Job requirements: Master’s degree or above, with in-depth knowledge of polymer material synthesis and pressure swing adsorption. Contact person’s mobile number: 13195888080 (General Manager Wang Hai) Company profile: Dalian Hai’ao Membrane Technology Co., Ltd. was established in December 2009, with a registered capital of 30 million RMB. The company puts people first and technology at the forefront. It focuses on the research and promotion of membrane technology applications to address issues related to energy conservation, emission reduction, and other efficiency and environmental protection concerns for enterprises. With extensive engineering experience, it has independently developed a membrane separation process design software that integrates with internationally renowned chemical engineering software such as ASPEN, HYSYS, and PROII. This enables the company to provide clients with not only top-tier industrial equipment but also optimal technical solutions, thereby achieving an ideal balance among initial investment, ongoing maintenance costs, and energy consumption. While continuously improving established membrane separation processes, Dalian Hai’ao Membrane Technology Co., Ltd. is also actively exploring new areas of application for membrane technology. It can provide experimental equipment for various enterprises and users, help develop new processes, and determine design parameters and process packages. Dalian Hai’ao Membrane Technology Co., Ltd. always recommends to its customers products of reliable quality and superior performance, ensuring no worries after use. For gas separation membranes, the Prism membranes produced by PermaPure in the USA are used; for organic vapor membranes, products from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, are utilized. Dalian Hai’ao Membrane Technology Co., Ltd. is a company specializing in the integrated application of membrane technologies. It has expertise in various types of membranes, including gas separation membranes and liquid separation membranes. Among the gas separation membranes, there are hydrogen separation membranes, organic vapor separation membranes, CO2 separation membranes, dehumidification membranes, oxygen-enrichment membranes, nitrogen-enrichment membranes, etc. All these separation membranes hold great potential for application in the petrochemical industry, where they can help petrochemical plants address numerous environmental protection and energy conservation challenges. At the same time, integrating membrane separation technology with other separation technologies to achieve optimal separation results is also a key focus of our company’s technological development. Through such integration, we aim to minimize both the initial investment and ongoing operating costs of equipment, thereby enhancing the economic viability of the technology. This makes it possible to implement projects that were previously deemed uneconomical; for instance, in the case of dry gas from catalytic cracking—a gas with a relatively low hydrogen concentration—neither membrane separation nor other separation methods alone can meet economic requirements. However, by combining membrane technology with pressure swing adsorption and further refining the separated products, excellent economic results can be achieved, bringing substantial benefits to enterprises. On this topic, we have collaborated with Xinghai Petrochemical to jointly apply for financial support from Jiangsu Province’s science and technology fund. Dalian Hai’ao Membrane Technology Co., Ltd. is a young and dynamic high-tech company that is eager to welcome ambitious talents who wish to contribute to the field of gas separation and production, as well as to efforts aimed at energy conservation, emission reduction, and improved efficiency in our country. Gas separation membrane technology is regarded as a 21st-century technology (while electronic technology is considered a 20th-century technology). In China, its development got off to a relatively early start. In 1978, the world’s first industrial application of gas membrane separation technology was realized in the United States; in 1987, China also achieved the industrialization of this technology. The time difference between the two is less than 10 years, and China became the second country to master this technology**. However, China’s gas membrane separation technology is currently far behind the world’s advanced levels; there are already several countries that have mastered this technology and are ahead of China. The main reason why membrane technology in our country lags behind the world’s advanced level is that other advanced countries have already mastered the polyimide membrane manufacturing process and industrialized it. At present, our country can only produce polysulfone gas separation membranes. Compared to polyimide gas separation membranes, polysulfone gas separation membranes exhibit significantly different performance, which limits their areas of application greatly. Currently, there are **not many countries in the world that have achieved industrialization of the polyimide film industry; only the United States, France, Japan, and Germany