Abstract

An aim of the paper is to show recent data obtained from a new experimental set-up build for the production of the CO₂ gas hydrates. The purpose of the experimental set-up is to analyse the practical aspects of the transformation gaseous CO₂ to the hydrates. The deserving effort to decrease impacts of the global warming is containing the more questionable attempt to capture the CO₂ produced within the electricity production and to avoid a releasing to the atmosphere. The storage in the form of the gas hydrates present an alternative way to more known technologies involved in the projects of CCS (Carbon Capture and Storage). The production of the gas hydrate is observed in the set-up with simultaneously acquired data of state condition close to the phase boundary. The presented work has two goals, first is the estimation of the transformation efficiency of the CO₂ to the hydrates in compare with the theory and second goal is obtaining of the data for new CO₂ hydrates production set-up with liquid circulation and possibility to separate pure hydrate. The experimental analysis of the gas hydrates production process can help to estimate the practical aspects of the hydrates production for a possibility of CO₂ storage in this form.
