Apr 07, 2014 Like chillers, cooling towers are rated in terms of tonnage – specifically how many BTU/Hr they can disperse through the heat of vaporization. As we mentioned in Part 2, what is known as a “refrigeration ton” differs somewhat from what is known as a “cooling tower ton”. A refrigeration ton is equal to 12,000 BTU/hr.

Apr 10, 2015 Distillation slightly limits the molecular diversity that may exist within the base oil, but does not completely eliminate nonessential molecular structures. This is important because unnecessary molecular structures produce variations in the base oil’s performance. The ideal lubricant’s chemical composition is one in which the molecular ...

Dec 01, 2021 Nitrogen is obtained from liquefied air through a process known as fractional distillation. How can you separate nitrogen from a mixture of nitrogen and oxygen? It is usually done by fractional distillation at very low temperatures. It can also be done by membrane separation. About 78 per cent of the air is nitrogen and 21 per cent is oxygen.

Dec 23, 2021 My name is Gail Tverberg. I am an actuary interested in finite world issues - oil depletion, natural gas depletion, water shortages, and climate change. Oil limits look very different from what most expect, with high prices leading to recession, and low prices leading to financial problems for oil producers and for oil exporting countries.

Oct 17, 2010 The particulars of the distillation process are dictated by the taste of the final product. Taste is obviously not a criterion for automobile fuel, but you still have to choose what you ferment carefully. Fermentation is essentially yeast “eating” simple sugars and excreting alcohol and carbon dioxide.

Sep 17, 2019 Most rubbing alcohol is made from isopropyl alcohol or isopropanol in water. Isopropyl rubbing alcohol is commonly found at concentrations from 68% alcohol in water up to 99% alcohol in water. The 70% rubbing alcohol is highly effective as a disinfectant. Additives make this alcohol bitter-tasting to try to prevent people from drinking it.

The Distillation test (ASTM D-1160) compares the boiling temperatures of standard molecular sizes (fractions) of new fluid with those of used fluid. As heat transfer fluid overheats, some of the lighter fractions will vaporize and gas off. The average boiling temperatures of the remaining fractions (now comprised of larger molecules) will be ...

UV light kills bacteria, viruses, and some cysts. It does not kill Giardia lamblia cysts or Cryptosporidium parvum oocysts, which must be removed by filtration or distillation. UV is not recommended if the untreated water has a coliform content exceeding 1,000 total coliforms or 100 fecal coliforms per 100 milliliters. Click to see full answer.
