Activated Alumina for Sulfur Recovery in Claus Prosess

Activited Alumina for sulfur recovery in Claus Prosess

Activated Alumina is a form of Aluminium Oxide that is very porous and

bonds with certain liquid and gases without its chemical or physical

form changing, Due to its high porosity, it has a high ratio of surface

area to weight, it is commonly used as a desiccant, for water

treatment, and as a catalyst in natura l gas and refining operations.

It can also adsorb other materials such as ars enic,fluoride,copper,and

lead,This ability makes it a suitable candidate for use in water

treatment operations. In many cases, it is more cost-effective than a

cutting-edge, large-scale water treatment facility. Activated alumina

water treatment is often the method of choice for rural areas and small

municipal facilities.

Activated alumina is manufactured from aluminium hydroxide by

dehydroxylating it in a way that produces a highly porous material;

this material can have a surface area significantly over 200 square

metres/g. The compound is used as a desiccant (to keep things dry by

absorbing water from the air) and as a filter of fluoride, ars enic and

seleniu m in drinking water. It is made of aluminium oxide (alumina;

Al2O3), the same chemical substance as sapphire and ruby (but without

the impurities that give those gems their color). It has a very high

surface-area-to-weight ratio, due to the many "tunnel like" pores that

it has.
