Abstract

Liquid, oily and chemical waste materials is stored and disposed of, using a TEPYRAB material, which is produced from sand, lime, cement and water to which Al powder is added before processing to Ca silicate hydrate granules. The TEPYRAB is used to absorb e.g. hydrocarbons, before intermediate storage and subsequent pyrolysis. ADVANTAGE - Protection of waste until pyrolysed to give a coke with superior surface characteristic

1. Das technische Gebiet, zu dem die Erfindung gehört, ist die Entsorgung und Zwischenlagerung der oben bereits bezeichneten flüssigen, dispersen, sowie öligen und chemischen Abfallstoffe.1. The technical field to which the invention belongs is disposal and intermediate storage of the liquid, disperse, and oily and chemical waste.

2. Nach Kenntnis des Erfinders und Anmelders ist der Stoff TEPYRAB in dieser Zusammensetzung noch nie zur Anwendung gelangt.2. To the knowledge of the inventor and applicant, the substance TEPYRAB is in this composition has never been used.

3. Das Problem ist die Lösung der aktuellen Entsorgungsproblematik zu Lande mit dem oben beschriebenen Stoff.3. The problem is solving the current disposal problem too Land with the stuff described above.

4. Der Schutz wird insbesondere für die unten noch näher beschriebene Zu­ sammensetzung begehrt, nämlich daß dem Granulat unmittelbar nach der Absiebung zur Körnung von 0,1 bis 1 mm von gleicher Körnung eine Zu­ gabe von 4% Calciumcarbonat zugegeben wird, um das Aufschäumen und die Wärmeentwicklung bei der Absorbtion von Säuren oder ähnlichen Schad­ stoffen abzuschwächen und den Neutralisierungsprozeß zu beschleunigen.4. Protection is particularly important for the Zu described below composition, namely that the granulate immediately after the Sifting to the grain of 0.1 to 1 mm of the same grain is a Zu administration of 4% calcium carbonate is added to the foaming and Development of heat when absorbing acids or similar damage weaken substances and accelerate the neutralization process.

5. Die Anwendung dürfte offensichtlich sein und trifft insbesondere die Fälle von unumgänglichen notwendigen Entsorgungen zu Lande jeglicher Schadstoffe. 5. The application is likely to be obvious and particularly affects that Cases of inevitable necessary disposal on land any Pollutants.  

6. Besonders vorteilhaft ist die Tatsache, daß eine unbegrenzte Zwischen­ lagerung der entsorgten Materie bis zur endgültigen Entsorgung möglich ist.6. Particularly advantageous is the fact that an unlimited intermediate Storage of the disposed of matter possible until final disposal is.

7. Im weiteren folgt nunmehr die exakte und genaue Beschreibung.7. The exact and exact description now follows.

TEPYRABTEPYRAB a) Stoffbeschreibung:a) Description of the substance: Herstellung:Manufacturing:

TEPYRAB wird aus den feinstgemahlenen Bestandteilen Sand, Kalk, Zement unter Zugabe von Wasser zu einem Schlamm verarbeitet, dem zuletzt noch Aluminiumpulver zugesetzt wird.TEPYRAB is made from the finely ground components of sand, lime and cement processed with the addition of water to a sludge, the last one Aluminum powder is added.

Abgefüllt in Formen quillt diese Mischung zwischen 50 und 90 Minuten, wobei eine poröse noch plastische Masse entsteht, die unmittelbar da­ nach bei einem Druck von 12-16 Atü im Autoclaven unter Einwirkung von abgesättigtem Wasserdampf ausgehärtet wird.Filled in molds, this mixture swells between 50 and 90 minutes, creating a porous yet plastic mass that is immediately there after at a pressure of 12-16 Atü in the autoclave under the influence of saturated water vapor is cured.

Aus den so entstandenen Kalciumsilicathydratblöcken stellt man mecha­ nisch ein Granulat her mit einer Körnung von 0,1 bis 1 mm.The resulting calcium silicate hydrate blocks are used to make mecha nisch granules with a grain size of 0.1 to 1 mm.

