Recently, Bainei Technology has continued to make breakthroughs in the field of petrochemical environmental protection: after successfully winning the bid for the alkali recovery unit at Yisheng Da Hua Petrochemical Co., Ltd., the company won bids for two key components of that company’s project aimed at reducing energy consumption and carbon emissions in its PTA production process – the multi-effect evaporation unit and the ash separation unit for alkali furnaces. The simultaneous award of contracts for these various types of installations not only demonstrates Bainei Technology’s capability to provide end-to-end services, ranging from \"core equipment\" to \"supporting systems\", but also reinforces its status as a technical leader in energy conservation and carbon reduction within the PTA industry through sophisticated design solutions. As a leading global producer of PTA, Yisheng Shenghua has an annual PTA production capacity of 5.5 million tons. The energy-saving and carbon-reduction renovation project it has launched is a key measure to meet the **\"dual carbon\" goals and address the issues of high consumption and high emissions in the PTA industry. It is understood that the treatment of high-salt waste liquids generated during the PTA production process, as well as the efficient recycling of waste materials such as ash from alkali furnaces, represent the key challenges in enabling the industry to achieve a green transformation. The projects won by Bainei Technology cover all the key stages of the entire process – from centralized treatment of waste liquids to efficient recovery of energy and precise purification of solid waste. These projects help achieve the three main objectives of reducing energy consumption, recycling solid waste, and ensuring compliance with emission standards, and they serve as an important model for energy savings and carbon reduction in China’s PTA industry.

The projects that Bainei Technology has won in succession feature \"full-system coverage and high adaptability\". In the previously won projects, for the two alkali recovery units, the company’s multi-core system for end-to-end design and process packages enabled efficient energy conversion during the alkali recovery process as well as compliance with environmental standards ； Among the newly won projects, the multi-effect evaporation units are designed for the treatment of high-salt waste liquids, while the alkali furnace ash separation units, through a detailed design of multiple systems, enable the resource recovery of sodium carbonate and sodium bromide from the ash. This works in synergy with the alkali recovery units that were previously acquired, further improving the closed-loop processing chain of \"waste liquids – energy – solid waste\". The reason why Bainei Technology has been able to win multiple projects from Yisheng Shenghua lies in its strong technical expertise and proven ability to meet various requirements. As a platform for the transformation of scientific and technological achievements from Zhejiang University, the company holds over 60 authorized invention patents. Its developed \"PTA high-salt organic waste liquid thermal conversion, clean treatment, and resource utilization system\" was recognized as one of Zhejiang Province’s first international-level manufacturing products in 2023. This core technology has been successfully applied in major projects such as those carried out by Zhejiang Yisheng New Materials and Hainan Yisheng – it not only achieves zero discharge of PTA waste liquid and a sodium carbonate recovery rate of over 99%, but also generates high-pressure steam, helping companies reduce their production costs per ton of PTA by 35 yuan ； The project won by Yisheng Da Hua in this bid represents an extension and optimization of this core technology; for example, the flue gas treatment module of the alkali furnace system enables ultra-low emissions, while the purification system of the ash separation device further increases the recovery rate of sodium carbonate. Throughout the process, the core design principles of \"reduction, harmlessness, energy utilization, and resource recycling\" are upheld, which precisely meets Yisheng Da Hua’s needs for cost reduction, efficiency improvement, and environmental upgrades. This is also the key reason for their continued cooperation.
