Method for improving efficiency of processing marine oil spilling by in-situ combustion method

Abstract

The invention discloses a method for improving the efficiency of processing marine oil spilling by an in-situ combustion method. The method comprises the following steps that in a conventional combustion region formed by an oil containment boom, metal heat conducting bars are vertically fixed, wherein a part which is exposed from a liquid surface, of each of the metal heat conducting bars is a heat collection section, and a part which is immersed in an oil spilling layer, of each of the metal heat conducting bars is a heating section; the heat collection sections absorb massive energy transmitted by the heat radiation of frame in the process of combustion, and transmit the absorbed energy downwards through own heat conduction effect, so that the heat quantity absorbed by the oil spilling layer is directly improved; and at the same time, under the effect of high temperature, the heating sections which are immersed in the oil spilling layer, of the metal bars, accelerate heat exchange between the heating sections of the metal bars and the surrounded spilled oil, so that the heat transfer effect in the oil spilling layer is improved, the effect that the oil spilling layer absorbs the heat quantity of the flame is improved, the purposes that emulsified oil is fully ignited and the combustion rate is improved are achieved, and the combustion speed and the combustion efficiency for processing a marine oil spilling accident by the in-situ combustion method are improved.

Description

technical field [0001] The invention relates to the application field of marine oil spill treatment, in particular to a method for improving the efficiency of treating marine oil spill by in-situ combustion. Background technique [0002] In the process of offshore oil and gas production and transportation, oil spill is a common and harmful accident. Oil spills at sea often have disastrous effects on the local marine environment, biodiversity and fisheries. Therefore, it is of great significance to quickly and effectively deal with marine oil spills to reduce water pollution caused by oil spills and protect the ecological environment and biodiversity. At present, the methods commonly used to deal with marine oil spill accidents mainly include physical methods, chemical methods, biological treatment methods and in-situ combustion methods. [0003] The in-situ burning method is to use the oil containment boom to gather the spilled oil, and then use the method of direct burnin...

AI Technical Summary

Problems solved by technology

The high emulsification rate makes it difficult for the spilled oil to be ignited or continue to burn, reducing the efficiency of oil spill handling

[0006] (2) The burning rate is low

A small proportion of heat feedback results in a lower rate of flammable vapors from the spilled oil, that is, a lower burning rate, which reduces the efficiency of oil spill handling
