METHOD FOR RECOVERING TRANSITION METAL TETRAHALIDE AND HYDROCARBONS FROM A WASTE STREAM

---

Abstract

---

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.
