After investigation, it’s determined that air pulse noise generated when canister purge solenoid valve is working, it transmitted to panels through pipeline, and then cockpit, which would cause sound. By adding expansion chamber desorption pipe d...

The effect of the duration adsorption step and purge flowrate on performance a demand-driven pressure swing unit (PSA) was investigated. These two operating parameters were varied examined by simultaneously varying requested total productivities (demand) using model for biogas upgrading. considered PSA application uses FAU zeolite (13X) to separate CH4 CO2. is tracked three key indicators (KPIs...
