CO2MIX - VLE (NO2.3)

SINTEF ER FACILITY FOR ACCURATE PHASE EQUILIBRIUM MEASUREMENTS OF CO2-RICH MIXTURES
Test cell of CO2Mix phase equilibrium facility
Setup to prepare highly accurate calibration mixtures

Installation 1: Phase equilibrium setup

The CO2Mix phase equilibrium facility is specifically designed for highly accurate phase equilibrium measurements. An analytical technique is used, where the composition of all fluid phases present in the cell at equilibrium is measured. The facility is primarily designed for vapor-liquid equilibrium (VLE) using the static analytic method, but it has also been used to measure phase equilibria with solids and can to some degree be used for synthetic measurements as well. The pressure and temperature range of the setup are from -60 to 150°C and from 3 to 200 bar, respectively. Material selections and ventilation are adapted to the most relevant impurities in CCS, which could include toxic, moderately corrosive as well as explosive impurities. The fluid phases are sampled and injected directly into a gas chromatograph (GC) for chemical analysis. The test cell has several injection valves connected to precise syringe pumps, such that the total composition can be varied during the experimental series, e.g. to adjust the liquid level during measurements on a binary system to avoid having to refill the cell. The test cell consists of a sapphire tube between two titanium flanges, and temperature control is provided by thermostatic baths. Visual access is possible to the cell contents during experiments using a borescope. Temperature, pressure, and composition measurements are calibrated using traceable standards.


Installation 2: Setup for accurate gravimetric preparation of CO2-rich mixtures

Adjacent to the phase equilibrium setup there is a setup for gravimetric preparation of gas mixtures. It is used to prepare mixtures for calibration of the phase equilibrium setup, but could also be used independently to prepare gases for other types of measurements. A heated gas cylinder roller is also available to ensure uniform composition. Mixtures are prepared in 10 l gas cylinders.

State of the Art, uniqueness & specific advantages

Installations 1 and 2 are both extremely accurate. The former has delivered phase equilibrium measurements with unsurpassed accuracy, while the latter has an accuracy down to below 10 ppm, basically limited by adsorption in the gas cylinders and purity of the source gases

Scientific Environment

Highly accurate phase equilibrium measurements and preparation of calibration gas mixtures involving CO2 and impurities typically found in CCS. For each new system to be studied, composition measurements used in the VLE setup should be calibrated with a set of calibration gas mixtures. The facility is located in the thermal laboratories of NTNU/SINTEF with its available infrastructures and services and directly adjacent to the offices of leading scientists in the field of SINTEF and NTNU.

Operational or other constraints

Specific risks:
Risk is dependent on mixtures and test conditions, but it is minimized by appropriate measures according to SINTEF's HSE system. For particularly demanding measurements, developing appropriate procedures and / or installation of physical safety installation may increase the preparation time and/or costs of the experiments.
Legal issues
Access to the labs of SINTEF Energy Research is dependent on compliance to all relevant procedures and policies of the institute relating to HSE and protection of the intellectual property. Independent use of facilities will be dependent on individual approval as an operator by the SINTEF Energy Research following training.
