From 3 to 5,December,2020,2020China Electronic Material Industry Technology Development ConferenceCo-sponsored by China Electronic Material Industry Association,No. 5 Research Institute of Electronics of the Ministry of Industry and Information Technology, Guangzhou Industry and Information Technology Bureau, and the People’s Government of Huangpu District, Guangzhou was successfully held in Huangpu District, Guangzhou.Shanghai GenTech Co., Ltd. (hereinafter referred to as "GenTech") participated in the conference and delivered a speech entitledHelium Recovery in the Pan-Semiconductor Field. Centering onthe theme of "newmaterials,newapplications andnewchallenges - collaborativeinnovationwinning development", this conference focused ondiscussions about5G new applications, integrated circuits, noveldisplays, high-end components and other key industry chainneeds and othermultiple dimensions such as national policies, industry status, technological innovation, facedcore issues, and future development directions, leading development of electronic materials and other topics, exchanging the most cutting-edge and leading new technologies, new developments and new applications in the current electronic material field,studyingnew opportunities and new challenges facing the industry.

Ms. Shi Yun, general manager of GenTech Electronic Material Development Departmentmentioned in her speech that heat transfer medium in optical fiber sintering process and heliumappliedfor cooling in drawing process are currently emptied directly or emptied after entering the exhaust gas treatment system, resulting in helium resource waste.Chinais helium insufficient, mainly relyingonheliumimport, self-sufficiency is less than 1%.China optical fiber manufacturing capacity accounts for more than 50% of the world.Heliumrecovery and recycling is of great significance to resource conservation and supply guarantee. Taking the optical fiber industryforexample, the helium recycling system developed by GenTechappliesadvanced separation and purification technology to recover and purify helium in the tail gas of the preform process, recyclingit.

At present, GenTech helium recovery cycle solution has been verified by multiplecustomers at home and abroad.Purity of recovered helium reaches 99.999% andheliumrecovery rate reaches 70%.Purified helium is directly reused in preform synthesis process, significantly reducing costs of raw materials for customers, achievingefficient reuse of resources. GenTech has been deeply involved in the fields of high-purity gas and chemical transportation and electronic special gas purification for more than 20 years. Based on process medium supply system, it has formed6 areas including synthesis and separation and purification of high-purity materials, regeneration and recycling of key process materials. core technologies, extendingto the front and back ends of the industrial chain, achieving  coordinated development of4 major businesses from high-purity electronic gas materials, high-purity process media distribution and supply systems, MRO to regenerative recycling solutions.
