The outlet pressure of CNG filling stations is 25 MPa; what is the typical flow rate of the gas at the outlet? Thank you
Code for Design and Construction of Automobile Fuel and Gas Stations 8.4 Compressed Natural Gas Refueling Units 1 The rated operating pressure of the refueling unit shall be 20 MPa. 2 The gas filling rate of the gas filler should not exceed 0.25 m3/min (under operating conditions).
The gas flow velocity at the outlet is generally set at 8 m/s
Is there any standard basis for choosing this flow rate?
Agree with the opinion from the third floor; 8 m/s should be the economic flow velocity
As far as I know, in domestic natural gas processing plants, the flow rate of natural gas is around 8 m/s. We prepared a quote for a project, and we felt that a flow rate of around 8 m/s was too low, resulting in excessive waste of pipes; therefore, we adjusted it to 15 m/s.
The flow rate requirement should be related to pressure, right? What pressure range is suitable for a flow rate of 8 m/s? What pressure range is suitable for a flow rate of 15 m/s?
Looking at this post, only the second reply is the correct one. Outlet flow rate of the aerator, rated operating pressure. It is clearly stipulated in the GB50156 Code for Design and Construction of Gas Stations that issued by the Petroleum Industry.
