Green Industry "is a national high-tech enterprise that integrates" industry, academia, and research "collaborative innovation. It focuses on customized research and development of non-standard equipment and integrated development of advanced technology and process packages. Its core business focuses on process integration, energy conservation, comprehensive utilization of waste heat, and resource utilization. We rely on the profound academic background of research institutions such as Tianjin University and Hebei University of Technology to build a solid research and development foundation. We have accumulated more than 30 independent intellectual property patents and participated in the establishment of a research institute with waste heat energy conservation and resource utilization technology as the core specialty. The main service areas of the product cover industries such as petroleum, refining, and chemical engineering, especially in the field of fine chemicals, which has been deeply cultivated for many years.

Based on its own core research and development capabilities and technology, "Green Industry" has successfully developed and industrialized a series of key equipment, including process gas twin-screw compressor systems, twin-screw steam compressor heat pump systems, and twin-screw multiphase mixed flow rotor pump systems. These system solutions have been widely applied in industries such as petroleum, refining, chemical, environmental water treatment, and steel. They are the first tier suppliers of large petrochemical and chemical companies such as PetroChina, Sinopec, CNOOC, and Shenghong Petrochemical. Has successively been awarded the title of "Innovative Enterprise" by Tianjin City, as well as honorary qualifications such as "National High tech Enterprise" and "National Innovative Small and Medium sized Enterprise". At the same time, long-term industry university research cooperation relationships have been established with multiple research institutes such as the National Distillation Center of Tianjin University, the National Key Local Joint Laboratory of Hebei University of Technology, and the Desalination Institute of the Ministry of Natural Resources. At present, we have obtained more than 30 proprietary intellectual property patents and inventions, and have passed multiple authoritative system certifications. The R&D team is composed of more than 20 multi-disciplinary technical members led by 3 PhDs and 4 masters. A team that combines old, middle, and young members exhibits a vibrant and enterprising spirit, as well as youthful, professional, and skilled characteristics. The R&D team has developed multiple bromide and lithium salt crystal form control and high salt waste liquid resource chemical process packages, and multiple projects have achieved engineering industrialization. The application in the synthetic raw material pharmaceutical industry has achieved significant economic benefits for the production side.

After more than 20 years of development process full of challenges and opportunities, "Green Industry" has successfully transformed from a single equipment processing and manufacturing business to a comprehensive solution supply that integrates professional equipment research and process development. Nowadays, it has become an industry leader in the field of process integration, energy conservation, and comprehensive utilization of resources. In recent years, especially in the field of comprehensive utilization of waste heat resources to achieve energy conservation and emission reduction, the process packages and equipment combinations developed by "Green Industry" have been successfully applied to more than 30 projects. These application units have achieved significant economic and social benefits with the help of "green industry" technology and equipment, fully reflecting the value of our products and technology.

In the more than 20 years of ups and downs we have gone through, we have failed, succeeded, missed, and gained.

From 2003 to 2007, at the beginning of its establishment, we took the lead and started step by step from the most basic work, consolidating the foundation of technology and production;

From 2007 to 2013, we forged ahead with wind and rain, and the first rotor milling machine began processing rotors and designing and developing its own profile lines. We undertook the localization research and development task of a certain military project;

From 2013 to 2016, we have been deeply cultivating and accumulating resources, and have undertaken the development project of special multi-purpose mixed flow pumps by PetroChina. We have made significant breakthroughs in domestic oilfield applications, and the double helix multiphase mixed flow rotor pump system products have been officially standardized and quantified for production;

From 2016 to 2018, through transformation and innovation, we began to focus on research and development in the fields of process integration and waste heat resource recovery and reuse. In 2018, we developed and produced the first twin-screw steam compressor, which became a pioneer and explorer in the field of waste heat steam and secondary steam recovery and reuse. We pioneered the practical application of high-temperature and high-pressure twin-screw steam compressors in China. Becoming one of the domestic manufacturers of twin-screw steam compressors, the twin-screw steam compressor heat pump system has become the leading core product, and the research field of waste heat recovery and comprehensive utilization has become the company's main research and development direction for the next 20 years;

From 2019 to 2020, we went abroad with a new approach. Through the research and development of a dry oil-free twin-screw compressor unit with completely independent intellectual property rights technology, we successfully applied it to overseas markets. This is also a key equipment with completely independent intellectual property rights going abroad to serve the Central Asian market. The dry oil-free twin-screw compressor system has been finalized and started to be serialized and standardized, becoming the main manufacturer of gas compressors for small gas flow processes in China. Energy saving and emission reduction technology has been established as the core technology of the company;

2020- With diligence and determination, we strive for excellence and will continue to work hard on the path of progress!

The company currently has a production workshop of approximately 10000 square meters, equipped with multiple key core processing equipment such as imported and domestic screw rotor milling machines and rotor grinders. The rotor processing diameter can reach 650mm, and it is equipped with complete supporting processing and testing equipment, including large-scale rotor dynamic balancing instruments, rotor meshing instruments, rotor forming milling cutter detectors, coordinate measuring instruments, and four axis machining center CNC machines. At the same time, a comprehensive full process inspection system has been established, equipped with a mechanical and performance factory testing platform and a physical and chemical inspection laboratory. Before the product leaves the factory, it can be tested under simulated actual working conditions to ensure that the product quality and performance meet the design and on-site working conditions requirements.

In order to provide better, faster, and more professional services to users and the market, we have established a high-level and high-quality professional technical service team. We have set up a 24-hour successful user hotline, which covers pre-sales technical support, in sales technical services, and after-sales product upgrade and maintenance at multiple levels. We also develop asset efficiency improvement plans for customers, achieve intelligent supply chain guarantee, and provide guidance for customers' full scenario application empowerment. The service team is composed of multiple specialties such as electrical, instrumentation, mechanical, and complete sets, providing a "butler style" service throughout the entire process, focusing on solving on-site application and iterative upgrades for users. Our product service scope continues to expand. Currently, we have established offices in key customer areas in China, with professional and technical personnel stationed there. We have also extended our services to multiple countries and regions such as the Middle East, Central Asia, Russia, and Southeast Asia. By combining with local resources, we are able to provide convenient, fast, and comprehensive high-value services to overseas customers.
