Description

Adding composite additive and improve welding torch gas hydrocarbon of quality and preparation method thereof
The present invention relates to hydro carbons, this hydrocarbon comprises and is used to the welding torch gas that cuts and/or weld, automotive fuel and heat gas and oil, and it is improved by adding composite additive or conditioning agent.
A main purpose of the present invention provides as the performance that is had and is better than acetylene, especially for the torch gas of cutting ferrous metal and also can be used for the hydro carbons of the above-mentioned improvement quality of electric welding.This purpose also comprises the hydro carbons that above-mentioned improvement quality is provided, and the performance that it had is better than only improving by the adding methyl ethyl ketone performance of the hydro carbons of quality.
A special purpose provides has the torch gas that high flame gentleness is forced heat energy power.
A further purpose provides torch gas, its storage and convenient transportation and economy.
Another purpose provides and contains the torch gas that all is easy to the base-material gas that obtains in the whole world almost, and this base-material gas can be provided more economically and be easy to doping and improve quality to strengthen its performance.
Also have a purpose to provide the torch gas that to cut ferrous metal faster and more neatly.
Another purpose provides a kind of gas, and it can be used to welding torch in quite dark cutting under water.
The another one purpose provides a kind of gas, and it can be used for welding torch cutting more economically, because it can be with the oxygen that contains a high proportion of impurity gas that can not use with acetylene chemical combination effectively.
Above-mentioned purpose can be added with the trimethyl carbinol (TBA) or methyl tertiary butyl ether (MTBE) by use and improve the quality of having improved the liquefied petroleum gas (LPG) (LPG) of quality by butanone (MEK) and finish.
Further purpose of the present invention provides the improvement quality hydro carbons of non-torch gas purposes, for example is used for heating, as being the industrial furnace of casting deposite metal and the heat gas or the oil of blast furnace.
This further purpose can be by using MEK and TBA or MTBE to improve liquefied petroleum gas (LPG), Sweet natural gas or finishing as diesel oil or fuel oil liquid hydrocarbon.
Also having the another one purpose is to improve the liquid hydrocarbon, particularly gasoline that is used as automotive fuel with doping, to prevent detonation and to guarantee that incendiary is even.
Further purpose can to have added TBA or MTBE be that the MEK of additive finishes by adding in gasoline for this.
Liquefied petroleum gas (LPG) (LPG) is because its high butane and propane content become the preferred base-material gas of the torch gas of improvement quality of the present invention.The normal butane of butane and Trimethylmethane isomer all are present among the LPG usually, but because industrial demand to the butane derivative, as be used for fuel, and considerable butane may shift out from LPG, and LPG is made up of propane basically owing to this reason.But wish in LPG, to have the butane of suitable proportion, as from 5% to 40%.In addition, base-material gas also can be the independent propane or the arbitrary mixture or the propylene of butane or these two kinds of gases.
(be also referred to as uncle-butanols (TBA), its structural formula is (CH in order to be added with tertiary butyl alcohol to be used to improve the additive of base-material gas of quality or conditioning agent 3) 3COH) or methyl tertiary butyl ether (be also referred to as methyl-tert-butyl ether (MTBE), its structural formula is (CH 3) 3COCH 3) methyl ethyl ketone (MEK) (be also referred to as 2-butanone, structural formula CH 3COCH 2CH 3).MEK is 70.6 ℃ of boiling points, and 20 ℃ of proportion is 0.805 liquid.TBA is that fusing point is 25.6 ℃ a waxy solid under the room temperature, and 26 ℃ of proportions are 0.779.MTBE is 55 ℃ of boiling points under the room temperature, freezing point-110 ℃, and proportion is 0.74 colourless liquid.
Must store LPG and be in liquid state adding to depress to keep it, but the storage tank of more high voltage bearing LPG and handling equipment be commercially practical with normally used.
What be not modified quality can not be used for welding torch cutting and electric welding very effectively with oxygen blended LPG, and it is far away not as good as effective with the acetylene gas of purified oxygen mix basically; Usually be that additive enriches base-material LPG with the MEK that is added with TBA or MTBE, the flame temperature obviously improves and heating efficiency is improved greatly.
Additive usage quantity foundation is decided the desired improved degree of base-material hydrocarbon, and this usage quantity should be in the 0.5%-20% scope of base-material hydrocarbon weight.In the purposes of welding torch gas that improves quality such as LPG, consumption can mostly be 3% TBA of LPG weight or MTBE and mix, as the MEK of 3%-10% base-material gas weight is added with TBA or the MTBE of base-material gas weight 1%-3% with 15% MEK for LPG weight.Usually can obtain fully favourable result by using as TBA or the MTBE that the MEK blended of LPG weight 10% accounts for alkyl material 2% with consumption.
This LPG and additive blended method is very simple.MEK is a liquid under the normal temperature.Be to mix TBA and MEK, can put into as temperature by the container that will fill TBA is that 40 ℃-45 ℃ warm water makes its fusing, then with additive liquid with TBA liquid is simply mixed before hydrocarbon mixes with MEK liquid.With additive liquid with make MTBE liquid and MEK liquid mixing before hydrocarbon mixes.Additive is liquid and is transported to the hold-up vessel that is used for storing or transporting this LPG under the normal temperature.Add in standard 55 GPB this additive very feasible.
