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.
