Reactor vessel materials
Thread Content
The reaction temperature for the reaction H3PO4 + KCl = KH2PO4 + HCl↑ is 160–180 degrees, with a phosphoric acid concentration of 50% and a material ratio of 1.4:1. What material should be used for the reactor? The reactor is heated using heat transfer oil.
The operating temperature and stress must be provided.
The reaction is endothermic; heat transfer oil is used for heating to maintain the temperature of the material
Equipment used for producing potassium sulfate and hydrogen chloride gas from persulfuric acid and potassium chloride employs acid- and heat-resistant bricks. This process is called the Mannheim method, or Mannheim furnace; the reaction is endothermic, natural gas is used as fuel, the reaction temperature is kept above 200 degrees, while the temperature inside the furnace is maintained around 900 degrees.
:) The matrix is made of ordinary carbon steel, while the inner wall of the reactor is coated with a special anti-corrosion material. Our company already has a track record; feel free to contact me.
It is recommended to use the nickel-chromium-iron alloy series, specifically Alloy 20. If you need samples for testing, please contact me
