Hydrogen Sulfide ScavengersHydrogen Sulfide Scavengers

Newpoint Gas has experience in all types of H2S scavengers including: liquids, solids, and catalyst. When picking the appropriate hydrogen sulfide scavenger, a wide variety of factors have to be taken into consideration, and each opportunity may require a completely different approach. Newpoint’s experience will ensure the best scavenger option has been chosen for the job.

Benefits of a Scavenger System for Sulfur Removal

  • Reduces H2S levels to less than 1 ppm
  • Safe
  • Environmentally friendly
  • Low capital requirement
  • No sulfur emissions

Factors to consider when choosing a H2S removal system

  • Gas pressure
  • Total H2S concentration
  • Electricity availability

Types of H2S Scavengers

  • H2S liquid scavengers
  • H2S catalyst scavengers
  • H2S solid scavengers


The primary concern in every project involving hydrogen sulfide is always safety. Utilizing an H2S scavenger in a facility designed by Newpoint chemically changes the deadly gas into a harmless compound that may be disposed of easily, safely, and in an environmentally sound manner. Batch treating for hydrogen sulfide reduces facility operations costs and eliminates the risks concerning H2S removal from natural gas.

With the many choices and high operating costs characterized by many technologies, companies are faced with the difficult choice of selecting the appropriate sulfur removal system and hydrogen sulfide scavenger. Newpoint can assist in making this choice based on our extensive experience.

History of H2S Scavengers

The use of H2S scavengers by the natural gas industry has seen significant growth, especially in situations where conventional amine treating is not economically feasible. For years, the Iron Sponge type processes were widely used by the industry to treat sour gas. Increased concerns of the environmental impact associated with the disposal of spent material and labor costs for replacement has increased the number of scavengers with better disposal properties.

Gas operators are developing reservoirs that have more and more hydrogen sulfide as part of the gas and oil. Hydrogen sulfide is a poisonous gas that is heavier than air. Hydrogen sulfide is very corrosive to well and surface equipment, can be a hazard in tanks that contain liquids, and must usually be at very low levels (less than 4 ppm) to meet sales specifications.

Hydrogen Sulfide Scavenger systems require a minimum amount of equipment to treat gas to pipeline specifications. Normally, two contactors are arranged in either a parallel or lead/lag flow arrangement. The lead/lag option will allow more efficient use of a scavenger and add flexibility in the scheduling of scavenger replacement.
