Paper Abstract

The mechanism of Cl2 absorption and O2(1(Delta) ) generation in JSOG were considered. The concentration of oxygen dissolved in BHP can in 103 times more than equilibrium oxygen concentration. But it is not enough for spontaneous generation of oxygen bubbles. The 'burying' of oxygen into bulk of BHP occurs during macroscopic renewal of BHP surface. It was found that this effect doesn't result in essential O2(1(Delta) ) yield decreasing. Three dimensionless criteria have been derived from one-dimensional model for dynamic scaling of JSOG. The approximate values of these criteria were calculated to achieve 90% Cl2 utilization and 60% O2(1(Delta) ) yield. The measurements of Cl2 utilization and O2(1(Delta) ) yield from JSOG allowed to make more precisely these three criteria. It was found that the rate of chlorine absorption in JSOG is higher than it follows from one-dimension model. It was explained by hydrodynamic renewal of surface of BHP jets. The O2(1(Delta) ) yield from JSOG is less than calculated according to one-dimension model. It was explained by additional unknown reactions in reaction zone of JSOG. The dimensionless criteria can be used for the first step of scaling of JSOG. The droplet content at the exit of JSOG with vertical gas outlet is expected to be less than in JSOG with side gas outlet. The Verty-JSOG with initial Cl2 flux 8 mmole/s/cm2 is projected.
