Purine treatment method for the production of a product with a high calorific value

Abstract

The invention relates to a method for the purification of lignin, cellulose and hemicellulose obtained from purines, which can be burned in compliance with environmental standards as a substitute for wood. The method of the invention produces a novel bio-fuel.

1 . Method for the treatment of purines CHARACTERIZED because it includes the stages:
 a) Feeding the system from three alternative paths to a wash tank.   b) Washing of initial material in the pond by means of rotary movements and/or ultrasound and water drag.   c) Addition of coagulating agents, detergents and/or flocculants.   d) Addition of a continuous flow of clean water inside the Physical and/or Chemical Wash Tank.   e) Separation of Liquids and Solids.   f) Pressing or spinning the finished material. g) Drying of the material resulting from the previous step. h) Shredding and pressing to remove residual water from the Press process to remove water from the lignin   i) The material that has been processed is incorporated into the Pelletizing process.   j) Obtaining lignin pellets or briquettes.   
     
     
         2 . Method for the treatment of slurry according to  claim 1  CHARACTERIZED because in stage a) Feeding the system from three alternative paths to a wash tank, the first alternative includes feeding the system (step  1  (A)) of the material coming from the purinera through a conveyor screw which, with a liquid filtration, which optionally can be pre-washed through water of step  30 , is inserted by the upper part of the screw. Optionally, through step  6 , enter a milling and then go directly to step  10  where it enters the Pond of Physical and/or Chemical Washing. On the other hand, if step  7  is chosen, the material arrives directly to the aforementioned pond. 
     
     
         3 . Method for the treatment of slurry according to  claim 1  CHARACTERIZED because in stage a) Feeding the system from three alternative paths to a wash tank, the second alternative includes feeding the system (step  2  (B)) by A Purine Pump, which takes the slurry and pushes it through a hose leading to step  3 , which is a traditional liquid and solids separator, is fed by water through step  29 . The material that has been separated by the Liquid and Solids Separator can be directed through two independent flows, these are step  4  and step  5 . Step  4  consists of taking the material that has been treated by the separator and takes it directly to the Wash Tank Physical and/or Chemical. Optionally, step  5  can be used, 
     
     
         4 . Method for the treatment of slurry according to  claim 1  CHARACTERIZED because in stage a) Feeding the system from three alternative paths towards a wash tank, a third alternative of feeding the system ((C)) uses the Pile of Purines, which corresponds to that formed by waste of the liquid and solid separators from purineras and/or biogas plants or accumulation of dung, optionally passing through step  8  to the milling at step  10  to the Physical and/or Chemical Wash Tank, or through step  9  directly to the Pond of Physical and/or Chemical Washing. 
     
     
         5 . Method for the treatment of purines CHARACTERIZED because it includes the stages of the process according to FIG. 1. 
     
     
         6 . Fuel product obtained by the method of  claim 1  CHARACTERIZED because it has a high calorific value, emits a low amount of toxic gases and ash when it is calcined. 
     
     
         7 . Fuel product obtained by the method of  claim 1  characterized in that said product has a higher calorific value between approximately 4,200 Kcal/Kg at 5,700 Kcal/Kg. 
     
     
         8 . Fuel product obtained by the method of  claim 1  characterized in that said product has a calorific value. lower between approximately 4,000 Kcal/Kg at 5,300 Kcal/Kg. 
     
     
         9 . High quality fuel product obtained by the method of  claim 1  characterized in that it is in a compacted form, forms including, without limitation, briquettes, pellets, or other high density mold. 
     
     
         10 . Use of high quality fuel product obtained by the method of  claim 1  characterized by being useful as fuel in boilers for the generation of electric power or air conditioning.
