Central district heating systems have gained attention in recent years because they can be more efficient than localized boiler units. The efficiency of district heating is usually due to power generation plants being able to produce heat and electricity simultaneously. District heating also helps prevent pollution by using advanced flue gas cleaning techniques.
A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO2 inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO2 to reduce the load on the equipment and improve the water quality.
Thermal imagers come in many different models and styles ranging from point-and-shoot cameras to those highly specialized for HD-level science and research applications. For some, choosing an IR camera may be cost driven, while others will look for specific hardware or software features. This white paper covers twelve considerations for buying an infrared camera, and offers a variety of options for diverse applications.
Maintaining generator temperature is critical to efficient power plant operation. Utility generators typically employ hydrogen to cool the generator, however many also use high purity water in addition to hydrogen. The Swan AMI Hydrogen analyzer provides a reliable monitor for measuring dissolved hydrogen in stator cooling water. The monitor comes complete with transmitter, flow cell, and sensor all pre-mounted on a durable stainless-steel panel for quick installation and startup.
Find all the analyzers you need for your water steam cycle. From the reliable and proven AMI Sodium P to the innovative AMI CACE EDI for cation conductivity, have options for your most pressing analytical needs.
Complete monitoring system for the automatic, continuous measurement of the conductivity before (specific / total conductivity) and after a cation exchanger with electro deionization (acid / cation conductivity). Calculation of the sample pH value and alkalizing reagent concentration based on differential conductivity measurement
The AMI CACE EDI re-invents the conductivity measurement with an attractive blend of reproducibility and performance, lowering resin consumption and significantly minimizing time and costs spent on maintenance. Without frequent resin changes required on typical Cation Conductivity instruments, the AMI CACE EDI delivers gap free trend analyses.
Both sodium and calcium sorbents have been used as dry sorbents for the mitigation of acid gas for the past 30 years with great success. “Calcium (lime based) sorbents vs. sodium (sorbents)” itemizes the fundamental differences, pros and cons between them, and the properties that make sodium bicarbonate and trona well suited for air pollution control.
n “Pre-SCR Injection of Sodium Sorbents,” presented at EUEC 2018, trona and sodium bicarbonate treatment of flue gas emissions are reviewed in two case studies. The first focuses on a power plant with a medium sized boiler.
The engineers at a municipal wastewater treatment utility were expanding their biogas digester system and were seeking an improvement over their existing, maintenance-intensive flow metering technology. They needed to measure the amount of gas contained within a gas bag as well as the flow rate of the gases traveling from the gas bag system into a co-generation power system.
