Group Developments
Water Purification
In order to obtain water of high quality of purification, Coral GROUP has developed a liquid drinking water purifier. The purification process is simple, and does not require electrical power, can be performed in any jug. Because of the long lifetime of the product and its biological properties, one of its usages is as stock for emergency supply of water.
The coagulant works as follows, the presence of polymeric hydroxychloride forms with big molecular weight is the favorable distinctive feature of effectiveness of the product. It differs from such traditional coagulants and flocculants used in technology of water filtering as aluminium sulphate and ferric sulphate and polyacrylimide.
The activity of the produced polymer is provided by the purity of the technology and use of analytically selected and experimentally confirmed catalysators and stabilisation additives.
Tire Recycling
Coral GROUP has developed an ecologically clean method of recycling of worn-out automobile tires (WAT). The soft pyrolysis method for recycling of WAT is an innovation technique that uses an electro - magnetic field principle to ensure uniform heating of WAT, without access of oxygen.
Pyrolysis is the chemical decomposition of organic materials by heating in the absence of oxygen or any other reagents, except possibly steam.
The by-products of this process are extremely light oils, that can are converted into benzene, kerosene, diesel, propane-butane-divinil gasses, scrap metal and carbon, which is converted into a substitute for carbon black.
Rubber Devulcanization
A new method developed in Coral is a process of rubber devulcanisation, which includes impregnation of rubber with special solvent with additives of catalysts and reagents. In this process rubber is restructured, sulfuric "bridges are torn up, sulfur chemically connects, and rubber becomes plastic, suitable for molding. All that remains is to add 2-4% of sulfur, and new rubber products can be made. The quality of the obtained rubber compound is not worse than obtained from the initial materials, i.e. it is completely possible to make new automobile tires of other rubber products from the devulcanised rubber.
The technological solution developed consists of chemical, mechanical and physical stages, performed on the used rubber which yield a “devulcanisate” - a mix that can be further used, with addition of standard vulcanization compound in low percentage, to produce new rubber products.
Plastic Recycling
The most perspective direction in coal gasification is the method of heating young coals with donors of hydrogen to temperatures above 450C at atmospheric pressure. Using special solvents provides conditions for carrying out the process and an output of the liquid products practically identical to natural oil. Also in this process gas is produced, suitable for comprimation and use on transport. Moreover, this process produces coke. An output of coke from young coals is 50-55%, oil of 35% and 10%-15% of gas. A furnace of an original design allows using bad quality - cheap coals, provides high efficiency - 100 thousand tons a year, and most importantly - quality of products and profitability of manufacture. Coke is suitable for domain production.
The above method of coal gasification uses a special solvent produced from polyethylene. This solvent not only gets rid of the polyethylene products, but in the same time increases the percentage of young coals in coke production.
