Abstract
Изобретение относится к области физико-химических методов анализа, в частности к инфракрасной спектроскопии определения состава смесей нефтепродуктов. Предлагается спектральный анализатор нефти, содержащий источник инфракрасного излучения, соединенный с источником питания, параболический рефлектор, пробоотборник, состоящий из двух плоскопараллельных пластин, с пробой нефтесодержащей смеси, коллиматор, соединенный с приемным концом волоконно-оптической сборки, состоящей из кварцевых волокон, при этом выходной конец волоконно-оптической сборки разделен на оптические каналы, имеющие равное количество волокон, причем по крайней мере один канал является опорным, концы оптических каналов через оптические фильтры связаны с фотоприемниками, на выходе которых получают электрический сигнал с получением его изображения на экране дисплея после компьютерной обработки, отличающийся тем, что конец волоконно-оптической сборки разделен на одиннадцать оптических каналов, соединенных с одиннадцатью фотоприемниками через одиннадцать оптических фильтров, соответственно, причем три оптических канала являются опорными, а волоконно-оптическая сборка дополнительно содержит волокна, выполненные из галогенида серебра, причем соотношение кварцевых волокон и волокон из галогенида серебра равно 1:2 и их общее количество составляет не менее 110, при этом две плоскопараллельные пластины пробоотборника выполнены из синтетического алмаза. Предлагаемый спектральный анализатор нефти позволяет определить количественное содержание серосодержащих соединений в нефтяной смеси в режиме поточного контроля за счет повышения чувствительности прибора.The invention relates to the field of physico-chemical methods of analysis, in particular to infrared spectroscopy for determining the composition of mixtures of petroleum products. A spectral oil analyzer is proposed that contains an infrared radiation source connected to a power source, a parabolic reflector, a sampler consisting of two plane-parallel plates, with an oily mixture sample, a collimator connected to the receiving end of a fiber optic assembly consisting of quartz fibers, while the output the end of the fiber-optic assembly is divided into optical channels having an equal number of fibers, at least one channel being a reference, the ends of the optical channels are connected through optical filters to photodetectors, the output of which receives an electrical signal to obtain its image on the display screen after computer processing characterized in that the end of the fiber-optic assembly is divided into eleven optical channels connected to eleven photodetectors through eleven optical filters, respectively, the three optical channels being reference, and the optical fiber assembly It contains fibers made of silver halide, and the ratio of quartz fibers to silver halide fibers is 1: 2 and their total amount is not less than 110, while two plane-parallel plates of the sampler are made of synthetic diamond. The proposed spectral oil analyzer allows you to determine the quantitative content of sulfur-containing compounds in the oil mixture in the flow control mode by increasing the sensitivity of the device.
