Abstract
A process (and a related system) for collecting samples of a polymerization catalyst or of a catalyst-containing polymer from an operation unit, having an upper end and a lower end, of a polymerization plant, including the steps of: a) extracting a prefixed amount of product from the lower end of the operation unit through a discharge valve; b) directing the product towards a filtering unit through an inlet valve; c) flushing an inert gas through the filtering unit; d) outgassing the filtering unit, through the outlet valve; and e) displacing the filtering unit, for collecting the sample.

A process for collecting samples of a polymerization catalyst or of a catalyst-containing polymer from an operation unit, comprising an upper end and a lower end, of a polymerization plant, comprising the steps of:
- a) extracting a prefixed amount of product from the lower end of the operation unit through a discharge valve;
- b) directing the product towards a filtering unit through an inlet valve;
- c) flushing an inert gas through the filtering unit;
- d) outgassing the filtering unit, through an outlet valve;
- e) displacing the filtering unit, for collecting the sample.
A system for collecting samples of a polymerization catalyst or of a catalyst-containing polymer from an operation unit, comprising an upper end and a lower end, of a polymerization plant, wherein the system comprising:
- a discharge valve, connectable to the operation unit, for extracting a predetermined amount of product from the lower end of the operation unit;
- an inlet valve for conveying the product to a filtering unit;
- a filtering unit for filtering the product, the filtering unit being displaceable;
- a first inert gas inlet valve for flushing an inert gas through the filtering unit;
- an outlet valve for outgassing the filtering unit;
- and
- connection piping.
