Benzene levels tested after the degassing process = 0.4 ppm
Steam time reduced by 10 hours vs. the competitor’s product
The targeted level of tested benzene to achieve in the degassing process was less than 10 ppm benzene. During the shutdown, the plant planned on degassing this hydrotreater, but decided to try and steam out the surge drum on the hydrotreater unit using FQE™ LEL-V while steaming out the remainder of the hydrotreater plant with the previously used competitor’s chemistry. The surge drum was picked to test FQE LEL-V degassing chemistry because this was felt as the source of the worst benzene contamination.
