Hi everyone. I am an engineering student. I read something called dry ice blasting and hazardous waste disposal while browsing net. Well I don’t know why, but I am curious to know about it. I know about traditional labor intensive methods like scrapers, wire brushes, sand blasting and pressure washing. I know dry ice is basically solid form of CO2, but I have no clue about this dry ice blasting and industrial cleaning .
Can somebody throw some light on this or at least suggest some site where I can find some info on this.

Try goggling "dry ice blasting", it's good for at least 126,000 hits.
 
Just in case you didn't pick up on it...this is not the place to get a straight answer to a serious question.

The tip-off is that we got funny pictures next to our names.;)

I always have a hard time goggling "dry ice blasting" myself. Googling works just fine though. ;)
 
-like Dan and Drifa said, you can use google.
-or you could ask any physics or thermodynamics professor
-or think logically about the name
dry ice is CO2 (as you correctly stated.)
blasting is probably referring to some sort of high impact.
therefore we can safely assume they're using using a device to propel dry ice pellets at a high speed to clean a surface. It will instantly sublimate back to its natural gas state which is why its being called "environmentally safe alternative."

Wait a minute!!!!!!!!! What's so funny about my avatar? And I get straight answers to serious questions (well, at least once I did).

Sweetie dear, we're talking about sending particles of dry ice at high velocity here. I'd feel much better if you'd wear the goggles.

Yes, but the answer guy is gone now.

They lost me at "Supersonic speed". Last I knew that implied jet airplanes and Chuck Yager and "The Right Stuff". I have a friggin machine that puts out 230 psi and I don't believe it's breaking any sound barriers. Any physics whizzes out there? Is 230 psi really supersonic?

"Supersonic" refers to a speed, not a pressure.

Sound travels roughly one mile every five seconds. Things that move faster than that are supersonic. Things that move slower than that are not.
 
So any particle as small as a grain, propelled by 230 psi can travel a mile every 5 seconds (speed wise)?

It might not make it a whole mile, but it could make it a couple inches at that speed.
 
So I can make rice crispy sounds by propelling grains of rice. Neat.
Seriously, I just never thought that stuff was moving that fast.
 
omaha steaks come packed in dry ice to keep them frozen in transit. When my ex gf and I ordered a bunch of steaks, the dry ice was still mostly intact (it hadn't evaporated), so we threw it off her 17th story balcony into the pool on the 14th floor.

It bubbled for the longest time, but nothing 'blasted' or exploded. bummer. People did get concerned and security got called and they circled the pool for a while. We laughed for a while and then ate steaks.
