Removal Mercaptan From LPG ; Can this process be reversed?

There is a lot of talk about the mercaptan removal process in LPG. Some people say it can be reversed, while others insist that it’s not worth the massive investment. So, what’s the verdict? The mercaptan removal process is definitely not reversible. The reason is simple: mercaptans are a by-product of the oil refining process, and they are not removable without damaging the equipment and making the whole process much more expensive.

In other words, if you want to remove mercaptans from your LPG, you’ll have to invest in specialized equipment and do it right – there’s no turning back once you start! The Mercaptan Removal Process

Mercaptans are a by-product of the oil refinery process. It is a naturally occurring chemical in the crude oil, and it is most noticeable at high concentrations in an oxidized medium. The main difference between mercaptans and butyric acid is that mercaptans are toxic at low concentrations, but they make up for it with their ability to cause damage at higher concentrations (e.g. carcinogenic compounds). 

Another thing about mercaptans is that they don’t evaporate easily – so if you were to find an open bottle of (for example) cooking spray containing mercaptan, it would probably contain poisonous fumes well beyond its shelf life.
