These technical reformations were made for(shift-de-sulfur) systems from aspects of process and equipment: Newly constructing 2400×24 000 mm de-sulfur tower,reforming regenerator;changing to use new type de-sulfur catalyst and de-sulfur pump.

is used for the gasification scrubber and the de-sulfur tower.

Experimental studies on flow fields,within internally circulating multistage spouted desulfurization towers,have been carried out by using a particle dynamic analyzer(PDA).

This article analyzed the reason of one quality accident in the construction of epoxy FRP for desulfurization tower.

The characteristics of the improved desulfurization tower are as following ∶filling the tower body by beds,filling and removing by time and quantity,replacing beds by slidding,and gas solid phase diffusing evenly.

This article describes key points for the modification of desulphurizing tower, regenerator and sulphur recovery in wet-type oxidizing desulphurizing system and desulphurizing catalyst choosing.

In a certain steel making plant,serious vibration appeared on the platform of desulfurizing tower when desulfurizing unit running.

Repair of Weld Flaw in the Desulfurizer 501-EA;

This paper analyzed the reasons of the invalidation of the corrosion protection measurements in the stainless steel desulfurizer,and relevant anti-corrosion measurements were introduced.
