Alkaline stain removers are mostly used in the removal of oil-based stains via the process of saponification. [6] Sodium hydroxide is also commonly used in drain cleaners. It allows grease and other oils to dissolve into aqueous solutions like water. Other alkalis such as potassium hydroxide (much stronger than sodium hydroxide) are also used ...
Automotive oil recycling involves the recycling of used oils and the creation of new products from the recycled oils, and includes the recycling of motor oil and hydraulic oil. Oil recycling also benefits the environment: [ 1 ] increased opportunities for consumers to recycle oil lessens the likelihood of used oil being dumped on lands and in ...
Cold mix asphalt is often used on lower-volume rural roads, where hot mix asphalt would cool too much on the long trip from the asphalt plant to the construction site. [18] An asphalt concrete surface will generally be constructed for high-volume primary highways having an average annual daily traffic load greater than 1,200 vehicles per day. [19]
Chip seal products can be installed over gravel roads to eliminate the cost of grading, road roughness, dust, mud, and the cost of adding gravel lost from grading. Adding chip seal over gravel is about 25% of the price of resurfacing with asphalt, $170,000 for a 4-mile project done in Minnesota [6] compared to $760,000 had it been redone with ...
A de-asphalter is a unit in a crude oil refinery or bitumen upgrader that separates asphalt from the residuum fraction of crude oil or bitumen.The primary purpose of the separation is to remove contaminants (asphaltenes, metals) from the feed that would cause rapid deactivation of catalysts in downstream processing units.
Maltenes are the n-alkane (pentane or heptane)-soluble molecular components of asphalt, which is the residue remaining after petroleum refiners remove other useful derivatives such as gasoline and kerosene from crude oil. Asphaltene compounds are the other primary component of asphalt.
