GRANULADO ABSORBENTE ABSORBENT GRANULATE
ANTECEDENTESBACKGROUND
Actualmente, el manejo de residuos ha tomado gran relevancia debido a que muchos de éstos poseen altos niveles de toxicidad y por Io tanto resultan nocivos, si es que no se neutralizan sus posibles efectos y si son altas sus concentraciones, estos incluso si se recuperan, se pueden reciclar ah proceso. Otro tipo de procesos en los cuales cobra gran importancia el manejo de sus residuos, derrames, accidentes y remediación de áreas afectadas es Ia industria petrolera, Ia cual produce residuos altamente tóxicos y contaminantes, los cuales no son fáciles de eliminar. En el pasado se han utilizado diversos medios tanto físicos, como químicos y hasta bacteriológicos para controlar, limpiar o remediar áreas contaminadas. Como las áreas contaminadas pueden estar constituidas por porciones de tierra, agua, etc., Ia diferente naturaleza del medio contaminado, ha establecido una barrera difícil de superar, dado que ha exigido Ia utilización de muy diversos mecanismos los cuales hasta este momento no han sido compatibles entre si. Existe una variedad de patentes que han intentado sin éxito limpiar una corriente o un elemento contaminado por compuestos orgánicos de diversas maneras, tanto líquidas como gaseosas, e incluso por medio de sólidos, mezclados con agentes nutrientes y micro organismos ávidos de dichos derivados orgánicos. La patente US 5,525,255 de Leadingham, et al (jimio 1996) describe un agente no tóxico para limpieza, el cual es neutro, contiene un surfactante, etoxilato de nonilfenol y un agente humectante como el sulfonato de alqueno, para remover aceites y grasas. La composición tiene una base acuosa y puede usarse en combinación con sistemas de biodegradación sin detrimento de los micro organismos que realizan Ia destrucción de los desechos. En Ia patente US 6,471,864 de Sublette, et al (octubre, 2002) se describe un biocatalizador en Ia forma de esferas adsorbentes. Las esferas son altamente porosas y constituidas por hexa metilen dipamida o caproamida, con carbón activado dispersado a través del polímero y del material biocatalítico y localizado dentro de los macroporos de las esferas. El material biocatalítico consume los contaminantes orgánicos y algunos inorgánicos, los cuales son absorbidos por el carbón activado y se metaboliza el contaminante en productos inocuos, mientras que se renueva Ia capacidad absortiva del carbón activado de manera continua. La patente US 6,828,141 de Kataoka, et al (diciembre, 2004) describe un método para purificar materia contaminada con un compuesto orgánico halogenado, que incluye añadir a Ia materia contaminada un agente reductor y una fuente nutricional para un organismo anaeróbico heterotrófico. El agente reductor es hierro reducido, hierro fundido, aleación de hierro-silicio o un compuesto soluble en agua. Una combinación de reacciones químicas con los micro organismos permite descomponer los compuestos orgánicos halogenados. La fuente nutricional incluye un carbono orgánico y de un 20 a un 50% por peso de una forma oxidada de nitrógeno, Io cual se añade para prevenir subproductos de Ia descomposición, tales como gases nocivos y decoloración del substrato. En una forma de Ia invención, se incluye Ia mezcla de un agente reductor y un líquido nutricional con Ia materia contaminada, se ajusta el pH a un rango entre 4.5 a 9.0 y se mantiene Ia mezcla en una condición en Ia cual el aire difícilmente penetra a través de una matriz, permitiendo mezclar uniformemente una gran cantidad de Ia materia contaminada.Currently, waste management has taken great relevance because many of these have high levels of toxicity and therefore are harmful, if their possible effects are not neutralized and if their concentrations are high, these even if they recover, You can recycle process ah. Another type of process in which the management of its waste, spills, accidents and remediation of affected areas becomes very important is the oil industry, which produces highly toxic and polluting waste, which is not easy to eliminate. In the past, various physical, chemical, and even bacteriological means have been used to control, clean or remediate contaminated areas. As the contaminated areas can be constituted by portions of land, water, etc., the different nature of the contaminated environment has established a difficult barrier to overcome, since it has required the use of very diverse mechanisms which until now have not been compatible with each other. There are a variety of patents that have tried unsuccessfully to clean a stream or an element contaminated by organic compounds in various ways, both liquid and gaseous, and even by means of solids, mixed with nutrient agents and micro organisms eager for such organic derivatives. US Patent 5,525,255 by Leadingham, et al (Jimmy 1996) describes a non-toxic cleaning agent, which is neutral, contains a surfactant, nonylphenol ethoxylate and a wetting agent such as alkene sulphonate, to remove oils and fats. The composition has an aqueous base and can be used in combination with biodegradation systems without detriment to the micro organisms that carry out the destruction of the waste. In US Patent 6,471,864 of Sublette, et al (October, 2002) a biocatalyst in the form of adsorbent spheres is described. The spheres are highly porous and constituted by hex methylene dipamide or caproamide, with activated carbon dispersed through the polymer and biocatalytic material and located within the macropores of the spheres. The biocatalytic material consumes organic and some inorganic pollutants, which are absorbed by activated carbon and the contaminant is metabolized into harmless products, while the absorptive capacity of activated carbon is continuously renewed. US Patent 6,828,141 to Kataoka, et al (December, 2004) describes a method for purifying contaminated matter with a halogenated organic compound, which includes adding a reducing agent and a nutritional source to a heterotrophic anaerobic organism to the contaminated matter. The reducing agent is reduced iron, cast iron, iron-silicon alloy or a water soluble compound. A combination of chemical reactions with micro organisms allows the decomposition of halogenated organic compounds. The nutritional source includes an organic carbon and 20 to 50% by weight of an oxidized form of nitrogen, which is added to prevent byproducts of decomposition, such as harmful gases and discoloration of the substrate. In a form of the invention, the mixture of a reducing agent and a nutritional liquid with the contaminated matter is included, the pH is adjusted to a range between 4.5 to 9.0 and the mixture is maintained in a condition in which the air hardly penetrates through a matrix, allowing a large amount of contaminated matter to be mixed uniformly.
