How does triazine scavenger H2S?
One mole of triazine reacts with two moles of H2S to form dithiazine, the main byproduct. An intermediate product is formed, but rarely seen. Continued reaction can result in the formation of an insoluble trithiane product.
Which of the following is example of triazine?
A well known triazine is melamine (2,4,6-triamino-1,3,5-triazine).
What happens when H2S is oxidized?
Oxidation of H2S can lead to various products in which the sulfur can have oxidation numbers up to +6. The oxidation products include sulfate (SO42−), sulfite (SO32−), thiosulfate (S2O32−), persulfides (RSS−), organic (RSSnSR) and inorganic (HSSnS−) polysulfides, and elemental sulfur (Sn).
What is H2S scavenging?
H2S scavengers are widely used in hydrocarbon processing facilities to maintain plant worker’s safety and productivity and eliminate their odor emissions. These specialized chemicals react selectively with and remove H2S to help meet product and process specifications.
What is triazine used for?
Triazines are selective herbicides used to control a wide spectrum of grass and broadleaf weeds in cereal, oilseed, and horticultural crops. Triazine herbicides kill weeds by interfering with the electron transport chain in photosystem II (PS II).
What is MEA triazine?
MEA Triazine is the most commonly used chemical for applications requiring a non-regenerative hydrogen sulfide scavenger. It is used by the oil and gas industry to remove toxic and corrosive hydrogen sulfide from natural gas, refinery streams and olefins cracker products.
What are triazine anticonvulsants?
What are Triazine anticonvulsants? Triazine anticonvulsants act on presynaptic sodium channels and inhibit the release of excitatory neurotransmitters, glutamate and aspartate. Triazine anticonvulsants are used to treat absence seizures, partial seizures, tonic-clonic seizures and Lennox-Gastaut syndrome.
What is the oxidation state of H2S?
In the compound hydrogen sulfide, H2S , the two hydrogen atoms have an oxidation number of +1 , for a total of +2 . Therefore, the oxidation number of sulfur in the compound is -2 , and the sum of the oxidation numbers is 0 .
What kind of compound is H2S?
hydrogen sulfide
CHEBI:16136 – hydrogen sulfide
| ChEBI Name | hydrogen sulfide |
|---|---|
| Definition | A sulfur hydride consisting of a single sulfur atom bonded to two hydrogen atoms. A highly poisonous, flammable gas with a characteristic odour of rotten eggs, it is often produced by bacterial decomposition of organic matter in the absence of oxygen. |
What kills H2S?
Continuous Chlorination and Filtration Oxidation is the most common form of treatment used to eliminate hydrogen sulfide. In this process, a chemical is used to convert the dissolved hydrogen sulfide gas into forms of sulfur that can be easily filtered from the water.
What is unfused triazine ring?
Description The heterocyclic compound with an unfused triazine ring is primarily used for its herbicidal properties. The herbicide is used on a variety of weeds, such as dandelions, clover, and chickweed.
How do you make MEA triazine?
MEA-triazine is produced by mixing stoichiometrically equal amounts of monoethanolamine and formaldehyde. Three molecules of MEA plus three molecules of formaldehyde produced one MEA-triazine molecule and three molecules of water.
What do H 2s scavengers do for triazine?
Triazine hydrogen sulfide (H 2 S) scavengers consume H 2 S and form dithiazines by-products which are corrosion inhibitors.
What is the reaction between H2S and triazine?
One mole of triazine reacts with two moles of H2S to form dithiazine, the main byproduct. An intermediate product is formed, but rarely seen. The reaction is shown in Figure 3. The R-groups that are released during the two-step reaction vary by the supplier, and can be tailored for solubility.
When to use triazine for sweetening sour gas?
Triazine-based absorption is commercially used for sweetening sour gas when its H 2 S concentration is below a few hundred ppm ( Lozano, 2000 ). Here, we consider triazine-based absorption using flooded systems because they are designed to operate continuously and have lower capital expense (CAPEX) than batch systems ( Lozano, 2000 ).
How is triazine used in the gas industry?
Triazine has been used successful around the globe by many operators and facilities. It has been used in various other applications where control of low-concentration H2S is vital, including scale remediation and reservoir stimulation. It is commonly used with sour shale gas production in the US.
