Evolving Measurement Demands in the Global Biogas and Biomethane Industry

Global biogas and biomethane production are expanding rapidly, shifting industry priorities from project deployment to efficient operation, accountability, and long-term reliability.

Europe remains one of the most advanced regions in the biomethane sector, operating more than 1,600 production plants with a combined annual capacity of approximately 7 billion m³. The region has also est

The Background: Accurate Atmosphere Control Is Critical in Gas Carburizing

Carburizing is a widely used thermochemical surface treatment method that adds carbon to the surface of low-carbon steels, enhancing hardness and wear resistance while preserving core toughness. Among different carburizing methods, including solid, liquid, and gas-based processes, gas carburizing has become the mainstream solution in modern heat treatment due to its advantages in atmosphere unif

Global Regulatory Landscape: Tightening Gas Turbine Emission Standards

As decarbonization accelerates worldwide, emission standards for gas turbines are tightening across global markets. In the United States, the Environmental Protection Agency (EPA) proposed stricter nitrogen oxides (NOx) limits in late 2024 under the Clean Air Act’s New Source Performance Standards (NSPS), targeting new and modified fossil fuel-fired combustion turbines.

In Europe, the r

The Background: Challenges in Gas Nitriding Process

Nitriding is an advanced steel surface treatment that introduces nitrogen atoms into steel surfaces at controlled temperatures, creating a high-hardness, wear-resistant surface layer while preserving core material toughness. Among gas, liquid, and plasma (ionic) methods, gas nitriding offers distinct advantages: precise temperature control, excellent coverage of complex geometries, and consistent case depth formation.

Biogas production involves the anaerobic digestion of organic materials, such as agricultural waste, food scraps, and sewage. This process occurs in a sealed environment where microorganisms break down the organic matter, producing biogas primarily composed of methane (CH4) and carbon dioxide (CO2), with small amounts of other gases like hydrogen sulfide (H2S) and Oxygen(O2).

The process can be broken down into the following steps:

Production: Organic waste is p

In industrial applications, flare systems are critical safety devices designed to safely burn off excess gases. Whether in refineries, chemical plants, or oil & gas facilities, flare systems help maintain pressure relief during emergency conditions and prevent the release of toxic gases into the atmosphere. Monitoring the composition of flare gases in real-time is crucial to ensuring safety, regulatory compliance, and operational efficiency.

Traditional gas analysis methods often r

In the steel production industry, maintaining the safety and efficiency of coke ovens is crucial. Coke, a key material in steel production, is manufactured by heating coal in oxygen-deficient environments, resulting in the release of syngas, which contains combustible gases such as H₂, CH₄, and CO. These combustible gases can pose a significant explosion risk if the oxygen concentration reaches certain levels. According to the Safety Data Sheet from United States Steel, the explosion limi

Vietnam is implementing a progressive regulatory framework to control emissions from new motorcycles entering the market. Decision 19/2024/QD-TTg, effective January 1, 2025, establishes an ambitious roadmap aligning with European standards. The regulation mandates Euro 2 and Euro 3 equivalent standards from January 2025, advancing to Euro 4 by 2026-2027 for two-wheeled motorcycles, while introducing a zero-emissions standard for three-wheeled motorcycles by January 2026.

Vietnam'

Vietnam is approaching a significant regulatory milestone with the implementation of comprehensive motorcycle emissions inspection requirements. The Law No. 36/2024/QH15 on Road Traffic Order and Safety and Circular 47/2024/TT-BGTVT, taking effect on January 1, 2025, will mandate emissions testing for all motorcycles over five years old. Testing intervals will vary based on vehicle age—with inspections required every 24 months for motorcycles 5-12 years old and annual inspections for those

In the realm of gas analysis, Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology stands as a cornerstone innovation, distinguished by its exceptional precision, sensitivity, and reliability. At its core, TDLAS technology harnesses the unique properties of semiconductor lasers - specifically their narrow linewidth and tunability - to perform highly selective molecular gas analysis. The process begins with laser frequency modulation through semiconductor laser curre
