Solar Reflective Paint Using Nano Materials

Posted on by Haianh

BIGNANOTECH, in collaboration with a team of expert researchers, has successfully developed the S-CORIN heat reflective paint technology using domestically produced nano materials. This solar reflective paint meets stringent international technical standards while being more affordable.

As a tropical country with an average annual radiation of about 120 kcal/cm²/year, Vietnam experiences intense heat during the summer, leading to the urban heat island effect in major cities like Hanoi and Ho Chi Minh City. Recognizing the urgent need for materials that can reduce solar radiation effects on buildings and equipment, scientists focused on developing the S-CORIN solar reflective paint, specifically for fuel and chemical storage tanks.

The solar reflective coating of S-CORIN heat reflective paint operates on the principle of diffuse reflection. With a tightly structured composition that includes highly reflective nano particles interspersed with micro particles, using this nano reflective paint can reduce the surface temperature of steel tanks by 10-19°C and the internal temperature by approximately 8-15°C compared to conventional paint. Additionally, the weather resistance of nano paint exceeds 1,500 hours in accelerated weathering tests.

S-CORIN heat reflective paint is a high-quality product tested and used by many major entities in Vietnam. The paint can reflect up to 80% of heat and UV rays, helping to maintain stable internal temperatures in tanks. According to testing and quality assessments by SUZUKAFINE (one of Japan’s top five paint companies), the paint samples have significantly higher heat reflectivity than existing heat-resistant paints available domestically and internationally.

Furthermore, applying S-CORIN solar reflective heat-resistant paint to the external surfaces of buildings and volatile fuel/chemical storage tanks is an effective and economical solution to combat the urban heat island effect. It can save up to 40% of energy consumption for cooling equipment, prevent the loss of volatile fuels/chemicals, contribute to energy security, and help mitigate climate change.

Harmful Effects of Oil Spills at Thermal Power Plants and Solutions

Posted on by Haianh

A. HARMFUL EFFECTS OF OIL SPILLS

Oil pollution and spills cause numerous direct and indirect impacts on ecosystems and riversides in various aspects. When oil spills reach the shore, they hinder many economic development activities.

1. Environmental Impacts of Oil Spills

  • Water Pollution:

Research by scientists and environmental experts indicates that when the concentration of petroleum and its products in water reaches 0.5mg/l, oil starts to emit an unpleasant odor. The chemical indicators of water change drastically when the concentration of petroleum and its products exceeds 100mg/l.

The presence of oil films on the water surface reduces oxygen exchange between the air and water, decreasing dissolved oxygen levels and increasing CO2 levels, causing a drop in water pH. Since oil films are dark-colored, they have a high solar heat absorption capacity, leading to increased water temperatures. The easily soluble components in oil, mainly petroleum ethers, are highly toxic to aquatic life.

  • Disrupting the life activities of organisms:

Oil covers the cell membranes of lower organisms like plankton and protozoa, disrupting osmotic pressure regulation, causing mass deaths of lower organisms, juveniles, and larvae. Oil adhering to organisms’ bodies hinders respiration, metabolism, and movement.

Oil concentrations in water as low as 0.1mg/l can be lethal to plankton, the first link in the aquatic food chain. For bottom-dwelling organisms, oil pollution significantly affects juveniles and larvae. Oil absorbed by adult organisms reduces their usability due to the oil odor.

Fish are severely impacted by oil spills, with effects depending on the solubility of harmful compounds in oil. Oil sticking to fish reduces their usability due to odor, and fish eggs can be rendered nonviable by oil contamination. Oil pollution can cause mass fish deaths due to decreased dissolved oxygen in the water.

  • Potential toxicities in the ecological environment:

Oil spills indirectly affect organisms by impeding oxygen exchange between water and the atmosphere, promoting the accumulation of toxic gases like H2S and CH4, raising pH levels. Oil sediments accumulate in the sediment, increasing oil content and causing toxicity to bottom-dwelling organisms.

  • Impact on Fisheries:

Decline in fishing and aquaculture productivity due to reduced fishery resources in oil-affected areas. Fish and seafood often acquire an oil odor, making them unsellable.

  • Hindrance to Shoreline Economic Activities:

Oil spills drifting with surface currents, waves, and tides adhere to rocks and coastal areas, causing aesthetic degradation and unpleasant odors for tourists, reducing local tourism revenue.

2. Impact on Economic Activities:

Aquaculture is one of the crucial economic sectors in coastal and riverside communes. These areas use river and sea water directly for aquaculture. Therefore, in the event of an oil spill contaminating the water source, these farming areas will be the first to be affected. Shrimp and clams are highly sensitive to polluted water, so the damage level will be significant.

When oil infiltrates the ponds, it gradually accumulates in the organisms’ bodies until it reaches a certain threshold, leading to death (initially, shrimp show signs of sequential death, and after a few days, they die en masse). Another cause is that the oil spill depletes the water’s oxygen supply for the aquatic life, leading to death.

It should also be noted that since most local residents invest a considerable amount of capital in aquaculture, an incident will severely impact their economic livelihoods if not promptly addressed.

3. Impact on Natural Resources and the Environment:

Oil toxicity varies daily based on pollution concentration. Although the most toxic components of oil can dissolve in water and evaporate quickly, all aquatic organisms can accumulate oil even at very low concentrations. Oil accumulation in sediments and sand in stagnant waters poses long-term ecological risks.

The survival of flora and fauna depends on natural instincts and external factors. During spawning seasons, organisms become more sensitive to oil. Recovery of species depends on the timing of the oil spill, recovery efforts, and the accumulated oil content in each species. Species with rapid growth rates recover quickly, while slow-growing species may take years to fully recover.

B. EFFECTIVE SOLUTIONS FOR HANDLING OIL SPILLS AT THERMAL POWER PLANTS

To mitigate oil spill risks at thermal power plants, strict environmental protection and safety measures must be implemented. Enhanced monitoring and control, adherence to oil use regulations, and treatment of oily wastewater are essential.

Thermal power plants must have comprehensive emergency response plans to handle oil spills promptly. Effective oil spill management technologies are crucial for reducing pollution risks and enhancing industrial hygiene at plants and downstream areas.

Some products suitable for spill handling, industrial cleaning and oil pollution prevention at thermal power plants include:

In conclusion, oil spills and leaks at thermal power plants are significant threats to the environment and human health. Addressing these issues requires proactive management by plant authorities to protect worker health and the environment.
