Ensuring the safe and efficient operation of energy plants requires regular and meticulous inspection, cleaning, and maintenance activities to meet technical requirements.

Industrial maintenance and cleaning are routine activities conducted annually at hydroelectric and thermal power plants, including specific tasks such as:

• Cleaning, maintenance, inspection, testing, and calibration of plant equipment systems.
• Addressing and rectifying operational defects as they occur.
• Repairing, adjusting, or replacing equipment that does not meet technical specifications.

Management departments at production plants must devise cohesive and effective solutions to successfully fulfill these tasks, ensuring safe and productive operations.

How to optimize cleaning costs and effectiveness in industrial cleaning at plants?

Some hydroelectric and thermal power plants still rely on traditional cleaning materials such as rags, leftover fabric, or scraps, which are unable to completely absorb industrial oils and chemicals, thus leaving residues on surfaces. Additionally, these materials cannot be reused after handling spills. Therefore, implementing innovative methods in maintenance and cleaning processes at plants to optimize efficiency and costs is essential.

Across large-scale production plants and industrial zones worldwide, the utilization of advanced technology products for thorough cleaning is increasingly prevalent. Specialized products ensure optimal cleaning for all surfaces while saving labor and resources. Commonly used materials provided by BIGNANOTECH for machinery and production areas include:

• Oil Absorbent Pad: Swift and efficient cleaning of oil spills both on land and underwater, selectively absorbing oil without absorbing water.
• Oil Absorbent Pillow: Ideal for placing in areas with continuous oil leaks, with a high capacity to absorb large amounts of oil.
• Oil Absorbent Sock/Boom: Prevents oil spills from spreading into the surrounding environment during large-scale spills, aiding in effective containment and response.
• Oil Absorbent Powder: Completely removes liquid residues like sticky oil from hard surfaces without requiring secondary cleaning agents.
• Biological Oil-Degrading Powder: Decomposes oil contaminants in soil and transforms them into organic fertilizers beneficial for soil.
• Oil Filter Fabric: Helps separate oil and impurities from water, ensuring the safety of discharged water into the environment.

In Vietnam, Big Nano Technology is the sole company specializing in manufacturing specialized materials for industrial cleaning of oil and industrial chemicals. The company provides the most efficient and optimal solutions for industrial cleaning during plant operations, industrial zones, and handling oil/chemical spills across diverse environments. With exclusive advanced Nano technology from Japanese experts, BIGNANOTECH products offer rapid absorption and optimal retention capacity, delivering superior cleaning efficiency and cost savings compared to conventional methods.

In recent years, all countries around the world have been very concerned about the effects of pollutants on human health, the living environment in general and especially water pollution. and oceans on the earth’s surface. The cause of this pollution is largely due to humans using chemicals and fuels from many different sources, especially petroleum. Although the use value of petroleum is great, due to its dangerous nature (flammable and explosive, highly polluted). Every year we still have to witness many accidents from oil ships causing millions of tons of oil to spill into the sea, causing huge consequences for the earth’s marine resources and environment.

Stemming from that urgency and based on the results of a number of domestic and foreign studies, a number of effective and highly feasible solutions have been proposed to handle oil spills that pollute the environment. sea market from today’s oil tankers. At the same time, limit negative impacts on marine resources and environment caused by maritime activities.

1. Overview of marine pollution due to oil

Basic causes of oil pollution

The main cause is due to tanker accidents and daily operations from oil tankers. Research results show that every year in the world, about 3.5 million tons of oil from all sources are dumped into the sea, of which 400,000 tons are due to accidents at sea, 700,000 tons are due to magnetic manipulation. oil tankers, 300,000 tons due to the dumping of ballast water mixed with oil and 50,000 tons due to the operation of bringing the ship to the repair dock.

Effects of oil pollution on the environment and marine ecosystem

Through many studies and statistics, it has been shown that oil pollution has a serious impact on plankton, seaweed, mangrove forests, aquatic systems, and tourism and recreational activities. ..

2. Basic solutions are often applied to handle oil spills

Use buoys to prevent oil on the water surface

An oil buoy is a type of buoy used to collect and contain oil spills. For ships in the early stages of oil spilling into the sea, buoys will surround the ship, control and narrow the spread of oil on the water surface, and collect oil in a fixed area for ease of evacuation. Pick up and process with the highest efficiency. The oil containment buoy has a buoy body in addition to an anchor rope and connecting plate connecting the buoy sections together.

For example: B620 oil-absorbing crank buoy is manufactured in Vietnam

• Float body: 20 centimeters in diameter, 6 meters long, made from nanotechnology with superior absorbency
• The product is highly durable, resistant to oxidation and seawater corrosion.
• Joint: made of aluminum alloy that can extend the floats together

Because the important function of the oil containment float is to prevent collection and redirect oil away from sensitive areas. Therefore it needs to be flexible to accommodate the movement of the waves, and at the same time have the right flexibility to retain the oil. Therefore, when designing or purchasing oil containment buoys, it is necessary to pay attention to a number of issues such as how to structure them for easy transportation and storage, and have specific characteristics to withstand waves and effectively prevent oil. best. To deal with spills that may occur on Vietnamese oil tankers today, there must be a prepared number of oil containment buoys to suit the actual conditions of each ship. According to data from some Asian countries, they have reserved their oil buoys based on the total amount of oil exported and imported annually by each country.

Use oil recovery equipment on the sea surface

This is the next effective solution to recover and collect oil from the water surface after using buoys to control it. Normally, we often use oil suction machines (or oil troughs) to recover the oil that floats and hovers close to the water surface. There are many types of oil extraction machines (troughs) in use today and can be divided into the following types:

• Vacuum cleaner with floating oil suction head;
• The suction machine uses a spray pump to mix water with air;
• Vacuum cleaner with floating head and oil barrier;
• Rotary drum/disc/belt/oil-absorbent vacuum cleaner;
• Fish pen type singing trough;
• Flow-stop type trough;
• Top plate type singing trough;
• Vacuum singing trough;
• Whirling trough.

The above types of suction machines can be divided into 2 types:

• Fixed type: Cannot move on its own;
• Mobile – self-propelled type: Has self-moving propellers.

No matter what type of suction machine or oil trough you use, the basic task of this specialized equipment is to collect (suck, scoop) oil floating on the water surface or suspended close to the water surface. The oil that sinks due to external influences has no effect on this type of equipment. Therefore, one of the things to keep in mind when using this type of equipment is to carry the element of timeliness and mobility (similar to using oil containment buoys). This means that after the oil spills out of the ship, you must promptly use a buoy to surround it and then use this specialized machine (trough) to collect oil from the water surface as soon as possible.
