Velocity profile survey in a 16-in. custody-transfer orifice meter for natural gas
- Chevron Oil Field Research Co. (US)
This paper describes a research project conducted at Chevron U.S.A. Inc.'s Venice, LA, facility to ascertain that the flow condition inside a nominal 16-in. (406-mm) custody-transfer orifice meter was in compliance with American Gas Assn. (AGA) requirements. The survey was conducted at four flow rates ranging from 160 to 200 MMscf/D (4.53 {times} 10{sup 6} to 5.66 {times} 10{sup 6} std m{sup 3}/d) of processed natural gas at 880 psia (6.1 MPa). Experimental data were collected by a portable data-acquisition system driven by a lap-top microcomputer. The measured profiles indicated that the flow was nearly fully developed at the orifice plate location, and no significant swirling motion was detected. This test successfully demonstrated the techniques and equipment developed for determining actual flow distributions inside orifice meters in the field under normal operating conditions. This technology can be used to detect detrimental flow profiles and to verify compliance with AGA requirements on flow conditions in custody-transfer orifice meters.
