ITMA 2015: Innovative solutions for caustic recovery

Körting Hannover AG is a global market leader of Caustic Recovery Plants (CRP) and will showcase its innovative solutions at ITMA 2015. Its technology efficiently cleans lye that is highly concentrated and has been soiled when yarn-dyeing products and denim items. The process is already creating quite a stir.

Weak lye, strong lye before cleaning, strong lyeafter cleaning


For years, the textile industry has relied on Körting Caustic Recovery Plants (CRP) to guarantee sustainable production. With the help of Körting Caustic Recovery Plants, the waste weak lye produced during the mercerisation process can be transformed into concentrated caustic soda and used again. Lye cleaning systems with peroxide have had a good track record for years and years. The Caustic Recovery Plant treats the concentrated lye based on this process. To reuse the lye without any loss in quality in the mercerisation process, cleaning is vital, particularly in the case of yarn-dyed products and denim. By developing the process over a long period of time and constantly listening to customers’ requirements, Körting can offer a sophisticated and innovative solution that is popular the world over.

The benefits of Körting Caustic Recovery Plants (CRP)

Since 1956, Körting Hannover AG has installed and commissioned more than 200 Ccaustic Recovery Plants in over 50 countries. The plants offer a number of advantages. The return on investment is under a year and the plants also significantly boost the sustainability of the production process. In the past, disposing of the weak lye produced during mercerisation was complex. Nowadays it can be recovered and reused with Körting technology. The mercerisation plant no longer produces any alkaline waste water. Due to the company’s developments and experience with waste gas cleaning, all Körting Caustic Recovery Plants have tried-and-tested swirl droplet separators. These ensure that the vapour condensate (distillate) has a low pH value. Therefore, the vapour condensate can be reused in production and doesn’t have to be treated like waste water. The client’s eco footprint is improved and sustainability improved because fewer chemicals are needed to treat the waste water.

High-performance Körting ejectors for waste water aeration

Körting ejectors for waste water aeration meet the most demanding of requirements when it comes to efficient and reliable oxygen transfer systems. Sewage plant operators worldwide value the maintenance-free machinery and superb use of oxygen. The ejectors ensure that the waste water is constantly circulated. As a result, they operate much more efficiently than other aeration systems. The ejectors ensure the oxygen is transferred in the best possible way and that the content of the tank intermixes. The presence of a large amount of solid matter is no problem. The ejector technology is ideally suited for neutralising alkaline or very alkaline waste water with waste boiler gases containing carbon dioxide. Today, many operators of industrial sewage plants count on waste water aeration with Körting ejectors. These Körting solutions are also the number one choice in the textile industry when a cost-effective and efficient oxygen transfer system is needed.

Körting at ITMA 2015

ITMA 2015 will take place in Milan from 12 to 19 November 2015. It’s often called the Olympics of the textile industry, not only because it takes place every four years, but also because it’s the world’s biggest trade show for the textile industry. Körting Hannover AG will be there in hall 10 and on booth A103. The showcase will include sought-after solutions for caustic recovery and lye cleaning. Based on decades of experience with a whole host of projects, the trade show is the best opportunity to discuss customised and effective solutions with Körting experts.
