An overview,

China is a large country of coal consumption, coal after combustion produces a large number of SO2 and SO3, if not treated will cause great pollution to the environment, so it is necessary to desulfurize the flue gas generated after the combustion of coal-fired boilers.

The commonly used desulphurization process at present

1. Sodium-alkali double alkali desulfurization technology

2. Limestone/lime-gypsum desulfurization technology

Three, the main characteristics of sodium alkali double alkali method

Mature process, reliable operation, low investment.

Sodium absorption rate is high, liquid-gas ratio is low, desulfurization efficiency up to 95%.

Nakilli in the absorption solution can be reused with low operation cost after base replacement.

The flue gas humidity of the absorption tower is large and corrosive. The equipment, pipes and chimney after the absorption tower and the period need to be treated with anticorrosive.

Four, limestone/lime-gypsum desulfurization main characteristics

Mature process, reliable operation, widely used in industry.

The desulfurizer is cheap and abundant in resources, and the desulfurization efficiency can reach 95%.

Desulphurization by-products are available.

In the process of desulfurization, waste water is produced and can be discharged after treatment.

The flue gas humidity of the absorption tower is large, and the flue gas is corrosive. The equipment, pipes and chimney after the absorption tower and the period need to be treated with anticorrosive.
