National Pipe Network Group said a domestic first trial of sequentially transporting fuel methanol through a long-haul refined-oil pipeline was successfully completed in Xianyang, Shaanxi. Two test sets covering high- and low-flow regimes and start-up/shutdown conditions validated the process adaptability for sequential methanol batching across complex terrain and multiple operating modes.

National Pipe Network Group said a domestic first trial of sequentially transporting fuel methanol through a long-haul refined-oil pipeline was successfully completed in Xianyang, Shaanxi. Two test sets covering high- and low-flow regimes and start-up/shutdown conditions validated the process adaptability for sequential methanol batching across complex terrain and multiple operating modes. The group's research institute director Zhang Duìhong said the trial provides an engineering basis for routine, large-scale methanol transport and underpins future construction of a west-to-east methanol transport corridor.
