Project - Yanbu Power Plant - Cogeneration
Capacity: 512 MW A major utility company in Saudi Arabia contracted CMC Solutions to certify nine PEMS on combine cycle turbines that combust sales gas and light fuel oil. Eight of the turbines operate at 56 MW and one operates at 64MW. The PEMS were set to monitor SO2, NOx, O2, CO, and CO2 from the exhaust stack for all nine units. The equipment was installed and started up on April 2015. The ...

Experts in combustion control - Expert Paper
Fired heaters are integral to hydrocarbon processing (HP). Specifically designed for the reaction of fuel and air to produce extremely high gas temperatures, heaters transfer this energy to potentially highly flammable process fluids via heat exchangers. They consume large quantities of fuel, produce large quantities of emissions and are a potential safety hazard to personnel and plant. However, ...

Air Fuel Control System
Years ago, before exhaust emissions were a concern, the natural gas engines used mainly by the natural gas industry were designed to run with excess air. The air-fuel ratio controllers were mechanical devices that were not very accurate and sometimes not even used. These engines ran very well with 5% to 20% excess air. The air-fuel ratio would often vary with load and as long as the engines would ...

Performance, emission and combustion characteristics of DI diesel engine running on blends of calophyllum inophyllum linn oil (honne oil)/diesel fuel/kerosene
Kerosene (K)/diesel fuel (D)/honne oil (H) blends have a potential to improve the performance and emissions and to be alternatives to neat diesel fuel (ND) and has not been reported in the literature. Experiments have been conducted on DI diesel engine when fuelled with ND, H10 (10%H + 90%D, by volume) to H30, HK10 (10%H + 45%K + 45%D), HK20 (20%H + 40%K + 40%D) and HK30 (30%H + 35%K + 35%D). The ...

Low-Nox Burner retrofit Experiences in Cracking Furnaces at Dow, Terneuzen
Abstract: Dow Benelux B.V. (Dow) operates three ethylene plants from the Netherlands, all based within its Terneuzen facility. In 2009, Technip Stone & Webster Process Technology (Technip) studied options to reduce the NOx emissions from the cracking furnaces of cracker 1. The results of this study, combined with the experience elsewhere within the Dow Chemical Company, have been used to ...

Medium Combustion Plant Directive (MCPD): Monitoring of Emissions and Assessment of Compliance - Case Study
The Medium Combustion Plant Directive (MCPD) applies to over 140,000 plants in the EU, and regulates emissions from the combustion of fuels in plants with a rated thermal input between 1 and 50 MW. Part of the Clean Air Policy Package the MCPD also implements obligations arising from the Gothenburg Protocol under the UNECE Convention on Long-Range Transboundary Air Pollution. ...

Sokratherm compact CHP units with fully integrated SCR catalyst
For our compact CHP units with turbo engines we offer an emissions reduction solution with SCR catalyst fully integrated into the CHP unit’s sound absorbing case. It complies with all limit values of the German 44. BImSchV and and can already reliably reduce the NOx emissions below the limit value of 0,1 g/Nm³ which will be mandatory from 1.1.2025 on. The CHP units can be equipped with ...
