Abstract
A method for the long-distance transport of a liquid of methanol or a solution of methanol and at least one organic compound other than methanol, under pressure, through a pipeline installation in which the portions of the pipeline installation that contact said liquid consist essentially of carbon steel and/or low alloy steel, the sum of whose metallic components other than Fe is up to 5 wt. %, in which the water content of said liquid is limited to (a) the range of 0 to 35 wt. % if the content of the formate radical in said liquid is up to 0.05 wt. %, (b) the range of 0.25 to 35 wt. % if the content of the formate radical in said liquid is in the range of 0.05 to 2 wt. % and (c) the range of 0 to 35 wt. % if the content of the formate radical in said liquid is in the range of 2 to 3 wt. %, so that said liquid is transported under pressure while the volume ratio of the formate radical to the water content is kept at a ratio that does not permit the presence of more than 3 wt. % of the formate radical in the liquid.
