Flue-gas desulfurization - Wikipedia 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime ...

Leak rate calculator - LMNO Eng rate is one application where it is widely used. Since a pipe is usually much larger diameter than the hole, V 2 >>V 1 . Since the elevation change Z 2 -Z 1 is typically very small compared to other terms in the Bernoulli equations for a pipe leak application, Z 2 -Z 1 =0.
