DIN EN 13109:2011-04 EN 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
21、 and/or the environment 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 elsew
22、here. Protection 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
23、the drafting of this European Standard that execution of its provisions is entrusted to appropriately qualified and experienced people. DIN EN 13109:2011-04 EN 13109:2010 (E) 5 1 Scope This European Standard specifies methods for the safe gas freeing and disposal of LPG tanks and drums above 150-lit
24、re 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 with any other pressure vessel code. 2 Normative references Not applicable. 3 T
25、erms 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 in accordance with UN number 1965, hydrocarbon gases mixture, liquefied, NOS
26、 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 disposal gas freeing and discarding LPG tanks and drums either in the form of scra
27、p 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 3.5 hydrate hydrocarbon and water compound which forms under reduced tempera
28、ture 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. DIN EN 13109:2011-04 EN 13109:2010 (E) 6 4.2 LPG shall be either: returned to an
29、 in-service LPG tank, or flared through a purpose designed flare stack fitted with a flame arrestor, or vented through a purpose 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
30、 or any potential source of ignition (see Annex B), or a combination of any of these options. For safety and environmental protection 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 examp
31、les of gas freeing methods. NOTE 2 The method of gas freeing should be selected so that it is technically effective and the environmental 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 emis
32、sions to air, raw material consumption and waste (e.g. inert gas, water, steam). NOTE 3 Noise levels from additional equipment (e.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 t
33、he tank or drum (e.g. oily residues) shall be removed and disposed of in a suitable manner before the tank or drum can be considered 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 certif
34、icate shall be required. 4.6 Pressure relief valve assemblies, LPG fill couplings and all other fittings shall be removed. These 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 eq
35、uipment where there is a concern that tanks and drums may be illegally reused for LPG. 5 Scrapping of tanks and drums 5.1 Tanks and 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 per
36、manently defaced. 5.3 Tanks and drums shall be scrapped by either: mechanical shredding, crushing by mechanical means, or cutting 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 i
37、mpact upon the external environment. 5.4 After the above procedures as described in 5.3, tanks and drums shall be considered as scrap material. Scrap material shall be passed only to an authorised scrapping agent who is liable for the effective disposal of DIN EN 13109:2011-04 EN 13109:2010 (E) 7 th
38、e material and the minimising of waste. 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 b
39、e filled with water or inert materials. 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
40、 storage 6.1 The use of tanks and drums 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
41、tanks and drums shall be appropriately 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. DIN EN 13109:2011-04 EN 13109
42、:2010 (E) 8 Annex A (informative) Methods of gas freeing A.1 Preparation for gas freeing In each of the methods described below, tanks and drums should be nominally free of liquid LPG before gas freeing. Once liquid free, tanks and drums should be depressurised e.g. piping LPG vapour from a suitable
43、 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 drum. A.2 Methods of gas freeing A.2.1 By water Care should
44、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 vapour space is left in the tank or drum when the procedure is
45、 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 gas is diluted to less than 20 % of the lower explosive limi
46、t 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 formed in the tank. Hydrates will release LPG vapour when t
47、hey 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. oily residues) shall be removed and disposed of in a suitab
48、le 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; DIN EN 13109:2011-04 EN 13109:2010 (E) 9 electrostatic hazards, and low temperatures e.g. if the inert gas is generated from a liquid phase.
