| titleOfInvention | Titanium dioxide production process |
| abstract | FIELD: industrial inorganic synthesis. n SUBSTANCE: invention is meant to be used in varnish-and-paint industry, in production of catalysts, dielectrics, and other industries. Titanium dioxide production process is based on conversion of titanium tetrachloride in oxygen plasma into disperse titanium dioxide and chlorine gas. Oxygen plasma stream is generated by several electroarc plasmatrons uniformly distributed across horizontal cross-section of reactor and disposed below feed and rutilization additive entry zone. Feed and rutilization additive (aluminum chloride) are added to plasma stream from above in the form of disintegrated solution of aluminum chloride in titanium tetrachloride. A disintegration additive, namely silicon tetrachloride. is simultaneously added together with oxygen. Feed and indicated additives are stirred with oxygen plasma. Two-phase conversion product stream at the mixing zone outlet is squeezed with tangential stream of return chlorine gas, rutile titanium dioxide and chlorine gas are separated consecutively in cyclone, on metallized cloth and metal-ceramic filters, pigmented disperse titanium dioxide is continuously withdrawn from apparatus and chlorine gas is continuously purified from residual disperse phase and then recycled. n EFFECT: increased yield of rutile modification of titanium dioxide and reactor operation efficiency, reduced titanium dioxide loss and power consumption. n 9 cl, 2 dwg, 1 tbl |
