Office Building of Weihai Puyi Ship Environmental Protection Technology Co., Ltd
The staff learned that Puyi Company was established in 2013 with a registered capital of 21 million yuan. It is a provincial-level high-tech enterprise with completely independent intellectual property rights, and its main products are ship exhaust gas desulfurization equipment. The product was officially launched in overseas markets in 2019, and has now achieved export earnings of over 50 million US dollars and export tax refunds of over 30 million US dollars. Both in terms of technology and revenue capability, it ranks among the top in the same industry nationwide.
Puyi Company always adheres to the business principle of people-oriented and integrity-based, and has gathered a group of industry elites. Not only does it have multiple doctoral and master's degree holders as its main technical backbone, but it has also established close strategic cooperation relationships with research institutes such as Dalian Maritime University, Ocean University of China, and Qingdao University.
The ship exhaust gas desulfurization equipment project is a project approved by the Ministry of Industry and Information Technology of China, jointly developed and implemented by Puyi Company and Dalian Maritime University. In 2016, the project was listed as a key construction project in Shandong Province; In 2017, it was listed as an excellent recommended product (technology) for energy conservation and environmental protection in transportation nationwide. In September of the same year, the project was accepted by an expert review team organized by the Ministry of Industry and Information Technology and the Ministry of Transport, and it was determined that the technology broke through the technical barriers set by developed countries, improved the ability of China's ship supporting equipment to comply with the International Maritime Organization's international conventions, and met the strictest emission standard of 0.1% m/m ship sulfur oxides stipulated in the International Maritime Convention. At present, the project has authorized more than 10 invention patents, more than 20 utility model patents, 4 international PCT patents, and 2 computer software copyrights, and has completed trademark registration in China, the United States, South Korea, Japan, the European Union, and Singapore.
In addition, Puyi Company's ship exhaust gas desulfurization equipment has obtained certification from China Classification Society, making it the first company in Asia to obtain a classification society recognition certificate in this field, filling the gap in China. The company has also obtained certification from BV in France, LR in the UK, ABS in the US, NK in Japan, DNV in Norway, and GL in Germany. The certification obtained by major shipping companies signifies that Puyi Company's products have obtained a passport to the international market.
In 2020, Puyi Company cooperated with Ocean University of China to carry out in-depth process transformation of its products. Compared with the desulfurization equipment of well-known European companies, the renovated equipment has reduced its volume by half, saved installation time by more than 60%, reduced equipment functional consumption by half, and reduced ship owner renovation costs by more than 50%. Moreover, Puyi is the first in the global industry to complete the integrated technology transformation of desulfurization and denitrification. The above advantages have enabled Puyi Company to firmly grasp the initiative of the global ship exhaust treatment market.

It is reported that the global market share of ship exhaust treatment is 200 billion US dollars. At present, Puyi products have been installed and operated in the fleets of the United States, the United Kingdom, Greece, India, Türkiye, Singapore, Japan, Taiwan, China and other countries and regions. Moreover, Puyi Company has signed a listing cooperation plan with securities companies, law firms, accounting firms, and investors, and the preparatory work is proceeding in an orderly manner.
In order to expand the environmental protection market space, Puyi Company has collaborated with renowned Canadian professors from Ocean University of China to carry out industrial cooperation on multiple new technologies, including HDH seawater desalination technology, efficient mass and heat transfer components, and efficient hydrogen removal catalysts.
The three key technologies of seawater desalination: ceramic wheel high-pressure energy recovery technology and equipment, high-pressure pumps, and long-term separation membrane materials are monopolized by the United States, Germany, and Japan, respectively. The new HDH seawater desalination technology is different from traditional membrane separation technology and is a disruptive new type of seawater desalination technology, mainly composed of humidification and dehumidification. In humidification, air and seawater are saturated in contact, and saturated air is dehumidified in the dehumidifier to produce condensed fresh water. This technology completely solves the bottleneck problem of membrane seawater desalination and achieves nationwide production of technology and equipment. This technology can be applied in marine chemical industry, chlor alkali industry, brine bromine extraction, and can also be used in islands, ports, ships, hotels, factories, brackish water, oil and gas fields, and industrial wastewater recycling. In 2020, the annual demand for small-scale seawater desalination equipment in the world was 2.2 billion US dollars, with an annual growth rate of 15%; In 2019, the total value of the global seawater desalination market reached around 19.1 billion US dollars, and HDH seawater desalination technology will be further optimized and scaled up to medium to large-scale equipment. Scaling up to medium to large-scale equipment for the large-scale recovery of large amounts of wastewater from white carbon black (SiO2) plants, with an additional demand of approximately 60 million yuan in the Chinese market.
Efficient mass and heat transfer components, as platform tower internals, are chips in the chemical industry. Specially designed for the new mass and heat transfer technology of water vapor two-phase, the efficiency of the components is 5-10 times higher than that of traditional water vapor two-phase mass transfer technology. The components have the advantages of corrosion and salt resistance, as well as reducing equipment costs and energy consumption, and reducing footprint. This component can be used in fields such as chemical, pharmaceutical, food, desulfurization, and wastewater treatment, with an annual market demand of over 50 billion yuan.
Efficient hydrogen removal catalyst, used to eliminate hydrogen gas in open or closed environments, especially hydrogen gas generated during battery charging and discharging. It can undergo hydrogen removal reaction at room temperature and has good hydrophobicity, toxicity resistance (CO, heavy metals, and other pollutants), and thermal stability. This catalyst has a wide range of applications and can be used in nuclear power plants, electric and hydrogen energy vehicles, chlor alkali industry, instruments and equipment for producing sodium hypochlorite disinfectant by electrolyzing salt water, disinfection and sterilization equipment for electrolyzing chlorine gas, nuclear submarines, large steam turbine generators, and removal of dissolved oxygen in water (water treatment for large hot water boilers).
The development of the above new technology projects requires a significant investment in research and development costs, as well as manpower and material resources. The company needs government assistance in the following areas:
1. The corresponding experiment requires the construction of an experimental equipment platform on a site that is relatively convenient for obtaining heat sources and seawater;
2. A convenient low-temperature waste heat (or solar energy) heat source is needed for supply;
3. Hope there is a salinity testing institution to provide salinity testing.
The company also hopes that relevant departments can provide policy assistance and financial support for research and development projects with special skills and advanced technologies.
