“Don’t put them in a fluid bed.” I often hear this comment about sticky solids from plant operators and engineers because they’ve had many bad experiences with fluid beds. They end up spending countless hours cleaning out a plugged distributor, opening a discharge chute or banging on the vessel to get the solids to flow. They say the solids are too sticky to fluidize. Let’s face it: sticky solids need special attention. But first, we must identify the source of the stickiness. Almost all fine solids, when wet, are sticky. Many others clump due to a variety of factors including stickiness (see: “Clamp Down on Clumping”). Only a few of those factors come into…
