I have an open topped, agitated vessel, taking a flow from an air stripper. At flows greater than 130m³/hr the vessel starts to "oscillate" and flex. This is rather worrying as it is a GRP vessel and the oscillations could damage it.I believe the vessel might be slightly scaled which might be...
We do have background organics in the cauastic scrubber but these were at normal levels ( ~ 10 ppm). I have heard of cases were the caustic has leached out trace contaminants from new plastic pipework but this is not the case here. Solids ( hardness salts ) have also given problems in the past...
I have recently had problems with caustic foaming in a 10% w/w caustic scrubber removing trace quantities of chlorine from air. The problem appears to be temperature related but I can not find any theory or data behind the phenomena to calculate the operating temperature that will prevent the...
