Mannheim Process Potassium Sulphate Making Equipment

It is well-known as there are two kind of popular methods to be used to produce Potassium Sulfate Product, one is Double decomposition 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 some difficulties occurred during the production. We had made the necessary and important improvement and perfection on its production equipment and production process of Mannheim furnace, to form a unique and perfect Potassium Sulfate production technology now, improve the construction and material of furnace to achieve even heating, complete reaction and low energy consumption. New material and technology is applied to the part of hydrochloric absorption, thus absorption efficiency is enhanced and environmental issue is also well resolved.

Mannheim Process

The most common method of producing potassium sulphate is the Mannheim Process, which is the reaction of potassium chloride with sulphuric at high temperatures. The raw materials are poured into the centre of a muffle furnace heated to above 600ºC.

Potassium sulphate is produced along with hydrochloric in a two-step reaction via potassium bisulphate. This method for creating SOP accounts for 50% to 60% of global supply. The Mannheim Process is also the most expensive of the processing techniques due to the high input costs associated with purchasing MOP and sulphuric. This means that the final product costs about $500 per ton.

The Mannheim process is an important method for the manufacture of hydrogen chloride and potassium sulfate from potassium chloride (table salt) and sulfuric in which case the K2SO4 is known as salt cake: 2 KCl + H2SO4 → K2SO4 + 2 HCl   

Technical advantage

1. Some key components of our potassium sulfate fertilizer equipment are made of special materials which are corrosion resistant and durable. Hence, this fertilizer equipment also features long service life.

2. Waste recovery system to recycle hydrochloride (HCl) and meet environment requirements

3. Adjusted original HCl absorption system, improved on the quality of the final product.

4. Improved the flue design in the furnace which can make full use of energy and save energy consumption.

5. Used PLC automatic control system to control manufacturing the products, adjust the ratio of 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.

Overall operation advantage

1. Professional logistic team, rich experience on container transportation and bulk transport.

2. Powerful customs clearance ability.

3. Complete database of cargoes, especially detailed information for set of equipment suppliers and shipping.

4. Strong ability to integrate the export and import documents. Such as customs clearance documents, C/O, and embassy certification documents, etc.
