2results 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%.

The utility model relates to exhaust treatment technical field, a kind of for treating waste gas's sulfur material scrubber, including washing tank, spraying component and air inlet component.Spraying component includes first liquid storage box and second liquid storage box, and the side wall of first liquid storage box towards second liquid storage box is equipped with several first spray head, and the side wall of second liquid storage box towards first liquid storage box is equipped with several second spray head.Air inlet component includes annular inlet pipe, and the upper of annular inlet pipe is equipped with first branch pipe and second branch pipe, and the first end of second branch pipe is connected with annular inlet pipe, and the second end of second branch pipe is inserted into washing tank, and located below spraying component.In the utility model, several first spray head and several second spray head are all arranged from top to bottom at equal intervals, when waste gas enters washing tank and moves upward, it will continue to contact and react with newly sprayed scrubbing liquid, the desulfurization effect of different positions in vertical direction remains balanced, and the overall desulfurization speed can be accelerated.
