Description
- This application is a divisional application of U.S. Ser. No. 09/958,875, filed Oct. 17, 2001.
- The subject-matter of the invention is a plant for polyolefines waste conversion into liquid hydrocarbons.
- Nowadays the utilization of objects made of plastics is an ecologic problem. The known plant with the object to make plastics for utilization comprises the reactor, the raw material dosage system, the condenser of product, the buffer tank and the distillation column. The reactor in form of vertical tank is equipped with the hatch, the raw material receiving connection pipe, the control system and the heating system. The heating system consists of heating tubes which are placed on the tank's surface or within the tank. Such a heating system causes sinter and coke formation.
- A process of the transformation of polyolefine wastes to liquid hydrocarbons is carried out in a plant according to the invention, comprising at least one reactor in a shape of vertical tank, provided with an inlet charging hole, connected to a polyolefine raw material and catalyst dosing device, combustion gases outlet pipe, product receiving pipe, mixer and sieve membrane and a heating system in a form of a combustion chamber surrounding a tank from below and the said chamber is heated with at least one burner, supplied with reaction products, and in the combustion chamber, symetrically distributed on a tank circumference, preferably in some rows, heating pipes are located, which pass throughout inside of the tank above the level of an upper wedge of a mixer and which are led out through sieve membrane to the combustion gases outlet chamber. The plant comprises also a condenser for a product condensation, a raw product buffer tank and a distillation column. Products of the reaction coming out from the reactor through an outlet pipe are cooled and condensed and then are directed to a buffer tank, heated up to 40° C.
- The preferable regulation of a process is achieved, when a buffer tank is provided with a level sensor, included into a raw material dosing device automatic regulation system, ensuring keeping a level of a reactor content at the same range.
- From a buffer tank a product is directed to a distillation column, where fractions of various boiling temperatures are separated.
- The introduction of heating pipes above the upper wedge of a mixer enables more efficient mixing, especially of a bottom zone, an uniform distribution of a catalyst in a reaction mass and remarkably decreases formation of agglomerates and coke.
- FIG. 1 is a schematic view of the apparatus of the present invention.
- FIG. 2 is a side, partially cutaway view of the apparatus of the present invention.
- A plant according to the invention is presented on the enclosed drawing in a form of an exemplary embodiment of the invention.
- A plant comprises one
reactor 1 according to the invention, in a shape of vertical tank, provided with an inlet charging hole 2, connected to a polyolefine raw material andcatalyst dosing device 3, combustion gases outlet pipe 4, product receiving pipe 5,mixer 6 and a sieve membrane 7 and a heating system in a form of acombustion chamber 8 surrounding atank 1 from below and the saidcombustion chamber 8 is heated with at least oneburner 9 supplied with reaction products, and in thecombustion chamber 8, symetrically distributed on a reactor tank circumference, preferably in some rows,heating pipes 10 are located, which pass throughout inside of the tank above the level of an upper wedge of amixer 6 and which are led out through a sieve membrane 7 to the combustion gases outlet chamber. The plant comprises also acondenser 11 for a product condensation, a rawproduct buffer tank 12 and adistillation column 13. The reaction products, coming out from the reactor through a product receiving pipe, are directed to acondenser 11 wherein they are cooled and condensed and then directed to thebuffer tank 12, which is heated to 40° C. - A
buffer tank 12 is provided with a level sensor, included into a rawmaterial dosing device 3 automatic regulation system, ensuring keeping a level of areactor 1 content at the same range, which is for achieving the preferable regulation of a process. - From the
buffer tank 12 raw product is directed to thedistillation column 13, where fractions of different boiling temperatures are separated.
