Problems with transporting polycarbonate!
Thread Content
For transporting polycarbonate particles, is dense-phase transportation or dilute-phase transportation better? Please give me some advice, fellow travelers!
Friend, you do have quite a few questions. In terms of reducing energy consumption and minimizing material degradation, the dense phase has inherent advantages over the dilute phase. For you, pulsed plug flow is the best choice. Of course, there are certain limitations: the transmission distance is generally less than 150 m, and the pipe diameter is usually no larger than DN150
2# juaner So that means the distance for dilute-phase transport is longer than that for dense-phase transport? Is there then a requirement for the radius of curvature of pipes such as elbows?
That’s not the case; pulsed plug flow is just one method of dense-phase transport. Generally speaking, it’s no problem to transport in a dense phase for several hundred meters. However, the pipeline resistance is proportional to the mixing ratio and the length of the pipeline; in other words, when the distance exceeds a certain level, if it is necessary to maintain the mixing ratio at the dense-phase level, the pipeline resistance may exceed the typical supply pressure (usually 0.6–0.7 MPa). To accommodate this supply pressure, the longer the transmission distance, the lower the mixing ratio must be. Generally, for both dilute and dense phases, a diameter 6 to 8 times that of the pipe can be used; for pulsed plug flow, a larger diameter is required, so 10 to 15 DN can be adopted.
4# juaner Thank you for the advice!
According to the data, it should be a dilute phase.
I want to learn it too* learn* Polycarbonate is also a hot topic these days, right?
