Scavengers are technological options used to reduce the H2S levels in natural gas, when the stream to be treated is less than 100 MMCFD with H2S concentration up to 100 ppm. Laboratory and field tests have been performed in order to determine the reaction capabilities of such chemical treatments. Then, to establish the effect of liquid water on the solid and liquid H2S scavengers performance, laboratory tests were carried out, using different H2O/H2S ratios. The results obtained from these tests, indicated that a ratio of 0.024 g H2O/g H2S did not affect the absorption capability of the liquid H2S scavenger. Besides, the solid H2S scavenger had three zones of absorption capacity, which were functions of water content.