La patente US6,905,603 de Mirzayi, et al Q'unio. 2005) describe un tratamiento de carbón activado contaminado, por medio de un tratamiento fluido que incluye una zona de tratamiento que contiene carbón activado granulado y una corriente de agua que contiene nutrientes, microbios degradantes de Ia contaminación y oxígeno disuelto e introduce Ia corriente a una zona de tratamiento para efectuar Ia absorción de los nutrientes y los microbios en el carbón granular activado para proveer una matriz de tratamiento en donde se reduce el contaminante en un flujo fluido a través de Ia matriz.US Pat. No. 6,905,603 of Mirzayi, et al Q ' unio. 2005) describes a treatment of contaminated activated carbon, by means of a fluid treatment that includes a treatment zone that contains granulated activated carbon and a stream of water that contains nutrients, microbes degrading pollution and dissolved oxygen and introduces the current to a treatment area to effect the absorption of nutrients and microbes in activated granular carbon to provide a matrix of treatment where the contaminant is reduced in a fluid flow through the matrix.
Como puede observarse de los procesos y productos anteriormente descritos, se han intentado un sin número de medios para Ia remoción de contaminantes de corrientes que portan compuestos orgánicos, pero ha sido tal Ia dificultad para hacerlo que se han tenido que intentar mecanismos diversificados para diferentes corrientes y el éxito alcanzado ha sido relativo, razón por Ia cual aun subsiste el problema.As can be seen from the processes and products described above, a number of means have been tried for the removal of pollutants from streams that carry organic compounds, but it has been such a difficulty to do so that diversified mechanisms have been attempted for different streams and the success achieved has been relative, which is why the problem still exists.

Additionally, the recovery, regeneration and recycling of a substantial amount of the organic compound from the effluents allows higher levels of the organic compounds to be reused thereby reducing operating costs. The product consists of a GALP hazardous liquid absorbent granulate comprising rubber and vulcanized rubber, natural and synthetic, carbon and absorbent fibers such as polyester, nylon and rayon, in combination proportions ranging from 1% rubber-rubber and 99% fibers absorbents up to 1% absorbent fibers and 99% rubber-rubber, with a reduced particle size, insoluble in water, of lower density than the same and neutral pH. In a first stage the solution or effluent containing the organic compound to be removed is uniformly covered with GALP hazardous liquid absorbent granules. At the time of being spread on the organic compound, the absorbent granulate immediately absorbs the organic compound and by virtue of the greatly enlarged contact surface of the granulate, it can absorb a significant amount of the organic compound.
En una segunda etapa del proceso, el material granulado absorbente de líquidos peligrosos GALP que ha absorbido al compuesto orgánico, se recolecta por diversos medios y se deposita o almacena, de tal manera que pueda ser dispuesto de forma definitiva, o enviado a proceso para recuperar y regenerar el compuesto orgánico absorbido. El utilizar el granulado absorbente de líquidos peligrosos GALP favorece un excelente contacto con el compuesto orgánico, ya que éste se ha dotado de una superficie de contacto muy aumentada, Ia cual propicia Ia rápida absorción sobre Ia misma que hace un contacto efectivo con el compuesto orgánico. El granulado absorbente requiere mucho menos espacio que otros productos para usos similares Io que resulta en una significativa reducción de costos.In a second stage of the process, the GALP hazardous liquid absorbent granulated material that has absorbed the organic compound, is collected by various means and deposited or stored, so that it can be permanently disposed, or sent to process to recover and regenerate the absorbed organic compound. The use of the GALP hazardous liquid absorbent granulate favors excellent contact with the organic compound, since it has been provided with a very increased contact surface, which favors the rapid absorption on it which makes an effective contact with the organic compound . The absorbent granulate requires much less space than other products for similar uses, which results in a significant cost reduction.
Para Ia manipulación del granulado absorbente de líquidos peligrosos GALP no se requiere de medidas especiales por ser un material inerte, químicamente estable, sin fecha de caducidad, cuya transportación no requiere de transportes especiales.For the manipulation of the absorbent granulate of dangerous liquids GALP no special measures are required because it is an inert material, chemically stable, without expiration date, whose transportation does not require special transport.
Pruebas experimentales a nivel planta piloto se llevaron a cabo tanto a modo de pruebas de naturaleza discontinua (por cargas), como continua. Se esparció el granulado absorbente de líquidos peligrosos GALP con una granulometría en el rango de 0 a 1.25 mm sobre efluentes conteniendo diversas corrientes de compuestos orgánicos, de tal manera, que el granulado absorbente de manera sorpresiva rápidamente absorbió Ia comente de compuestos orgánicos, los cuales fueron rápida y fácilmente retirados del efluente de manera sencilla y segura, de tal manera que el efluente quedó virtualmente libre de los compuestos orgánicos, los cuales fueron dispuestos en contenedores.Experimental tests at the pilot plant level were carried out both as tests of a discontinuous nature (by loads), as well as continuous. The GALP hazardous liquid absorbent granulate was spread with a particle size in the range of 0 to 1.25 mm over effluents containing various streams of organic compounds, such that the absorbent granulate surprisingly quickly absorbed the organic compound comment, which they were quickly and easily removed from the effluent in a simple and safe manner, so that the effluent was virtually free of organic compounds, which were arranged in containers.
