Corrosion inhibitors of the SNPKh brand. 2. The P,N-Containing corrosion inhibitor for protection of oil-field equipment

Protective effects of aryloxycarbonylmethylisoquinolinium chlorides on the iron surface were studied. The best results were obtained with decylphenoxycarbonylmethylisoquinolinium chloride (DPCMIQC) containing the alkyl C 10 in the aryl fragment. This salt was used as an active component in an SNPKh-type corrosion inhibitor. Experimental data for this inhibitor were compared with the results obtained in bench and commercial field tests in West Siberia and the Ural-Volga region.

“…If we marginally add corrosion inhibitor to the metal and medium interface, where corrosion is happening, it can effectively slow or prevent metal corrosion [1], it has the advantages of low cost, easy operation, quick effectiveness, long period, etc. Therefore, corrosion inhibitor act as a kind of economic, effective and practical metal corrosion protection technology, has frequently used in protection of oil and gas wells and gathering system.…”

CO2 corrosion is the main safety problem of production process in gathering, delivering and treating of oil and gas. Injecting inhibitors to suppress CO2 corrosion in oil and gas fields is an easy-to-use, low investment, quick solution method. The goal of this study is to summarize the already established research results of controlling CO2 corrosion, inhibition mechanism of CO2 corrosion inhibitors is reviewed, application status of inhibitor technology in CO2 corrosive environment is discussed. Research status of amides, imidazoline derivatives, quatemary ammonium salts and schiff bases overseas and domestic is highlighted. Finally, an outlook on the development trend of CO2 corrosion inhibitors is presented.
