Ionic Liquid and Hydrogen Compatibility Testing, Malaysia


We are in search of a laboratory equipped to perform compatibility tests between ionic liquids and hydrogen. Our requirement is detailed below:

a. Objective:

  • To evaluate the solubility of hydrogen in ionic liquid under various pressures and temperatures.
  • To assess the equilibrium content of ionic liquid components in the hydrogen gas phase under different pressures and temperatures.

b. Equipment and Materials:

  • A steel bottle of approximately 200ml or suitable volume, capable of handling hydrogen gas at 900 barg.
  • Hydrogen supply with 99.99% purity at 900 barg.
  • Ionic Liquid: 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [EMIM][Tf2N], with 99.9% purity.

Note: Hydrogen at 900barg is to be sourced by the laboratory and ionic liquid [EMIM][Tf2N] will be provided by NGLTech.

c. Test Procedure:

  • Fill the container with [EMIM][Tf2N] to 50% of its volume.
  • Pressurize the container with hydrogen gas to the specified pressure (refer to Note 1).
  • Adjust the container’s temperature as per Note 1 (either heating or cooling as applicable).
  • Once the target temperature is achieved, agitate the vessel to ensure thorough mixing.
  • Collect samples of both the gas and the liquid for analysis.

The analysis should determine the H2 content in the liquid and the [EMIM][Tf2N] content in the gas phase.

Note 1:

  • Test at 350 barg pressure and 80°C temperature.
  • Test at 900 barg pressure and 15°C temperature.
