The Reduction in the Number of CO2 Defects in the Process of Obtaining Breathing Air for Hyperbaric Oxygen Conditions

Maintaining a stable carbon dioxide content in the process of obtaining breathing air is essential for safe underwater operations and the reduction of the cost of losses resulting from a poor quality product. The paper addresses the modification of the hyperbaric breathing air production process in terms of eliminating harmful carbon dioxide contaminants. It presents the effects of the modifications made to the process in order to minimise the proportion of defects. A description is given of the status of the process before and after the correction in terms of the identified areas of improvement leading to the achievement of the defined critical requirements of the process. Achievement of the objective to rationalise the breathing air production process was confirmed by results of tests carried out at KTPP AMW¹ based on the compressed air supply system of the DGKN - 120 complex².
