Abstract (en)
[origin: EP3135391A1] The subject matter of the invention relates to a method of cleaning the bottom interstitial space (110) and/or wall interstitial space (120) of a storage tank (100; 200), in the event of a sealing failure in those spaces and penetration of a product (150) thereinto. The method of cleaning consists in that a fluid is sucked in, in the case of low-pressure function of bottom interstitial space (110) and/or wall interstitial space (120), or forced in, in the case of high-pressure function of bottom interstitial space (110) and/or wall interstitial space (120), into those spaces. After filling those spaces with the fluid, the sucked-in or forced-in fluid, which has been mixed with a product (150) remaining in the bottom interstitial space (110) and/or wall interstitial space (120), is respectively sucked off or drained from those spaces. In the course of, respectively, sucking off or draining the fluid that was mixed with the product (150) a neutral gas is forced into the bottom interstitial space (110) and/or wall interstitial space (120) of the storage tank (100; 200), and the concentration of explosive gases in the bottom interstitial space (110) and/or wall interstitial space (120) of the storage tank (110; 200) is measured in a continuous manner.
