Carbon dioxide cleaning was contemplated in the 1930s, and the "pellet" approach was developed in the 1970s by E.E. Rice, C.H. Franklin, and C.C. Wong. [4]: 276 The introduction of CO 2 snow cleaning, with its ability to remove sub-micron-scale particles, is credited to Stuart Hoenig of the University of Arizona , who first published on the ...
Sea foam washed up or blown onto a beach. Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms.

Long Retractable Sootblower utilizing steam as a cleaning medium. A sootblower is a device for removing the soot that is deposited on the internal furnace tubes of a boiler during combustion to prevent plugging of the gas passes and maintain boiler efficiency. The world market leader is Clyde Bergemann Power Group. [citation needed] Types of ...
Tube-axial fans - Tube-axial fans are similar to propeller fans except they are mounted in a tube or cylinder. Therefore, they are more efficient than propeller fans and can develop up to 3 to 4 in. wg (743.3 to 995 Pa). They are best suited for moving air containing substances such as condensible fumes or pigments.
The chemical composition of black carbon is much more varied, and typically has a much lower proportion of elemental carbon, compared with carbon black. [ 8 ] [ 6 ] In some definitions, black carbon also includes charcoal , a type of matter where the chunks tend to be too large to have an aerosol form as is the case with soot.
The pump of an evaporator may need to be changed if the evaporator needs to be used to concentrate a highly viscous solution. Fouling also occurs when hard deposits form on the surfaces of the heating mediums in the evaporators. In foods, proteins and polysaccharides can create such deposits that reduce the efficiency of heat transfer.
The Ramsbottom test is used to measure carbon residues of an oil. In brief, the carbon residue of a fuel is the tendency to form carbon deposits under high temperature conditions in an inert atmosphere. This is an important value for the crude oil refinery, and usually one of the measurements in a crude oil assay.
Planting trees is a nature-based way to remove carbon dioxide from the atmosphere, however the effect may only be temporary in some cases. [1] [2]Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.
