In August 2021, PKU Pioneer won the bid for the ZO-6666/90 VPSA oxygen production project of Tianneng Battery Group Co., Ltd. (hereinafter referred to as “Tianneng Group”). In November this year, PKU Pioneer has completed the process design for the VPSA oxygen plant project, and the civil works have entered the comprehensive construction stage.

Having established a diversified industrial structure comprising of new energy lithium battery, intelligent energy, cyclic utilization of resources etc., Tianneng Group is mainly engaged in the production of green power batteries. PKU Pioneer has already reached cooperation with Tianneng Group for the first time several years ago. In Dec. 2018, Anhui Tianchang Metal Materials Co., Ltd, a subordinate company of Tianneng Group, commenced the construction of its technical transformation and expansion project of recycled refined lead with an annual output of 200,000 tons. PKU Pioneer built a set of VPSA oxygen equipment with a capacity of 6500Nm3/h for the project, which was put into operation in 2019. Oxygen produced was stably transferred to the oxygen-rich side-blown smelting furnace, significantly reducing the oxygen usage cost.

In order to respond to what the country requires to implement the pollution prevention and comprehensive utilization of waste storage batteries, in August 2021, combining with its enterprise development plan, Tianneng Group commenced the construction of the comprehensive harmless utilization project of waste lead storage batteries (containing lead waste) with an annual processing capacity of 250,000 tons at its Jiangsu Tianneng Shuyang base. By the official bidding held by Tianneng Group headquarters, combining with the facts of good working conditions, smooth operation and remarkable energy saving and consumption reduction benefits made by the phaseⅠVPSA oxygen unit built by PKU Pioneer, the two parties agreed to cooperate for the second time and successfully signed the contract for the supply of VPSA oxygen production plant (6666Nm3/h) to support this project. Similar to the technical renovation and expansion project of reclaimed refined lead at Anhui Tianchang Fuyang base with an annual production capacity of 200,000 tons, this project applies alike the oxygen-rich side-blowing furnace, acid production from flue gas and other advanced processes, equipment and technologies, being equipped with an integrated recovery system to recycle refining slag, anode mud, lead-containing waste, lead slag, etc., and strengthening the automatic control at the same time. Its products are mainly supplied to Tianneng Group and other lead storage battery manufacturers to meet their production demands.

In recent years, PKU Pioneer has built approximate 30 sets of VPSA oxygen systems for reclaimed lead, copper and other fields of the utilization of solid waste and hazardous waste resources, which provides product oxygen for oxygen-rich smelting systems, with a general oxygen capacity varying between 3000-8000Nm3/h and purity of ＞80%. PKU Pioneer offers clients oxygen supply solutions targeted at their demands and tries all our best to optimize the oxygen plant configuration, thus promoting benchmarking project construction and ensuring lower energy consumption and higher efficiency of per unit oxygen, so as to help enterprises increase production and generate more profits.

PKU Pioneer has founded deep cooperation with over 10 enterprises of secondary metal recovery & smelting including Camel Group and Shen Lian Group, which are senior clients that have collaborated with PKU Pioneer for several times and highly recognized the oxygen generation process and technical services of PKU Pioneer.

According to the introduction by the principal of Tianneng Group, this project recycles waste lead-acid batteries to regenerate products to be used as the raw materials for storage battery production, lifting the proportion of reclaimed materials used in the production and implementing the green supply chain management, so as to promote Tianneng Group to build a closed green recycling industry chain with an integrated process of storage battery production, recovery, reuse and reproduction.
