FIELD: process engineering.
SUBSTANCE: invention relates to monitoring of chemical additives in fluids extracted in oil industry and immiscible with water. Particularly, it relates to friendly process of monitoring of chemical additives in oil, condensate, exported oil, heavy oil, flows of hydrocarbons, diesel oil, lubricants, waxes, biofuel, diesel biofuel, oil products, other products of refining, purification and processing of oil and gas products including those containing minor amounts of water. Monitoring of water-soluble chemical additives in fluid immiscible with water that can or cannot contain some amount of water fluid. Claimed process exploits at least one reagent that outputs optically detectable product. Note here that detection step can be executed without separation of water phase with chemical reagents from fluid immiscible with water.
EFFECT: higher reliability and accelerated analysis.
