Definitions
- This invention relates to the manufacture of fuel gas from hydrocarbons and. more particularly refers to a new and. improved process and apparatus for converting normally liquid hydrocarbon oils and condensible hydrocarbon gases referred to in the industry as L. P. gas or liquidpetroleum gas which gases include propane, butane and pentane into a highly combustible homogeneous gas of'a quality adapted to be principally used for heating.
- L. P. gas or liquidpetroleum gas which gases include propane, butane and pentane into a highly combustible homogeneous gas of'a quality adapted to be principally used for heating.
- the oil cracking apparatus should be flexible particularly in its ability to treat less costly fractions of petroleum oils such as low gravity gas oils or heavy residuums and also in its capability of changing the properties of the gas product within reasonable limits and its rate of production without seriously impairing the operation. Since price is a dominant factor controlling the sale of fuel gas over other competitive fuels all elements entering into the cost of the gas such as investment cost, value of charging stock, operating cost, maintenance and yield are of paramount importance to the manufacturer. In view of the high volume of gases consumed, small differentials in price per 1000 cu. ft. of heating gas which may appear insignificant, when multiplied by the total output of the gas in millions of cu. ft. assume substantial proportions in dollars. Furthermore, oil cracking machines should not only be simple and efiicient in operation but also compact in design.
- the quality of a heating gas is, of course, governed by the consumers" requirements.
- the greatest number of customers of gas burn gas in atmospheric gas burners fixed in the sense of having orifices of a definite size and air shutters open to a predetermined extent which cannot conveniently be changed thereby imposing on the gas producer the necessity for maintaining a uniform quality of gas.
- Other important considerations in the efiicient operation of atmospheric burners are the properties'of the gas, particularly the calorific value and density of the gas.
- a gas should have a B. t. u. per cu. ft.
- anoil gas having these characteristics being hereinafter designated as high B. t. u. low gravity gas.
- the density of a gas is influenced to alar egdegree by its content of hydrogen and illuminants, i. e. hydrocarbons of higher molecular weight. Gases containing too large a volume of hydrogen tend to flashback and gases haVingQtoo large a percentage of illuminant's give anl'elongated flame. To my knowledge none of the prior art oil cracking de- -vices'has succeeded.fin coinmercially producing high B. t. u. low gravity gas.
- a further object of the invention is to provide an oil gas apparatus simple in construction, compact in design, and durable, certain and efficient in operation.
- a still further object of this invention is to provide an improved process and apparatus for decomposing hydrocarbon oils into gas which is economical, elastic and flexible in operation.
- Apparatus for carrying .out the conversion .of oil into gas in accordance with :the. present invention involves a novel combination and arrangement .of elements including two vertical refractory lined duplicate vessels connected at their tops by asgasrchannel, each vessel constructed to provide an empty chamber above another chamber at least partially filled with checkerbrick or refractory material with voids therebetween to permit the passage of gas therethrough and divided therefrom by a refractory circular orifice, two vertical refractory lined riser pipes'extending upwardly :to a height above the vessels with each riser pipe connected to the base of a refractory ifilled chamber, a stack valve fitted to the top of ..each riser pipe, conduits leading from .the top .of each ,riser pipe :connected to a three-way valve for reversal of flow in the apparatus and for the release of make gas, an inlet for the introduction :of primary air into each riser pipe, a steam conduit leading into each riser pipe, .a gas
- plete cycle of operation comprises, (a) a blast lhe operation .ofemy process involves passing 7 air upwardly through a first zone at least partially filled with heated refractory material with voids therebetween'to permit the passage,
- This I accomplish by first heating the empty chamber to a peak cracking temperature of the system and then injecting hydrocarbon oil into the heated empty chamber countercurrent to an upward flow of a mixture of steam and hydrocarbon carrier gas introduced into the bottom of the empty chamber at a velocity high enough to prevent the oil and carbonaceous materials from flowing down through the chamber.
- the combination of upwardly flowing steam and hydrocarbon gas and peak temperature in the empty chamber causes vaporization and cracking of the liquid oil with concomitant production of carbon and carbonaceous material which deposit on the walls of the empty chamber leaving effluent vapors and gas substantially free from solid carbonaceous material and liquid oil for'further conversion, i. e. fixing, in a separate zone.
- Confining the bulk of the carbonaceous material to the walls of an empty chamber is beneficial in that the flow of materials through the apparatus is not materially impeded, thus maintaining high throughput as well as reducing shut-downs for cleaning. Furthermore, avoidance of material deposition of carbonaceous material on the checkerbrick eliminates rapid deterioration of the brickwork which normally requires frequent replacement, due, it is believed, to thermal shock resulting from direct impingement of the carbon on the checkerbrick and the burning of the carbon from g the checkerbrick causing localized hot spots.
