Abstract
The invention relates to a method and an apparatus for cleaning a gasification product (4) formed from plastic-based raw material (3) by means of a gasification. The plastic-based raw material (3) containing chlorine is gasified in the gasification unit comprising at least one fluidized bed gasification reactor (1) in which the gasification is performed to form the gasification product (4). A liquid sorbent composition (6) is sprayed to the gasification product (4), and the gasification product (4) is cooled. The gasification product (4) is supplied at a temperature of below 500° C. to a filter (2) in which solids (8) comprising chloride is removed from the gasification product (4). Further, the invention relates to the use of the method.

A method for cleaning a gasification product formed from plastic-based raw material by means of a gasification wherein the method comprises:
- gasifying the plastic-based raw material containing chlorine in the gasification unit comprising at least one fluidized bed gasification reactor in which the gasification is performed to form the gasification product,
- spraying a liquid sorbent composition to the gasification product, and cooling the gasification product, and
- supplying the gasification product at a temperature of below 500° C. to a filter in which solids comprising chloride is removed from the gasification product.
An apparatus for cleaning a gasification product formed from plastic-based raw material by means of a gasification, in which the apparatus comprises at least a gasification unit for forming a gasification product, wherein the apparatus comprises:
- the gasification unit comprising at least one fluidized bed gasification reactor for gasifying the plastic-based raw material containing chlorine and for forming the gasification product,
- at least one means for spraying a liquid sorbent composition to the gasification product, and optionally at least one cooling device for cooling the gasification product, and
- at least one filter and at least one means for supplying the gasification product at a temperature of below 500° C. to the filter in which solids comprising chloride is removed from the gasification product.
