Additive eductors are used, for example, to introduce PVC additives into reactors and condensers with the aid of steam. This can prevent polymer deposits during PVC production.
- Starting the steam supply heats the nozzle in the eductor.
- In the next step, the additive is metered into the motive steam using an atomizer nozzle and mixed.
- The steam serves as a transport medium for the additive, which is introduced into the reactor through a pipeline.
- The mixture then condenses on the reactor wall, leaving a protective film there.
