Abstract: The present invention provides for a method and apparatus for controlling and raising the temperature of a fitting used to transfer liquefied gas to a storage vessel. A hollow metal tube containing heated inert gas contacts the fitting such that heat is transferred to the fitting. By raising the temperature of the fitting, problems such as leakage due to freezing the o-ring seal can be reduced. The method utilizes a vortex tube as the heat source to avoid problems with sparking when an incendiary gas such as hydrogen is being transferred to the storage vessel.

Abstract: A process for the high-yield recovery of ethylene and heavier hydrocarbons from the gas produced by pyrolysis of hydrocarbons in which the liquid products resulting from the fractionated condensation of a cracking gas for the recovery of almost all the ethylene, are supplied to a distillation column, called a de-ethanizer, at different intermediate levels. At the top of the de-ethanizer the vapor of the column distillate is treated directly in an acetylene hydrogenation reactor, the effluent containing virtually no acetylene being separated by a distillation column called a de-methanizer, into an ethylene- and ethane-enriched tail product, while the head product is recycled by compression or treated for subsequent recovery of ethylene.
