LPG Mercaptans Removal Services
Mercaptans are also called thiols. These organosulfur molecules constitute hydrogen, sulfur, and carbon, and they have a pungent odor smell like garlic or rotten cabbage. You can find these compounds in the waste products of metabolism in living beings and oil and gas. Mercaptans are mainly used for gas detection purposes despite having a troublesome odor. For example, people use non-corrosive Mercaptans to detect natural gas.
The concentration of Mercaptans varies widely in oil and gas. This concentration also changes in the case of odor intensity and side effects. Some common side effects of Mercaptans include corrosion of pipelines and poisoning of solid absorption beds and catalysts. Examples of these catalysts include alumina and silica gel.
Industries use several methods for Mercaptan removal for LPG and purification. Sometimes, even the government lends a hand in removing these compounds.
People apply several methods to remove and purify the Mercaptans. We will discuss the most prevalent methods used in their removal and purification below:
- The use of chemical scavengers is one of the most common methods for Mercaptan removal. They react with the Mercaptans to form a compound that does not have corrosion capacity or foul odor.
- People also use acrolein as a scavenger compound for removing Mercaptans. This highly efficient molecule reacts quickly with Mercaptans and sulfides. However, there is limited commercial use of acrolein in field and plant operators because it is a toxic substance.
- Another vital method used to remove Mercaptans is getting them to react with potassium hydroxide, sodium hydroxide, or a combination using similar compounds.
- Oxidation using strong reagents like hydrogen peroxide, sodium hypochlorite, and O2 is also applicable for Mercaptan removal and purification.
- Mercaptan is oxidized and purified using biological removal processes, ozone, and catalytic oxidation processes.
Mercaptan removal helps to reduce sulfur emissions. Failing to do so leads to the emission of Mercaptan-containing compounds, and combustion leads to SOx formation. So, removing and purifying these toxic compounds is necessary for refined products and feedstock.
