In 2003, the "12.23" Chongqing blowout accident caused 243 deaths, more than 4,000 people were poisoned and sought medical treatment, and 100,000 people were evacuated overnight due to the lack of effective emergency rescue measures and cleaning methods, causing huge losses to people's lives and property
The death rate of hydrogen sulfide poisoning is high, and the accidents are often sudden and mass. Once a leakage accident occurs, it will seriously threaten the personal safety of the surrounding people and employees, and the impact of secondary disasters will be great, which will seriously pollute the nearby air and damage the ecological environment.
[0004] At present, the main method to deal with hydrogen sulfide leakage is ventilation and fire water spraying, but the threat of hydrogen sulfide still exists under this method, and a large amount of hydrogen sulfide-containing wastewater is produced
The patent application with application number 200910176521.1 discloses a hydrogen sulfide gas leakage scavenger, which uses diatomaceous earth as an inert carrier, resulting in many preparation steps

Abstract
The invention provides a hydrogen sulfide gas leakage arresting agent. The arresting agent comprises a powdery material which comprises an oxide and / or a carbide of magnesium and zinc, an aqueous material which comprises a strong alkali and / or a strong alkali salt, and a liquid material which comprises silicon oil and / or an aqueous organic solvent. Above components are added to water in sequence according to a ratio in the specification, are mixed and stirred to uniformity, and undergo a reaction to become a paste, and the paste is dried and is crushed into powder, wherein the addition sequence of the components is characterized in that: first the powdery material is added, then the aqueous material is added, and finally the liquid material is added. The hydrogen sulfide gas leakage arresting agent of the invention, which can be reacted with hydrogen sulfide in air, allows the concentration of hydrogen sulfide in air to be rapidly reduced and the dispersion of hydrogen sulfide and disaster generation to be prevented, and the hydrogen sulfide gas leakage arresting agent which adopts no inert carriers and has the advantages of simplified preparation step and simple preparation method is in favor of the production cost reduction and the application popularization.
Description
technical field [0001] The invention relates to a hydrogen sulfide leakage catching agent and a preparation method thereof. Background technique [0002] In the process of natural gas exploitation and petroleum refining in my country's petrochemical industry, high concentrations of hydrogen sulfide are often associated. For example, the content of hydrogen sulfide in natural gas reservoirs in Northeastern Sichuan is as high as 14%, and the risk of hydrogen sulfide leakage is high. [0003] Poisoning accidents caused by leakage of hydrogen sulfide gas frequently occur in the petrochemical industry. Hydrogen sulfide is a highly toxic, colorless (transparent), heavier-than-air gas. Low concentrations of hydrogen sulfide have an odor similar to rotten eggs. When the content is high, the olfactory nerves are quickly paralyzed, and it is odorless and difficult to detect. Inhalation of a small amount of high-concentration hydrogen sulfide can be fatal in a short time. In 2003, ...
