Many customers come to us and ask if we can send them some information about oil and gas recovery devices . We don't know what your parameters are, so we can't tell whether you need to purchase our equipment. So generally speaking, what parameters do we need to know to determine whether we can use VOCs equipment?
First, we need to clarify what kind of gas to recover
It is important to know the type of gas being recovered (such as methanol, acetone, dichloromethane, etc.). Different gases have different physical and chemical properties, which determine the recovery technology to be selected. If the gas is flammable, explosive, or corrosive (such as methanol, certain chlorides, etc.), special attention should be paid when selecting equipment.
For example:
Explosive gases: Explosion-proof equipment may be required. Ensure that all equipment, piping and instruments meet explosion-proof standards.
Corrosive gases: such as dichloromethane, may corrode materials such as stainless steel, so it is necessary to select materials with good corrosion resistance (such as special alloys, coating materials, etc.).
The second is our gas volume.
For example, 100 cubic meters per hour or 1,000 cubic meters per hour, we need to clarify the size of the gas air volume during recovery. The air volume refers to the gas flow rate per hour, usually in cubic meters per hour (m³/h). This is crucial to determine the size of the required equipment, processing capacity, and the selection of process flow.
If the air volume is small (such as 100 cubic meters per hour), small recovery equipment or modular equipment can be considered.
For large-volume gas recovery (e.g., more than 1,000 cubic meters per hour), it may be necessary to design larger-scale condensers, adsorption beds and other equipment, and the equipment's operating efficiency and energy consumption are also important factors to consider.
The last detail is the concentration. Concentration refers to the content of a specific gas in a mixed gas, usually in grams per cubic meter (g/m³) or percentage (%). The composition of a single detail is relatively simple. For a single gas, the recovery process is relatively direct, and the process design and recovery efficiency are also relatively easy to control. We only need to provide the number of grams per cubic meter.
If there are multiple mixed gases, you need to consider how to separate these gases first. Some gases may interfere with each other during the recovery process, resulting in reduced recovery efficiency. Therefore, it is best to choose a suitable separation or recovery method based on the characteristics of the gas. Too many gas components will affect our recovery efficiency. This is why as an vapor recovery manufacturer, we need to ask you many parameter data in detail. This is really for your consideration.
What are the main components of an associated gas recovery unit? Although new energy is the norm now, traditional energy has always been in use. Especially in China, which is a major oil importer, associated gas recovery units are relatively common. Many people wonder, what are the main components of an associated gas recovery unit? Are they the same as vapor recovery units ?
The main components of the oil associated gas recovery unit are:
Gas separator: A device used to separate oil, natural gas and water. Common devices include three-phase separators and two-phase separators.
Desulfurization device: removes hydrogen sulfide from associated gas through adsorption, absorption or chemical reaction to ensure gas quality.
Dehydration device: used to remove moisture from the gas to prevent moisture from corroding pipeline equipment.
Compressor: compresses the recovered associated gas for easy storage or transportation.
Gas tank: stores compressed gas for later use.
Gas utilization equipment: such as gas boilers, generators, etc., used to convert recovered gas into energy.
Obviously, the conclusion is still different. The actual device must be determined according to the on-site conditions. If you are interested, you can consult us for details. We have been specializing in vapor recovery for many years.
It is said that there is only one earth for mankind, and protecting the earth is what everyone should do. vapor recovery systems can not only improve the energy efficiency of the petroleum and chemical industries, but also bring significant benefits to environmental protection. The following are the main environmental benefits of vapor recovery: 1. Reduce Volatile Organic Compounds (VOCs) Emissions One of the main goals of vapor recovery is to reduce the emission of volatile organic compounds (VOCs). VOCs are atmospheric pollutants that can react with nitrogen oxides (NOx) in the air to generate ozone (O₃) and fine particulate matter (PM2.5), posing a threat to air quality and human health. The vapor recovery system can significantly reduce VOCs emissions by effectively capturing and recovering vapor volatilized during refueling and oil storage.
