Alumina Grooved Ball.
Introduction of hydrogenation reaction chamber and SiO2 desulfurizer from 300 thousand tons synthetic ammonia installation in the 1970s; we started to adopt inert alumina balls as bedding course, the alumina content is generally about 40-60, so its not very strict to SiO2 content In the recent 20 years of using proof, it is vital importance for SiO2 content of alumina balls to run device; the results showed that SiO2 content of alumina ball would be occurred gasification under high temperature in hydrogenation reaction chamber and SiO2 desulfurizer, with the technical airflow, it would happen to transfer; finally tube attached to the wall and into gas compressor impeller, which result partial overheating from converter; when getting worse, its easy to occur tube explosion and also affect compressors normal working; we absorbed production experience from a large scale synthetic ammonia installation in order to protect converter and synthetic ammonia compressor. For that reason, our enterprise developed Al2O3 Grooved Ball with many research units, to solve the solid resistance, low-intensity perforation, lower pressure drop; and reduce wearing ration of catalyst, enlarge catalysts using time; so our products enjoy good reputation from many companies.
