A method for recovering transition metal tetrahalide and hydrocarbons from a waste stream |
摘要 |
<p>The present invention provides a process for recovering transition metal tetrahalides from a waste stream coming from a catalyst manufacturing process by (a) establishing a mixed stream comprising transition metal tetrahalide and transition metal alkoxyhalides; (b) forming a falling liquid film from the mixed stream of step (a) at a temperature of from 25 to 85 °C and an absolute pressure of from 0.05 to 0.6 bar; and (c) establishing from the film of step (b) a first vapour stream containing from 90 to 100 % of recoverable components and a second liquid stream containing about 10 to 80 % of titanium haloalkoxides.</p> |
