Abstract
Abstract Disclosed is a method and apparatus for promoting chemical reactions in a hydraulic column, preferably in the form of a well, provided with an outer casing, an inner liner within and spaced from the casing, and a steam line within and spaced from the inner liner. A downwardly flowing column of a material to be treated is introduced between the casing and the liner and is heated at the bottom and caused to undergo chemical changes due to the high pressure and temperature conditions. The reaction zone located generally at the bottom of the well is maintained free of extraneous oxygen, that is, free of oxygen except that which might be inherently entrained in the fluid material. The heated material is forced upwardly between the liner and the steam line solely by the column pressure and may be continuously removed at the top, thus providing a continuous process. If the material being treated is sewage, it may be provided to the column in its raw state, that is, not being concentrated or fortified by refuse or other combustible materials.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A METHOD FOR TREATING A CONTINUOUSLY FLOWING SEWAGE MATERIAL COMPRISING THE STEPS OF, FEEDING THE SEWAGE MATERIAL INTO THE TOP OF A HYDRAULIC INFLUENT COLUMN CONDUCTING SAID MATERIAL FROM THE BOTTOM OF SAID INFLUENT COLUMN INTO THE BOTTOM OF A SEPARATE HYDRAULIC EFFLUENT COLUMN, CONTINUOUSLY SUPPLYING HEAT ENERGY TO THE MATERIAL NEAR THE BOTTOM OF ONE OF SAID COLUMNS AT THE REACTION ZONE TO PROMOTE CHEMICAL REACTIONS AND DECREASE THE SPECIFIC GRAVITY OF THE MATERIAL, LIMITING COMBUSTION OF THE MATERIAL BY RESTRICTING THE PROCESS TO OXYGEN PRESENT IN THE MATERIAL BY RESTRICTING THE PROCESS BOTTOM OF SAID INFLUENT COLUMN CAUSES THE HEATED MATERIAL TO RISE IN SAID EFFLUENT COLUMN, AND REMOVING THE MATERIAL FROM THE TOP OF SAID EFFLUENT COLUMN.
Claim 2
Independent Claim
120 words
A METHOD FOR TREATING A CONTINUOUSLY FLOWING SEWAGE MATERIAL COMPRISING THE STEPS OF, FEEDING THE SEWAGE MATERIAL INTO THE TOP OF A HYDRAULIC INFLUENT COLUMN CONDUCTING SAID MATERIAL FROM THE BOTTOM OF SAID INFLUENT COLUMN INTO THE BOTTOM OF A SEPARATE HYDRAULIC EFFLUENT COLUMN, CONTINUOUSLY SUPPLYING HEAT ENERGY TO THE MATERIAL NEAR THE BOTTOM OF ONE OF SAID COLUMNS AT THE REACTION ZONE TO PROMOTE CHEMICAL REACTIONS AND DECREASE THE SPECIFIC GRAVITY OF THE MATERIAL, LIMITING COMBUSTION OF THE MATERIAL BY RESTRICTING THE PROCESS TO OXYGEN PRESENT IN THE MATERIAL BY RESTRICTING THE PROCESS BOTTOM OF SAID INFLUENT COLUMN CAUSES THE HEATED MATERIAL TO RISE IN SAID EFFLUENT COLUMN, AND REMOVING THE MATERIAL FROM THE TOP OF SAID EFFLUENT COLUMN.
Claim 3
Dependent Claim
18 words
The method of claim 1, in which the rising effluent column transfers heat to the descending influent column.
Claim 4
Independent Claim
145 words
A method for treating an oxygen-deficient sewage material comprising the steps of, continuously feeding the material into the top of a hydraulic influent column; conducting the material from the bottom of said influent column into the bottom of a separate hydraulic effluent column; continuously supplying heat energy to the material near the bottom of one of said columns at the area of greatest temperature and pressure to promote chemical reactions to decrease the specific gravity of the material, and to provide a pressure differential between the material in said influent column and the material In said effluent column, the pressure differential provided by the heat being the sole cause by which the material rises in said effluent column; limiting combustion of the material by restricting the process to oxygen present in the material; and continuously removing the material from the top of said effluent column.
Claim 5
Independent Claim
145 words
A method for treating an oxygen-deficient sewage material comprising the steps of, continuously feeding the material into the top of a hydraulic influent column; conducting the material from the bottom of said influent column into the bottom of a separate hydraulic effluent column; continuously supplying heat energy to the material near the bottom of one of said columns at the area of greatest temperature and pressure to promote chemical reactions to decrease the specific gravity of the material, and to provide a pressure differential between the material in said influent column and the material In said effluent column, the pressure differential provided by the heat being the sole cause by which the material rises in said effluent column; limiting combustion of the material by restricting the process to oxygen present in the material; and continuously removing the material from the top of said effluent column.
Claim 6
Dependent Claim
112 words
In a process of treating raw sewage material including the steps of feeding the sewage material into the top of a hydraulic influent column, transferring said material from the bottom of said influent column to the bottom of a separate hydraulic effluent column, and removing the material from the top of said effluent column, the improvement comprising the additional steps of supplying heat energy to the material near the bottom of one of the columns so that the specific gravity of the sewage material will decrease and the material will rise in the effluent column, and limiting combustion of the material by restricting the process to oxygen present in the sewage material.
Claim 7
Dependent Claim
112 words
In a process of treating raw sewage material including the steps of feeding the sewage material into the top of a hydraulic influent column, transferring said material from the bottom of said influent column to the bottom of a separate hydraulic effluent column, and removing the material from the top of said effluent column, the improvement comprising the additional steps of supplying heat energy to the material near the bottom of one of the columns so that the specific gravity of the sewage material will decrease and the material will rise in the effluent column, and limiting combustion of the material by restricting the process to oxygen present in the sewage material.
Claim 8
Dependent Claim
27 words
A process according to claim 4, wherein said step of heating the material is done while restricting the process to combustible material present in the sewage material.
