Centrifugal Spray Generator of Singlet Oxygen for a COIL

Abstract : This report results from a contract tasking Institute of Physics, Academy of Sciences CR as follows: B. Technical Proposal / Description of Work: The research on development the CentSpraySOG could not be accomplished within the previous contract duration, and therefore we would like to solve the remaining problems in order to improve still the device parameters in framework of this new contract. The work on the tasks can be described briefly as follows: To optimize the generator efficiency: to improve the Cl2 utilization at simultaneously high O2(1delta) yield. This would be attained e.g. (i) by a constructional modification of the CentSpraySOG device, enabling to vary reaction volume and so the gas residual time in the reaction space and separator at a high input Cl2 pressure, (ii) by using a more concentrated BHP, (iii) by optimizing a Cl2/He ratio at the generator input, (iv) by decreasing a diameter of the BHP droplets.
