Ammonia (Solid State) Storage and Delivery System (ASDS)

Category: Diesel Engine Pollution Control Technology

Applicant: Faurecia China.

Description:

◎Solid state ammonia (NH3) storage system (ASDS) is ammonia generation system for on board selective catalytic reduction (SCR). This technology utilizes solid strontium chloride (SrCl2) to adsorb ammonia. The adsorbed ammonia is stored as solid state clathrate Sr(NH3)8Cl2. The adsorbed ammonia is released under certain conditions to convert NOX in the diesel exhaust to Nitrogen (N2) and water (H2O).

◎The ASDS uses strontium chloride (SrCl2) stored in sealed cartridges. Reverse reaction temperature of solid state clathrate (Sr(NH3)8Cl2) is 55~80 ℃ and ammonia will be released when the cartridge is heated.

◎Main components of ASDS include main cartridges, dosing control unit, control unit and sensors.

Environmental Features:

◎The ASDS has outstanding ammonia generation performance and de-NOx performance especially in low temperature condition. This the next generation de-NOx technology is capable to meet strict emission regulation.

◎Gaseous ammonia mix better with exhaust gas and require less arrangement for exhaust pipeline.

◎It's capable to generate ammonia and control NOX at cold start and low speed conditions.

◎There is no urea crystallization issue for the the ASDS system which improves de-NOX performance.

Financial Features:

◎Less engine temperature control requirements than urea system, better fuel economy.

◎Avoid urea crystallization issue, less maintenance cost.

Application Status:

Two buses with ASDS systems have run over 50,000km in Anting, Shanghai (Anting Line 2).

ASDS has been applied in public transport system in Suwon South Korea, London UK andCopenhagen Denmark. Over 300 city buses in Copenhagen are benefiting from ASDS system.

◎Uses proprietary abrasion and clogging resistant technology to ensure long-term, stable and efficient operation of the desulfurization tower.

◎Easy implementation allows a short construction period of about 20 days.

Environmental Features:

◎Improve flue gas SO2 removal rate. Tail gas SO2 concentration will be less than 30 mg/m3 after the process.

◎Keep environmental potential for the power plant those burning high sulfur coal.

Financial Features:

Construction investment varies depending on existing conditions, compared to traditional spray desulfurization methods, energy costs are reduced by 20% and construction costs are vastly lower.

Implementation status:

Part of project caseses: Huaneng Baotou No. 1 Thermal Power Plant 300MW Henan Yuneng Tongli Power Plant Generator 1 and 2 300MW Jiangsu Jiangyin Ligang Generator 5 660MW
