Bentonite layers from an ancient deposit of weathered volcanic ash tuff in Wyoming Gray shale and bentonites (Benton Shale; Colorado Springs, Colorado). Bentonite (/ ˈ b ɛ n t ə n aɪ t / BEN-tə-nyte) [1] [2] is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite.
Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, have been used for clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium bentonite and calcium bentonite.
The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. Included is growing zone data, relevant to farmers and agricultural scientists. This is unrelated to ethanol production, which relies on starch, sugar and cellulose content instead of oil yields.
Several different types of bentonite can be found; however, potassium bentonite is the main one associated with the Deicke and Millbrig eruptions. The Deicke and Millbrig K-bentonite layers can be found from Alabama to New York to Minnesota. These K-bentonite layers are up to a meter thick in some locations. [8] Such thickness is unique.
Bulk Phosphate Stowage Factor (SF) about 0.90 m 3 /ton (32 ft 3 /ton) In fact, Ship A has space for 55,000 mtons on her holds 70,000/0.90 = 77,000 mtons or 2,470,000/32 = 77,000 mtons (rounded) However, Ship A can only take 55,000 mtons in weight of Bulk Phosphate before Ship A loadline is submerged Stowage Factor (SF) Example 2: Ship B
Metric regions commonly use the tonne of oil equivalent (toe), or more often million toe (Mtoe). Since this is a measurement of mass, any conversion to barrels of oil equivalent depends on the density of the oil in question, as well as the energy content. Typically 1 tonne of oil has a volume of 1.08 to 1.19 cubic metres (6.8 to 7.5 bbl).
The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil.It is approximately 42 gigajoules or 11.630 megawatt-hours, although as different crude oils have different calorific values, the exact value is defined by convention; several slightly different definitions exist.
Bentonite: Several million tons of calcium-type bentonite is found on Kimolos and Milos and is often converted for higher swelling capacity by treating with sodium carbonate. Greece is the second largest bentonite producer after the United States. Chromite: Hosted in peridotite, ophiolites and dunite. Near Vourinos is a deposit with 1.5 million ...
