An installation for carrying out a continuous multi-stage industrial process includes a housing that defines a first space and a second space that is connected to the first through a first connecting channel. Different pressure conditions prevail in these spaces during the course of the process. A process material is passed sequentially through the first space, the first connecting channel and the second space. A transported material is provided in the first connecting channel to form a free-flowing sealing zone with the process material and ensures that different process conditions will be maintained in the two spaces, and in particular that different pressures will be maintained in the two spaces. The invention also relates to a multi-stage continuous industrial process using such an installation.

A process for producing nanoparticles of a substance, including in a first chamber, forming a dispersion of a substance in a fluid and bringing the fluid into a supercritical state; passing the dispersion from the first chamber through a cooling device or into a cooling zone in a second chamber, wherein the cooling device or cooling zone configured to reduce temperature of the dispersion below a temperature at which the fluid forms solid particles such that nanoparticles of the substance are formed, wherein the second chamber comprises a surface configured to receive the solid particles of the fluid and the nanoparticles of the substance; allowing pressure to decrease and/or temperature to increase in the second chamber to transform the solid particles into a gaseous state, removing the fluid in the gaseous state and with the nanoparticles remaining on the surface; and collecting the nanoparticles from the surface.

The invention relates to an arrangement for continuous production of polymer including a polymerisation reactor. The reactor includes a first pulley and a second pulley arranged at a distance from each other, which distance, defining a longitudinal first direction, and a flexible endless belt having a first edge section and a second edge section, which belt, is arranged to travel over the first pulley and the second pulley as a flat belt. The reactor further includes a supporting structure, which is arranged to support the flexible endless belt between the first pulley and the second pulley, whereby the supporting structure is arranged to form the flexible endless belt into a trough section by deviating the first edge section and the second edge section of the flexible endless belt away from the first direction. The trough section has a width-to-height ratio <1.2.
