GN Delivers 7 Units Decanter Centrifuge for Chemical Salt Dewatering

GN Separation is overjoyed to announce the recent dispatch of seven decanter centrifuges to a customer engaged in the chemical processing industry, with a particular focus on chemical salt production. These centrifuges are poised to assume a pivotal role in the continuous dewatering of a diverse range of inorganic chemical salts, a process that is highly dependent on efficient solid-liquid separation and unwavering reliability.20251203 Chemical Decanter Centrifuge

Chemical Salt Production Process and Equipment Significance

The production of chemical salts typically involves a series of steps, including crystallization, washing, and separation. The performance of the dewatering equipment during these stages has a direct and profound impact on the purity of the final product, the overall production efficiency, and the stability of the entire plant. GN’s decanter centrifuge solutions have been crafted with meticulous attention to detail, specifically designed to excel in these demanding conditions.

20251203 Crystal Salt Dewatering Centrifuge

Distinctive Challenges in Chemical Salt Dewatering

Dewatering chemical salts poses unique challenges for centrifuges due to the inherent properties of the materials involved. Salts such as sodium chloride, potassium chloride, sodium sulfate, and ammonium salts are known for their high density, sharp crystal edges, and corrosive chemical nature. These characteristics demand centrifuges that can withstand high levels of abrasion, resist corrosion caused by chloride-rich brine, and maintain stable operation under the intense conditions of high G-forces.

To overcome these challenges, GN’s chemical decanter centrifuges are constructed using duplex stainless steel or equivalent anti-corrosion materials for all key components that come into contact with the process fluid. Critical wear surfaces are further reinforced with tungsten carbide, ensuring exceptional long-term durability. This robust construction enables the equipment to operate continuously with minimal maintenance, which is an absolute necessity for chemical plants that operate around the clock.

Superior Separation Performance

During the dewatering process, the centrifuge is tasked with efficiently separating a large volume of crystal slurry while minimizing the moisture content of the discharged solids. Achieving the right level of dryness is not only crucial for enhancing product quality but also significantly reduces the energy consumption of downstream drying systems.

GN decanter centrifuges are equipped with high rotational speeds and optimized bowl designs that generate powerful centrifugal forces. This facilitates the rapid separation of crystals from the mother liquor. The stable and precisely controlled differential speed of the screw conveyor further enhances the dryness of the cake. Operators have the flexibility to fine-tune the performance based on variations in feed concentration or crystal size, ensuring consistent product quality even when production conditions are subject to fluctuations. This improved separation efficiency also leads to higher production throughput, enabling chemical plants to operate more efficiently and cut down on operational costs.

Cutting-Edge Control System for Enhanced Functionality

The functionality of the centrifuges is significantly enhanced when integrated with GN’s state-of-the-art control system. For the seven units delivered to the customer, GN has incorporated intelligent control technology that allows for real-time adjustments of bowl speed, differential speed, torque load, and feed rate. This high level of automation is of utmost importance in chemical salt operations, where changes in slurry density, crystal load, or temperature can have a significant impact on equipment efficiency.

The control system continuously monitors vibration, temperature, and other operating parameters, thereby enhancing operational safety and preventing potential failures. This ensures long-term stable operation, minimizing downtime and reducing maintenance costs.

GN’s Dedication to the Chemical Industry
