When treating the sour gas, excessive use of scavenger is often seen because of the use of a quill as an injection. The purpose of this study is an investigation of the survival of the scavenger in the pipeline by nozzle injection. The scavenger requires a sufficient time to react with the gas and is therefore relevant due to particle survival. The primary part of this study is a CFD simulation of the $H_2S$ injection with a nozzle. Different injection direction is investigated to check the effectiveness of that. Furthermore, a change in the pipe design is investigated to see whether this has an influence on the particle survival.
The simulations showed that the large particles was not able to be carried from the flow, and therefore falls to the bottom of the pipe. While the small particles survives and got sufficient time to react with the H2S
