Pickling fluids

Pigmented scars are also observed in iron, stone, silver and flour-mill employees. Cases of skin pigmentation from the external therapeutic application of iron salts, such as ferrous sulfate and ferric chloride, have been described. Hare (1951) reported red-brown, punctate, perifollicular pigmentation from deposition of iron granules on the forearms of a metal worker employed in pickling metal in hydrochloric acid. The pickling fluid contained iron salts in an acid medium. 

Acidic drugs, such as aspirin, and acidic foods, such as citrus fruits and pickling fluids, irritate ulcers. When consumed, these substances increase the acidity of the stomach juices, exacerbating the irritation to the stomach wall. On the other hand, antacids—which contain bases— relieve ulcers. Common antacids include Turns and milk of magnesia.

Procedure Into a standard distillation apparatus, alcohol still, or other means, place 1250 milliliters (42.2 fluid oz.) of vodka, and then distill the alcohol at 80 Celsius for about 4 hours. After 4 hours, remove the heat source, and then recover the alcohol that distilled over into the receiver flask or receiver container. Now, place this alcohol (which will be composed of about 90%+ ethyl alcohol), into a large seperatory funnel or equivalent, and then add in 50 grams (3.5 oz.) of pickling salt. Thereafter, vigorously shake the entire mixture for about 10 minutes. After 10 minutes, allow the mixture in your seperatory funnel or equivalent, to stand for about 30 minutes. Thereafter, drain-off the bottom water layer and excess salt, and thereafter, recover the upper alcohol layer. Now, place this recovered upper alcohol layer into a standard distillation apparatus, as illustrated in method 1 or similar, and then add in 500 milliliters (17 fluid oz.) of fresh battery acid. Thereafter, boil this mixture at 100 Celsius for about 6 to 8 hours, and allow the mixture to distill during this time. After 6 to 8 hours, remove the heat source, and then recover the diethyl ether from the receiver flask or receiver container. Then re-distill this diethyl ether using a standard fractional distillation apparatus or equivalent in the same manner as in method 1 (distill at 40 Celsius). Note the battery acid mixture left over, can be recycled, but it must be boiled to drive-off at least 1/3 of the total volume (to remove water). 

Downward solid flux of 0.2 to 500 g/s m with low values of 0.2 to 2 for waste water treatment, pickle liquor and higher values of 40 to 70 for mineral processing. Higher flux rates by factors of 3 to 10 up to fluxes of 800 g/s m can be obtained with the addition of flocculants. Fluid residence times 2-4 h solids residence times 4-24 h.
