Trials Of An Online Chromatograph
Enterprise Products Operating, L.P. in San Antonio has conducted trials of the new ABB NGC8106 online gas chromatograph, a lower-cost model designed for analyzing lower natural gas flowrates than ABB’s NGC8206 model. Both units accurately determine the energy content of the gas, which constitutes its sales value in custody transfer transactions.
According to John Lambdin, Analytical Supervisor for Enterprise Products, his company can justify the online NGC8206 model for residue gas flows higher than 10 SCFD, but relies on composite samplers for lower flow rates. The company measures and totalizes gas flowrates with a two-stage orifice flowmeter.
