Carbon Dioxide Dosing System Typically a CO2 dosing system contains following components: - CO2 Storage Tank(s): The storage tanks are fully insulated mild steel pressure vessels. The CO2 is stored at around 300 psi & (-) 20C. A complete automatic refrigeration system is provided to maintain storage tank at (-) 20 C and 300 psi. The tank is complete with filling/withdrawal lines & necessary instrumentation for safe operation. - Vaporizer/Vapour Heater: A Vaporizer is provided to vaporize the liquid CO2 to gaseous state as per requirement. Vapour heater is provided to heat (-) 20C CO2 to near room temperature. Both Vaporizer & vapour heater are provided with necessary safety and measurement instrumentation. - CO2 Regulator: Carbon dioxide pressure reducing regulator is provided each storage tank, which is mounted in the CO2 pipeline after dioxide vapor heater. Each regulator shall be used to reduce the pressure from approximately 300 psig to 100 psig. The outlet pressure of each regulator shall be easily adjusted through the use of an adjustment screw. - CO2 Diffusers: A set CO2 gas diffuser assembly with tube type fused alumina, porous, fine bubble diffusers are provided to input carbon dioxide into the re-carbonation basin.
