The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. The versions shown are valid when this standard is published. All standards are subject to revision. Parties using this standard should explore the possibility of using the latest version of the following standards. GB18188.1—2000 Technical conditions for oil spill dispersants 3 Definitions
This standard adopts the following definitions.
3.1 Oil spill dispersant [GB 18188.1--2000] Chemical preparations that can emulsify, disperse or dissolve floating oil on the water surface in water. Oil spill dispersants are composed of a mixture of surfactants and solvents.
3.2 The water areas under jurisdiction of the People's Republic of China FGB 18188. 1- 2000]
This standard refers to the water areas where the "Marine Environment Protection Law" and the "Water Pollution Prevention and Control Law" are applicable. 3.3 Precipitating agent Chemical preparations that increase the specific gravity of oil through adsorption, adhesion, etc., and promote its sinking from the surface of the water to the bottom of the water. 3.4 Coagulating agent
Chemical agent that can gather floating oil on the water surface into flakes, blocks or spheres. 3.5 Light oil
This standard refers to petroleum fractions with a 90% distillation temperature not higher than 230℃. Technical requirements for oil spill dispersants
The performance indicators of oil spill dispersants shall comply with Chapter 5 of GB18188.1-2000. 5 Principles for the use of oil spill dispersants
Oil spill dispersants can be considered for treating floating oil or accidental oil spills on the water surface in the following cases: a) Floating oil or accidental oil spills on the water surface may move to the coast, aquaculture sites and other waters sensitive to oil spills, threatening the interests of commerce, environment or comfort, and before reaching the above-mentioned sensitive areas, it cannot be dispersed by itself through natural evaporation or the action of wind, waves and currents, nor can it be contained or recycled by physical methods; Approved by the State Administration of Quality and Technical Supervision on September 7, 2000 and implemented on October 1, 2001
GB 18188.22000
h) For oil spills that are difficult to handle by physical and mechanical methods, the total damage caused by using oil spill dispersants to promote their dispersion into the water body is less than the damage caused by leaving the oil on the water surface without treatment; c) Oil spills occur in non-port waters with a depth of more than 20m, and can be used first and then reported to the competent authorities; d) The type and water temperature of floating oil or accidental oil spills on the water surface are suitable for chemical dispersion (generally speaking, the water temperature needs to be higher than the pour point of the oil to be treated by more than 5°C), and the weather, sea conditions and other environmental conditions are suitable for dispersing oil; e) In force majeure situations such as oil fires and explosions that have occurred or may occur and endanger human life or facility safety. 6 Principles for limiting the use of oil spill dispersants
The following situations should not use oil spill dispersants. However, force majeure situations that may or may occur and endanger human life or facility safety are excluded. a) The spilled oil is a volatile light oil such as gasoline or kerosene, or a thin oil film with rainbow characteristics; b) The spilled oil is a high wax content, high pour point oil that is difficult to disperse chemically; c) The spilled oil is not fluid at ambient water temperature or forms thick fragments of oil-in-water emulsions with clear edges after a few days of wind erosion; d) The spilled oil occurs in a closed shallow water area or calm waters; e) The spilled oil occurs in a freshwater source or an area that has a significant impact on aquatic resources. 7 Application method Www.bzxZ.net
Use appropriate tools to evenly spray the oil spill dispersant on the oil film on the water surface, and the spray particle size is about 400 to 700μm. 7.1 Application amount
7.1.1 When using oil spill dispersant to treat oil spills, the application amount depends on factors such as the characteristics of the oil spill, the emulsification properties of the oil spill dispersant, and the operating conditions. The dosage of conventional dispersants is generally 30% to 100% of the amount of oil to be treated: the dosage of concentrated dispersants is generally 10% to 20% of the amount of oil to be treated.
7.1.2 When using concentrated dispersants that can be diluted with water, the concentration of oil spill dispersants in the diluent should be above 10%. All types of oil spill dispersants should be used in stock solution.
7.1.3 When dealing with oil fires on water, a fire hose can be used to siphon 3% to 10% of oil spill dispersants to spray on the burning oil. 7.2 Spraying method
7.2.1 According to the estimation of the thickness and area of ​​the oil film, appropriately adjust the operating ship speed and the amount of oil spill dispersant sprayed to ensure the appropriate application ratio of oil spill dispersants to oil.
7.2.2 The speed of the spraying ship is about 2 to 7 nmi/h, and the spraying arm length is generally not more than 15m. Adjust the nozzle height to make it as close to the wave crest as possible.
7.2.3 The alcohol spraying boat should operate against the wind along the wind axis, along the edge of the oil film toward the middle thick oil layer. Single boat continuous operation or multiple boats parallel, staggered operation can be adopted, and the spraying boundaries of each boat intersect but do not overlap. When the oil spill is driven by the wind to form a narrow oil belt, the leeward spray arm can be used to spray along the oil belt.
7.2.4 When operating in relatively calm sea conditions, mechanical stirring must be provided: for example, a crushing plate or plastic chain towed behind the spray arm. The upper limit wind speed suitable for operation is 25-28nmile/h. 7.2.5 For oil stains on rocks or facilities on the shore, alcohol oil dispersant can be sprayed first, and then it can be softened and scrubbed with a hard brush, and the treated waste liquid can be collected and disposed of in accordance with relevant waste disposal regulations. Finally, rinse with a water gun. 7.3 Safety
Operators who spray alcohol oil dispersant should wear personal protective equipment, such as waterproof work clothes, gloves, goggles or masks. 8 Application Management
8.1 The application management of oil spill dispersants shall comply with the provisions of the Marine Environmental Protection Law and the Water Pollution Prevention and Control Law of the People's Republic of China. 8.2 Products approved by the Oil Spill Dispersant Approval Agency of the People's Republic of China shall be used in any case. 8.3 The competent authorities may, based on the investigation and comprehensive evaluation of the opinions of local fishery experts, environmental experts and local governments, allow managers of certain ports, oil transfer stations or near-shore oil and gas operations to use limited amounts of oil spill dispersants (limited to 0.5m\ each time) in limited waters for emergency treatment of oil spill accidents. The application of oil spill dispersants should be included in the grassroots oil spill emergency plan. 8.4 After the application of oil spill dispersants to treat oil spills, a report should be submitted to the competent authorities, the main contents of which should include: a) the name of the organization that applied the oil spill dispersant; b) the time, location, process (including other anti-oil spill measures adopted and their effects), scale and oil spill characteristics of the oil spill accident; c) the weather, sea conditions, water temperature, coastline type and other environmental conditions when the oil spill and the application of oil spill dispersants occurred; d) the method of using the oil spill dispersant, the start and end time of the operation, and the evaluation of the treatment effect; e) the name, dosage, production time and type approval certificate number of the oil spill dispersant; ) Problems and suggestions.
