Abstract The mechanism of air pollutant generation during combustion of gaseous fuels is simulated with ASPEN Plus process simulator release 9.1 -3 (1994). Based on the concept of minimization of total Gibbs free energy of the system, adiabatic flame temperatures for several stoichiometric fuel/air mixtures are calculated. Analysis of combustion products including air pollutants with concentrations as low as 1 ppb is carried out and compared with previous works. Sensitivity analysis to study the effect of changing reaction temperature and fuel/air ratio on pollutant concentrations are also carried out and the results are discussed. Detailed tables and various graphical resul ts are presented, demonstrating the powerful capabilities of ASPEN Plus in combustion modeling and air pollution studies.

Abstract Design of an electrochemical adsorption cell utilising Reticulated Vitreous Carbon [RVC] as the working electrode, stainless steel as the counter electrode and a cellulose acetate membrane separator for the sepa ration of 5.4 um polystyrene latex colloidal particles from a KCI solution is described. Effect of variation of flowrate and electrolyte concentratio on the rate of deposition is investigated and the results are compared with Derjaguin-Landau-Verwey-Overbeek [DLVO] predictions for the occurrence of favourable and unfavourable deposition conditions.