1. Environmental benefits: Improve air quality: reducing VOCs emissions helps reduce ozone generation, thereby improving the air quality in cities and industrial areas and reducing haze and ozone pollution levels.
Reduce harm to human health: VOCs (such as benzene, toluene, xylene, etc.) are toxic, and long-term exposure can cause health problems such as cancer and respiratory diseases. vapor recovery can effectively reduce the release of these harmful substances and protect the health of residents and workers.
2. Reduce Greenhouse Gas (GHG) Emissions During the vapor recovery process, vapor (such as natural gas and liquid petroleum gas) are captured and reused or converted into useful energy through a refining process, which helps reduce greenhouse gas emissions into the atmosphere due to vapor leakage, especially methane.
Environmental benefits: Mitigation of climate change: Reducing the emission of greenhouse gases (especially methane and carbon dioxide) can effectively slow down the process of global climate change.
Improve energy utilization efficiency: Recovered vapor can be reused, reducing energy waste and improving resource utilization efficiency.
3. Prevent soil and water pollution If vapor leak during storage and transportation, it will not only directly pollute the soil, but also affect the water source through groundwater infiltration. The vapor recovery system avoids the risk of oil contaminating the soil and water source from the source by reducing the occurrence of leakage.
Environmental benefits: Protect water resources: Reduce vapor leakage, prevent water pollution, and protect the quality of groundwater and surface water.
Maintaining soil health: Preventing petroleum products from leaking into the soil, thus avoiding soil contamination and its consequences, such as restricted plant growth and imbalanced ecosystems.
4. Reduce odor in the air vapor recovery can also effectively reduce the odor released by storage tanks, pipelines, gas pumps and other facilities. The volatile components of petroleum gas often have strong odors. Residents and workers who are exposed to these odors for a long time will feel uncomfortable, and these odors may spread to a wider area, affecting the surrounding living environment.
Environmental benefits: Improve the quality of the living environment: reduce the odor caused by vapor volatilization, making the surrounding residents and working environment more pleasant.
Reduce community complaints and health problems: Reducing odor emissions helps improve the quality of life in surrounding communities and reduces health problems caused by air pollution.
5. Save resources and promote sustainable development vapor recovery not only reduces harmful emissions, but also effectively recycles resources that would otherwise be lost. For example, by recovering volatile vapor, these resources can be converted into useful energy, or further purified and reprocessed in subsequent processes. This not only helps to improve energy efficiency, but also reduces dependence on fossil energy and promotes sustainable use of energy.
Environmental benefits: Resource recycling: Through the vapor recovery system, waste vapor are converted into reusable energy, reducing resource waste.
Supporting green energy transformation: The recycling process helps reduce the consumption of fossil energy, while providing practical experience and technical support for the future transition to cleaner, renewable energy.
6. Reduce the risk of fire and explosion. vapor are flammable and explosive during storage and transportation. If vapor leaks are not recovered in time, dangerous flammable gas mixtures may be formed, increasing the risk of fire or explosion. The vapor recovery system effectively controls and recovers leaked vapor, reducing the possibility of fire and explosion.
Environmental benefits: Improved safety: Reduce vapor leakage, reduce the risk of fire and explosion, and ensure the safety of the surrounding environment.
Reduce environmental disasters: Avoid large-scale environmental pollution and ecological disasters caused by fire and explosion.
The environmental benefits of vapor recovery facilities are very significant, mainly reflected in reducing air pollution, reducing greenhouse gas emissions, protecting water and soil resources, saving energy, and enhancing environmental safety. Through effective vapor recovery technology, we can promote a win-win situation between environmental protection and resource utilization, and make positive contributions to achieving sustainable development and addressing climate change. Therefore, it is indispensable. If the equipment is not used, it can easily cause greater pollution, and the gain outweighs the loss .
