Introduction to Liaoning Lan'en Environmental Protection Technology Co., Ltd

Liaoning Lan'en Environmental Protection Technology Co., Ltd. was established in 2012 and is a wholly-owned subsidiary of Liaoning Cologne Fine Chemical Co., Ltd. (Cologne Co., Ltd., stock code 300405). The company mainly produces extrusion and coating type denitrification catalysts, designs and manufactures SCR denitrification equipment and tail gas purification systems. The main products include power plant boiler flue gas denitration, diesel generator, various gas generator supporting denitration equipment, automobile, marine engine tail gas treatment, etc., and contracted petrochemical plants, mining and smelting kilns and other flue gas treatment projects. The company has established extensive industry university research cooperation with China National Academy of Building Materials, Institute of Chemistry of the Chinese Academy of Sciences, Dalian University of Technology, and China National Petroleum Corporation. The company has multiple patented technologies. The company's technical characteristics and leading advantages:

1、 Denitration catalysts have independent intellectual property rights

The company has established production facilities for 10000 cubic meters/year extruded honeycomb catalysts and 2500 cubic meters/year coated catalysts. The catalyst production process and formula have independent intellectual property rights. Adding rare earth elements to the catalyst components improves the catalyst activity and high-temperature aging resistance, and has good denitrification performance within the denitrification window temperature, expanding the range of product use.

2、 Independently designed and manufactured denitrification equipment

The company has a professional technical team in chemical, mechanical, and instrument control fields, which can independently research and develop, design, and manufacture denitrification equipment. The optimized combination of self-produced denitrification catalysts and denitrification equipment forms a complete industrial chain, which can be customized according to on-site conditions to provide users with thoughtful services.

3、 Introducing advanced catalyst evaluation equipment

In order to verify and evaluate the actual performance of the catalyst, the company invested in importing a flue gas treatment and catalyst evaluation device with DOC+DPF+SCR from H+H Company in Germany, using Siemens infrared gas analyzer, Siemens PLC, and precise fluid control system. Each batch of catalyst in the company needs to be evaluated for actual performance indicators in the evaluation device.

4、 The control system can achieve remote control

The SCR denitrification control system independently designed, programmed, and configured by the company can achieve local control, centralized control, remote control, and internet cloud control of smart devices such as mobile phones, and can achieve remote fault diagnosis, maintenance, and other functions.

5、 CFD simulation design for flue gas flow field

The flue gas flow field is designed using both numerical analysis and model experiments to achieve uniformity of the flue gas flow field, improve catalyst utilization, and ensure denitrification effect.

For many years, the company has been fully committed to environmental protection, focusing on the field of gas purification. The company adheres to the philosophy of "integrity in life, quality in products" and "selling is not the end, service is just the beginning", and is willing to wholeheartedly provide customers with high-quality products and services. The company will actively explore new fields, seek new development, achieve new breakthroughs, seek truth and pragmatism, and comprehensively build a harmonious and efficient enterprise.

Lan'en Environmental Protection is willing to work together with you to create a beautiful ecological environment with blue sky and white clouds in our motherland.
