I recently had to put conveyor system in Class I Div II area, what we did was go with a gas tight conveying system which had a very low n2 pressure/purge applied thus removing one of the three components required for fire/explosion.
I also used to deal with a similar issue all the time with...
One local vendor proposed a vertical screw conveyor, which may be appropriate if you have a well known and well behaved solid (like coal ash), but as a first of a kkind design our materials may come out with irregular sizing or possibly a bit wet/sticky. Am looking to be pretty conservative for...
Hi,
Ilve been doing chemical plant projects from conceptual design, through detail engineering and contruction for the last 15+ years. When we prepare the +/- ~20% cost estimate (based on pfd/pid/no takeoffs) we allow 15% of total installed cost for home office engineering, and 5% for field...
I am looking to use VFDs for two new blowers (maybe 8 to 10" water delta p max) downstream of a large evaporator, filter system, and condenser, discharging into a vent gas scrubber header. Inerts flow comes from dust collector cleaning with n2 and leakage on gasketing of evaporator (under...
Hi, I am looking for vendors for a bucket elevator or tube chain conveyor of 316LSS construction (possibly 304SS), rising maybe 40 feet vertically within a plant. Material is somewhat like coal ash.
Other mitigating factor is it will be in Italy although US companies would be considered...
I have designed systems to do this, but not run them for extended periods.
I would suggest working the problem through the major carbon drum/bed supplies such as calgon, who will give you adsorption isotherms and make some suggestions.
How frequently are you breaking through? have you tried to...
Packing vendors give away the correlations you are looking for, Koch and Glitsch had good old manuals as well as a recent favorite - Jaeger. Ask these sizing techniques will give you a good ballpark diameter based on gas and liquid flows.
A little leg work will get you in the right ball park...
If you put something in that can plug as part of the primary breathing device, I would commonly put in independant over/under pressure protection.
I have never heard of inert gas blanketing being required for sulfuric or demin water storage.
Is anyone aware of a good alternative to Siloxirane 2032 that would be readily available in Europe (Italy/Germany)?
Application is atmospheric pressure, boiling (~95 to 100C) 5% sulfuric acid with other organic acids present as well (pH 1-ish). Tanks to be coated are 316LSS.
