Figure 2. Elemental sulfur accumulating as a result of acid gas processing at the Zama Gas Plant in Alberta, Canada. As part of NETL’s Regional Carbon Sequestration Partnership (RCSP) Validation Phase effort, the Zama Gas Plant is capturing and sequestering a co-contaminant stream of carbon dioxide and hydrogen sulfide (H2S) for enhanced oil production purposes. Co-sequestration reduces the accumulation of and treatment costs for elemental sulfur for the Zama Gas Plant. While not an electric generating facility, the RCSP Validation Phase efforts at the Zama Plant are a good example of co-sequestration capture and subsequent geologic storage.