- hydrocarbon carrier gas to the steam during the make period has manifold advantages. It supplements the steam as a propelling agent for carryingthe oil vapors through the apparatus. It aids "inqpreventing oilv and carbonaceous material from dropping 'down through the bottom of the empty chamber. It
- portions of the oil are overcracked with the deposition of excess carbon and other portions of the oil are undercracked with incomplete uti lization of the oil.
- more favorable temperature conditions in the cracking zone may be attained by blasting upwardly through an empty reaction zone to a peak gas making temperature and then passing combustion gases downwardly through another empty.
- the downward flow of gases through the empty reaction zone and checkerbrick section of the fix ing zone gives a relatively even downward temperature gradient following the path of combustion gases and a more uniform heat distribution throughout the checkerbrick section.
- the introduction of a hydrocarbon carrier gas during the make period has the cumulative effect of better distribution of the oil thereby also mini- 5O mizing overcracking and undercracking.
- the accompanying drawing is a diagrammatic fiow sheet illustrating the apparatus and process of the present invention.
- terials 3 which refractoryJining absorbs heat and also protects the metal shell 2 which sur rounds it from the direct impact of hot gases.
- insulation may be interposcdbetween shell 2 and refractory lin ing Vessel I is divided'into two sectiona'an empty upper reaction chamber i'and a lower preheating or fixing chamber 5 filled with a refractory material 6 wherein will be retained and stored up surplus heat and which will give up heat.
- Dividing reaction chamber i and fixing chamber 5 is a circular orifice lwhich has the function of effecting thorough' mixing of the gases and also imparting a high velocity to the gas entering the bottom of chambers
- a refractory lined conduit 8 connects the bottom of vessel 1 with the bottom of refractory lined riser pipe 8 which extends upwardly to a height, suitable to carry the blast gases above other equipment and to provide draught when the set is. shut down.
- a stack valve I l is fitted to the top of riser pipe 9 and disposed above it is stack 12. Make gas discharges from the top of riser pipe 9 through line i3 connected to a conventional three-way reversing valve l4. Primary air introduced for example by a blower, not shown in the drawing, enters,
- Steam may be introduced into riser pipe 9 through line I8 and valve 19.
- Hydrocarbon carrier gas from an external source joins the flow of steam entering through line 65, valve -29 and entrance 2!, preferably disposed at the. bottom of riser pipe 9 V
- recycle make gas is returned as thecarrier agent to the bottom of preheating chamber-5 through line 56,
- Make oil is fed throughlines 2 2, 23, valve 24 and sprayed downwardly'by means of nozzle 25, of conventional design; counter-current to the upward flow of gases in reaction chamber 5.
- Heat oil passes through line 26, 21, valve 23 into reaction chamber 4 through nozzle 29.
- a'carrier gas- may be dispcnsed with entirely and'steam in the absence of event no make gas would be recycled or make gas returned only during a part of the make time.
- No. 2 set and No. 1 set are substantially duplicates, the corresponding elements of set No. 2 bearing the following numerals: Vessel 35, metal shell 36, refractory lining 3?, reaction chamber 38, fixing chamber 3Q,.checkerbrick 3i, orifice 42, riser pipe 43, connecting conduit 4 stack valve G5, stack 46, steam inlet and valve ii? and 38, respectively, hydrocarbon carrier gas inlet and valve 49 and 50, hydrocarbon carrier gas con duit from an external source 653, recycle line, valve, exhauster I I, 12 and i3, respectively, primary air inlet and valve 52 and 55, respectively, secondary air inlet and valve 54 and 55, respectively, make oil line, valve and nozzle 5? and 53, respectively, heat oil line, valve and nozzle v59, 6
- a complete cycle of operation in accordance with the present invention may be divided into four primary periods-a blast period,; a make gas period, a reverse blast period and a reverse make period with purges between the primary periods.
- stack valve H is closed, stack valve 451s, open and reversin valve it is set against No. 1 set.
- Primary air is admitted through lines l5, l6,
- valve ll, line I3 into the top of riser pipe 9 passcarrier gas employed as the propelling medium
- the quantity of make gas produced may be so small as to make it difficult to recycle make gas at the initialstag'e of the make period and therefore the return of make gas may desirably'be dew layed for, by way of illustration, the first 30. sec-- onds.
- an operator may wish to limit the degradation of make gas normally accomplished by recycling in which.
- conduit 8 thereby partially preheating the air by its contact with the refractory lining before entering the bottom of chamber 5.
