manbetx官方石油炼油工业气相色谱

manbetx官方气相色谱发现在监测石油精炼和成品测试中发现了大规模应用。这是基于气相色谱法的几种专用技术的演化所证明的。manbetx官方

大规模炼油操作需要对过程参数的快速决策变更随着甚至一分钟的延迟可能导致巨大损失，因此可以使用在线分析轻松克服这些损失。这导致了在线分析仪的开发，如NGA，RGA，PIONA，直接碳氢化合物分析仪等。本文基于的可用选项提供了简介manbetx官方世界各地的炼油厂普遍分析工具的技术。

Common parameters monitored in petroleum industry

Ambient air as well as workspace monitoring for common gases such as \(CO_2, NOx,H_2S, CS_2\), benzene, toluene, xylene( BTX),etc
Analysis of underground and undersea hydrocarbon reservoirs for commercial viability of exploration of such resources
Refinery gases for optimisation of refining process
分析成品，如液化天然气，石脑油，汽油，航空燃料，瓦斯油，润滑剂，油脂，蜡，沥青等

石油化学分析通常需要高度复杂的混合物，导致数百个紧密间隔的峰值，这需要有效的分辨率能力。

The range of detectors which can be used are:

FID-炼油厂溪流中的轻质碳氢化合物

TCD –inorganic gases in ambient and work space environments

PID -analysis of BTX, unsaturated and aromatic compounds

FPD-organosulphur compounds in streams and oil residues

石油分析中的专用GC分析仪

已经开发了许多专用分析仪，其功能应在文章中短暂突出。

模拟蒸馏分析仪

模拟蒸馏是一种基于气相色谱的技术，用于基于其沸点（TBP）的沸点来模拟蒸馏塔中石油级分的分离。manbetx官方Simdis经常用于确定石油原油和精制产品的沸腾范围。沸点和产量型材用于操作决策，以提高产品产量和质量

SIMDIS分析的应用

Monitoring crude oil contamination – natural as well as intentional
Environmental sample analysis – Hydrocarbons in soil and water after extraction with solvents such as carbon disulphide
Characterisation of petroleum hydrocarbons in boiling range of naphtha, diesel , gasoline, etc

天然气分析

分析天然气主要是为

Physical parameters
BTU content
Hydrocarbon compositional analysis

GC Analysis of Natural Gas

BTU和化学成分分析都可以在可从配有毛细管柱，阀门和FID探测器的许多供应商可商购的改进的GC配置上进行。

BTU analysis is performed under isothermal conditions and composition analysis is performed under a temperature program

Columns are heated separately in separate ovens.

Hexane and heavier components such as heptane, octane, nonane are combined together to form a single peak C 6+

使用气瓶，锥体袋或通过直接管道进入管道或井口采样点来轻松引入样品。

Oven consists of several valves and column combinations which are controlled by the software program

炼油厂天然气分析

什么是炼油厂气体？

Refinery gas is a mixture of gases released during the fractional distillation of crude oil into various products of commercial use such as diesel, gasoline, fuel oil, kerosene, liquefied petroleum gas (LPG), lubricating oil, paraffin wax, bitumen and several petrochemicals

Gas chromatography analysis of refinery gases

Composition of refinery gas varies depending on the origin of crude oil.The usual components are methane, ethane, butane, butylenes, ethylene, hydrogen and hydrogen sulphide

传统系统在等温条件下通过阀门开关和双检测器使用多柱操作。使用氮作为载气和TCD检测在分子筛柱上检测氢气和氦气

剩余的碳氢化合物通过在第二TCD上使用氢载气来确定

Third column resolves components of intermediate boiling range, ethylene and ethane

[乳胶] O_2，N_2 [/乳胶]，甲烷和CO在第四栏中得到解决

Presently some configurations permit detection of all components using a single TCD using multi-valve multi-column options

Piona分析

使用GC的PIONA分析确定燃料中的烃基，主要是石蜡，异链烷烃，烯烃，环烷烃和芳烃。各个烃对汽油范围火花点火燃料的辛烷值（抗敲额定值）的影响深厚，这取决于所用内部压缩发动机的压缩比。石蜡降低辛烷值，而其他组件有助于改善它

基于Piona分析的GC

Conventional analysers were based on multi-dimensional GC using molecular sieve traps to selectively trap hydrocarbon groups

Modern GC – MS based systems offer several advantages such as

Shorter analysis time

Single capillary permits easy setup and ease of maintenance

Comparison with mass spectral library of standards
