The Claus process is the most significant gas desulfurizing process that recovers sulfur from the gaseous hydrogen sulfide found in raw natural gas and from gases derived from refining crude oil and other industrial processes.
Hydrogen sulfide (H2S) is a smelly, corrosive and highly toxic gas.
Claus process is conducted in two steps: thermal and catalytic.
In the first step, the H2S is partially oxidized with air though some H2S remains non-oxidized and in the second the remaining H2S reacts with the sulfur dioxide over a catalyst to make more sulfur.

Fault trumps evidence when
it comes to punishment
A new brain imaging study has identified the brain mechanisms that underlie our judgment of how severely a person who has harmed another should be punished.
Specifically, the study determined how the area of the brain that determines whether such an act was intentional or unintentional trumps the emotional urge to punish the person, however gruesome the harm may be, Phsyorg said.
"A fundamental aspect of the human experience is the desire to punish harmful acts, even when the victim is a perfect stranger. Equally important, however, is our ability to put the brakes on this impulse when we realize the harm was done unintentionally," said
"This study helps us begin to elucidate the neural circuitry that permits this type of regulation."
In the experiment, the brains of 30 volunteers (20 male, 10 female, average age 23 years) were imaged using functional MRI (fMRI) while they read a series of brief scenarios that described how the actions of a protagonist named John brought harm to either Steve or Mary.
