可调谐二极管激光光谱仪

可调谐二极管激光光谱仪(TDLS)是一款激光气体分析仪,具备快速更新光学分析功能。TDLS支持在线提取,可以测量过程气体、燃气,进行杂质分析、传输监管和确保安全。

在化工、电力和炼油行业中,横河电机的TDLS技术在2012年EPRI研究报告和API556标准中被公认为是安全和环保燃烧应用所需的技术。

  • 横河电机的新TDLS™8000功能强大,将诸多先进工业特性集成于一台耐用设备中。其平台设计适用于现场测量,无需进行样品抽取和样品处理。

TruePeak可调谐二极管激光光谱仪发射激光通过待测气体,通过测量被吸收的激光量来分析气体浓度。由于传感器不接触工艺气体且无活动部件,使得平均无故障时间(MTBF)较长,从而降低了长期拥有成本(LTCO)。

火焰加热器是烃加工和发电等工业过程中的组成部分。加热器经过专门设计,使燃料和空气反应产生极高的气体温度,然后通过热交换器将能量传导给高度易燃的过程流体。火焰加热器消耗大量燃料,产生大量排放物,对人员和工厂构成潜在的安全隐患。

横河电机的TDLS分析仪有助于控制火焰加热器更准确、可靠地燃烧。在低过剩空气(LEA)级别使用火焰加热器时会带来可观的回报。在LEA燃烧控制中,消耗的燃料少,且可通过未使用的过剩空气冷却燃烧产物。

这些功效的成本利益相当可观,只要在燃料方面节省一个百分点,每年就可以节省数万甚至数十万美元。控制空气水平刚好超过不完全燃烧起始点,也可以实现“清洁燃烧”,帮助工厂满足环境排放要求。这尤其能够减少NOx的排放。

概述:

The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement. The TDLS200 Laser Analyzer is the solution to all these problems.

概述:

In maintaining and managing industrial plants, monitoring waste water pH/ORP is both a legal obligation and an unavoidable necessity for protecting the environment. Monitoring without an attentive eye can lead to severe consequences.

行业:
概述:

Considering safety and environmental issues such as combustion efficiency and decreasing NOX and CO in exhaust gas, it has become important to control O2 concentration in garbage incineration processes.

概述:

H2S management of exhaust gas in black liquor recovery boilers is required to meet an environmental regulations.

概述:

Cement is made by heating calcareous and argillaceous materials to a temperature between 1100 and 1500 °C. As this process uses massive amounts of energy, various energy saving measures are taken, including the measurement of oxygen concentrations in exhaust gases to control combustion. 

行业:
概述:

Reduction of air pollutant emissions is essential to protecting the environment and this is an issue that concerns all industries. Efforts are being made to reduce the emission of harmful substances from municipal refuse incinerators by measuring concentrations of components such as NOx, SO2, CO2, and CO in their exhaust gases.

概述:

Spectrometric technology can assess many critical characteristics about products, but it has limits. It can be challenging to determine when the line has been crossed

行业:
概述:

With fired heaters, users hope to get greater efficiency and reduced emissions but often are disappointed. Given the number of fired heaters operating every day and their importance in the process industries, any improvements realized across the board will have huge impacts. More units can reach their potential with some simple changes in work practices and technology upgrades.

概述:

In recent years, shale gas extraction technology has made rapid progress, inducing a shale gas revolution mainly in the USA. Thus, the need for analysis of hydrocarbon gases, including natural gas, is expected to grow rapidly. Traditionally gas chromatography has been used for the analysis of hydrocarbon gases; it can accurately measure the concentration of each hydrocarbon component in a sample of natural gas.

概述:

Combustion furnaces such as heating furnaces and boilers in plants include various sizes and types, and serve as energy sources, that is, they are cores in all production activities. Because a large amount of fuel such as gas or fuel oil is consumed in plants, their combustion efficiency directly affects the performance and running cost of the plants.
