Procal´s analysers are used extensively in reporting and control applications in modern Biomass plants. The flexible and reliable instruments form the heart of the systems, enabling CO, NO2, NO, SO2, H2O, CO2, O2, dust and velocity to be measured.
The Procal 2000 emissions analyser is ideally suited to the harsh environments associated with Paper & Pulp Plants. The in situ, multi-component Continuous Emission Monitoring (CEM) system has an integrated auto-zero and calibration facility, thereby removing the need for intervention by maintenance staff under normal conditions.
Our Continuous Emission Monitoring (CEMS) DAS solution supports multiple emission regulation requirements and can work virtually anywhere in the world. We currently have a number of installations in North America and Middle East. Starting from Feb. 2014, after successful completion of the MCERTS certification process, the solution is offered in United Kingdom and other European countries. We are also interested in selling our products in Asia, South America and Australia regions.
Continuous Emissions Monitoring Systems (CEMS) are used to measure flue gases from stationary sources at a wide variety of regulated industrial facilities, including power plants, petroleum refineries, petrochemical plants, waste incinerators, pulp and paper producers, and many others. The types of air pollution measured from these sources vary widely based on the industry and process, and many are regulated by government agencies around the world.
Marine monitoring is a variant of OPSIS general offers for continuous emissions monitoring (CEM) and process control. The special operating conditions on-board vessels call for special measures to comply with regulations and expectations. However, OPSIS has mastered this environment and has for many years successfully delivered systems for marine applications.
With decades of industrial experience, our systems are designed and developed as a complete turnkey solution. From sample extraction, through analysis, data acquisition and report management, each system is configured to comply with the normative demands and technical constraints of our clients, specific to their industry.
OPSIS is a world-leading supplier of CEMS (continuous emissions monitoring systems) for various special applications in the industrial emissions sector. The OPSIS gas monitoring systems have been tested and approved by a range of international authorities, and has proven to have the best performance and longest calibration intervals. We specialise in the design and supply of high accuracy, low maintenance, cross-duct, non-extractive CEM systems. We also provide additional products and services, including dust and...
Testing the Performance of a DeNOx System Using a Portable Emissions Analyzer
Using Portable Emissions Analyzers to Measure the Performance of a NOx Reduction System in a Power Plant Boiler
The majority of power plants utilize NOx reduction systems (eg. Ammonia Injection, SCR, etc.) in their power boilers to ensure that the NOx emissions levels comply with current regulations. The frequent evaluation of the De-NOx system is fundamental to indentifying the adjustments necessary for an optimal and most cost efficient...
Nitric acid is manufactured from ammonia and is a key chemical in the manufacture of fertilizers. This is the main reason why nitric acid is produced in such large quantities. The production process of nitric acid produces nitrogen oxides (NOx), ammonia (NH3) and nitrous oxide N2O emissions.
Cement is the main ingredient of concrete, which is the most common building material in the world. Cement industry is one of the biggest CO2 emission producers mainly due to the huge production capacities and calcination process, which is an important part of cement production. Cement manufacturers need to monitor these emissions continuously according to local emission regulations. Read about our solutions to the cement industry!
Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective...
Raw gases are untreated flue gases that have not passed through an emissions control technology system like selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR). They are generally measured for the sakes of process control and warranty tracking. Typically only a few components are measured but fourier transform infrared spectroscopy FTIR technology allows the measurement of all components.
Waste-to-energy (WtE) or energy-from-waste (EfW) through incineration of waste is on the one hand an effective way of producing electricity and heat, while on the other hand it is disposing of possibly hazardous or unrecyclable waste. Its purpose is not to compete with waste recycling, reuse and prevention, but to complement them. After all, incineration not only reduces the amount of hazardous waste, but may also generate energy through the gases released in the process. Read about our solutions for waste-to-energ...
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions to the atmosphere. Read about our solutions for aluminum industry!
Power plants are industrial facilities used to generate electric power with the help of one or more generators which convert different energy sources into electric power. Power plants need to monitor emissions continuously according to local emission regulations. Read about our solutions for the power industry!
Fixed CEMS (Continuous Emissions Monitors) Measure at One Location
CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces.
If the CEM is measuring emissions that are higher than the regulated or permitted limits, it can be difficult to determine the source of the high emissions which could be from...
The accurate measurement of a gas mixture is essential to metal and mineral processing. Reliable measurements are needed to manage processes ranging from effective combustion control to optimized process control.
