Hello,
My plant produces high density polyethylene and the final product is pelletized resins after extrusion.
My problem is that when the molten polymer is exposed to atmospheric air, it catches fire. Last week, it happened again, and this time the extruder die plate caught fire although very...
The problem I face in plant is to determine the maximum angle of closure from full open before the valve starts to cavitate. I am working on a project to implement partial stroke test on valve on-line and need to determine to what max. angle the valve is allowed to stroke before cavitation kicks...
Does anybody know anything about Twisted Tube Heat Exchanger? It claims that its performance is better than convectional HE. Due to the use of twisted tube inside, no baffles are used so the weight is relatively lighter and smaller. Also it is vibration-free. Any comments welcome. Thanks.
I work in a petrochemical plant producing HDPE. Ethylene is polymerised in the reactor and its product is further extruded into HDPE pellet.
My new assignment is to implement Safety Instrumented System (SIS) in the plant. We use HAZOP as a PHA tool
to identify the potential hazards and actions...
I work in a HDPE petrochemical plant. Can anybody help by educating me the way to estimate the quantity of VOC (mainly ethylene, isobutane, hexene) fugitive emissions to the atmosphere through compressors, rotary valves, pipe flanges, control valves and other process equipment. Hydrocarbon...
