Emerging from current COVID-19 related economic challenges, the global Tunable Diode Laser Analyzer (TDLA) market is expected to reach US$765 million by the year 2027, trailing a post COVID-19 CAGR of 8.7% over the analysis period 2020 through 2027. The current dual public health and economic crisis has complicated environmental compliance by creating operational and financial challenges for companies. With the pandemic being a lesson learnt on mismanagement of the environment, post COVID-19 the focus on the environment will become sharper as stricter amendments are made to environmental regulations. Application of tunable diode laser analyzers in emission monitoring and control is poised to get a healthy boost. The most polluting of the industries will emerge as attractive revenue spinners with companies coming under pressure to resume environmental obligations applicable to their operations. Widely employed in on-line gas analysis processes, tunable diode laser analyzers are advanced devices intended to measure concentration of gases with superior selectivity of different components. These devices identify chemical compositions of compounds as well as measure concentration of desirable elements without any contact. Tunable Diode Laser (TDL) is recognized as reliable technology for measuring trace gas components such as H2O, H2S, CO, NH3 & C2H2. Moisture (H2O), Carbon Dioxide (CO2), Hydrogen Sulfide (H2S), Ammonia (NH3), Acetylene (C2H2), Oxygen (O2). Tunable diode laser irradiates samples with light for measuring quantities of methane, carbon dioxide, water vapor and other gases in a mixture. Offering an ideal option to measure hazardous and corrosive gases, tunable diode laser analyzers use highly responsive and accurate measuring signals to support process control systems for enhanced safety, energy efficiency and productivity of industrial processes.

Sustained focus of environmental agencies such as the U.S. EPA on formulating new regulations and revising the existing rules favors growth in the tunable diode laser analyzers (TDLA) market. On August 13, 2020, the EPA announced two final rules revising and rolling back aspects of the VOC/methane New Source Performance Standards ( NSPS) pollution control standards. The new final rules are the 'Review Rule' or 'Policy Amendments' and the 'Reconsideration Rule' or 'Technical Amendments'. The 'Review Rule' entirely eliminates the standards for methane emissions, revised the 2016 and 2012 NSPS to remove storage and transmission segments from the category of sources regulated, and added new interpretations of the Clean Air Act that will have robust impact on the EPA's authority to regulate pollution. Similarly, the 'Reconsideration Rule' revises what is left of the 2012 and 2016 NSPS, adjusting requirements for pneumatic pumps, well completions, storage vessels, inspections, and fugitive emissions, among other things. EPA acknowledges that the revised rules would potentially lead to increased emissions of methane, VOC and HAP, and estimates that emissions to the tune of 850,000 short tons of more methane would be released by these sources during the current decade. Methane is a very powerful GHG and methane emissions from the oil & gas sector are likely significantly higher than previously reported, indicating these estimates may undercount the impacts of the rule.

Similarly in July 2020, the EPA proposed amendments to the 2013 National Emission Standards for Hazardous Air Pollutants (NESHAP) for Industrial, Commercial, and Institutional Boilers and Process Heaters. Boilers, the combustion devices intended to generate hot water or steam for on-site use in industrial operations, emit an array of air pollutants resulting in significant volumes of GHG emissions. The latest amendments aim to reduce toxic emissions from certain types of boiler units and illustrate the continued clean air progress made by the federal government. The rule, known as the Boiler MACT, seeks to establish emission standards for categories of boilers on the basis of the maximum achievable control technologies (MACT), with the objective to further reduce emissions of hazardous air pollutants from boiler operations. The amendments and revisions to environmental guidelines would encourage industrial entities to streamline their emission control strategies, while placing emphasis on various related technologies such as TDLA systems. Extractive gas analyzers are used in a large number of industrial processes to measure major gas concentrations to the smallest of trace contaminants. The extractive measurement technology extracts a partial gas flow from process and through a sample system, prepares it for analysis. Using various sensor technologies, the analyzer is able to distinguish a component and accurately measure its concentration. Determination of the concentration of gases in a process is used to control and monitor process flows, and is therefore decisive for the automation and optimization of processes and ensuring product quality. Extractive TDL analyzers offer accuracy, drift-free and reliable method for measurement of gas concentrations in a gas stream.
