Valmet’s technology for steam separation in mechanical pulp production provides environmental and energy benefits. Considerable volumes of steam are produced in the making of mechanical pulp. It is generated by, for example, the moisture content of the chips as well as the amount of energy applied when refining the chips to pulp. Harnessing the energy content of the steam is very important. This is achieved by separating the pulp from the steam in a separator. The steam is then carried to a steam reclaiming system to be used elsewhere in the pulp or paper mill.

Steam recycling is an important aspect of the energy-demanding refining process. It is a well-known fact that fiber carryover in the recycled steam can cause problems such as plugging, operating stops for cleaning and, in some cases, emitting fiber and steam into the surroundings.
