Spray Nozzle Scrubbers
- Overview
- The absorbent is sprayed downward from a series of nozzles and scrubs the flue gas as it moves upward resulting in SO2 absorption.
- Features
- 1）Having a low pressure drop. 2)Scaling problems are less likely to occur.
Limestone Process
- Overview
- Limestone（CaCO 3 ）slurry absorbs sulfur dioxide (ボンズカジノ 安全性 2) in the absorber and a byproduct as gypsum is generated.
- Features
- 1) Cheap absorbent (limestone), low operating cost. 2) Producing a gypsum by-product to be collected. 3) The amount of wastewater discharge is the smallest.
- Reaction
- ボンズカジノ 安全性2+CaCO3+1/2H2 O →CaSO 3・1/2H2O+CO2 CaSO 3・1/2H2O+1/2O2+3/2H2O
NEOBRID Scrubbers
- Overview
- The absorber tower consists of a combination of MORETANA plates with packing materials. It can remove ボンズカジノ 安全性2 efficiently from the flue gas.
- Features
- 1）Contact area between the gas and liquid is large. 2)Simple process enables the absorber design to be compact.
Seawater Process
- Overview
- Seawater is used as an absorbent to remove ボンズカジノ 安全性 2 from the flue gas.The absorbed ボンズカジノ 安全性 2 is oxidized to soluble sulfate by aeration before discharge to the sea.
- Features
- 1) The absorbent is seawater, no other reagents are necessary. 2) Simple system, easy operation and maintenance. 3) No by-product is generated. 4) The spent seawater can be discharged to sea after aeration.
- Reaction
- ボンズカジノ 安全性2+H2O → HSO3
–+ H+
HSO3 –+1/2O2→ ボンズカジノ 安全性4 2-+ H+
HCO3 –+ H+→ CO2+H2O
[ボンズカジノ 安全性 System] MORETANA Scrubbers
- Overview
- MORETANA is the name given to the perforated plate that has high open area ratio between 25%-60%. It promotes the contact between gas and liquid efficiently and can also treat flue gas containing dust.
- Features
- 1) Higher gas speed in tower and compact structure. 2) High efficiency dust removal. 3) No plugging due to self-cleaning effect.
Mg(OH)2Process
- Overview
- Mg(OH)2 is used as an absorbent to remove sulfur dioxide (ボンズカジノ 安全性2) from the flue gas. The absorbed ボンズカジノ 安全性2 is discharged as MgSO4 aqueous solution.
- Features
- 1) Magnesium hydroxide is another cheap absorbent similar to limestone. 2) Relatively simple and compact system resulting in easy operations and maintenance. 3) No scaling problems. 4) MgSO4 can be discharge to sea
- Reaction
- ボンズカジノ 安全性2+Mg(OH)2→ MgSO3+ H2 O ボンズカジノ 安全性 2+MgSO3+H2O→Mg(HSO3 ) 2 MgSO 3+1/2O2→ MgSO4
Seawater Process
- Overview
- Seawater is used as an absorbent to remove sulfur dioxide (ボンズカジノ 安全性2) from the flue gas. The absorbed ボンズカジノ 安全性2 is oxidized to soluble sulfate (ボンズカジノ 安全性42-) by aeration before discharge to the sea.
- Features
- 1) The absorbent is seawater, no other reagents are necessary. 2) Simple system, easy operation and maintenance. 3) No by-product is generated. 4) The spent seawater can be discharged to sea after aeration.
- Reaction
- ボンズカジノ 安全性2+H2O → HSO3 –+ H+ HSO 3 –+1/2O2→ ボンズカジノ 安全性4 2-+ H+ HCO 3 –+ H+→ CO2+H2O
NaOH Process
- Overview
- NaOH is used as an absorbent to remove sulfur dioxide (ボンズカジノ 安全性2) from the flue gas. The absorbed ボンズカジノ 安全性2 is discharged as ボンズカジノ 安全性2ボンズカジノ 安全性4 aqueous solution. .
- Features
- 1) Simple system and easy maintenance. 2) No scaling problems. 3) Highest ボンズカジノ 安全性2 removal efficiency. 4) Producing ボンズカジノ 安全性2ボンズカジノ 安全性4 as a by-product to be collected.
- Reaction
- ボンズカジノ 安全性2 +2NaOH → ボンズカジノ 安全性 2SO3 + H2 O ボンズカジノ 安全性 2+ボンズカジノ 安全性2ボンズカジノ 安全性3+H2O → 2NaHSO3 NaHSO 3+NaOH → ボンズカジノ 安全性2ボンズカジノ 安全性3+H2 O ボンズカジノ 安全性 2ボンズカジノ 安全性3+ 1/2O2→ ボンズカジノ 安全性2ボンズカジノ 安全性4
