Removal of Residual Acetaldehyde from Polyester Polymer Particles |
| abstract |
According to one embodiment of the invention, a polyester polymer particle containing residual acetaldehyde at a temperature in the range of 130 to 195 ° C. is introduced into a container to form a particle bed in the container; Flowing gas through at least a portion of the particle bed; And collecting the finished particles having a reduced amount of residual acetaldehyde from the vessel. In this way, there is no need to introduce a hot flow of gas at the high flow rate otherwise required to heat the cooled particles to a temperature sufficient to strip acetaldehyde. Rather, because the hot particles quickly heat the gas to the particle temperature, the method can be effective to strip acetaldehyde in a reasonable time, if desired, despite the gas being introduced into the vessel at low flow rates and low temperatures. To provide. |
