白酒氧化系统

The purpose of white liquor oxidation is to improve the Na/S balance of the Kraft process by replacing make-up caustic with internally generated alkali.

Valmet提供两种经过良好的经过熟练的高效替代品,一种用于生产部分氧化白酒的空气氧化系统,以及用于生产完全氧化白酒的氧化氧化和氧脱氨酸。氧化白液也可用于许多气体洗涤应用。

基于空气的系统

With the air-based system, oxidation takes place in a multi-stage reactor. The air is fed to the reactors from a rotary air blower. Primarily, partial oxidation takes place and the sulfide is converted into thiosulfate. The cost of operation is low as atmospheric air is used to supply the required oxygen. This process is highly suitable if the main target is the elimination of sulfide.

硫化物转化为硫代硫酸盐:97-98%。

Oxygen based system

In the oxygen based process oxidation is carried out in pressurized loop reactors. High efficiency jet mixers secure that the liquid phase is saturated with oxygen at all times.

该技术为硫化硫化物转化为硫酸酯的高反应速率提供了良好的环境 - 惰性化合物,其不会在下游工艺中进一步氧化。

Sulfide conversion into thiosulfate: 98–99 %
硫化物转化成硫酸盐:上调60%
