SLB worked with the engineering contractor to quantify the amount of H2S that entered the headspace from the sour water. With the design basis established, a fixed-bed treatment system was custom designed, using a proprietary software model, and system performance predictions were provided. SLB also handled all communications with the various approved vendors. This integrated approach reduced both project costs and time, enabling delivery of the full package of equipment and product in a timely manner for commissioning the tanks. SULFATREAT 410CHP adsorbent is not only removing H2S effectively from the sour vent stream, it is also enabling more cost-effective operations with lower CO2 emissions compared with alternative solutions. The adsorbent bed life has surpassed estimates, enhancing operator satisfaction.
