Aneka Gas supply propane, a
three-carbon alkenes. Propane is sometimes derived from other petroleum products
during oil or natural gas processing. Propane is not produced for its own sake,
but as a byproduct of two other processes: natural gas processing and petroleum
refining. Unlike natural gas, propane is heavier than air (1.5 times denser). In
its raw state, propane sinks and pools at the floor. Liquid propane will flash
to a vapor at atmospheric pressure and appears white due to moisture condensing
from the air.
