April 20, 2025 – The chemical industry in Guangxi has witnessed significant construction progress. On April 12, the integrated project of hydrogen peroxide-based propylene oxide (HPPO) and polyether polyols by Guangxi Huayi Chlor-Alkali Company achieved a crucial breakthrough. The extraction tower, a core equipment of the 300,000-ton-per-year hydrogen peroxide unit, was successfully hoisted and then assembled at high altitude with the oxidation liquid separation tank. This milestone follows the successful hoisting of the oxidation tower and hydrogenation tower, signifying the completion of the entire installation process for key equipment of the project.
The extracted tower plays a vital role in separating hydrogen peroxide from the working fluid, aiming to obtain hydrogen peroxide with a concentration of up to 50%. The successful assembly of the extraction tower and the oxidation liquid separation tank marks the successful conclusion of the ultra-large equipment hoisting project, laying a solid foundation for the project to reach the intermediate handover stage by the end of this year. According to AsiaMB, as a significant part of the third phase of Huayi Qinzhou Chemical New Materials Integration Base, this project has a total investment of 5.5 billion yuan. It includes multiple production units and supporting facilities such as a 250,000-ton-per-year hydrogen peroxide unit, a 300,000-ton-per-year propylene oxide unit, and a 200,000-ton-per-year polyether polyol unit. Since its commencement in November 2023, the project further advanced the pile foundation engineering, primary pipeline installation, and main road construction in May this year, and is expected to enter the commissioning phase in 2026.
Invested and constructed by Shanghai Huayi Holding Group Co., Ltd., the Huayi Qinzhou Chemical New Materials Integration Base project is a landmark for Guangxi in undertaking industrial transfer from the eastern region and an important achievement of the cooperation between Guangxi and Shanghai. With a huge investment scale, it ranks among the top industrial projects in Guangxi, with a total investment of nearly 100 billion yuan. Currently, the first and second phases of the base have been put into operation in 2021 and 2022 respectively, and the third phase has been under construction in an orderly manner since 2023, ensuring a seamless connection among all phases. Once completed, the project will attract numerous downstream and related industrial projects, contributing to the establishment of a new regional industrial development model of “capital and technology output from the Yangtze River Economic Belt – high-end manufacturing in Qinzhou – products for the ASEAN market,” and playing a profound role in promoting the construction of high-end chemical new material industry clusters facing ASEAN.
