System Overview
The Ionex system is an improved continuous ion exchange and continuous chromatography device, which has all the functions and advantages of ISEP and CSEP. The Ionex system adopts a special structure of rotary distribution valve (the ion exchange column does not rotate, only the valve rotates), which can completely replace other forms of continuous ion exchange and continuous chromatographic separation systems. It not only has good performance, easy installation and maintenance, but also saves more than 30% of investment and low maintenance costs. This system is widely used in the de exchange desalination of various sugar solutions in large starch sugar factories; Separation and purification of amino acids in biological fermentation plants; Chromatographic separation of multiple components in sugar solution, etc.

System advantages:
1. Low investment and operating costs: Compared with traditional fixed beds, pulse beds, simulated moving beds, and carousel systems, the consumption of water and chemicals can be reduced by 30-50%; The required resin can be reduced by 50-70%.
2. High product yield: The Ionex system adopts a continuous countercurrent operation with multiple columns in series, which has higher adsorption and resolution rates for active ingredients.
3. Good product quality: The Ionex system adopts a continuous countercurrent operation with multiple columns in series, which can achieve more effective and thorough separation of active ingredients and impurities. Therefore, the product quality will be better.
4. Less waste liquid discharge: The Ionex system, due to reducing the amount of water and chemicals used, will inevitably reduce pollution and emissions.
5. Higher product concentration: The Ionex system adopts a continuous countercurrent operation with multiple columns in series, and the countercurrent elution can obtain the highest concentration product eluent. Therefore, the processing cost and equipment investment of the post-processing process have been reduced.
6. Operation and control are simpler: Due to the continuous operation controlled by fully automatic computers, the working process is very stable and simple.
7. Flexible and convenient design transformation: The Ionex system allows for simultaneous implementation of multi-user functions under continuous operation conditions, thereby providing a high degree of flexibility for this system. The Ionex system can economically retrofit an existing fixed bed system. No matter where these fixed beds are located, as long as an Ionex ion exchanger is configured, the existing fixed bed system can operate according to the continuous countercurrent process of the Ionex system. In addition, the resin column of the Ionex system is different from the "carousel" type resin column of ISEP. It does not move, so it can be connected to external heating and cooling media, as well as other process pipelines as needed, with more flexible adaptability.

Application areas of Ionex system:
1. Sugar and Sweetener Category: The Ionex system also has many applications in the processing of sugars and sweeteners. For example, decolorization of sugar solution: glucose decolorization, sugarcane syrup decolorization. Sugar solution desalination: including fructose desalination, glucose desalination, etc. Separation and purification of different sugars: such as separation and purification of glucose and fructose, separation and purification of D-ribose and glucose, etc.
2. Pharmaceutical and biological fermentation industry: Ionex system is used for the purification and refinement of antibiotics and other drugs; Used for the separation and purification of amino acids and vitamin products, such as lysine, tryptophan, glutamic acid, phenylalanine, threonine, vitamin C, vitamin H, etc.
3. Industrial water treatment: The Ionex system is fully suitable for the water treatment industry, whether it is water treatment in power plants, chemical, pharmaceutical, paper and brewing industries. The Ionex system provides solutions for applications in various fields, such as complete desalination, condensate purification, hard water softening, deoxygenation, and removal of residual organic matter.
4. Wastewater treatment: The Ionex system can effectively treat industrial wastewater, such as removing small amounts of toxic substances such as heavy metals, chlorides, phenols, and other aromatic compounds; Gold, silver, nickel, and other metals can be recovered from wastewater.
5. Inorganic chemistry and organic chemistry industry. The Ionex system can be used for complex decomposition reactions in inorganic chemistry industry, ion catalyzed reactions in organic chemistry, separation and purification of active ingredients in chemical reaction solutions, as well as recovery of active and valuable ingredients in chemical reaction solutions.
