Definitions

• the invention relates to a process for the utilization of organic waste materials and hydrogen from water electrolisis to produce a mixture of gases.
• These mixtures composed mainly of hydrogen (H2) and carbon monoxide (CO), have controlled compositions and calorific powers, owing to the different mixtures produced.
• the primary object of the present invention is to provide an improvement in the process for obtaining a controlled composition and calorific value gas, to be used depending on he cpmposition, in heating (domestic and industrial) or for propolling motors (explosion motor or reaction motor) or in reduction process (mineral reduction process, synthesis gas process, etc.) Disclosure of the invention
• the present invention benefits by two distinct technologies -water electrolisis and pyrolisis of materials, which are rich in carbon, hydrogen and have some of oxygen.
• Ammonia producing units have been in operation for more than 50 years. In Assuwan, Egypt, one of the biggest ammonia producing units has been constructed, and has been operating since before the petroleum crisis. It produces ammonia for fertilizers based on urea. Such fertilizers have been used for the recuperation of the areas not flooded by the Nile River, since the regulation of the Assuwan dam.
• table I are set forth some fuels, the calorific values of the gasificated fuels and their mixtures with air, necessary for combustion.
• the conventional process for the utilization of waste organic material - direct combustion and biodigestion - present respectively a find product, with a low calorific value and low convertion yield.
• the gas produced by pyrolisis of organic residues has a good yield and calorific value, near to that obtained by the natural gas combustion, for example, which is nowadays one of the biggest energy resources, although has a limited lifetime.
• An electric energy generators (1) that can be a hydroelectric station (1A) or a conventional substation (1B) or an ordinary lowering transformer (1C), produces energy for the electrolisis unit (2);
• the electrolisis unit receives treated water from the water-traiting unit (2.1) and is composed of different equipment and systems, including a lung storage tank of hydrogen and oxygen;
• the pyrolisis unit is composed of an area for the preparation of a wate organics materials: (3.1) and a furnace (3.2).
• the gases produced in the pyrolisis unit are conducted to a mixing and dosing unit.
• (4) which controls the addition of hydrogen .to obtain the deserable composition.
• the gas with a specific composition is conducted to the gasometer (5), which supplys the storage units (6) for the application of the gas.
• Fluxogram of the process - fig. 02 Hydrogen line - the electrolisis unit receives water as raw material from a water treating unit, which receives untreated water from any available water sources (1.2); it consumes a continuous current from rectifyings (1.3) after receiving power from the substation (1.4).
• the oxygen produced is employed in the pyrolisis furnace to correct the stequiometri reaction, when the amount of oxygen in the waste organic material is not sufficient to react with all necessary carbon to produced carbon monoxide (2); the surplus of oxygen is bottled (2.1) for other uses, including hospital, due to the purity of oxygens obtained by the electrolisis process.
• the hydrogen is conducted through it's own line (3) to the mixing-dosing unit, where it is mixed with the gas produced in the pyrolisis unit (5), so that the resultant gas will have the desirable composition and will be conducted to the gasometers (8).
• Pyrolisis gas line - the waste organic material are selected and the inorganic materials are packed then leaped up in a covered area receiving area (5.1) and sold as scrap; as these waste meterials have high humidity, it is stored in a place where it permits the draining of a part of this humidity through a drainager system (5.2).
• the other part of the humidity is removed in the feeding system (5.3) which receives the gas from the pyrolisis furnace (5.5) and in the interior of the furnace, during the pre-heating, the low-humidity waste feeds a grinder (5.4) which breaks up the material in order to permit a homogenious feeding as well as facilitating it's combustion because of the increase of the contact surface; the necessary power for the system is supplied by the substation (1.4) which also supplies the electrolisis unit.
• the gases are removed from the furnace, after supplying the necessary heat for the reduction of the feed humidity, it can be directly burned in a system which does not demand the modification of it's calorific value or it can be conducted to the gasometer, the gas is conducted to the gasometer (6) after being cooled in an proper unit (6.1). From the gasometer, the gas is conducted to the mixing-dosing unit (4) which receives the right amount of hydrogen (3); the mixtures coith the desirable specification is conducted to the respective gasometer (8) and will supply the loading station (09) for the proper employment of the mixture.
