simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

On-line flow injection solid sample introduction, leaching and potentiometric determination of fluoride in phosphate rock.

A flow injection method with on-line solid sample dissolution was developed for the determination of fluoride in phosphate rock. The fluoride was selectively leached (98-102.4 % recovery) from a 50-mg powdered phosphate rock sample with 0.50 M citric acid. Using the zone sampling technique the fluoride in the buffered leachate was determined by injecting 87 muL into the carrier stream using a f...

Flow injection photoinduced chemiluminescence determination of imazalil in water samples.

In this work, a fast, simple and economic method is proposed for the determination of imazalil in water samples by flow injection photoinduced chemiluminescence. In this method, imazalil degrades in basic media through the use of a photoreactor, and the resulting photofragments react with ferricyanide and generate the direct chemiluminescence signal. To the authors' knowledge, this is the first...

Flow injection chemiluminescence analysis for highly sensitive determination of noscapine

Noscapine is an antitussive drug and possesses potent antitumor activity. This work establishes a highly sensitive method for its determination by flow injection chemiluminescence (CL) technique. This method is based on its strong sensitizing effect on the weak CL reaction between sulfite and acidic permanganate. The mechanism for the sensitizing process is proposed on the basis of fluorescence...
