Product Description

Mannheim Potassium Sulfate Project Overview

The Mannheim potassium sulfate production technology was developed by the Mannheim Verein in Germany in the 19th century. The core technology of this method is the Mannheim reaction furnace. With a century of development, improvements have been continuously made in terms of the materials and structural design of the furnace, as well as in energy conservation and environmental protection. The Mannheim process, currently employed by Hebei Aoliande Chemical Equipment Co., Ltd., is the most mature technology for producing potassium sulfate. It produces potassium sulfate of high quality and grade, with high potassium yield, while also producing high-quality by-product hydrochloric acid. The process used in this project is considered advanced technology.

  DCS Automatic Control System Used in the Project
To ensure safe, stable, efficient, and economical operation while reducing labor intensity, Hebei Aoliande Chemical Equipment Co., Ltd has integrated the DCS control system into the project's process design, in line with the characteristics of potassium sulfate production. This system accomplishes the tasks of monitoring, controlling, and managing key production process parameters such as temperature, pressure, flow rate, and liquid level. The entire process can be operated and controlled through a keyboard. The production process includes a logic control system and interlock protection to safely control hazardous materials in case of disoperation or abnormal conditions. Relevant electrical parameters and the operation/fault, shutdown of major electrical equipment are displayed on computer screens. The entire project achieves an automation level where monitoring, dispatching, and fire control management are unified and conducted from the control room via computers and large-screen televisions, reaching an operational modeProduction Process Adopted
The sulfuric acid flowing out from the lower outlet of the high-position tank is added to the reaction furnace through an electromagnetic flowmeter and an electric control valve. The flow rate is automatically adjusted by a valve set through the Distributed Control System (DCS), maintaining a partial overflow in the high-position tank to stabilize the pressure of sulfuric acid entering the electromagnetic flowmeter. The signal output by the electromagnetic flowmeter automatically adjusts the opening degree of the electric control valve to stabilize and adjust the amount of sulfuric acid added. Subsequently, sulfuric acid and potassium chloride react at a lower temperature in the reaction furnace to form potassium bisulfate. Potassium bisulfate reacts further with potassium chloride at a higher temperature (520-540°C) to produce potassium sulfate. The reaction product, potassium sulfate, is cooled, crushed, screened, and packaged to obtain the final product.
 Project Technology is Mature and Reliable
   The potassium sulfate unit of this project employs the domestically developed Mannheim process designed by Hebei Aoliande Chemical Equipment Co., Ltd. After fully absorbing and digesting advanced technologies, the company has continuously refined and conducted industrial trials, achieving an optimized upgrade of the entire set of equipment. Over the past decade, the company has installed and constructed dozens of Mannheim process potassium sulfate units both domestically and internationally. Their process technology has proven to be quite mature and reliable.
