Diesel Particulate Filter System

Category: Diesel Engine Pollution Control Technology

Applicant: Wuxi Weifu Lida Catalytic Converter Co., Ltd.

Description:

◎ Noble metal catalyst coating in DOC triggers oxidation reactions to oxidize HC, CO and a portion of particulate matters. The CDPF captures PM, where the PM is then burned by 1.) passive regeneration with the noble metal catalyst to help reduce temperature to 400℃, and 2.) active regeneration with diesel fuel injection to help reach higher temperature. The treated exhaust can satisfy the CN 5 emission standards.

◎ Installing the DPF fuel injection device will cause minimal changes to the engine, and the system can operate independently. Comprehensive and standardized calibration systems ensure DPF regeneration is quick, accurate, effective, and controlled so that the system can be re-used.

◎ The structure of the system is engineered so that the fogging coefficient UI≥0.95, raising the utilization rate of the catalyst and improving the system's ability to manage heat efficiency and reliability.

Environmental Effect:

Pollutant removal efficiency: CO>80%，PM>90%，PN>90%，HC>80%，NOx>90%.

Financial Impact:

System costs are varied and are based on different exhaust treatment requirements.

Application status:

This technology is in prototype stages, and the DPF system has not been commercialized yet.

Multi Functional Diesel Performance Additive

Category: Diesel Engine Pollution Control Technology

Applicant: Total Petroleum (Shanghai) Co., Ltd.

Description:

◎ Multi-functional diesel performance additive (AC700) is composed with an environmentally friendly, ash-free, phosphate-free and halogen free formula. The additive uses polyisobutylene succinimide as an oil-soluble surfactant.

◎ By clearing the carbon residue in the inner-engine to optimize combustion, the additive reduces the fuel consumption.

◎ Reduces CO, PM, HC and NOx emission that are caused by incomplete combustion

◎ The product is low-cost and fast-acting, thus produces visible results.

◎ The diesel fuel is required to meet Chinese 4/5 diesel fuel standard.

◎ AC700 is compatible with many materials used for combustion systems. It is compatible with stainless steel, aluminum, Teflon PFTE packaging coating, and any other materials that are compatible with C9/C10 aromatic solvents.

◎ The product is able to be operated and stored for more than 12 months, under temperatures that are above -10℃.

Environmental Effects:

◎ If added at high doses, AC700 could have significant effects on diesel fuel efficiency. Total has conducted chassis-dyno tests in Indian ICAT laboratory using typical Asian diesel fuel. Results revealed that AC700 improves cost efficiency by an average of 3.24%.

◎ Testing results revealed that the product can reduce emissions by up to1.8% for CO, 6.45% for HC, 5.56% for NOx , 1.93% for CO2 and 4.86% for PM.

Financial Impact:

RMB 40,000 / metric ton.

Application Status:

The product has approx. 10 major clients in the Yellow River Delta and Yangtze River Delta regions. The majority of the clients are within the petrochemical industry. Annual domestic sales have reached RMB 8M in worth.

Low Emission Control Technology for Valves

Category: VOCs Pollution Control Technology

Applicant: Garlock Sealing Technologies (Shanghai) Co.,Ltd.

Description:

◎ Low fugitive dust valves are formed with high-purity graphite fibers coated with INCONEL-special alloy string for extra strength.

◎ Maximum continuous working pressure: 10,000 psig (EVSP), Maximum continuous working temperature range: -200°C to 455°C.

◎ Packing material that is under pressure can experience shape deformation, which helps seal leaking areas on the valve stem. The seal has low resistance.

◎ After being tested under the U. S. API 622-Type Testing of Process Valve Packing for Fugitive Emissions, the product averaged a leaking capacity of< 100ppmv.

◎ Low density graphite can address the leaking problem from stems that have been stressed repeatedly. The product can be adjusted multiple times and can extend the valve's lifespan, EVSP can maintain minimal leaking capacity for long service life.

Environmental Effect:

Reduces VOC emissions and material costs that are caused by leaking.

Financial Impact:

Not provided.

Application Status:

The product is used in the United States, Canada and China. The company has approx. 50 clients in China, who are mostly in the chemicals, petroleum and nuclear power industries. The products made about RMB 8M in sales in China annually.

MayAir “Electric-Pocket” Technology

Category: Indoor Air Purification Technology

Applicant: MayAir Technology (China) Co., Ltd

Description:

◎ Can be used with any VRV or VRF air conditioning systems.

◎ Able to capture less than 0.01 microns of fine particles, and can be designed uniquely according to each client’s processes and needs.

◎ Electric-Pocket Technology can reach high PM filtering efficiency; it can also prevent fugitive dust even after shutting down the electric filter, or under strong wind conditions.

◎ The static electricity generator is built with pure metals, ensuring durability and up to 20 years of performance. The system can also be fully recycled.

◎ Can reduce the replacement frequency of the internal pocket filter, thus lowering the operation cost for the company.

◎ Compare to other medium filters, this filter creates relatively less resistance, and does not affect airflow and performance of the air conditioning system.

◎ Compare to other air conditioning systems with similar efficiencies, this system has relatively less energy demands and ozone emissions.

Environmental Effects:

◎ Lab testing results: PM2.5 reduction efficiency: 96%-98%, bacterial removal efficiency: >89%.

◎ On-site testing results (3 months after last maintenance): PM2.5 Removal efficiency: 96%.

Financial Impact:

Approx. RMB 3,000/per system (may be subject to change)

Application Status:

The product is currently deployed in the northern and eastern regions of China, mostly in high-end commercial buildings.
