Dry Ice Is Perfect Industrial Cleaning Agent

When it comes to heavy-duty cleaning tips, a little known secret is that dry ice blasting is one of the best methods available. From getting chewing gum off of a city sidewalk to mold remediation, uses for dry ice spread across different industries and various levels of use.

Dry ice is the solid form of carbon dioxide. Its most common use is as a cooling mechanism; however, in recent years, various industries have found that it serves other uses.

Many of us think of dry ice as the wonderful substance that makes our fog machines function and our Halloween parties look eerie. We also think of science experiments exploding soda bottles when we think of dry ice.

But dry ice can be more than a stage prop: one of the most common uses of dry ice involves blast cleaning. Blast cleaning occurs when small pellets of dry ice are shot through a small nozzle using compressed air to get stubborn residue and grime off of industrial materials. Dry ice can remove ink, glue, oil, mold, paint or rubber without damaging the core material or equipment. Using dry ice to remove some of these substances can replace the need for sandblasting, water blasting or steam blasting, all of which require several applications to clean effectively.

Dry ice also can be used to clean other types of construction materials, including brick. The benefit of dry ice is that it is strong enough to remove just about anything -- from mold and mildew to water stains, bird droppings, wood carvings, but gentle enough to not damage the brick material.

It’s important to note, however, that using dry ice as a method of cleaning any industrial -- or other – materials should only be handled by those with adequate training. Improper handling of dry ice can cause severe cold burns to the skin; individuals who aren’t well versed in its uses might find that it is easier to sustain a burn than they think.

Dry ice often produces a great deal of condensation as it is expelled, which makes it hard to distinguish between the fog and the dry ice, itself. Because these burns can cause such damage to the skin, dry ice cleaning applications should always be conducted by an experienced employee or a company that specializes in this type of cleansing method.

Homeowners and industrial factories alike can benefit from dry ice cleansing applications. Working with a reputable dry ice company will ensure that your home, commercial building or the surrounding area will look new and clean without the worry of structural damage to the substrate or machinery you are cleaning.

How many grams of iron can be produced from 4.50Kg Fe2O3?

Hematite, Fe2O3, is an important ore of iron. The free metal Fe is obtained by reacting hematite with carbon monoxide, CO, in a blast furnace. The reaction is
Fe2O3 (s) + 3CO(g)--> 2Fe (s) + 3CO2 (g)
*how many significant figures would i use for this answer? should i use as many significant figures thats in 4.50?

4500g Fe2O3 * (1 mol Fe2O3 / 159.68g Fe2O3) * (2 mol Fe / 1 mol Fe2O3) * (55.84g Fe / 1 mol Fe) = 3147g Fe

This of course assumes 100% efficiency. Hope this helps!
