Although there are many sayings about the benefits of photovoltaic (PV), growing concern about its environmental-friendliness arises from its ongoing development trends. Studies have shown that “the probable environmental impacts of PV systems from manufacturing until disposal cannot be ignored. The production of hazardous contaminates, water resources pollution, and emissions of air pollutants during the manufacturing process, as well as the impact of PV installations on land use, are important environmental factors to consider.”
Therefore, proper management, design, and materials optimization will minimize the negative effects of its development. But the first step should lie in precise monitoring, which is for fostering a strong foundation for the following improvement. As a leading advanced monitoring equipment provider, FPI has provided well-tailored solutions worldwide. So let’s dive into one of its contributions to this industry.
Case Analysis -- JA Solar Viet Nam
JA Solar Viet Nam, located in Gwangju Industrial Zone, Bac Giang Province, Vietnam, houses a 1.5GW silicon wafer production plant whose production relies on photovoltaic power generation. To respond to the local calls to monitor and control gas emissions of silicon wafer production units, JA introduced an advanced flue gas monitoring system.
1. Project Difficulties
There is no one-for-all solution considering the different working environments. After a thorough communication with the director, we know that there are hiding some dampers:
Corrosion
The monitoring point of the project is located in the monocrystalline silicon acid-washing section, where the processed HCl acid fog will be emitted. The exhaust component is complicated, which is muddy and corrosive, and posting a challenge to the self-cleaning capability and corrosion resistance of monitors.
Nonstop working
2. How FPI Tackled the Problems
Corrosion
FPI provides in-situ laser gas analyzer which adopts tunable diode laser technology to analyze the concentration of the gaseous contaminants ,to prevent their damages to the pre-processing system. Besides,the construction materials also take this situation into consideration: its mounting flange material uses chromium, nickel, and molybdenum Austenitic stainless steel; outside the stack is the stronger bolster for mitigating the effect of chloride ion; the sensors that expose to the exhaust are made up of stainless steel coated with PTPE to protect the monitors from corrosive components and support its operation.
Nonstop working
Taking advantage of the advanced DLAS technologies, the LGA-4100 provided by FPI has better performance of zero drift, and span drift with higher stability. The purge air curtain protection of the optical system can reduce the workload of maintenance. The monthly and quarterly working span time meet the requirement of the local environmental protection department.
3. Site-Construction
Selecting the suitable spot
FPI’s Contribution
Devices that take part in this project include LGA-4100, TPF-100, and a customized data uploading system.
1. LGA-4100
The gas monitor adopts the world’s leading TDLAS technology, which will streamline the installation
and maintenance and increase reliability. It also has the following features:
In-situ measurement, quick response, extremely precise
Module and intelligent design to increase the handiness
The advanced technology will minimize the effect of the mixed gases to ensure the precision
2. TPF-100
The flue gas parameter unit is highly compact but houses three parameters: temperature, pressure, and flow rate. Multiple sizes are available for
different chimneys. Besides, it is rugged to resist toxic and corrosive foreign bodies.
