Ion chromatograph can be used to simultaneously determine various anions and iodine ions in the petroleum water, which is convenient and fast.
In order to avoid the interference of a large number of chloride ions in oilfield water with the determination of formic acid, acetic acid and propionic acid, four ions can be determined simultaneously by ion chromatography.
Chloride in coal tar is divided into inorganic chlorides and organic chlorides. Sodium chloride in inorganic chlorides is not easy to be hydrolyzed, but magnesium chloride and calcium chloride are very easy to be hydrolyzed by heat. Their hydrolysis temperatures are 120℃ and 175℃ respectively. After…
In recent years, petroleum has grown rapidly, and the types of petroleum processed by refineries have become increasingly complex. The various salts contained in petroleum are not only prone to scaling in furnace tubes and heat exchangers during the processing, but also cause corrosion and catalyst …
