REFINING METHOD AND APPARATUS.

Specification of Letters Patent.

Patentedllt. 3, 1916.

Application filed February 19. 1916. Serial No. 79,274.

To all whom it may (20 acorn Be it known that I, An'ruUn NEAL lxnnn,

a citizen, of the United States, residing at Tulsa, in the county ot' Tulsa and State of Oklahoma, have invented certainnew and useful Improvements in Refining Methods and :)paratus, vof which the'following is the specification.

This invention relates to a method and Lubricating oil and burning oiL (30 l. naphtha 70 B. straight run gasolene 7 to 15 8-1-86 l) 25 to 50 Tops 106416 B 35 to 50 Prior methods of treatment and distillation have, in so far as I am aware, always resulted in the complete or substantial loss of the tops.

It is an object ofthe invention to provide a method and apparatus for first distilling and then separating easiug-hezul gasolenc or the. like, and in one operation employing its light lraetious 'or tops to enliven a low-grade product, thus increasing the value of such product and at, the same time save the tops.

It is another object of the invention to provide a method and ap ')aratus where the entire process of treatment of easing-head gasolene or the like may be carried out in a single ope 'ation and 'under very moderate pressure.

Other objects and advantages of theinvention will appear as the description to fol- In the drawings: Figure 1 is a plan View of an. apparatus employed to carry out my new method. Fig. 2 is an elevation thereof.

In the drawings, 1 represents a steam still into which casing-head gasolenej is pumped by suitable means and to which steam under moderate pressure, say from twenty to forty pounds, is supplied through pipe 2, distilling the casinghead gasolene. The distillation products flow up the pipe 3 and through a coil 4.- ,in a vat 5, containing warm Water and summrtedupon a platt'orm (5 so as to be at a considerable elevation above the still 1. From the vat 5 the distillation prod-- ncts flow mto a separation tank 7, from which the heavy condensates are drained back through the pipe 8 to the still, the volatile distillation products passing on through pipe 9 to the cooling vat 10, from which they pass through pipe 11 into tanks or containers 12, 13, H, 15 and 16, as are now to be described.

The tank 13 contains an atomizer 14 in comnul'nication with the pipe 11 and is partially filled with naphtha or low grade product. The first run from the" still (for the most part gas and products of 106, B.

down) is sent past the tanks 12,14 and 1c and into the atomizer 1t, bubbling up into thejank 13 and being almost entirely and completely absorbed therebyfwith the exception of a small amount-of, gas escaping at safety valve 26. This process is carried on until the distillation product reaches 96 Baume, whereupon the tank 13 iscut otl" by means of the stop cock 1?, the product then running into the St-86 tank 12, into which it runs until the kilistillation product reaches 72 B. equipped with safety 27 to relieve excess gas. The product obtained from the 8-t86 Tank 12 is alsois gas machine gasoleue of average gravity 84-86" I). and is salableat a higher price than ordinary gasolene. After the product rea(-.-hes 72 it is cut bymeans ot' the stop cocks 20, 21, 22,23 and 21, into the tanks 1+. 15 and 16, these tanks respectively receiving the distillation 'iroducts down to T0438 and 66, while still further tanks may be supplied as is perfectly obvious to receive lower grades, (3+ and other grades of straight run gasoleuc.

It will be in'nnediately seen'that by the method hereinabove disclosed, the large amount of tops in easing-head gasolene is saved, and at the same time the value of the naphthais increased and the entire process is carried on under moderate pressures and at a single operation.

I claim:

1. A method of treating easing-head gasolene which consists in distilling the, same in a steam still under moderate pressure, in thereafter nuulerately eoolirg the products of distillation, in absorbing the light volatile distillate fractions in naphtha or the like,

according to their nature, whereby all of:

the casing head gusolene' will be treated in a single process and a log grade product simultaneously 1m roved.

.2. A method 0 treatipggas well prod and in grading the remaining fractions fipely divic ed ,form into a.

into separate containers at predetermined 'Baum gravities, substantially as described. "4; A method of treating gas well products which consists in passing light gasolenc through anibderatc pressure still, permitting the distillation product to settle and cool, 'in' running the first run light fractions down to approximately 96 Baum into a low I ade product in finely divided form to be a sorbed by the same in cutting the product fronrapproximately 9,6 to approximatcly :72 into a container and in cutting the heavier distillate into graded tanks substantially as described.

In witness whereof, I hereunto subscribe my m'unegto this specification in the presence of two witnesses.
