Abstract

163,363. Illing, V. C., and Kelly, J. Nov. 18, 1919. Hydrocarbons, distilling; hydrocarbons, cracking; separate heater and evaporator apparatus.-In distilling petroleum, oils, distillates and tars, the oil is forced by a pump through preheating tubes P in the condensers N and through a tube A heated by an electric coil and is admitted through a valve C into an evaporator D heated by a surrounding electric coil or by other means. The liquid is distributed by funnels H onto a series of inclined plates E. The vapours are withdrawn by a pump which maintains a reduced pressure in the evaporator, through a series of condensers N maintained at different temperatures by the pipes P through which the oil-supply flows in series. The residual liquid from the evaporator D passes to a vessel L from which it is forced through a similar heater R and evaporator S in which it is treated with air to yield asphalt, as described in Specification 163,656. Vapours evolved in the evaporator S are withdrawn through a series of condensers X cooled by passage of crude oil through tubes contained within them. Steam may be admitted to the evaporator through a valve M. Temperature-regulators B, K are fitted to the heater A and evaporator D. In a modified apparatus, the heaters and evaporators are heated by gas or oil fuel burners, the residue from the first evaporator is passed through the cooling- coils of the condensers connected to the asphalt chamber, and is passed through an intermediate heater and evaporator before being treated to form asphalt. Cracking of the oils may be obtained by heating them above 400‹ C. Specifications 1706/82, 12181/98, 27615/12, 16713/14, 117,372, 127,700 and 145,894 are referred to.
