Gas Orifice Plate Calculation


Gas Orifice Plate Calculation
Determine Gas flow rate for the following conditions:

  • Gas flowing temperature = 84 °F
  • Gas flowing pressure = 1014 psig
  • Gas specific gravity = 0.65
  • H2S and CO2 are not present
  • Base pressure = 14.73 psia
  • Base temperature = 60°F

The meter run will be installed at the base of a glycol contactor, where the piping shall include two
ells in different planes.

1. Flange taps are required
2. Carbon steel flange material and 316 stainless steel orifice plate will be acceptable
3. Bellows type manometer will be used
4. Static pressure tap will be located up stream

The solution as per below tools:
