Folks,
I've poked around here quite a bit with no luck so hopefully the answer is not staring me in the face.
We have a chemical storage tank inside a containment bund of sufficient volume to hold 150% of the tank's volume, as one may expect. The question has arisen, what if there is a...
Hi Folks,
I am having a real Chem Eng 101 Brainfreeze. My embarrassment at having to ask this question, however, is outweighed by my desire to get things straight in my mind.
I have an essentially pure solvent in a storage tank (relatively high boiling, benign solvent, smallish, in plant...
Hi,
We are compounding glycols with surfactants and other powdered additives in a large agitated tank. Powder addition is generally brute force bag breaking over an open hatch. Glycol is heated to enhance dissolution of solids.
There are thus two problems associated with the tank...
Dumb q. for the assembled cognoscenti:
I'm working through the hydraulic modelling for my first wet well. Despite a reasonable amount of experience with pumping systems I haven't really worked with sub pumps before. Simple question on its face:
Are there any suction friction losses to...
Any advice as to standard guides for the creation of robust, standardized control narratives? Our normal process is this:
- develop PFDs
- develop P&IDs including an intermediate level of info density (say, element bubbles and display bubbles, maybe alarm states if the dwg doesnt get too busy)...
Hi folks,
I've been asked to assist with some design which is a bit beyond my experience and I keep getting trapped in some circular thinking -- I'm hoping someone can help me sound this out a bit.
An existing process tank contains a hydrocarbon below its boiling temperature. The tank is...
Does anyone have experience installing LEL and O2 sensors such that they are measuring the environment within a tank? The tank is blanketed with Nitrogen (Fisher ACE controller on the inlet side, Protectoseal PVSV on the outlet) and we require the sensors to confirm the blanket.
The further...
Folks,
Seeking solutions for the processing of a 35% solids slurry (metal plating wastes) where it is desired to evaporate the free liquid completely. My thinking had been along the lines of an internally agitated batch mixer/dryer or rotary dryer with internal flights, to allow good surface...
