Definitions
- the invention relates to a process for the production of phosphate and multi-nutrient fertilizers from regenerative phosphate-containing wastes.
- Phosphorus is an essential element for all living things. Its functions, for example as a component of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) and as a key element in the energy metabolism in the form of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) can not be replaced.
- ADP adenosine diphosphate
- ATP adenosine triphosphate
- phosphorus is removed from the crop by plant growth and the subsequent harvest, it must be returned to maintain the productivity of the site. This is partly due to the use of organic manure, but also due to the supply of mineral phosphorous based on rock phosphate.
- the sources of raw materials are finite. The static range is about 100 years. Newly opened raw phosphate sources are usually characterized by rising production costs and sometimes high pollutant contents (cadmium, fluorine,). Europe is importing raw phosphates or phosphorus fertilizers
- thermochemical process for the treatment of these ashes was intensively investigated in the SUSAN project.
- the aim of the thermochemical process is the removal of heavy metals and the conversion of the phosphorus into plant-available compounds.
- the ash from the monoburning of municipal sewage sludge is mixed with a chlorine donor.
- the mixture is treated in a rotary kiln at 850 to 1000 degrees Celsius for about 20 minutes. This leads to thermochemical reactions of the chlorine donor with components of sewage sludge ash.
- Volatile heavy metal chlorides and oxychlorides are formed, which evaporate at the set temperatures and via the gas phase be separated.
- the phosphate-containing mineral phases are being rebuilt to produce plant-available phosphorus compounds.
- thermochemical treatment of the main mass flow into a usable product - a secondary raw material for the production of phosphate fertilizers - transferred Only a small mass fraction of about 2 to 3 percent by weight of the ash used is removed in the form of a heavy metal concentrate. The processing of this concentrate with the aim of recycling the individual extracted pollutants is currently being worked on.
- thermochemical process for the treatment of ashes from the mono-incineration of municipal sewage sludge the development of the overall technical concept, the product design, the fertilising effect of ash-based fertilizers and the sustainability of the analyzed sewage sludge utilization option are still in the foreground of the project.
- the scarcity of this resource in 2007 was accompanied by significant price increases and significantly reduced availability.
- the average phosphorus content of ashes from the mono-combustion of municipal sewage sludge is 8.7 percent P2O5, or 20 percent P205.
- the levels of marketable fertilizers such as Single Super Phosphate (SSP) are about 18 percent P2O5 and the of complex fertilizers - for example, phosphorus-potassium and nitrogen-phosphorus-potassium fertilizers (PK-NPK fertilizers) - at 5 to 12 percent P2O5.
- SSP Single Super Phosphate
- PK-NPK fertilizers phosphorus-potassium and nitrogen-phosphorus-potassium fertilizers
- the thermal treatment also lacks the nitrogen component, so that the fertilizer obtained in this process is not an NPK fertilizer, ie no complete fertilizer.
- NPK fertilizer ie no complete fertilizer.
- nitrogen and potassium carrier means that two differently acting and thus not relevant for a fertilizer cycle fertilizer are combined.
- silicon does not play a role as a nutrient in fertilizers, it does not have any negative effects, but rather is regarded as a soil improver.
- thermo-chemical methods are described in shaft furnaces, in which mixtures of different substances heavy metals be trapped in slag the.
- BAM Federal Institute for Materials Research and Testing
- the prescribed procedures can be used to produce phosphate-containing fertilizers, which are largely not used as multi-nutrient Fertilizers (complete fertilizers) and which are also no multi-nutrient fertilizers, since their application has only limited positive effects on agricultural soils.
- the present invention has for its object to provide a process for the production of phosphate and multi-nutrient fertilizers from renewable phosphate-containing recyclables such as ashes from the mono-combustion municipal sewage sludge, which are directly used in agricultural areas.
- a fertilizer, a phosphate and multi-nutrient fertilizer which is an NPK (S) fertilizer
- NPK NPK
- the phosphate carrier which is also a phosphate fertilizer, is a mineral acid-chemically treated ash from mono-incineration of municipal sewage sludge-based phosphate carriers, the phosphorus portion of which is up to 95% water-soluble and thus directly available to the plant and granulated.
- a nitrogen and potassium carrier which also reacts with the mineral acid during the chemical neutralization of the ash from the mono-combustion of municipal sewage sludge, a NP, NPK or PK complex fertilizer is produced.
- the magnesium contained in the starting material is the alkaline earth element.
- alkaline earth salts and / or ammonium sulfate compounds are added.
- the addition is carried out according to the invention, characterized in that from the crushed ash from the mono-combustion municipal sewage sludge from the mono-combustion, together with the said alkali metal salts, for.
- potassium sulfate and by mixing in a known manner produces a mixture to which a certain amount of orthophosphoric acid defined quality is added, as given equation (3.1).
- the calcium phosphate carrier corresponds in content to a (Ca, Mg) -phosphate, the stanfildite / whitlockite, [Ca 4 Mg 5 (PO 4 ) 6 / (Ca 9 (Mg, Fe) [HPO 4 / (PO 4 ) 6 ].
- the proportions of the components are chosen so that for technical reasons, 1 mole of Ca 4 Mg5 (PO 4 ) 6 with 11 moles of ⁇ 3 ⁇ 4 ⁇ 2 ⁇ 2 ⁇ implemented.
- the proportions of potassium and nitrogen carriers can be adapted to later recipe and demand specifications.
- Equal neutralization reactions can also be carried out with other mineral acids, for example hydrochloric, nitric or sulfuric acid individually or in combination of these acids with orthophosphoric acid.
- reaction can be carried out in a known manner in a continuous or batch process.
- the granules then undergo a drying process that depends on the previous process.
- NPK (S) fertilizer has numerous advantages over the phosphate fertilizer obtained from the monoburning of municipal sewage sludge from the ash.
- the phosphate and multi-nutrient fertilizer, NPK (S) fertilizer is produced in a major constituent of a calcium phosphate carrier from a regenerative feedstock, preferably from the ash from municipal sewage sludge mono-combustion
- orthophosphoric acid and / or another mineral acid in the starting raw material only the citrate-soluble phosphate is converted into a water-soluble phosphate, thereby the prerequisite was created to use this starting material for further use as raw material for industrial application and more, according to the fertilization period required mineral, water-soluble Nutrient components, such as potassium salts and nitrogen carriers incorporate that the final product is so low in pollutants that it meets the requirements of the Fertilizer Ordinance and thus an additional expensive cleaning, ie separation of Heavy metals before processing
- Another advantage is that in this process, the water formed during the reaction is used simultaneously for the dissociation of the reactants and for the setting of the resulting calcium sulfate (gypsum) and for the formation of granules. Due to the associated reduction of the drying effort, the process is very energy efficient.
- ammonium sulfate ammonium phosphate, urea and potassium sulfate are combined in a batch mixer type plowshare mixer with knife set or a continuous flow mixer according to the following quantitative batch and formulated into a homogeneous mixture and with orthophosphoric acid reacted with a concentration of 52.5% P2O5.
- the proportion of stanfildite / whitlockite in an ash from the mono-combustion of municipal sewage sludge with 19-20% P2O5 is about 36%.
