Demand for Effective Sulfur Purification Solutions

The increasing demand for efficient solutions for the collection and disposal of Dilute Non-Condensable Gases, (DNGC) has become more pronounced, especially with the EU's tightened regulations requiring industries to use the best available technology to reduce sulfur emissions into the air.

Addressing the Challenge of Controlling Sulfur Emissions in Industrial Processes

The concept of Dilute Non-Condensable Gases (DNGC) encompasses a mixture of various sulfur-containing compounds, including hydrogen sulfide, methyl mercaptan, dimethyl sulfide (DMS), and dimethyl disulfide (DMDS).

Industries dealing with chemicals, petrochemicals, pulp and paper, food manufacturing, and other processes where sulfur-containing substances occur as by-products face the challenge of safely and effectively managing these residual gases to meet strict legal requirements and environmental standards. With increasing awareness of environmental issues and the need to reduce air pollution emissions, interest in innovative solutions for sulfur-containing residual gas management has intensified.

Traditional methods for managing sulfur-containing residual gases include combustion and the use of chemical scrubbers or absorbers to remove sulfur gases from emissions. However, these methods are sometimes ineffective or insufficient to handle complex mixtures of sulfur-containing compounds.

To meet this challenge, companies and research institutions have begun developing and implementing innovative technologies to efficiently capture and treat sulfur-containing residual gases. This includes advanced processes such as the use of catalysts for gas purification, membrane-based separation techniques, and thermal oxidation to break down sulfur gases into less harmful compounds.

By investing in modern and efficient sulfur purification technologies, companies can not only comply with legal requirements and environmental standards but also reduce operating costs and improve their environmental performance. Additionally, the use of advanced sulfur purification technologies can contribute to increasing productivity and sustainability in industrial operations by reducing the risk of emissions and improving the working environment for personnel.

In this context, it is important for companies to collaborate with reliable suppliers and experts in the field of sulfur purification technology to identify and implement the most suitable and cost-effective solutions for their specific needs and processes. By doing so, companies can ensure compliance with legislation and environmental requirements while contributing to a cleaner and more sustainable environment.

DNGC mappings constitute a crucial part of environmental and production control within the pulp industry. These mappings aim to measure the flows and analyze the sulfur content in sulfur-containing residual gases generated during pulp production. Dilute Non-Condensable Gases, DNGC represents the total amount of reduced malodorous sulfur compounds formed as a by-product in the processes of pulp mills. These compounds include hydrogen sulfide, methyl mercaptan, dimethyl sulfide, and dimethyl disulfide, which are expressed as the sulfur content in the gas mixture.

At the core of DNGC mappings lies the need to quantify and monitor the emissions of these sulfur-containing compounds to comply with environmental legislation requirements and ensure that emission levels are within acceptable limits. Additionally, DNGC mappings also include analyses of diluted non-condensable malodorous gases, which encompass gases with DNGC content that are not strong malodorous gases. These may include gases from various sources such as tanks, wash filters, chip pockets, bleach filters, or dryers.

Furthermore, DNGC mappings also encompass analyses of gases emitted from tanks and landfill gases from landfills. These analyses aim to assess the content of methane and other gases generated in various processes within the pulp industry. By carefully monitoring these gases, the pulp industry can identify and take actions to reduce emissions, thereby improving both the efficiency of production processes and their environmental footprint.

In summary, DNGC mappings are a critical component of the sustainability strategy for the pulp industry, where meticulous measurements and analyses of sulfur-containing residual gases and other emissions contribute to maintaining environmental compliance and promoting responsible production.

Method, Instruments and Expertise

RISE utilizes gas chromatography (GC) as a key technology in research and development. GC is an advanced analytical method that separates and quantifies various chemicals in sample mixtures. It enables the identification of pollutants, quantification of substances, and characterization of complex mixtures. GC is employed in various fields such as the food industry for flavor analysis, the pharmaceutical industry for quality control, environmental science for monitoring air and water pollution, and materials science for analyzing material composition. By combining GC with mass spectrometry (GC-MS), RISE achieves high sensitivity and specificity for the identification and quantification of compounds in complex samples.

RISE also offers analytical services to industrial customers and partners by providing expertise in gas chromatography technology. This helps companies solve analytical challenges, optimize processes and products, and ensure quality and safety in their products and services.
