    Yueyang, Hunan – Changling Petrochemical, a subsidiary of China Petroleum & Chemical Corporation (Sinopec) in central south China’s Yueyang city, attained HPPO (hydrogen peroxide-to-propylene oxide) technology in November 2013.

    The new technology, which is for the first time successfully developed by a Chinese company, has received three oversea patents and 11 domestic ones. Changling Petrochemical’s 100 kT/year HPPO facility is in the pipeline at this time and is planned to be completed within the first half of 2014.

    According to Sinopec’s website, polyurethane thermal insulation construction materials produced with propylene oxide derivatives can reduce construction period by two thirds and cut the cost by RMB25/sq.m ($4/sq.m). Currently 80% of China’s propylene oxide is yielded with the chlorohydrination method, which produces 50 tonnes of waste water and two tonnes of residue for each tonne of propylene oxide output. China stopped approving new projects using this method in 2011.
