Advanced 'in situ' continuous monitoring of Mercury Emissions

汞是一种剧毒的自然存在的金属，对人类和生态系统健康都会造成重大损害。汞排放来自一系列工业过程，特别是大规模燃烧。这类工业越来越需要探测和测量释放到大气中的气体物质中的汞。汞是出了名的难以探测和测量的元素。在过去的20年里，已经实施了许多技术。其中一些是商业化的分析产品；目前的汞分析仪存在尺寸、复杂性、成本、测量不完整和坚固性等问题。ProTea Limited以前曾在其用于“标准”气体的烟道气分析仪系列中开发过紫外线(UV)分析仪。该项目旨在进一步开发这项技术，并将其应用于汞，其优势是提供连续的总汞原位分析。它将克服目前需要从烟囱或烟囱中移走样本的不足。它还将提供连续的数据，以便操作员进行干预，并编制监测排放的记录。环境效益是这项技术所能做的事情的核心，也是Protea已经工作了20年的领域。使环境气体监测变得简单和准确将使希望了解和控制其排放的工业运营商受益。ProTea Limited是一家总部位于英国的中小企业，正在开发大量的出口销售，该项目将进一步促进英国的国际贸易。

Mercury is a highly toxic, naturally occurring metal that causes significant harm to both human and ecosystem health. Mercury emissions come from a range of industrial processes, notably large scale combustion. Such industries have an ever growing need to detect and measure Mercury amongst the gaseous substance being released to atmosphere.Mercury is a notoriously difficult element to detect and measure. There are a number of technologies that have been implemented over the last 20 years. Some of these are commercially available as analytical products; current mercury analysers suffer from issues of size, complexity, cost, incomplete measurements and robustness.Protea Limited has previously developed Ultraviolet (UV) analysers in its range of stack gas analysers for "standard" gases. This project aims to further develop this technology and apply it to mercury, with the advantage of offering in-situ analysis of total mercury on a continuous basis. It will overcome the existing shortfall of samples being required to be removed from a stack or chimney. It will also provide continuous data to allow operator intervention, and compile records for monitoring emissions.Environmental benefits are at the heart of what this technology can do and the field that Protea has been working in for 20 years. Making environmental gas monitoring simple and accurate will benefit industrial operators looking to looking to understand and control their emissions.Protea Limited is a UK based SME who are developing significant export sales and this project will further boost international trade for the UK.
