BY-PRODUCT RECOVERY Process

In the Vinnolit process the liquid and gaseous wastes are completely incinerated at approx. 1150 °C.

The heat of the hot combustion gases is exploited to generate steam and the hydrogen chloride is recovered as a valuable feedstock which is returned in gaseous state to the OXYCHLORINATION process. Alternatively, aqueous HCl of 25 to 30 % can be produced.

The treated waste gas complies with all applicable German statutory regulations, including those concerning the concentration of dioxins and furanes (< 0.1 ng TE/m³).

The advantages of the Vinnolit process can be summarized as follows:

· Recovery of hydrogen chloride from the by-products
· Optimum utilisation of the input chlorine to produce VCM
· Utilization of the energy content of the by-products in the form of steam
· Use of proven technology and materials
· Environment-friendly process
