Abstract

The invention discloses a desulfurizer, which is suitable for crude oil exploitation, gathering and transportation and treatment of sulfur-containing sewage. The desulfurizer is composed of the following components in mass percentage: 10-20% of N-methyl triethanolamine, 10-20% of ferric ammonium EDTA, 10-20% of hydroxyethyl hexahydro-s-triazine, and 1-2% of acetic acid , sodium acetate 0.1-0.2%, sodium nitrilotriacetate 0.1-0.2%, penetrant 1-2%, antifreeze agent 5-10%, defoamer 0.02-0.04%, and the balance is water. The desulfurizer provided by the invention uses ferric ammonium EDTA and hydroxyethyl hexahydro-s-triazine as main agents, and the s-triazine reacts with hydrogen sulfide to generate water-soluble sulfides to remove hydrogen sulfide through partial branched chain group substitution reaction. The reaction speed is fast, the reversible reaction is greatly reduced, the desulfurization efficiency is high at high temperature, and there is basically no reversible hydrogen sulfide release, thus getting rid of the use restriction and performance restriction of alcohol amine desulfurizers by temperature.

Description

technical field [0001] The invention relates to the high-efficiency treatment of hydrogen sulfide for safety considerations during the exploitation of hydrogen sulfide-containing crude oil at normal temperature, gathering and transportation, treatment of hydrogen sulfide-containing sewage, sulfur-containing natural gas, and sulfur-containing coalbed methane, especially a new type of weak alkaline anti-scaling type desulfurizer. Background technique [0002] Hydrogen sulfide is a colorless, highly toxic, acidic gas with a special smell of rotten eggs. Even low concentrations of hydrogen sulfide are highly irritating and toxic. In the process of crude oil extraction, gathering and transportation and treatment of sulfur-containing sewage containing hydrogen sulfide, due to the existence of hydrogen sulfide, not only corrosion, catalyst poisoning and damage to pipelines, instruments and equipment often occur, but hydrogen sulfide is highly toxic, Leakage can also pose a serious...
