Predictions Catalytic Distillation Column Start-up Processes Via Artificial Neural Network;

Causes of pressure fluctuation of stabilizer in gasoline hydrodesulphurization unit in start-up stage

The start-up scheme of JN60-6 type large-volume coke oven in Benxi Iron & Steel Group Co.

The result of pilot plant test in a 60 L commercial unit shows that the catalyst has a short start up time and there is no exothermic phenomenon during the starting up process.

A new method for sulfuric acid alkylation unit start up has been successfully adopted under the condition of inadequate iso butane concentration, so the requirement on iso butane purity for sulfuric acid alkylation unit start up has been greatly reduced and the unit has been smoothly started up.

Techno-economical analysis and comparison of oxidation catalyst and sulfurization catalyst have been carried out based on the process technology and practical start up of two catalytic reforming units.

Improvements in Safe Startup of FCC Plants;

Presents the startup,operation and calibration results of twice full load operation of the newly-built 1.

The result of its application in the first startup showed that, this new method i.

At present,several technological processes of producing ammonium molybdate,typical several methods of rare-earth doping molybdenum products and recent development of rare-earth elements doping molybdenum powder,molybdenum wire and molybdenum sheet and blooming process of molybdenum processing are elaborated respectively.
