Comprehensive measurement method of pollutants in diesel fuel

Abstract

The invention discloses a comprehensive measurement method of pollutants in diesel fuel, comprising the steps: removing solid precipitate and colloid via a film filter, and allowing the filtered diesel fuel to enter a closed container; allowing part of the diesel fuel in the closed container to be vacuumized via a steam generator, allowing obtained steam to enter a pressure analyzer for analysis, and leading the other part to an atomizer; atomizing the other part of the fuel diesel coming to the atomizer, and allowing the atomized diesel fuel to combust in a combustor; allowing emission from the combustion of the atomized diesel fuel to enter a gas analyzer for analysis; subjecting results to comprehensive comparative analysis and calculation. The comprehensive measurement method of pollutants in diesel fuel provided herein has the advantages that information about solid, liquid and composition can be acquired via filtering, steam and combustion, the measurement range is comprehensive, the content of pollutants can be calculated, and their types can also be speculated.

Description

technical field [0001] The invention relates to the field of oil product detection, in particular to a method for comprehensively measuring pollutants in diesel oil. Background technique [0002] Gasoline, kerosene, diesel, and lubricating oil are all related to oil products, and the quality of oil products is directly related to the use of vehicles in service or industrial and agricultural machinery and the emission of pollutants. There are many pollutants in oil products, mainly organic heterocyclic hydrocarbon derivatives, oxides or other non-oil component hydrocarbon derivatives containing N, S, and P; mainly including sulfides, nitrites, oxides And so on, as well as the moisture content index. Such impurity pollutants are likely to cause catalyst poisoning, incomplete fuel combustion, and mechanical failure caused by mechanical wear and tear. Compared with gasoline, diesel oil is heavy oil (about 10-22 carbon atoms), and its pollutants may not only have volatile compo...

AI Technical Summary

Problems solved by technology

Such impurities and pollutants are likely to cause catalyst poisoning, incomplete fuel combustion, and mechanical failure caused by mechanical wear and tear.

Compared with gasoline, diesel oil is heavy oil (about 10-22 carbon atoms), and its pollutants may not only have volatile components, but also high-boiling components, which are difficult to handle

[0003] At present, the determination methods of diesel pollutants mainly include instrumental analysis or post-extraction experiments, etc., because the components in diesel are relatively complex, which may easily lead to inaccurate measurement

However, the existing determination can only measure a certain component or a certain type of specific component, and cannot conduct a comprehensive and effective analysis of the components in the pollutants.
