  1. HYDROGEN SULFIDE (H2S) SCAVENGERS                


Catena´s technology team has developed a large variety of high performance H2S scavengers for different applications

Following are some examples:

 a)      CATENA GS-1A

An oil soluble H2S scavenger used mainly in treating sour oil and gas systems,

CATENA GS-1A is chemically and physically compatible with oil and gas treating chemicals, such as demulsifiers, defoamers and corrosion inhibitors.

The product features immediate reaction with hydrogen sulfide and is very effective even at low dosage rates.

b)      CATENA GS-3W

A water soluble H2S scavenger, CATENA GS-3W neutralizes hydrogen sulfide and its ions HS- and S= through a unique oxidizing reaction producing atomic sulfur (So). CATENA GS-3W is recommended for use in high BSW production systems, produced water treating systems, disposal water treating stations and other applications where high amounts of sour aqueous streams are treated against H2S, including sour oily waters.

 c)       CATENA GS-5GW

The most recent development of CATENA´s Research and Development Laboratories, this H2S scavenger is designed specifically to work both in sour gas and sour aqueous systems. This product outcasts from the other ones in the market where environmental, safety and health issues are a concern in addition to the requisite for high efficiency, especially on offshore installations, where storage space for chemicals is limited and HSE care are of extreme importance.

Its exclusive formulation was developed in order to give CATENA GS-5GW a number of unparalleled features, like:

  • High performance with reduced amount of chemical;
  • Unbeatable cost performance;
  • Biodegradability. In addition to being biodegradable, CATENA GS-5GW is totally HSE friendly. The product is completely safe for the health of workers and to the environment;
  • In sour water or high BSW systems, the product can be used through continuous injection or batch treatment; for sour gas systems, the CATENA GS-5GW can be used in continuous injection or in gas washing towers.
