Flare Measurement 火炬测量 The Perfect Combination – Calorimeter and Process GC Continuous BTU for fast Fuel and Steam Control Speciation for fine Control and Quantification 完美组合—热值仪和过程气相色谱仪用于快速燃料和蒸汽控制的连续 BTU精细控制和定量的形态
The objective of the refinery sector rule or the upcoming olefinand chemical sector rule is to satisfy the regulatory requirementswith high certainty, lowest cost and a simple and maintainablemeasurement system. Flare monitoring needs the speed tocontrol the heat value for maximum combustion efficiencyand to control auxiliary steam to minimize flare visibility. Acalorimeter provides that speed but lacks the desirablespeciation. A Process Gas Chromatograph (GC) provides thespeciation to fine tune waste gas composition dependent steamaddition, prevents over steaming, locates waste gas source andquantifies emission.Either technology alone could satisfy the regulatory requirementsbut does not provide the most reliable and best control scheme.The winning combination are both together. Over many yearsand hundreds of analyzers installed on flares, the relativelysimple, long-term repeatable and reliable measurement systemshave been proven successfully. By backing up each other,uninterrupted control and data availability is provided. Knowntechnologies, often with on-site know-how available ensuresindependent and quick maintainability. A winning combination!
炼油行业规则或即将出台的烯烃和化工行业规则的目标是以高确定性、最低成本和简单且可维护的测量系统满足监管要求。火炬监控需要快速来控制热值以获得最大燃烧效率并控制辅助蒸汽以最小化火炬能见度。热值仪提供了这种速度,但缺乏理想的形态。过程气相色谱仪 (GC) 提供形态以微调依赖于蒸汽添加的废气成分,防止过度汽化,定位废气源并量化排放。单独的任何一种技术都可以满足监管要求,但不能提供最可靠和最佳的控制方案。获胜组合两者都在一起。多年来,数百台分析仪安装在火炬上,相对简单、长期可重复和可靠的测量系统已被成功证明。通过相互备用,提供不间断的控制和数据可用性。已知技术,通常具有可用的现场专有技术,可确保独立且快速的可维护性。这是一个成功的组合!
