Specialty chemical delivering a safe and stable H2S byproduct
SULFATREAT HP is a non-hazardous granular material used in the removal of hydrogen sulfide (H2S) from natural gas streams. SULFATREAT HP is applied through a batch-processing treatment. It has improved reaction characteristics and also removes methyl and ethyl mercaptans.
SULFATREAT HP is solid, unlike nearly all other scavengers which are liquids, and therefore prevents foaming or carryover. Its reactions are predictable and reliable under a wide range of conditions.
Applications
SULFATREAT HP is used to pack one or more vertical pressure vessels having a downward gas flow. During the scavenging process, gas or vapor flows through the consistently sized and shaped, granular SULFATREAT HP in the vessel’s bed. This creates a chemical reaction with hydrogen sulfide to form a stable and safe byproduct.
The advantage to using SULFATREAT products is that product consumption depends only on the amount of hydrogen sulfide that actually passes through the bed. This economically matches the need for H2S removal with variations in system flow conditions and outlet specifications, regardless of the total volume or other common components of the gas.
Just upstream of the SULFATREAT vessel(s), the installation requires a small inlet separator to remove excess liquids from the gas. Equipment may also include a water-spray system to saturate the inlet gas.
