Why does silver tarnish more in petroleum refinery?
silver gets tarnished near petroleum refineries because a gas called hydrogen sulphide is released from refineries which reacts with silver to form a black substance called silver sulphide.
Will Sterling Silver tarnish if you are on Antobotics?
Silver tarnishing is a reaction of silver with oxygen to create silver oxide, silver's version of rust.Silver is antimicrobial, but the bacteria have nothing to do whatsoever with the silver tarnishing.So YES, silver will tarnish as long as it has contact with oxygen....and before someone chimes in, argentium sterling also tarnishes, just much more slowly.
How do you convert scrap silver to pure silver?
This is not a process you can do yourself at home. Silver items need to be sent to a professional refinery that has the industrial equipment and chemicals required to separate metal alloys. If you have a significant amount of silver to refine (several kilos or more) it may be worth findings a refinery and sending material in directly. Otherwise, small amounts are best handled through reputable jewelry stores or jewelry supply outfits.
Why is cracking used in crude oil or petroleum refinement?
In oil refining, cracking is the process of breaking large molecules into smaller molecules for which the refinery has more use, either as a product or as a feed stock to make something else.
Why do silver articles become black after some time when exposed to air?
Sulphur and Nitrogen dioxide and trioxide gases present in the air, as pollutants, react with the surface of the silver to form black compounds such as Silver nitrate and Silver sulphide.
Why does silver get tarnished near a refinary?
Silver is more likely to tarnish near a petroleum refinery because hydrogen sulphide released from refineries, reacts with silver to form a black substance called silver sulphide.

How is oil made into gas?
After crude oil is removed from the ground, it is sent to a refinery by pipeline, ship or barge. At a refinery, different parts of the crude oil are separated into useable petroleum products. Crude oil is measured in barrels (abbreviated "bbls"). A 42-U.S. gallon barrel of crude oil provides slightly more than 44 gallons of petroleum products. This gain from processing the crude oil is similar to what happens to popcorn, it gets bigger after it is popped.
What is a Hydrotreater in an oil refinery?
A hydrotreater is a chemical engineering plant that normally deals with hydro treating. Hydro treating is the process of removing sulphur from the unfinished products. This process is more often used in refining petroleum products.
