1results about How to "Fast desulfurization" patented technology

This invention belongs to the field of petroleum extraction technology, specifically relating to a desulfurizing agent for oil wells and its preparation method. The preparation method includes: in an alkaline organic solvent, 1,4-bis(3-aminopropyl)piperazine and 1,3-dichloro-2-propanol undergo a first substitution reaction to obtain an intermediate; subsequently, the intermediate undergoes a second substitution reaction with 2-hydroxy-N,N-bis(2-aminoethyl)ethylamine to obtain the oil well desulfurizing agent. Based on 1 mole of 1,4-bis(3-aminopropyl)piperazine, the amounts of 1,3-dichloro-2-propanol and 2-hydroxy-N,N-bis(2-aminoethyl)ethylamine are 1.6-2.4 moles and 1.6-2.4 moles, respectively. The desulfurizing agent of this invention has the advantages of rapid desulfurization and good desulfurization effect, with a sulfur capacity of over 33%.
