20、, 20/04/2011 04:17, Uncontrolled Copy, (c) BSIBS EN 13109:2010EN 13109:2010 (E) 4 Introduction This European Standard specifies methods for the safe disposal of LPG tanks and drums. This European Standard calls for the use of substances and procedures that may be injurious to health and/or the envir

21、onment if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health, safety and environmental protection at any stage. Protection of the environment is a key political issue in Europe and elsewhere. Protection

22、of the environment is taken in a very broad sense. The standard takes into consideration the total lifecycle aspects of the activities involved in complying with the standard. These activities include all phases such as scrapping, recycling of materials, etc. It has been assumed in the drafting of t

23、his European Standard that execution of its provisions is entrusted to appropriately qualified and experienced people. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 20/04/2011 04:17, Uncontrolled Copy, (c) BSIBS EN 13109:2010EN 13109:2010 (E) 5 1 Scope This European Standard specifies metho

24、ds for the safe gas freeing and disposal of LPG tanks and drums above 150-litre water capacity. This European Standard is applicable to the following: tanks manufactured in accordance with EN 12542; drums manufactured in accordance with EN 14893, and LPG tanks and drums manufactured in accordance wi

25、th any other pressure vessel code. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 liquefied petroleum gas LPG mixture of predominantly butane or propane with traces of other hydrocarbon gases classified

26、 in accordance with UN number 1965, hydrocarbon gases mixture, liquefied, NOS or UN number 1075, petroleum gases, liquefied NOTE In some countries, UN numbers 1011 and 1978 may also be designated LPG. 3.2 gas free with an LPG concentration in air less than 20 % of the lower explosive limit 3.3 dispo

27、sal gas freeing and discarding LPG tanks and drums either in the form of scrap metal or for use in non-pressure applications 3.4 competent person person who, by qualification, training, experience and resources, is able to make objective judgements related to the safe disposal of LPG tanks and drums

28、 3.5 hydrate hydrocarbon and water compound which forms under reduced temperature and pressure, e.g. venting, and in appearance resemble snow or ice, and can plug equipment 4 Gas freeing of tanks and drums 4.1 Residual liquid LPG shall be safely removed from a tank or drum by a competent person. Lic

30、designed high level vent, in a controlled manner, that ensures that the vented gas is diluted to less than 20 % of the lower explosive limit before it reaches ground level or any potential source of ignition (see Annex B), or a combination of any of these options. For safety and environmental protec

31、tion reasons the first option is preferable. 4.3 Tanks and drums shall be made gas free by a method chosen and controlled by a competent person. NOTE 1 Annex A gives examples of gas freeing methods. NOTE 2 The method of gas freeing should be selected so that it is technically effective and the envir

32、onmental impact reduced to a minimum. After selecting the appropriate method, all suitable measures should be implemented in order to minimise the loss of energy, the emissions to air, raw material consumption and waste (e.g. inert gas, water, steam). NOTE 3 Noise levels from additional equipment (e

33、.g. compressor or vacuum pump) should be evaluated and measures put in place to minimise the impact upon the external environment. 4.4 Any flammable liquids remaining in the tank or drum (e.g. oily residues) shall be removed and disposed of in a suitable manner before the tank or drum can be conside

34、red gas free. 4.5 LPG tanks and drums shall be appropriately labelled e.g. “gas free“ or “N2purged“. WARNING If entry into the tank is necessary, a valid safe entry certificate shall be required. 4.6 Pressure relief valve assemblies, LPG fill couplings and all other fittings shall be removed. These

35、fittings shall be scrapped and recycled or reconditioned where possible. NOTE It may be necessary to render valve outlets beyond repair to prevent reinstallation of LPG equipment where there is a concern that tanks and drums may be illegally reused for LPG. 5 Scrapping of tanks and drums 5.1 Tanks a

36、nd drums shall be certified gas free and a hot work certificate issued prior to hot-work or cutting operations being undertaken. 5.2 All nameplates shall be removed or permanently defaced. 5.3 Tanks and drums shall be scrapped by either: mechanical shredding, crushing by mechanical means, or cutting

37、 each tank or drum into two or more irregularly shaped pieces. NOTE Noise levels from crushing or cutting should be evaluated and measures put into place to minimise the impact upon the external environment. 5.4 After the above procedures as described in 5.3, tanks and drums shall be considered as s

38、crap material. Scrap material shall be passed only to an authorised scrapping agent who is liable for the effective disposal of Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 20/04/2011 04:17, Uncontrolled Copy, (c) BSIBS EN 13109:2010EN 13109:2010 (E) 7 the material and the minimising of wa

39、ste. The selection of the scrapping agent shall consider the total scrapping cycle of the tanks and drums (e.g. energy, transportation, waste). The scrapping agent shall be given details of any tank or drum coatings. 5.5 Underground tanks, if left in place, shall be filled with water or inert materi

40、als. All relevant measures shall be taken to ensure that the underground tank will not leak and contaminate the soil. NOTE National Building Codes or other relevant National Regulations should be considered. 6 Disposal of tanks and drums for uses other than for LPG storage 6.1 The use of tanks and d

41、rums for non-pressure applications is not excluded and can be considered as a good way of recycling tanks and drums which are unfit for service as pressure equipment. Adequate precautions shall be taken with respect to the nature and use of the product stored. The tanks and drums shall be appropriat

42、ely labelled, e.g. “Do not pressurise“. 6.2 Tanks and drums shall be checked to ensure that they are depressurised and gas free. 6.3 All nameplates, any direct stamp markings and other labelling shall be removed or permanently defaced.

Once liquid free, tanks and drums sho

44、uld be depressurised e.g. piping LPG vapour from a suitable tank connection to a safely located flare burner, which should be fitted with a permanent pilot flame. The internal tank pressure should be reduced to a suitable level to enable one of the methods in A.2 to be used to gas free the tank or d

45、rum. A.2 Methods of gas freeing A.2.1 By water Care should be taken to ensure that the tank and its supports are capable of safely supporting the extra weight of water. Water is progressively introduced and LPG vapour expelled via suitable tank connections, selected so that as far as possible no vap

46、our space is left in the tank or drum when the procedure is completed, i.e. when the tank or drum is full of water. The vapour shall be piped, in a controlled manner, to: a purpose designed flare stack fitted with a flame arrestor, or a purpose designed high level vent that ensures that the vented g

47、as is diluted to less than 20 % of the lower explosive limit before it reaches ground level or any potential source of ignition. Once the water has been drained, the tank or drum should be checked by a competent person and certified gas free and suitably labelled “gas free“. WARNING Hydrates may be

48、formed in the tank. Hydrates will release LPG vapour when they melt. Water should be recycled ready for further purging applications or disposed of by appropriate means and should not be allowed to contaminate the ground or drainage systems. Any flammable liquids remaining in the tank or drum (e.g.

49、oily residues) shall be removed and disposed of in a suitable manner before the tank or drum can be considered gas free. A.2.2 By inert gas A suitable inert gas, e.g. nitrogen or carbon dioxide, is used to displace and dilute the LPG vapour to a gas free level. Care should be taken to avoid hazards associated with inert gases such as: over pressurisation of the tank or drum; Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 20/04/2011 04:17, Uncontrolled Copy, (c) BSIBS EN 13109:2010EN 13109:2010 (E)
