New products of oil spill adsorption series make new contributions to environmental protection

Zhejiang Yongkang Zhongyi Industry and Trade Leading Technology Continuously Innovates

People's Daily Market News Online Edition "People's China Weekly" Zhejiang News (Kong Gengsheng Correspondent Shi Jinjun) China is the world's largest importer of crude oil. However, the recent collision of the Iranian oil tanker "Sangi" with 110000 tons of condensate and nearly 1000 tons of marine fuel in the East China Sea resulted in a fire and leakage. Although relevant departments actively used carbon dioxide to extinguish the fire, they were unable to effectively extinguish it in the high wind and waves of the sea conditions. Eventually, the ship exploded and sank, causing a major environmental pollution accident in the East China Sea. The environmental disaster sounded the alarm for the construction of China's emergency response capacity for oil spills on water surfaces and the reserve of emergency technical materials. Experts believe that China urgently needs to develop an oil absorbing material and technology that can extinguish fires and prevent explosions in order to avoid and reduce the harm caused by such accidents to the environment.

The reporter learned that Zhejiang Yongkang Zhongyi Industry and Trade Co., Ltd. has developed a new type of polymer composite adsorption material and technology for fire and explosion prevention against marine pollution caused by ship oil spills. The chairman of the company, Huang Jianshe, proudly summarized the five major characteristics of this adsorption new material specifically for marine pollution prevention and control,

One is that the new material has successfully developed nearly a hundred specifications and models of emergency products, including adsorption particles, adsorption pads, adsorption drag rails, and other types. All emergency products have good water surface buoyancy, can treat various complex water pollution situations, and have complete functions, completely solving the environmental problem of oil spill pollution on the water surface; Specially suitable for emergency response and rescue activities in case of ship oil spills and fires, it can quickly absorb the spilled oil while also providing excellent functions of suffocating air and extinguishing fires and explosions; Mature and reliable technology is used to reduce material costs by 50% and labor costs by 80%.

The second is that the new material has excellent adsorption properties for oils and chemicals floating on the water surface. Can target more than 50 types of heavy oil, light oil, and crude oil liquids that can adsorb floating water surfaces; It can thoroughly adsorb more than 100 aromatic chemical liquids such as toluene, ethyl acetate, n-hexane, etc. in leaked water or on the ground, and the product will not overflow when encountering rainwater after adsorption, effectively avoiding secondary disasters.

Thirdly, the adsorption product has an oil holding capacity of over 99%, which can be used for emergency response to water surface oil spills and chemical leaks, and can solve problems in one go without the need for repeated use; And the usage method is fast, simple and easy to implement, the emergency waste recycling is convenient, and it is easy to dispose of harmlessly; After being treated with this product, the oil spill accident on the water surface showed no colored oil stains observed under sunlight. After testing, the residual oil residue on the water surface was found to be less than 0.5 milligrams per square meter

Fourthly, this new material series of adsorption products has excellent characteristics such as chemical stability, hydrophobicity, high temperature resistance, fire and explosion prevention, non toxicity and no side effects, no oxidation reactivity, non corrosiveness, acid and alkali resistance, long storage period, safe storage and transportation, harmless to emergency personnel and human, animal and aquatic organisms, and environmentally friendly.

The fifth is that the adsorption product of this new material is extremely important and extensive in the field of environmental control and emergency response for oil spill hazardous chemical pollution. First of all, it is a necessary material for emergency response and emergency plan storage in the event of oil and hazardous chemical spills caused by civil commercial ships, warships, ports, coastal and inland waterway transportation operations. Secondly, essential materials for emergency or pollution prevention, fire and explosion prevention, and leak prevention related to chemical production or various industries. The removal, improvement, and restoration of ecological functions caused by the leakage of chemical toxic substances have excellent and unexpected effects on soil pollution. In terms of military purposes, briefly describe one or two aspects, such as preventing military facilities from being contaminated by nuclear radiation and controlling it; Prevention of nuclear cooling water leakage and pollution of environmental facilities during earthquakes in nuclear power plants and facilities; In terms of essential materials for firefighting and rescue of hazardous materials in ground and underground military equipment. The detailed application technology is limited to trade secrets and military secrets, and will not be disclosed in detail here.

The reporter learned that Yongkang Zhongyi Industry and Trade Co., Ltd. is a professional manufacturer of oil spill adsorption new materials listed in the National Ministry of Industry and Information Technology's list of oil spill emergency material production enterprises. The excellent performance of the new material they developed has been tested in practice. On July 15, 2016, while the people of the whole province were preparing for the world-renowned G20 Hangzhou Summit, an 18 ton waste engine oil leakage accident occurred on the G25 Changshen Expressway (Yongkang section) in Zhejiang, China. At that time, a 16 ton waste oil tanker truck from Ningbo Petrochemical Company had an accident on its way from Wenzhou to Ningbo in the Yongkang section, and all the waste oil leaked into the Yongkang River. If the oil pollution is not intercepted in a timely manner and allowed to drift along, it will inevitably pass through the Wuyi River, Wujiang River, Lanjiang River, and eventually reach the Fuchun River and Qiantang River systems, which may cause significant adverse social impacts on the Hangzhou Summit. At this critical moment, the Environmental Pollution Emergency Team of Yongkang Zhongyi Industry and Trade Co., Ltd. took on the task and decisively selected new materials and technologies such as polymer composite FG oil absorbing drag rails, adsorption pads, and adsorption granules to successfully contain and eliminate the pollution source, ensuring that the Hangzhou Summit was not affected in any way. From 8:00 am on July 15th to the end of September, the project has cleared over 1000 meters of oil contaminated river sections, approximately 20000 square meters of polluted water areas, and approximately 300 square meters of highway slopes; Clean up and improve approximately 13000 square meters of contaminated forest and farmland. The use of this new material and technology has resolved the hazards and risks of repeated oil spills, ensuring the safety of downstream water environments, aquatic fish, and plants. This move breaks a new record in the domestic environmental protection model for oil spills. On December 8, 2016, Yongkang Zhongyi Industry and Trade Co., Ltd. was invited to participate in the 5th International Oil Spill Technology Exchange Conference held in Beijing, China. Experts from various countries in attendance highly praised the modern environmental protection advanced technology mode adopted for the disposal of the "7.15" accident.
