Slurry Piping

91-9820277283. Slurry Piping. Slurry piping system, like any other system, consists of slurry pumps, pipelines and valves. Special considerations relevant to this systems are introduced by the fact that slurry in not homogeneous phase (unlike gas or liquid). Slurry can be described as liquid with solids suspended therein.

Crystallization (ZLD)

Crystallization occurs in the forced-circulation evaporator-crystallizer, where we have the generation and augmentation of the crystals within the bulk solution (Fig.1). The evaporator/crystallizer scheme is followed by a dewatering device (centrifuge or pressure filter), which separates the salt crystals from the product slurry.

Wet Scrubber Systems

In wet scrubber systems an alkali sorbent solution (limestone or lime) is injected into the flue gas. The sorbent slurry is injected by using a spray tower. The CaCO3 slurry is sprayed from the top to the bottom and the hot flue gas flows from the bottom to the top of the SO 2 absorber (countercurrent flow system). The alkaline slurry reacts with the SO 2 into calcium sulfite, further ...

Aqueous Slurry

A limestone slurry is used in an open spray tower with in situ oxidation to remove SO 2 and form a gypsum sludge.
