I'm going to ignore molecular collisions, etc. and stick to the empirical world, which is where we engineers excel. Energy content of flour is 353 Kcal/100g. This equals 1.477 MJ/100g Energy content of gasoline is 46.5 MJ/kg, or 4.65 MJ/100g So, what this tells us is that gasoline has a much higher energy density than flour. In practical terms, this means ...

MEA is the most common scrubber solution the remove CO2, its been used for many decades. Calcium hydroxide is also common, but then there is solid calcium carbonate waste. Long ago, before I retired, there was more sulfur in flue gas so the carbonate was contaminated with calcium sulfate. I am not up to date on current technology but I am sure you can find ...

Total worldwide demand for sodium carbonate is about $0.6\,\mathsf{Tmol}/\,\mathsf{y}$. Total worldwide carbon dioxide emissions from fossil-fuel burning and cement production are about $800\,\mathsf{Tmol}/\,\mathsf{y}$. So either this approach would have a negligible effect on carbon dioxide emissions, or it would leave you with a lot of unwanted sodium ...

Ritmesh, just to be clear: are the iron parts cleaned in MEK before zinc coating, or are the zinc-coated iron parts corroding after being exposed to MEK during service as drum clamps? I ask because the the usual process for pre-zinc dip coating is an initial acid wash and rinse/dry, not an MEK cleaning dip. Also please note 35μm of zinc is not very thick and ...

This is because the manufacture of NaOH requires energy, and if that energy comes from fossil fuels, then the net gain of the overall process is either zero or less than zero. Net-positive CO2 sequestration requires finding a natural source of the chemical reactant. One such source is the found in the rock formation called an ophiolite (specifically, the ...

OnShape is a useful free (if ou make your designs public) 3D CAD program. There's an introductory tutorial showing some of the techniques to create sheet metal cylinder on YouTube TechProductDesign channel. Figure 1. The pipe with hole extruded from angled plane. Note the gap at the rear to allow the sheet metal flattening. Figure 2. The flattened sheet ...

If you have opportunity, just measure it. Resulting chart curve's equation can be estimated by a regression equation. Differentiate it for a given time and find the instantaneous rate.

To summarize: To get the cleanest possible combustion of fuels like garbage, you need the highest possible combustion temperature and the smallest possible particles of fuel to burn, which contains no non-combustibles like metal and glass. Thus you need to significantly pre-process the waste feedstock and construct a specially-designed burner system, both of ...
