desulfurization synergist for steel enterprises project

time: 2019-05-15

limestone-gypsum wet flue gas desulfurization system,1# desulfurization system is two furnaces and one tower, 2# desulfurization system is one furnace and one tower. when the so2 concentration of the desulfurization inlet is about 1000 mg/nm3, the outlet so2 concentration will rise to about 50 mg/nm3. 1# desulfurization and 2# desulfurization systems are equipped with three circulating pumps.

it is necessary to increase the sulfur content of raw materials by 20~30%, that is, the inlet so2 concentration is increased from 1000mg/nm3 to 1200mg/nm3, and the export so2 emission is ensured not to exceed the standard.

application

stage 1: add desulfurization synergist, stop a slurry circulating pump, increase the sulfur content of the inlet and observe the desulfurization efficiency.

stage 2: three slurry circulating pumps are operated at the same time, increasing the inlet sulfur and observe the limit value at which the sulfur can be increased.

operational results

stage 1:comparative results

1# desulfurization system

2# desulfurization system

the above data shows that after the addition of the desulfurization synergist, the sulfur content of the desulfurization system is significantly reduced.

stage 2: comparative results

unit:mg/nm3

from the above operational data, it can be seen that under the operation of the three pumps, the maximum sulfur content of the inlet is increased by 32-44%, the desulfurization system can operate stably, and the sulfur output can still meet the standard discharge.

benefits

1- control the export of so2 through polymer desulfurization synergist, so that high-sulfur ore raw materials can be used, which greatly reduces the procurement cost of iron ore raw materials.  

2-when the average sulfur content of the inlet is lower than 1700 mg/nm3, a circulating pump can be shut down, which can save a lot of electricity bills.