Aus dem Herstellungsvorgang und den Ingredienzien ist ersichtlich, daß es sich um eine ungiftige, nicht canzerogene Substanz handelt.From the manufacturing process and the ingredients it can be seen that it is a non-toxic, non-cancerogenic substance.

b) Eigenschaften und Anwendungsmöglichkeiten:b) Properties and possible uses:

TEPYRAB ist geeignet als Absorber folgender Abfallstoffe, die es auch unter Druckbelastung und bei Erschütterungen festhält.TEPYRAB is suitable as an absorber of the following waste materials, which it also holds under pressure and shocks.

  • - Sämtliche wässerige/ölige Lösungen und Dispersionen der Petrochemie einschließlich Polychlorierten Biphenylen (PCB);- All aqueous / oily solutions and dispersions in petrochemicals including polychlorinated biphenyls (PCB);
  • - Umweltgefährdende Chemikalien;- Environmentally hazardous chemicals;
  • - Kontaminierte Klärschlämme.- Contaminated sewage sludge.
c) Zwischenlagerung und Entsorgung:c) Interim storage and disposal:

Nach Absorbtion der vorgenannten Stoffe kann das bis zur Sättigung be­ lastete TEPYRAB problemlos und umweltfreundlich unbegrenzt zwischenge­ lagert werden.After absorption of the aforementioned substances, this can be until saturation TEPYRAB easily and environmentally friendly be stored.

Die Entsorgung erfolgt über Pyrolyseanlagen.The disposal takes place via pyrolysis plants.

Bei der Verschwelung in der Pyrolyseanlage wird das anfallende Schwel­ gas in einem anschließenden Hochtemperaturbereich aufbereitet und nach Abkühlung als Pyrolysegas bzw. Nutzgas in Gasmotoren oder Kesselan­ lagen zur Wärme- bzw. Stromgewinnung genutzt.The smoldering that occurs in the pyrolysis plant becomes smoldering gas processed in a subsequent high temperature range and after Cooling down as pyrolysis gas or useful gas in gas engines or boilers were used for heat or electricity generation.

Der in der Pyrolyseanlage anfallende Pyrolysekoks, der in einer Weiter­ behandlung als aktivkohleähnliches Filtermaterial Verwendung findet, wird in dieser Eigenschaft durch die Eingabe von TEPYRAB noch ver­ bessert.The pyrolysis coke produced in the pyrolysis plant, the one in another treatment is used as an activated carbon-like filter material, is still ver in this property by entering TEPYRAB improves.

Dem Granulat wird unmittelbar nach der Absiebung zur Körnung von 0,1 bis 1 mm von gleicher Körnung eine Zugabe von 4% Calciumcarbonat zu­ gegeben, um das Aufschäumen und die Wärmeentwicklung bei der Absorbtion von Säuren abzuschwächen und den Neutralisierungsprozeß zu beschleu­ nigen.The granulate becomes a grain of 0.1 immediately after sieving up to 1 mm of the same grain size, add 4% calcium carbonate given to the foaming and heat development during absorption mitigate from acids and accelerate the neutralization process nigen.

Aufgrund seines Grundstoffes (Calciumsilikathydrat) kann TEPYRAB her­ vorragend zur Entsorgung von Urin bzw. Gülle-Seen verwendet werden. Das abgesättigte TEPYRAB kann wie normaler Dünger ausgebracht werden. Seiner Struktur entsprechend würde sich TEPYRAB allmählich mit dem Erdboden vermischen bzw. im Erdboden auflösen und den Charakter eines Langzeitdüngers bewirken.Because of its basic material (calcium silicate hydrate) TEPYRAB can be used can be used excellently for the disposal of urine or liquid manure lakes. The saturated TEPYRAB can be applied like normal fertilizer. According to its structure, TEPYRAB would gradually become familiar with the Mix soil or dissolve in the soil and the character of a Slow release fertilizer.

TEPYRAB eignet sich ebenfalls in idealer Wirkungsweise als Absorber für Lackschlämme.TEPYRAB is also ideally suited as an absorber for paint sludge.

Then there is an upgrade based on the mineral sub stamping from TEPYRAB with simultaneous improvement of the surface finish Pyrolysis coke after pyrolysis. To this extent, the protection up to the manufacturing stage of pyrolysis coke with the sequence just described desires. Pyrolysis coke is needed commercially when using industrial ones Filter systems of any kind (behavior similar to activated carbon).
