Abstract

The paper presents a new correlative energy measurement method developed under a joint project of Ruhrgas AG, Germany, and Nederlandse Gasunie N. V., the Netherlands. The paper mainly refers to the results obtained from a previous feasibility study proposing a method using as input parameters dielectric permittivity, speed of sound and CO₂ mole fraction. On the basis of these input parameters, superior calorific value and natural gas composition can be determined. Total uncertainty envisaged for superior calorific value is 0.2 %. Initial laboratory tests confirm that the uncertainty envisaged can be obtained or is even better. The method is to be tested in the field soon.