do. In our country, three researchers have successfully synthesized polyimide gas separation membranes in the laboratory; unfortunately, they have not been able to achieve industrial production. Although our country’s film-making technology lags behind the world’s advanced levels, its promotion of membrane technology is far ahead of the rest of the world. The application of gas membrane separation technology in China has been the most successful, and it represents a market that major film-producing countries around the world are competing fiercely for. Since 2003, when Wang Hai first applied gas membrane separation technology to hydrogen recovery in oil refineries (using imported polyimide membranes; this application involves low pressure differences and stringent separation requirements), it put an end to the situation where gas separation membranes could only be used in the purge gas from ammonia synthesis plants (which involve high pressure differences and relatively relaxed separation requirements). Since then, polysulfone membranes in China have gradually faded from the scene. Thanks to the promotion of membrane technology over the past 20 years, foreign membranes now account for over 95% of the market share in China. At present, gas membrane separation technology is widely used in various industries in China, but the vast majority of membranes in use are imported, resulting in a serious bottleneck issue. It is urgent for China to resolve this problem and achieve the localization of high-performance gas separation membranes. As a scarce non-renewable resource, helium is primarily found in natural gas. Our country is helium-poor; due to the very low helium content in natural gas, as well as the high costs associated with extraction techniques, the country relies almost entirely on imports for helium. As a technology-oriented enterprise specializing in the research, development, and promotion of helium extraction technology using membrane processes at ambient temperature, Dalian Hai’ao Membrane Technology Co., Ltd. provided technical support for Ruihua Energy’s project on helium extraction from LNG off-gas (BOG). To safeguard the strategic security baseline for helium, innovation in BOG helium extraction processes is essential. Traditional helium extraction uses helium-containing natural gas as raw material, involves repeated liquefaction and fractionation, followed by adsorption purification using activated carbon, to ultimately obtain pure helium. In addition, there are also air separation and hydrogen liquefaction methods for extracting helium. However, traditional methods generally have drawbacks such as high investment and high energy consumption. Breaking through numerous “barriers” to protect the country’s limited helium resources while enhancing the economic viability of helium production has been a topic that Dalian Hai’ao Membrane Technology Co., Ltd. has pondered over repeatedly. As professional researchers in the energy sector who are committed to ensuring safety through the use of helium and eager to promote the development of helium extraction industries in China, the technical team at Dalian Hai’ao Membrane Technology Co., Ltd. made numerous attempts and eventually succeeded in developing the \"room-temperature membrane-based helium extraction technology.\" This led to the formulation of a plan for the \"comprehensive utilization of helium extracted from LNG plant exhaust gases.\" “The “Comprehensive Utilization Project for Helium Recovery from LNG Plant Exhaust Gases” focuses on constructing advanced and efficient helium production facilities along with the corresponding filling and storage infrastructure. This project uses BOG produced by Ruihua Energy’s LNG plant as raw material, and employs a series of advanced processes such as membrane separation to purify the helium component in the gas; the purity of the resulting product can reach over 99.999%. The technology for extracting helium at room temperature features low investment costs, low energy consumption, small space requirements, modular design for flexibility, and high reliability. From the perspective of strategic resource reserves, the \"Comprehensive Utilization Project for Helium Extraction at Room Temperature\" holds great strategic significance. The project utilizes a domestically developed \"room-temperature membrane helium extraction technology,\" which not only overcomes the drawbacks of traditional helium extraction methods, such as high investment costs and high energy consumption, but also helps to address the issue of China’s heavy reliance on imported helium. To a certain extent, this technology meets market demands; currently, it has been subject to **patent application**. The company plans to establish a Helium Research Institute, which will focus on optimizing the room-temperature membrane-based helium extraction process and equipment, as well as researching and developing key equipment—namely, high-performance polyimide gas separation membranes—thereby reducing its reliance on imported core equipment. At the same time, for all-round technology promotion, marketing personnel are needed. The company has a branch in Xi’an.
