Beschreibung
Zusammenfassung:	The present invention discloses methods for inhibiting scale formation or precipitate formation in oil field flow lines and processing equipment exposed to fluid containing components that form scale or precipitates on surfaces of oil field flow lines and processing equipment, especially in highly paraffinic crude oils, where the method and system include applying an electric field across the fluid flowing through a flow line, where the fluid includes a scale or precipitate inhibitor and where the fluid strength and the inhibitor concentration is sufficient to reduce or prevent scale or precipitant formation. La présente invention concerne des procédés pour inhiber la formation de tartre ou la formation de précipité dans des conduites de circulation et l'équipement de traitement de champ de pétrole exposé à un fluide contenant des composants qui forment du tartre ou des précipités sur des surfaces de conduites de circulation et l'équipement de traitement de champ de pétrole, en particulier dans des pétroles bruts riches en paraffines, où le procédé et le système comprennent l'application d'un champ électrique de part et d'autre du fluide s'écoulant à travers une ligne de circulation, où le fluide comprend un inhibiteur de tartre ou de précipitation et où la résistance du fluide et la concentration d'inhibiteur sont suffisantes pour réduire ou prévenir la formation de tartre ou de précipité.
