Free allocation - European Commission
The revised ETS Directive introduced the concept of an EU-wide, harmonised, approach for the allocation of allowances. It provides that for the third phase of the ETS (2013-2020) full auctioning is the rule for the power sector and that a transitional system for free allocation, based on benchmarks, has been put in place for other sectors.

Erosion in a paper mill is also a concern. Erosive slurries including pulp stock and lime mud can severely erode the internals of control valves, thus minimizing the service life of the product. In some cases, the erosion is severe enough to cause pressure boundary parts to become unstable. This is a safety risk to the mill.

Tandem rolling mill - Wikipedia
A Tandem rolling mill is a Rolling mill with 2 or more close-coupled Stands, each of which is setup for rolling by using its Spring Curve and the Compressive Curve of the metal so that both the Rolling Force and the exit thickness of each Stand are determined.. The main advantages of a Tandem Mill are: only one single pass is required which saves time and increases production; …
