OSTI ID:6077694

In this process for treating liquefied natural gas, the gas is separated into methane fraction, which goes directly into the gas distribution system, and ethane and heavier fractions over a demethanizer. The methane is vaporized and the cold potential available at the requisite temperature level is recovered in the ethylene plant. The ethane is then fractionated from the propane and sent to an ethylene plant. The ethane undergoes pyrolytic treatment and the resulting ethylene can be used, for example, for synthesis. Heavier fractions from the ethylene plant are used for fuel. Methane and hydrogen from the ethylene plant are blended with the propane to give a gas having a heating value close to that of methane.
