Like brines, alcohols were readily available and widely used as antifreeze liquids in the early 1900s. Both methanol and ethanol offer excellent heat transfer and efficient freeze point depression. However, the alcohols have the distinct disadvantage of their low boiling points. During the summer months when the engines operate hot, significant amounts of the alcohols are lost because of evaporation. These evaporative losses result in costly make-up requirements. Additionally, the alcohols have very low flash points and potentially flammable vapors. These safety concerns have, particulady in recent years, caused the use of alcohols to be completely discontinued for most heat-transfer systems. 

A drawback of the liquid-type collectors is the danger of leakage and freezing. The former can be averted by appropriate junctions that permit dilatation, the latter by using antifreeze liquids as working media, for example, by integration into the hot water system of the farm for year-round performance.

Proper maintenance of jacks is essential for safety. All jacks must be inspected before each use and Inbricated regnlarly. If a jack is subjected to an abnormal load or shock, it should be thoroughly examined to make sure it has not been damaged. Hydraulic jacks exposed to freezing temperatnres must be filled with adequate antifreeze liquid. 

What Inspect jack components including (but not limited to) Load rating markings, Blocking, Antifreeze liquid (if used), and Lubrication.

QUENCH LIQUID SELECTION The choice of the appropriate quench liquid depends on a number of fac tors. Water is usually the first quench hquid to consider, since it is nontoxic, nonflammable, compatible with many effluent vapors, and has excellent thermal properties. If water is selected as the quench liquid, the tank should oe located indoors, if possible, to avoid freezing problems. If the tank has to be located outdoors in a cold climate, the addition of antifreeze is preferable to heat-tracing the tank, since overheating the tank can occur from tracing, thus reducing its effectiveness. 

Nature produces a tremendous amount of methyl aleohol, simply by the fermentation of wood, grass, and other materials made to some degree of eellulose. In faet, methyl aleohol is known as wood aleohol, along with names sueh as wood spirits and methanol (its proper name the proper names of all aleohols end in -ol). Methyl aleohol is a eolorless liquid with a eharaeteristie aleohol odor. It has a flash point of 54°F, and is highly toxie. It has too many eommereial uses to list here, but among them are as a denaturant for ethyl alcohol (the addition of the toxie ehemieal methyl aleohol to ethyl aleohol in order to form denatured aleohol), antifreezes, gasoline additives, and solvents. No further substitution of hydroxyl radieals is performed on methyl aleohol. 

The most widely known aleohol is ethyl aleohol, simply beeause it is the aleohol in aleoholie drinks. It is also known as grain aleohol, or by its proper name, ethanol. Ethyl aleohol is a eolorless, volatile liquid with a eharaeteristie odor and a pungent taste. It has a flash point of 55°F, is classified as a depressant drug, and is toxic when ingested in large quantities. Its molecular formula is CjHjOH. In addition to its presence in alcoholic beverages, ethyl alcohol has many industrial and medical uses, such as a solvent in many manufacturing processes, as antifreeze, antiseptics, and cosmetics. 

Whenever a hydrocarbon backbone has two hydroxyl radicals attached to it, it becomes a special type of alcohol known as a glycol. The simplest of the glycols, and the most important, is ethylene glycol, whose molecular formula C2H4(OH)2. The molecular formula can also be written CHjOHCHjOH and may be printed as such on some labels. Ethylene glycol is a colorless, thick liquid with a sweet taste, is toxic by ingestion and by inhalation, and among its many uses is a permanent antifreeze and coolant for automobiles. It is a combustible liquid with a flash point of 240"F. 

In all circumstances it is important to ensure that the inhibitor is chemically compatible with the liquid to which it is added. Chromates, for example, cannot be used in glycol antifreeze solutions since oxidation of glycol by chromate will reduce this to the trivalent state which has no inhibitive properties. 

Ethylene glycol is widely used as an antifreeze. Glycerol is formed as a byproduct in making soaps. It is a viscous, sweet-tasting liquid, used in making drugs, antibiotics, plastics, and explosives (nitroglycerin). 

Some data concerning the activity of antifreeze chemicals are presented in Table 14-1. Inspection of Table 14-1 shows that there are two different types of antifreeze chemicals, that is, liquids that are miscible over the full range of concentration with water and salts, often salts which are soluble only to a certain amount. In the case of liquids, a mixture of 50% by weight with water is given. In the case of solids, the ethylene glycol forms with water an... 

The classic antifreeze agents in heat-transfer liquids are brine solutions and alcohols. 

Highly viscous petroleum oil containing 30% to 80% water can be transported through pipes more efficiently when a 1 1 mixture of washing liquid and antifreeze (i.e., ethylene glycol with borax) is added to the oil in amounts of 0.002% to 0.2% by weight. In addition to increased efficiency of transport, reduced corrosion of pipes can be achieved [893]. 

RO can recover metals, antifreeze, paint, dyes, and oils in the retentate while generating cleaned up wastewater permeate for disposal. RO is also used to reduce the volume of waste liquids (e.g., spent sulfite liquor in paper manufacturing). Wastewater treatment application removals of 95 percent TOC, > 90 percent COD, > 98 percent PAH compounds, and pesticides > 99 percent have been seen [Wilhams et al., chap. 24 in Membrane Handbook, Sirkar and Ho (eds.), Van Nostrand, 1992].
