates. Whether background air pollution levels continue to affect human health remains unclear. AIM To determine impact of air pollutant concentrations (PM10, SO2 and NO(x)) on in-hospit...

A large number of studies have indicated associations between particulate air pollution and adverse health outcomes. Wintertime air pollution in particular has been associated with increased mortality. Identification of causal constituents of inhalable particulate matter has been elusive, although one candidate has been the acidity of the aerosol. Here we report measurements of acidic aerosol s...

The aim of this work is to investigate the influence of NO/SO2 on the emissions of N2O from diesel engine. A direct-injection diesel engine (model NF-19SK YANMAR) one cylinder was employed to test the emission. This engine works on fourstroke cycle and was operated at 2200 rpm by 25, 50, and 75% engine load. The experiment by three level sulfur content of fuel by adding DBDS into MDO and experi...

This work deals with modeling and simulation of SO2 removal in a ceramic membrane by means of FEM. A mass transfer model was developed to predict the performance of SO2 absorption in a chemical solvent. The model was based on solving conservation equations for gas component in the membrane. Computational fluid dynamics (CFD) of mass and momentum were used to solve the model equations. The simul...

A dynamic method was developed for kinetic model parameter estimation of ascorbic acid degradation during air-dehydration of pretreated (sucrose and sulphiting pretreatments) pineapple slices. Pineapple slices were pretreated in sucrose solution of 40% and 60% and SO2 solution of 1500ppm and 2500ppm SO2 respectively before air-dried in a cabinet dried for 10h at 700C temperature. Ascorbic acid ...
