Foam can severely degrade the performance of a separator. Foaming in a separating vessel is a three-fold problem: 1. Foam has a large volume-to-weight ratio.
Our talented team of specialists here at Croda often write features for magazines and application specific journals on a wide variety of key industry topics. If you cannot find the article that you are looking for, or have a question in relation to an article that you have read then please contact us. To further assist the scientific understanding of asphaltene precipitation and therefore, chemical suppliers' ability to design efficient asphaltene inhibitors, a method has been developed and validated to study the effects of asphaltene inhibitors. Language: English Format: pdf Size: A study of wax control additives, evaluated by measuring the pour point and freeze point of solutions. We are working in partnership with University of Leeds to further develop our knowledge of crude oil flow.
Harford, Wilmingtom'DeL, assignorto E. Application October 29, ,. Borax has been employed successfully as a corrosion inhibitor for methanol and ethylene glycol antifreeze compositions. Synergistic combinations of borax and mercaptobenzothiazole have also been em-' ployed on a large commercial scale for the same purpose. Ethylene glycol antifreeze containing borax as a corrosion inhibitor requires an anti-foaming agent, as does ethylene glycol inhibited with other known commercial antifreeze corrosion inhibitors, where avoidance of foaming is important. The most common anti-foaming agent employed in ethylene glycol antifreeze compositionsare oily materials of low volatility.
Fluoroprotein Foam Fluoroprotein foams provide better control, greater fluidity, and superior resistance to fuel contamination in comparison to standard protein foams. Fluoroprotein foams are derived from protein foam concentrates to which small amounts of fluorochemical surfactants are added. The fluorochemical surfactants are similar to those developed for AFFF foam concentrates but used in much lower concentrations. All Rights Reserved.

foam in oil gas separators
DOI : The crude oils exploited in oilfields are mainly high-wax crude oils. Paraffins precipitate, crystallize, and form a three-dimensional network structure, when the temperature falls below the Wax Appearance Temperature WAT , which decreases crude oil fluidity. This poses huge challenges to oil exploitation and transportation, as well as cost control. To date, the addition of chemical pour point depressants has been a convenient and economical method to improve low-temperature fluidity in crude oils.

Research Progress and Discussion of Waxy Crude Pour Point Depressants: A Mini Review
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores ".
Bernard, George G. Laboratory experiments were conducted to determine the effect of foam on gas flow in porous media. Previous studies have indicated that foam may be applicable as a restrictive agent in influencing underground gas flow.

El anillo. Кольцо, - совсем близко прозвучал голос. Беккер поднял глаза и увидел наведенный на него ствол. Барабан повернулся. Он снова с силой пнул ногой педаль стартера. Пуля пролетела мимо в тот миг, когда маленький мотоцикл ожил и рванулся. Беккер изо всех сил цеплялся за жизнь.
Он застонал. - Джабба. Скорее вылезай. Он неохотно выполз из-под компьютера. - Побойся Бога, Мидж. Я же сказал тебе… - Но это была не Мидж. Джабба удивленно заморгал.
