Rare gas recovery and specialty gas systems for exacting requirements
IGS supports enquiries involving the recovery, purification and liquefaction of rare gases and the preparation of high-purity specialty gases. The technical route depends on the feed source, trace concentration, impurity profile, required purity, product state and recovery objective.
High-value outcomes
Small fractions. High-value outcomes. Exacting control.
Rare gases are often present at low concentrations within much larger process streams. Commercial value depends on recovering and purifying the right product without losing sight of feed variability, integration, product quality and the economics of the wider process.
IGS helps frame the requirement clearly enough for a meaningful technical review.
Recovery interfaces
Bring the source process and final product into one brief.
A rare-gas opportunity needs a clear boundary between the source plant, the recovery package and downstream purification or handling. That boundary is especially important when recovering a small fraction from a much larger stream.
Identify the source
State whether the opportunity is linked to air separation, natural gas processing or another gas stream, and provide available trace-component analysis.
Separate recovery from final purity
Define the required intermediate and final products, including impurity limits, analytical method and where product acceptance will take place.
Close the handling boundary
Include transfer, storage and packaging requirements in the enquiry so the recovery equipment can be assessed within the complete system.
Equipment reference imagery from technical literature. Configuration and supply scope are defined for each project.
