FIELD: chemistry. ^ SUBSTANCE: method of determining content of water in petroleum products involves drawing a sample of the analysed petroleum product through a layer of water-coagulating material. The sample of the analysed petroleum product is then drawn through a layer of bulky water-absorbing material. Concentration of water in the petroleum product is then determined from the weight of water held in the water-absorbing material, for which a sample of the petroleum product which does not contain water is first passed through a layer of water-coagulating material and a layer of bulky water-absorbing material. The bulky water-absorbing material is then weighed and that weight is taken as the standard, and to determine content of water in the similar analysed petroleum product, the same bulky water-absorbing material with identical geometric dimensions is used and the sample has the same volume as the standard. After passing the sample of the analysed petroleum product through a layer of bulky water-absorbing material, the latter is weighed and the obtained weight is compared with the standard weight. ^ EFFECT: simple and accurate determination of the weight of water in an analysed petroleum product. ^ 2 cl, 1 dwg |