Can be with this additive and a kind of catalyzer, preferably Powdered, particulate state or flaky activated carbon add jointly.This activated carbon is unbodied, preferably makes from coal or petroleum coke.The catalyzer that may be utilized in addition is the platinum on the suitable carrier, cupric oxide and granular silver.
The usage quantity of activated carbon there is no strict demand, but depress mixing of the alkyl material gas that is added in this container with adding with short this additive its bottom that should be placed on storage vessel.The catalyst consumption of weight of additive 1%-5% will be gratifying.The mixture of the base-material gas of gained and additive or adjustment agent will be an azeotropic, and therefore it will be a homogeneous when the reinforcement torch gas is released into welding torch from storage vessel.
For effective cutting flame is provided, must in acetylene welding torch, supply with purified basically oxygen, as be at least 99% oxygen (by volume), will be than the oxygen of low-purity, be about 95% as purity, hotchpotch is other gaseous fraction of nitrogen, carbonic acid gas and air, and mixing with the base-material gas of improvement quality of the present invention to provide gratifying cutting temperature.Improve the base-material LPG of quality by using with MEK and MTBE, even when the oxygen of use 90% purity, the flame temperature of base-material LPG also can rise to about 5,800 °F (3,200 ℃)-6000 °F (3320 ℃) from about 5,000 °F (2760 ℃) according to of the present invention.Can pass through to about 4 air pressurized, 000psi, and be chilled to-360 °F (280 ℃) and make liquefaction of air, the liquefied air temperature is raise gradually, to the nitrogen component in the vessel port release liquefied air, it leaves liquid oxygen in-320 (196 ℃) vaporization and makes this impure oxygen economically simultaneously.
In other method of the impure oxygen of preparation, available zeolite is removed the oxygen that airborne nitrogen obtains 90-95% purity.
The base-material lancing ferrous metal that uses improvement quality of the present invention is to obtain a totally otch accurately than the superior part with acetylene.Oxy-acetylene cutting produces the hard slag be attached to securely on the workpiece, and it increases required heat supply, and usually subsequently must be with its excision from the workpiece.Use the torch gas of improvement quality of the present invention to produce the low frangible slag of hardness, it comes off and drops on outside the otch from workpiece at cutting process, stays narrower clean otch along the opposite edges of otch to primary metal.
The special benefits that the present invention improves the torch gas of quality is dark to be used for the flame cutting under water at 300 feet.The use of oxy-acetylene welding torch be limited in 20 feet under water dark because in depths more be make gas be conducted to this gas of cutting welding torch under the pressure that must bear acetylene will blast.Thereby, using MEK can be to use the carbon orphan for the unique selection that adopts for before the additive of hydrocarbon gas, surpassing 20 feet cutting under water in the degree of depth, its effect is slowly and dangerous when using.
When the independent MEK of use helps accelerating metal cutting during as the additive of LPG; The MEK that use is added with TBA makes cutting speed in feet per minute further speed 5%-10%, mixes and uses MEK and MTBE, and cutting speed in feet per minute than uses MEK to speed 20%-25% as additive separately; Than using the MEK that is added with TBA to speed about 15%.
The present invention also can be used to high temperature hydrocarbon heat supply gas except being applied to improve the torch gas, as LPG or Sweet natural gas, and high temperature hydrocarbon heat supply liquid, as boiler oil, stove oil or be used to as smelting or other melting of metal that for example is used to cast or other oil that is used for these commercial runs of vapor generation.For these purposes MEK and TBA or MTBE additive capacity scope can be the 2%-10% of hydro carbons weight.If the amount of additive surpasses 5%, catalyzer such as powdered gac will be used to promote the mixing of additive and hydro carbons.
If additive is mixed with gas, use hydrocarbon gas such as LPG to carry out low temperature welding, brazing or light metal cutting are more effective.At the preferred additive that lacks than with regard to being used to cut or weld the torch gas of heavy metal that uses in this purposes.For low temperature welding, the cutting of brazing or light metal, the consumption of the additive in hydrocarbon gas 2%-5% (weight) scope is enough, and this consumption can fully directly mix with hydrocarbon gas not using under the catalyzer condition.
The another kind of purposes of MEK and TBA or MTBE additive is for being used to improve automotive fuel, as motor vehicle gasoline, and aviation spirit or diesel oil.The function of additive is knock-compound and the quickening that improves fuel and accelerates rate of combustion in such purposes, and it has increased the performance of the production power of fuel subsequently.
For automotive fuel, the weight ratio of 20% TBA or MTBE and MEK is preferred, and therefore the TBA or the MTBE of its material weight of 1% hydro carbons can mix with the MEK of 5% hydro carbons base-material weight.The TBA of 0.5% automotive fuel weight or MTBE just mix with the MEK of 2.5% or 3% automotive fuel weight and can improve the automotive fuel performance effectively in a lot of occasions.
Although should point out emphatically do not have TBA or MTBE to exist the time MEK for to effective additive of hydro carbons, its effect is desirable especially.
