Producers of soda ash and technical salts are looking for ways to meet the high demand for their product, while at the same time meeting the demand for greener, more efficient and sustainable production. The production processes and means of transportation are being reviewed and renewed.
ANDRITZ supports this with research and pilot plant tests executed by knowledgeable and highly skilled process engineers.
As many of the soda ash and technical salt manufacturing processes involve solidification, thickening, dewatering, drying, calcination and cooling, ANDRITZ separation specialists are working in close collaboration with the industry to develop green production plants that meet consumer demands.
Our pilot plants around the world determine and test next-gen dewatering and drying solutions. Whether the customer is a start-up with a great idea for creating new applications or upcycling waste, or a known partner with a need to improve efficiency in an existing process, our team is there to support them. All backed up by modern automation solutions.
Whether you produce ammonium chloride, ammonium sulfate, calcium chloride, carbonate sludge, crude and refined sodium bicarbonate, dense soda ash, ferrous sulfate, potassium sulfate, sodium chloride, sodium sulfate or other salts, we have the in-depth process knowledge and a range of technologies to help make your operation successful.
ANDRITZ specialists have gained an extensive knowledge of solidification, thickening, dewatering, drying, calcination and cooling through multiple stand-alone and turn-key batch and bulk projects at various (multinational) production plants of soda ash and technical salt manufacturers. They know that each type of raw material requires a different production method to reach the desired end product. With endless installations worldwide, ANDRITZ has a proven track record of excellent results with very little downtime.
