Wet gas flow measurement in renewable energy operations ISO/NP TS 23610

Scope

This Technical Report describes the metering challenges and approaches to the measurement of wet gas flows as required by renewable energy applications, e.g.. hydrogen with entrained water flow, gas / liquid carbon dioxide flow, wet biogas flow, and geothermal saturated steam flow.
The energy industry that developed and used wet natural gas flow meters has broadened its interest and activity into renewable energy related wet gas flows, e.g. hydrogen storage, geothermal steam, carbon capture and storage, biogas wet gas flows.
Hydrogen extracted from storage has entrained water, carbon capture flows are often processed close to the phase boundary producing wet gas flow, biogas is often wet, some solar field designs have wet saturated steam flows, and geothermal power plants receive wet saturated steam from the geothermal wells. All applications lie outside of the scope of wet natural gas metering standards documents yet are analogous.
There is dearth of information in the literature on how to approach such wet gas metering. However, some of the wet gas metering technology developed by the hydrocarbon production industry is applicable. This technical report discusses the wet natural gas metering technology applicable to such applications, inclusive of discussing the similarities and differences, and the pros and cons of different methods.
