TDA Research has recently developed a new catalyst for the direct oxidation of hydrogen sulfide (H2S) to sulfur. As part of a project funded by Gas Research Institute, UNOCAL Corporation, Spirit Energy (a business unit of UNOCAL) will host a demonstration unit on one of their offshore platforms in the Gulf of Mexico. The expectation is that this direct oxidation process will economically decrease the quantity of H2S that is presently incinerated to S02 and emitted to the atmosphere and produce bright yellow sulfur.

Process Solution

UNOCALlSpirit Energy interest in the selection of TDA Research's catalyst for a direct oxidation process is based on the process' simplicity and its high recovery capability. Another advantage that this process has is its potential for high on-stream time...
