摘要： The present invention relates to a method for transporting polyolefin particles in a polymer conveying system, comprising the steps of a) Subjecting the polyolefin particles to moist conveying gas to produce wetted polyolefin particles; b) Transporting the wetted polyolefin particles through at least one conveying line; and c) Controlling the amount of moisture in the conveying gas of the polymer conveying system as such that at the end point of the at least one conveying line the relative humidity of the conveying gas (RHCG) is 40% to 100%, the use of said method in an in-plant polymer conveying system, the use of said method for improving dust and/or angel hair removal in polymer conveying systems and the use of said method for increasing conveying capacity of polyolefin particles with a density of from less than 850 to 910 kg/m3.
