Part I : R & D context Digestion process control is paramount in alumina refining Performance of control valves directly affects production In digestion electric angle type needle control valves are installed between flash tanks Harsh operating conditions: Mixed Solid-Liquid-Gas medium Abrasive solids in the slurry cause erosion High temperature and pressure Large pressure drops Part 2 Tube digestion process High temperature, pressure tube digestion technology is widely used for alumina refining In the tube, turbulence of bauxite slurry flow allows for efficient heat transfer and short digestion time Hard to dissolve diasporic ba uxite requires 9 pre-heating stages followed by 8 flashing stages before discharging in the dilution tank . Valve operating conditions Installation position: between flash tanks in pressure digestion syst...

Coal water slurry gasification is one of the world’s most advanced technology on the coal gasification, which is widely used in the coal chemical enterprise. The working condition of the coal water slurry is very hard, as well as valve is in the key process of the pipeline, thus the valve selection becomes a headache problem for many valve procurement engineer. Coal water slurry is a mixture of liquid and solid powder. When the medium flow into the circular type orifice, the flow speed is very high. The valve of this system faces the following problems : 1.The coal water slurry reaches a very high flow rate in the valve orifice, at the same time the coal slurry has a certain degree of hardness, so the erosion damage to the valve is quite serious. 2. The coal slurry is easy to be deposited to block the valve cavity, so the valve flow channel is required to be clear without dead space, the coal slurry particle is quite fine, is very easy to penetrate into the valve ball gap and ma...

Since the distinctive characteristics of soda industry, all soda producers make every effort to apply valves to their process systems. They have to cope with not only internal and external leakages of valves, but also the troubles with scaring, blocking, crystallizing and eroding. With their cooperation for many years on a case by case basis and by way of continuous improvement. Henan Quanshun Flow Control S&T Co.,ltd has successfully developed the 4th generation of special eccentric valves for soda ash producers, meeting soda ash producers, demands for normal production and management. In view of characteristics and demands of soda enterprises and through continuous improvements. Henan Quanshun finally developed such products as soda specific valve and control valve which could meet the on-site management requirement of soda producers. Soda Specific Valves (Worm Operated, Pneumatic Operated and Motor Operated Series ) (Block type) “C” type ball valve for making sod...
