Definition - What does Desorption mean?
Desorption is a process in which an adsorbed species remains indefinitely in a static state at low temperatures of a substrate. When there is an increase in the temperature of the substrate, then there will arise a point at which the thermal energy of this adsorbed species may face the following things:
- Decomposition of molecular species happens and yields either surface species or gas phase products.
- Desorption of the species may take place and return into the gas phase.
Petropedia explains Desorption
During the production stages of crude oil, increased use of thermal technologies has come across as one of the issues in front of operators in recovery of the base oil. Thus, it is important to select a type of base oil that has low temperature for desorption, so that it can be removed easily from cuttings at low temperature.
Thermal desorption technologies are also helpful in appropriate endpoint disposal of waste solids from oil-based mud operations during onshore and offshore drilling processes. Thus, desorption technology helps in untreated and oil contaminated drilling waste in proper and safe disposal.
