Liquid ammonia is a basic raw material in agriculture, basic chemical industry and high-end manufacturing, among which 7N ultra-high purity electronic grade ammonia is an irreplaceable core specialty gas for global semiconductor, photovoltaic and Mini/Micro LED display industries, and the market scale continues to grow at a high speed. 2.8 billion USD of the global electronic grade ammonia market will be reached by 2025, and it is expected to increase to 4.6 billion USD by 2033, with the demand for semiconductor chip manufacturing accounting for nearly half of the demand share. Semiconductor chip manufacturing accounted for nearly half of the demand share; advanced 3-7nm process, silicon carbide photovoltaic cells on the purity of ammonia required to reach 7N (99.99999%), metal impurities control at the level of ppb, the threshold of purification technology is extremely high, the global market for a long time by a small number of overseas chemical enterprises dominated the stability of the regional supply chain, the procurement cost of long-term constraints on the development of midstream and downstream manufacturing enterprises. The stability of regional supply chain and purchasing cost have long constrained the development of middle and downstream manufacturing enterprises.
Fullcryo’s self-developed multi-stage low-temperature distillation + deep adsorption coupling purification technology has successfully realized the stable mass production of 10,000 tons of 7N electronic-grade ammonia in Tangshan, which completely fills the blank of high-end electronic gas industry in Hebei seaport area, and directly breaks the long-standing monopoly of foreign enterprises on the high-purity ammonia market. Relying on the stable supply of local production capacity, wafer fabs and photovoltaic cell enterprises in North China and Bohai Rim can significantly shorten the transportation cycle of raw materials, reduce cross-border purchasing and warehousing costs, and avoid the risk of supply cuts caused by fluctuations in the international supply chain.
From the dimension of industrial support, the project makes up for the key short board of the regional chemical – new energy – semiconductor industry chain, improves the supporting capacity of local high-end manufacturing raw materials, and helps the region to build an electronic special gas, green hydrogen, LNG integrated industry cluster; looking at the world, Fullcryo high-purity ammonia complete set of processes can be exported to Southeast Asia, the Middle East, Europe, and other coking-rich regions.
