PEAT-GAS-PRODUCING PROCESS.
Specification of Letters Patent.
Patented Dec. 6, 1910.
Application filed February 4, 1909. Serial No. 476,115.
To all whom it may concern:
Be it known that I, JEAN Dnnriiion OLIGNY, resident of 87 St. Augustin street, in the city and district of Montreal, in the Province of Quebec, in the Dominion of Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Peat-Gas-Producing Processes; and I do hereby declare that the following is a full, clear, and exact description of the same.
The invention relates to a peat gas pro ducing process, as described in the present specification and illustrated in the accompanying drawing that forms part of the same.
The invention consists essentially in the various steps hereinafter more particularly set forth and pointed out in the claim.
The object of the invention is to utilize the peat, so readily obtainable, in the most economical manner, that is through the cheap production of a gas having illuminating as well as heat and power producing properties.
The drawing is a view showing merely the outline of the parts to the plant, used in this process.
The first step in the process is destroying the capillary nature of the peat by placing it under crushing rollers 1 or in fact any suitable crushing means and during this step saturating the said peat with petroleum or other hydro-carbonaceous oil 2, then insert ing said peat so pulped and charged with petroleum into a retort 3 heated by the furnace 3 and baking, until the mass becomes thoroughly coked and relieved of all the gas and during this step injecting air from the compressed air reservoir 9 into the said retort, thus warming said air thoroughly and at the same time lading the gas with air, as warm air will readily mix with the rich peat gas, then passing the gas from said retort through a carbureting chamber 4: containing tar preferably obtained as a byproduct from the peat itself, then passing the gas through a suitable pipe and through condensing arrangements 6 and dropping the by-products in passage into suitable receptacles 7 and finally passing the gas into a gasonieter or gasholder 8.
The gas on leaving the retort is, as herel inbefore mentioned, laden with air and in this state reaches the carbureting chamber containing the tar and in this cooled chamber the mixed air and gas is carbureted and much of the tar carried with the gas drops back into the said chamber from above. The overflow of the tar chamber is taken care of by an overflow passage and receptacle 9 and 10.
The condensing of the gas further on in the process will cause the eXusion therefrom of any further excess of tar and also other by-products, as also later on in its flow, the
exusion of alcohol, the gas finally reaching the gas holder or gasometer with its illuminating, heating and explosive properties intact and generally in first class commercial condition.
The tar in the carbureting chamber is, of course, in a liquid state as it is being continually fed from the tar by-product dripping from the gas, ascending after it has passed through the said chamber, the overflow of course flowing through the said overflow passage, which passage has a suitable trap therein for sealing purposes.
What I claim as my invention is:
The herein described peat gas producing process, consisting in first taking the peat in its natural moist state and crushing, and sprinkling it during said crushing with petroleum oil thus destroying the capillary nature of said peat and producing a pulpy petroleum charged substance, then subjecting said substance to intense heat, then injecting air by forced draft to mingle with the gas from said peat during the step of coking JEAN DELPHIOE OLIGNY.
