SULPHURIC ACID / ACID DISTRIBUTION

PROCESS INFORMATION
For effective gas / sulphuric acid contact in the ceramic packing bed in a Drying Tower or Absorbing Tower, the acid must be distributed evenly and consistently over the cross sectional area inside the tower. The type and volume of the packing is also depending on the good distributor performance.

PROBLEMS TO SOLVE
Even distribution per m2 of packing surface / tower cross section area.
Consistent pressure / flow of acid over the tower (no waves in troughs, no significant variations).
Allowing minimum packing height to be installed (cost) or design tower velocity (process), without negative impact on tower performance.
Corrosion resistance without unreasinable high cost impact

DESIGN SOLUTION
Pipe type distributor in cast iron or alloy materials (e.g. SX)
Trough type distributor in alloy materials (e.g. SX)

Begg Cousland can design and supply a range of pipe and trought type acid distributors for H2SO4 plant tower duty.
