Calculations of settling velocity upon which vessel size is based assume laminar flow in the settling region, a premise which is usually far from accurate. Even when Re calculated from vessel dimensions, liquid depth, and flow rates is <2000, reality is that the geometry with which the 3-phase...
Any one-use absorbent will be prohibitively expensive for your sulfur rate. Several processes are available for scrubbing out the H2S and converting it to elemental sulfur, typically of low value. Your application is a good fit for a process offered by ThioSolv for converting the sulfur to...
