Introduction
Light petroleum distillates and products mainly refers to solvent oil, gasoline
blending components, and finished gasoline and other substances; these
substances have low boiling point AND are easy to volatilize; AND the
aromatic hydrocarbons, benzene and olefins existed in such substances may
have an adverse effect on the health of the human body, the environment or
the stability of the product due to their own toxicity and Instability. Therefore, in
gasoline, solvent oil and other product standards, the benzene, aromatics and
olefin contents are often limited. In the production and processing links, for the
purpose of quality control, the manufacturer needs to make control analysis of
the hydrocarbon fraction in the petroleum fraction of the corresponding
distillation range. This standard test method is designed to establish a method
for the determination of hydrocarbon composition and benzene in light
petroleum distillates and products, to address the limitations or problems
existed in the current test methods.
Determination of hydrocarbon types and benzene in
light petroleum distillates and products -
Multidimensional gas chromatographic method
WARNING. This standard may involve certain hazardous materials,
operations and equipment, BUT does not advise on all safety issues
related to this. Therefore, the user shall establish appropriate safety and
protective measures before applying this standard AND determine the
applicability of the relevant regulatory restrictions.
1 Scope
This standard specifies the test methods of using multidimensional gas
chromatography technology for the determination of hydrocarbon composition
and benzene content in light petroleum distillates and products.
This standard is applicable to the determination of hydrocarbon composition
and benzene content in light petroleum distillates or products having a final
boiling point not more than 215 °C such as gasoline blending components,
solvent oils, gasoline products and the like. As for the concentration range of
determination, the volume fraction (OR mass fraction) of olefin is from 0.5% to
70%, the volume fraction (OR mass fraction) of aromatic hydrocarbon is 1% to
80%, AND the volume fraction (or mass fraction) of benzene is 0.2% to 10%.
This method is also applicable to the gasoline products processed from other
unconventional crude oils such as shale or oil sands or hydrocarbon fuels
synthesized from non-petroleum fossil fuels, such as Fischer-Tropsch
synthetic oils, provided that their boiling ranges comply with the requirements
of this standard. This method can only be used to determine the sample
exceeding the content range, BUT it cannot provide the precision data.
As for the gasoline for motor vehicles, in order to improve the performance of
gasoline products OR for other purposes, it often contains ether or alcohol
oxygen compounds, AND there may also be a variety of oxygen compounds
coexisted, in such case the ether compounds in the sample will produce peak
together with the olefin component, whilst the alcohol compounds will produce
peaks together with the C7+ aromatics component. As for the
oxygen-containing gasoline samples, after the relevant test methods (such as
SH/T 0663) are used to determine the type and content of the
oxygen-containing compounds, AND the procedures in Appendix A are
referred to make necessary corrections of the results of the hydrocarbon
composition, this standard is applicable.
This standard does not apply to the determination of monomer component
content in each hydrocarbon group except benzene.
C7+ Aromatics
The aromatic components in the light petroleum distillates or products
except for benzene, including monocyclic substituted aromatics, aromatic
olefins, and ring diene components greater than the six-membered ring.
3.5
Total aromatics or aromatic hydrocarbon
The sum of benzene (3.3) and C7+ aromatics (3.4).
3.6
Olefin traps
The column in the analytical systems which is used to selectively retain
olefinic components from mixtures of saturated hydrocarbons and olefins.
The column has a good reversibility for the capture and release of the olefin
component at a specific temperature, so it can be reused. Under certain
temperature, this column is capable of selectively retaining the olefin
component from the mixture of saturated hydrocarbons and olefins, AND let
the saturated hydrocarbon component pass through; AND the retained
olefin component is completely released after rising the temperature.
4 Method principles and summary
4.1 The analytical principles of using gas chromatography to determine the
hydrocarbon components and benzene content in light petroleum distillates
and products are as shown in Figure 1, AND the system and the column
connection diagram are as shown in Figure 2. After the sample enters the
chromatographic system, it first passes through the polar separation column
using a fixer of N, N-bis (α-cyanoethyl) formamide (shortly referred to as BCEF
column) to separate the aliphatic hydrocarbon component from the aromatic
hydrocarbon component. The olefin component in the aliphatic hydrocarbon
component consisting of saturated hydrocarbons and olefins is selectively
retained when it passes through the olefin trap, whilst the saturated
hydrocarbon component is passed through the olefin trap into the hydrogen
flame ionization detector (FID) for detection. After the saturated hydrocarbon
component is passed through the olefin trap, the benzene in the aromatic
hydrocarbon component has not yet reached the column end of the polar
separation column, AND the olefin trap is closed and temporarily disengaged
from the carrier gas f...
