Abstract

En ny klasse svovelfangende eller -konverterende preparater omfatter diamin-terminerte, amin-aldehydaddukter, der adduktene i det vesentlige er bimolekylære amin-aldehydaddukter, og preparatet er i det vesentlige fritt for trimer og/eller triaziner. Det beskrives fremgangsmåter for å fremstille og å anvende den nye klasse av svovelfangende eller -konverterende preparater. Et diagram av ukentlig midlere vannproduksjon i m3 /dag mot produksjonsuker viser den fordelaktige effekt ved å benytte et slikt preparat etter optimalisering og justering av mengden basert på innhold av giftig svovel, og etter flerpunktsinjeksjon av preparatet i brønnfluider.
