The characteristics of gas separation export trade
air separation plant exports have developed from the original export of only small and medium-sized air separation plant to a full range of products, as large as 120,000 m³/h air separation unit , including foreign-funded enterprises have 150,000 m³/h air separation plant exports of product varieties from only air separation plant, expanded to pure nitrogen air separation plant, liquid equipment, natural gas liquefaction devices, variable pressure adsorption devices (especially variable pressure adsorption hydrogen device water electrolysis hydrogen production) Equipment, cryogenic storage tanks and other full range of products: from the number of small exports accounted for the majority of products, but the value of the low, on the other hand, the competitiveness of the international market in terms of domestic enterprises brand from the export enterprises, set up in China manufacturing base of foreign enterprises to overseas there is still a gap between the export volume of large quantities such as French liquid air and Linde: export product turnover, the export value of foreign enterprises in China accounted for air separation plant. The export value of domestic products on the one hand is not as high as that of foreign enterprises on the other hand. The export countries have developed from the original Southeast Asian countries only to many countries in Asia, and also to Eastern Europe, Russia and Western developed countries. From the point of view of export content, including not only complete sets of equipment, but also air compressors oxygen compressors cryogenic expanders special cryogenic valves / molecular switching valve / high-pressure oxygen valve plate fin heat exchanger cryogenic vessels and other key supporting parts of the machine from the export mode, has been from the simple export of equipment to overseas projects of general contracting and even individual gas investment projects in operation. From the point of view of the quality of export users, also gradually from some small customers to the development of internationally renowned companies and even industry giants, such as Hangxiao cooperation of overseas users in many of these countries is the metallurgy, gas, steel and chemical industry, fertilizer, glass and other industry giants.
With the increase in the number of China's exports of equipment running, the increase in the mouth of the air separation unit made in China, the proportion of the market will further increase, but due to the number of large projects abroad, so the number of exports of large-scale air separation unit is relatively limited.
