2 Contents Part I (Oswin Kerkhof, VSL) LNG Calibration Facility (flow and composition) Background Research goals Functional & Metrological Design Requirements Part II (Marina Safonova, IMS Group) Engineering and Fabrication capabilities Process Description

3 Building traceability for LNG flow metering A three step approach 5-25 m 3 /h kg/min 5 200/400 m 3 /h /3200 kg/min Primary Standard Completed, EMRP project Mid-scale standard Sufficient for Small Scale LNG Project in progress m 3 /h Full scale facilities

4 Primary LNG mass flow standard operated and validated in 2013 at Gasunie Peakshaver

5 Next Step - LNG Calibration Facility Medium sized Flow & Composition

6 Location Rotterdam Maasvlakte, the Netherlands

7 Research Goals

8 FLOW MEASUREMENTS 1. Validating the uncertainty of flow standard Mass flow kg/min => Target uncertainty 0,15%* Volume flow m 3 /h => Target uncertainty 0,20%* * Requires further reducing measurement uncertainty of primary standard down to 0,10%

9 FLOW MEASUREMENTS 2. Investigate performance of at least two types of mass flow and volume flow standards Readings as a function of flow, pressure, temperature Extrapolation functions (to what respect is a water calibration representative for LNG use of a flow meter?) Installation effects (different flow profiles, near boiling conditions, )

10 COMPOSITION MEASUREMENTS Validating the uncertainty of composition standard Cross validation with reference liquefier(s) Uncertainty target: 0,2% on calorific value

11 Design Requirements FUNCTIONAL DESIGN REQUIREMENTS METROLOGICAL DESIGN REQUIREMENTS DESIGN STANDARDS

12 FLOW STANDARD General Traceable to primary standard No boil-off, venting of methane to air minimized Control parameters Flow Rate m 3 /h ( kg/min) Expandable to 400 m 3 /h Line pressure 1 10 barg(g) Temperature -123 to -175 C (1 to 20 C below boiling point) Composition Measurable (Mustang system), not controllable

13 FLOW STANDARD Production performance Capacity 1 Meter under Test (MuT) per day Schedule of MuT 1 6 (expandable to 8 ) US/DS piping 40D upstream, 8D downstream Calibration of two meters in series possible Types of MuT Coriolis, USM, Turbine, dp-type, Vortex and other

14 FLOW STANDARD Metrological design rules LNG velocities are low to avoid flashing / bubbles. No double bends out of plane (swirl!), no straighteners (delta-p!) Temperature measurement at the position of flow meters better than 0,1 C Smallest possible interconnected volumes to avoid in- and expiratory effects during calibration time window

15 FLOW STANDARD Same magnitude as gas at atmospheric conditions!

16 COMPOSITION STANDARD Special design sampler (subcooled conditions) Vaporization at conditions above critical pressure Gas Chromatograph Sampling flow rate at 7,5 ml/min (LNG) / 5 l/min (gas) Connectable to small volume reference LNG (liquefier system NPL and/or Effectech) Connectable to LNG calibration loop
