Abstract
1. Способ определения маркеров транспортируемых нефти и нефтепродуктов, при котором летучие соединения (маркеры) экстрагируют потоком инертного газа путем барботажного контакта газового потока с раствором летучих маркеров в малолетучем растворителе (нефть или нефтепродукты) с последующим парофазным анализом методом газовой хроматографии, отличающийся тем, что в качестве летучих маркеров используют алифатические одноатомные спирты с числом углеродных атомов в молекулах от трех до пяти и более или их смеси, а поток инертного газа, насыщенные летучими соединениями (спиртовые маркеры и углеводороды нефти) барботируют через неполярный растворитель для удаления летучих углеводородов нефти и нефтепродуктов, затем поток инертного газа, насыщенный летучими спиртовыми маркерами барботируют через небольшой объем дистиллированной воды для получения концентрированного водного раствора спиртового маркера, который дозируют в испаритель газового хроматографа для анализа.2. Устройство для определения маркеров транспортируемых нефти и нефтепродуктов, содержащие последовательно соединенные блок подготовки инертного газа и три барботера, заполненные жидкими веществами, причем объем жидкости первого барботера превышает объем жидкости последующих, отличающееся тем, что первый барботер заполнен пробой нефти или нефтепродукта с летучим спиртовым маркером объемом V, второй барботер заполнен неполярным растворителем, например, н-деканом объемом V=V, а третий барботер заполнен дистиллированной водой объемом V=0,01V.1. The method of determining the markers of transported oil and oil products, in which volatile compounds (markers) are extracted with an inert gas stream by bubbling contact of the gas stream with a solution of volatile markers in a low-volatile solvent (oil or oil products), followed by vapor-phase analysis by gas chromatography, characterized in that aliphatic monohydric alcohols with the number of carbon atoms in the molecules from three to five or more or mixtures thereof are used as volatile markers, and the inert gas stream saturates volatile compounds (alcohol markers and oil hydrocarbons) are bubbled through a non-polar solvent to remove volatile hydrocarbons of oil and oil products, then an inert gas stream saturated with volatile alcohol markers is bubbled through a small volume of distilled water to obtain a concentrated aqueous solution of an alcohol marker, which is metered into a gas vaporizer chromatograph for analysis. 2. A device for determining markers of transported oil and oil products, containing a series-connected inert gas preparation unit and three bubblers filled with liquid substances, the volume of liquid of the first bubbler exceeding the volume of liquid of the subsequent ones, characterized in that the first bubbler is filled with a sample of oil or oil product with a volatile alcohol marker V, the second bubbler is filled with a non-polar solvent, for example, n-decane of volume V = V, and the third bubbler is filled with distilled water with a volume of V = 0.01V.