- the partially preheated air passes upwardly through checkerbrick 6 thereby becoming heated to a higher temperature by refractory 8 and also burns any slightamount of carbon whichmay be deposited thereon.
- the highly preheated air flows through orifice i into empty chambers wherein secondary air enters by way of lines 34, 32 and valve 33.
- Heat oil pumped through lines 25, 2'5 and valve 28 discharges through, nozzle into the atmosphere of air whereupon the oil ignites, generating heat which is imparted to the walls of chamber 4. The quantity of.
- air supplied should desirably be greater than that required for complete combustion of the heat oil, thereby pro viding an excess of air for burning any carbonaceous depositsfrom'the walls of chamber 4 made during a previousmake period.
- Com bustion gases together with highly heated. secondary air pass'through crossover 35 downwardly throughempty chamber 38 heating its Walls and burning carbon thereon.
- carbonaceous deposits unconverted into blue gas during the make period are utilized for heating the reaction chambers, efiecting a saving in heat oil consumed and in some instances eliminating the need for heat oil.v
- the resultant combustion gases pass through orifice.
- Alinear velocity of the mixture of steam and gas of about 50' feet per second will for most conditions of operation be found satisfactory.
- vaporization of the oil occurs almost instantaneously in the empty space of reaction chamber 4 and substantially all the carbon liberated as a result of the vaporization and cracking of the oil therein will adhere to the internal surface of empty chamher 4.
- this carbon Upon reaching incandescence this carbon will react with the steam to form blue gas. Carbon remaining on the walls ofchamber 4 will be converted to heat on a subsequent blast run.
- the mixture of gases discharges from the top of chamber 4, through crossover 34 into empty chamber 38, also at a high temperature due to the previous blasting operation; wherein decomposition of the oil vapor molecules continues with further deposition of carbon on the walls of empty chamber 38 (minor in amountin com parison with the carbon deposited in chamber 4) and further production of bluefgas during the downward passage of the gas and steam'in vessel 35.
- the gases are fixed by their downward passage through checkerbrick 4
- may be accomplished in various manners, as for example by the use of a steam injector to withdraw a portion of the make gas from' the bottomof vessel 35 was an alternative to install a gas exhauster to withdraw make gas from the foul main and introducethe make gas with steam at the top of riserpipe [8. In some instances the'return of a portion of make gas from crossover 34 to riser pipe 9; or' the bottom of fixing chamber-1 may be fou'nd advantageous. It is not essential to admix the hydrocarbon carrier gas with the steam prior to passage through refractories 6 and therefore the carrier gas maybe commingled with the steam near the bottom. entrance of reaction chamber 4.
- a normally gaseous hydrocarbon such as methane; ethane, propane or. mixtures thereof may be employed as the hydrocarbon carrier gas from an external source.
- the combination of hydrocarbon carrier gas and my method of blasting and making have the cumulative efiect of reducing the'amount of carbon deposited which permits the use of smaller quantities of steam which in turn results 'in a higher calorific gassince the greater theamount of steam the lower the B.'t. u. content of the gas.
- the make gases leaving'the bottom of vessel 35 pass through conduit -44 up through riser pipe 43 and thence discharge through conduit 5
- the time for individual blast and make periods will vary dependent upon the nature of the charging oil, operating conditions, and quality of gas desired. Blast and make DBIiOdSjOf from 3-19 minutes duration will ordinarily "be found satisfactory. High superatmospheric Orsubatmospheric pressures are unnecessary since the operation of my process may becarriecl out efficiently at substantially atmospheric pressure.
- the system In order to avoid an explosion hazard, the systemshould be purged of combustible gas prior to the introduction of air in the succeeding blast period. Purging may be accomplished by passing steam 1n through line 41 and out through the top ofriserpipell. a it In the practice of my process .a wide variety of charging stocks ranging from LP. gas to heavy liquid hydrocarbon oils may betreated.
- a particular advantage of the present invention resides in the provision of an apparatus and process for the conversiontif low grade. hydrocarbon oils such as heavy cracked residuums having a Conradson carbon number in excess of 10 into high gravity low B. t. In.
- a process for theproduction'of combustible gases which comprises; (a) a blast period wherein air passes downwardly througha previously heated riser pipe thereby effecting partial heat; ing of the air, upwardlythrough the'interstices of heated refractories contained in a first zone thereby further heating the air, passing the preheated air into asecond empty zone wherein secondary air and heat oil are introduced, which latter burns to impart heat to the'walls' of the empty zone, passing the combustion gases resulting from the reaction of the heat oil and air together with excess air downwardly through a third empty zone thereby transferring heat from the combustion gases to its walls and burning any carbonaceous deposits thereon by means.
