Product detail description

Caustic Soda Lye is Sodium Hydroxide in solution. The solution can be diluted to 50% depending on intended application. Caustic Lye 50% is widely used in pulping of wood for making paper, as a cleaning reagent in bottling plants, storage tanks, textile industries as well as effluent treatment in oil and soap manufacturing.

Caustic Soda Lye is Sodium Hydroxide in solution. The solution can be diluted to 50% depending on intended application. Some gold miners in trying to bypass the challenge of having to open bags of caustic soda, are opting to install tankers onsite for storage of caustic lye, the introduction of which is controlled by a series of valves.

Caustic Lye 50% is widely used in pulping of wood for making paper, as a cleaning reagent in bottling plants, storage tanks, textile industries as well as effluent treatment in oil and soap manufacturing.

The above processes in most instances have to dilute the 50% Lye further before use. Major takers of caustic soda flakes are more often therefore able to draw also Lye 50% depending on availability of storage, costs, safety related issues and product form available.

4. METHOD OF APPLICATION

Tankers of lye are pumped straight into storage tanks on site. They are they channeled into the reacting chambers using a series of pipes and valves to control dosage rates.

Handling and safety challenges are reduced when using caustic lye.

Caustic lye dosage systems are normally operated together with ancillary equipment like pH meters to regulate pH-related chemical reactions. For example in gold leaching, one needs to monitor pH of leach reaction and adjust dosage accordingly.

Product application

Synonyms:           Glacial acetic acid; Acetic acid solution; acetic acid 50%;  acetic acid, of a concentration of more than 10 per cent, by weight, of acetic acid; Acetic Acid Glacial BP; Natural Acetic Acid; Acetic acid (36%); Acetic acid, food grade; Acetic Acid Glacial; GAA; Acetic Acid, Glacial 

It is a colourless liquid that when undiluted is also called glacial acetic acid. It has a distinctive sour taste and pungent smell.


Acetic acid uses:  
Additive in industrial explosives in Mining.

Other uses include use of acetic acid in the production of vinyl acetate monomer,  acetic anhydride and ester production. 

 

Chemical gassing agents -In the case of emulsion explosives, using Acetic acid can accelerate the gassing process. The chemically gassed emulsions may take 40 – 50 minutes for completion of gassing within the blast holes, particularly when the emulsion is colder.

In cases where acetic acid is used, it is added to the emulsion prior to gassing, the desired amount of acid is mixed in the emulsion, before adding the gasser.

A gassing solution comprising sodium nitrite in water together with the selected enol compound and acetic acid is introduced into the emulsion explosive at the blast hole by entraining the gassing solution into a stream of the emulsion explosive using pumps.

The solution pH is an important parameter in the gassing of emulsion explosives due to the high cost associated with acid addition therefore a pH value should preferably be maintained at 4.1 or below.

4.Environmental impact

 

-       Acetic acid biodegrades readily under both aerobic and anaerobic conditions.

 -        Acetic acid does not absorb light with wavelengths >290 nm(4), and is not expected to be susceptible to direct photolysis by sunlight(SRC).

-        Incase of spillage neutralize spill with soda ash or lime.
