Opis:: The catalytic process of SO2 to SO3 oxidation is the main step of sulfuric (VI) acid formation. The sustained catalyst operating due to its structural and textural modifications could disturb the process course. This paper includes the influence of the vanadic catalyst worktime on SO2 emission and the expected amount of the obtained waste material of the inactivated catalyst.

Opis:: The results of the research studies concerning the reaction rate of SO2 oxidation on the vanadium catalysts have been described. A carrier of the active phase - silica has been regenerated from spent vanadium mass by leaching with H2SO4 solution. The dependence of the oxidation reaction rate on the method of treating a catalyst carrier as well as the composition of an active phase of the new catalyst systems has been also presented.

Tytuł:: Enhancement of the pool boiling heat transfer coefficient using the gas injection into the water

Opis:: In this paper, a new method for enhancing the pool boiling heat transfer coefficient of pure liquid, based on the gas injection through the liquids has been introduced. Hence, the effect of gas dissolved in a stagnant liquid on pool boiling heat transfer coefficient, nucleation site density, and bubble departure diameter has experimentally been investigated for different mole fractions of SO2 and various heat fluxes up to 114 kW/ m2. The presence of SO2 in captured vapor inside the bubbles, particularly around the heat transfer surface increases the pool boiling heat transfer coefficient. The available predicted correlations are unable to obtain the reasonable values for pool boiling heat transfer coefficient in this particular case. Therefore, to predict the pool boiling heat transfer coefficient accurately, a new modified correlation based on Stephan-Körner relation has been proposed. Also, during the experiments, it is found that nucleation site density is a strictly exponential function of heat flux. Accordingly, a new correlation has been obtained to predict the nucleation site density. The major application of the nucleation site density is in the estimating of mean bubble diameters as well as local agitation due to the rate of bubble frequency.
