K2SO4 Mannheim Process Potassium Sulfate Making Machine is well-known as there aretwo
kind of popular methods to be used to produce Potassium Sulfate Product, one is Doubledecomposition
method, the reaction is not good, the product quality should be improved.Another method is the
Mannheim furnace process, it is used widely, but there are somedifficulties occurred during the
production. We had made the necessary and importantimprovement and perfection on its production
equipment and production process ofMannheim furnace, to form a unique and perfect Potassium
Sulfate production technologynow, improve the construction and material of furnace to achieve even
heating, completereaction and low energy consumption. New material and technology is applied to the
partof hydrochloric acid absorption, thus absorption efficiency is enhanced and environmental issue is
also well resolved. Mannheim Process
The most common method of producing potassium sulfate is the Mannheim Process,which is the
reaction of potassium chloride with sulphuric acid at high temperatures. Theraw materials are poured
into the centre of a muffle furnace heated to above 600°CPotassium Sulfate is produced along with
hydrochloric acid in a two-step reaction viapotassium bisulphate. This method for creating SOP
accounts for 50% to 60% of globalsupply. The Mannheim Process is also the most expensive of the
processing techniquesdue to the high input costs associated with purchasing MOP and sulphuric acid.
This meansthat the final product costs about $500 per ton.The Mannheim process is an importantmethod
for the manufacture of hydrogen chloride and potassium sulfate from potassiumchloride (table salt) and
sulfuric acid in which case the K2SO4 is known as salt cake:2 KCI + H2SO4 - K2SO4 + 2 HCI Technical Advantage
1. Some key components of our potassium sulfate fertilizer equipment are made of specialmaterials which are corrosion resistant and durable. Hence, this fertilizer equipment also features long service life.
2. Waste recovery system to recycle hydrochloride acid (HCl) and meet environment requirements3. Adjusted original HCl absorption system, improved on the quality of the final product.4. lmproved the flue design in the furnace which can make full use of energy and saveenergy consumption.
5. Used PLC automatic control system to control manufacturing the products, adjust the ratioof feedstock, and saved the labor cost.
6. Adopt gas generator replacing other heating method.
7. Stable production and easy operation.
8. Large output& Low coal consumption
