Abstract

A method of transporting polymer pellets, in which in the pneumatic transportation of hygroscopic polymer pellets, the transportation can be performed through easy means without increasing of the water content of the polymer pellets; and a relevant method of storing polymer pellets. The method of pneumatic polymer pellet transportation involving the pneumatic transportation of polymer pellets together with a pressure gas flow through a transportation piping is characterized by including the gas dehumidifying step of reducing the water content of the gas used in the pneumatic transportation of polymer pellets so as to regulate the dew point of the gas to 0°C or below; the gas compression step of compressing the gas having its dew point regulated to 0°C or below in the gas dehumidifying step; the pressure gas feeding step of feeding into the transportation piping the pressure gas having been compressed in the gas compression step at a rate of 50 to 600 Nm3/hr per ton of polymer pellets; and the transportation step of carrying out the pneumatic transportation through transportation piping of the polymer pellets together with the pressure gas flow having been fed into the transportation piping in the pressure gas feeding step.
