Abstract

The present disclosure describes a process for delivering a blend of two or more compressed gas streams (e.g. H2 and natural gas) to a receiving vessel (e.g. a fuel tank on-board a transportation vehicle.

Blends of H2 and natural gas are interesting as a fuel for internal combustion vehicles as described in EP2527713A1. In EP2527713A1, a process to deliver a blend of two or more compressed gas streams to a receiving vessel at a preset pressure ramp rate is disclosed. The two or more compressed gas streams are delivered under pressure regulation control in response to cumulative mass ratio when at least two of the streams have different compositions.

EP2667276A1 and EP266727A1 disclose methods for providing gas mixtures where the average molecular weight of the mixture is measured using a high-frequency planar piezoelectric crystal oscillator in contact with the gas mixture.

The present disclosure proposes to combine the teachings of EP2667276A1 and EP266727A1 for forming a blended gas mixture with EP2527713A1, with and without the use of pressure ramp rate dispensing.
