Abstract: The generation of hydrogen sulfide is very common in pharmaceutical industry due to the use of sulfer containing raw materials and fuels. However, ther removal of hydrogen sulfide from gaseous stream is highly essential due to the reasons health safety adn environment. Therefore, the industry is presently adopting physico-chemical methods for the removal of hydrogen sulfide from the gaseous streams. These methods are not only costly but also produces secondary pollutants, which needs to discharged appopriately. The industry alternatively can look at biotechnological methods of hydrogen sulfide removal, whcih are very competitive to the existing methods. The main advantage of these technologies is that less energy intensive and highly environmental friendly because the products formed in these processes can be easily utilizes elsewhere without any problems. The present paper reviews the three types of processes available with respect to the hydrogen sulfide removal from the gaseous streams emanaung from the pharma industry. The merits and application of the specific technology requires through understanding of the gaseous stream characteristics.
