In the context of exhaust gas emission analysis for pharmaceutical and chemical enterprises, two key characteristics stand out. First, the emission process is often irregular due to the complex and variable nature of the production activities in these industries. Second, the volume of waste gas discharged can fluctuate significantly, making consistent treatment a challenge. To address these issues, this paper outlines effective treatment strategies aimed at helping pharmaceutical companies better manage their emissions.
The pharmaceutical industry is recognized as one of the major contributors to pollution in China. In response to the State Council's "Blue Sky Defense War" initiative, local governments and regulatory bodies have intensified environmental oversight. As a result, pharmaceutical companies are now facing stricter requirements for waste gas management. According to data from the Ministry of Environmental Protection, although the pharmaceutical industry contributes less than 3% to the national GDP, it accounts for approximately 6% of total pollution emissions, highlighting the urgency of addressing its environmental impact.
Despite growing awareness of environmental protection and improved regulatory enforcement, many pharmaceutical and chemical companies still struggle with proper waste gas management. Some have even been forced to shut down due to non-compliance with emission standards. This underscores the need for advanced and efficient treatment technologies that can meet both environmental and operational demands.
One such solution is the high-temperature plasma technology developed by Nanjing Yongyan Environmental Protection Technology Co., Ltd. This innovative approach offers a powerful and sustainable way to tackle industrial waste gas emissions.
When designing a treatment program, several key factors must be considered. These include the composition of the exhaust gas (such as the presence of moisture, solids, oil, or ease of handling), its concentration (high or low), and the discharge pattern (continuous or intermittent). Based on these parameters, an appropriate treatment method can be selected to ensure optimal performance.
High-temperature plasma incineration is particularly suitable for certain types of waste gas. It is ideal for gases with high organic content, complex chemical compositions, flammable or explosive substances (like butadiene), and those containing particulate matter, oil, or large volumes of continuous emissions. Industries such as gravure printing, offset printing, painting, chemical synthesis, petrochemicals, flavoring, and spice manufacturing benefit greatly from this technology.
To enhance the efficiency of the system, a secondary glass fiber filter is typically installed at the intake of the exhaust gas treatment equipment to control dust emissions effectively.
The high-temperature plasma incineration process involves applying a high-frequency (30KHz) and high-voltage (100,000 volts) power supply under controlled conditions. This causes the industrial waste gas to rapidly heat up to over 3,000°C within the reactor. Under the combined influence of extreme temperature and electrical potential, volatile organic compounds (VOCs) are ionized and completely decomposed into simpler substances like carbon, carbon dioxide, and water vapor.
This technology has several notable advantages. It achieves a removal rate of over 98% for harmful substances, meeting national emission standards. The system features a stainless steel, corrosion-resistant structure, ensuring long-term reliability and ease of maintenance. It also supports intelligent remote control, eliminating the need for constant on-site supervision.
Compared to traditional RTO (Regenerative Thermal Oxidizer) systems that rely on natural gas combustion, high-temperature plasma incineration offers superior performance. Traditional methods consume large amounts of natural gas, emit carbon monoxide and carbon dioxide, and are less energy-efficient. They also operate in an intermittent mode, which is not ideal for continuous waste gas streams.
Nanjing Yongyan was the first to introduce the concept of "high-temperature plasma incineration," holding an invention patent and being the only company worldwide with practical applications of this technology. This innovation has opened new possibilities for industrial waste gas treatment.
The advantages of high-temperature plasma incineration over traditional RTO methods include:
1. Continuous and uninterrupted operation, making it ideal for applications like waste incineration and gravure printing.
2. A broad range of applicability, capable of handling high-concentration, complex, flammable, and oily waste gases.
3. No reliance on natural gas, thus eliminating carbon emissions and reducing maintenance needs.
4. Lower energy consumption: while RTO systems may require 90 kW for a 20,000 m³/h flow, high-temperature plasma systems use just 46 kW.
5. High energy efficiency, with minimal temperature rise at the exhaust outlet.
6. Effective decomposition of difficult pollutants like dioxins, ensuring compliance with strict emission standards.
7. No ozone emissions, unlike some low-temperature plasma systems.
8. Cost-effective: high-temperature plasma equipment is less expensive and has lower operating costs compared to RTO systems.
In summary, high-temperature plasma incineration represents a cutting-edge, environmentally friendly, and economically viable solution for managing industrial waste gas emissions, especially in the pharmaceutical and chemical sectors.
