ABSTRACT:
A method of determining the minimum level of enrichment required to render a substantially miscible gas miscible in a liquid hydrocarbon by observing the behavior of liquid hydrocarbon droplets as they fall through samples of enriched gas of incrementally increasing levels of enrichment. The lowest level of enrichment at which the droplet is observed to dissipate in the enriched gas is the minimum level of enrichment.
