Reactor fouling
WebAug 7, 2024 · Reactor configuration and operation. Figure 1 is a schematic of the experimental setup of a fluidized membrane reactor developed to observe fouling behavior under GAC fluidization. The fluidized membrane reactor was fabricated by using transparent acrylic column with 50 cm long by 2.5 cm diameter (effective volume 0.245 L). WebProcess stream fouling can lead to increased pressure drop in the exchangers and furnace. In some cases the fouling is so severe that the hy-draulic limits are reached, the throughput is re-duced, and significant processing incentives are …
