The past decade has been a period of rapid development for China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which in turn has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. Everyone is welcome to share their thoughts and insights; let’s cheer for Made in China and support the development of chemical processing equipment! *********************************** On June 5, 2018, at 9:17 a.m., on Yushan Island in Zhoushan, Zhejiang – the location where China’s eastern golden coastline meets the Yangtze River’s vital waterway – the four largest complete air separation cryogenic units in China, designed and manufactured by Hangyang for Zhejiang Petrochemical’s integrated refining and chemical processing project, reached the crucial moment when the last one of them was lifted into place. As the world’s largest 4,000-ton crawler crane steadily lifted the top of the cold storage container, with the assistance of two tail-grip cranes, this “giant dragon” slowly raised its head. This is the largest-scale hoisting operation for an integrated air separation unit in China to date. To ensure the smooth lifting of the cryogenic tank, Hangyang organized relevant personnel to hold special meetings, conducted numerous calculations and optimizations regarding the lifting points, and arranged the installation of the lifting equipment in an appropriate manner, thereby effectively reducing the risks associated with the lifting operation. As the top of the cold box gradually rose, at 10:25 the cold box was fully erected and the auxiliary crane disengaged. The lifting of the cryogenic box entered the translation phase; after nearly two hours, the box was lifted into place at 11:20, and the reinforcement of its bottom was completed along with the disengagement of the main crane by 8:00 a.m. on the 6th. It is reported that the first three main cryogenic tank units were lifted into place on May 4, 14, and 28, 2018, respectively. With this, all four cryogenic tanks have now been installed, and the lifting operations were completed successfully. Zhejiang Petrochemical’s fourth set of 83,000 m3/h air separation units represents the largest contract order for Hangyang since it won the contract for six hundred-thousand cubic meter air separation units for Shenhua Ningxia Coal. This deal breaks the monopoly held by foreign companies in the supply of large-scale air separation equipment for integrated refining and chemical projects, highlighting Hangyang’s advantages in terms of technology, manufacturing, quality, and service for such equipment, and demonstrating the leading position of \"Made in Zhejiang\" in the air separation industry. During the implementation process, new problems arose one after another. “Under the entirely new design concept for horizontal and vertical installation in fully equipped refrigerated containers, multiple aspects of optimization and low-temperature safety of the base have become new challenges – issues that were not problems in the past. In the production of these projects, Hangyang utilizes the \"Zhejiang Manufacturing\" standards. It has innovatively introduced the concept of a \"borderless factory,\" extending the location of cold box production to \"port factories.\" This approach not only prevents interference from external factors but also facilitates product transportation, thereby greatly improving efficiency. “This entirely new production model opens up new possibilities for future manufacturing projects of large-scale air separation equipment in areas with poor transportation access and harsh environments, further highlighting Hangyang’s manufacturing capabilities in this field. This means that Hangyang is capable of meeting the new requirements for the manufacturing of large-scale air separation equipment both domestically and internationally, laying a solid foundation for the future export of such equipment. ”
80,000 m3/h and 100,000 m3/h air separation capacities represent first-class levels on par with the world’s best.
By comparing itself with internationally advanced companies over the past few years, it has at least reached the first tier in terms of scale; a considerable amount of complete air separation equipment has been exported

It’s estimated that the volume of exports won’t be large; many of those Japanese companies’ domestic chemical production facilities are already quite small in scale. If I gave them such a large air separation unit, I’m worried that the low oxygen levels in those small areas could result, and then they would again speak ill of China.
It is estimated that North America and Europe will need to install a new round of LNG liquefaction and gasification facilities. Oil merchants in the Land of the Free made huge profits.
In Hangzhou, besides Hangyang, there is another company that also produces cryogenic tanks
From 2002 to 2019, Hangyang advanced from having air separation equipment in the 30,000 to 120,000 capacity range to possessing equipment in that higher range, evolving from a follower of the world’s most advanced air separation technologies to a peer and even a leader in this field. Today, oxygen separation towers manufactured by Hangyang have been erected in over 40 countries and regions around the world. In 2009, Hangyang exported large-scale air separation equipment to a German company, thus breaking into the market of this industry’s birthplace in the world. In recent years, Hangyang has also taken on air separation equipment projects along the Belt and Road in countries such as Malaysia and the Middle East. Today, Hangyang’s air separation equipment not only has the highest production volume in the world but also features technology at the global leading level, serving as a testament to the excellence of China’s equipment manufacturing industry. Leveraging its technical expertise and brand strengths in air separation equipment, and as a model in the high-end equipment manufacturing sector, Hangyang was featured in CCTV’s documentary series \"Major National Equipment\" in 2018.
