Device and method for recycling flare heat energy of jacket platform to remove crushed ice in wellhead area

Abstract

The invention provides a device and method for recycling flare heat energy of a jacket platform to remove crushed ice in a wellhead area. The device comprises a heat energy recycling system, a circulating pipeline system, a water supply and storage system and a crushed ice removing system, wherein the heat energy recycling system is installed above a flare and fixed to a flare platform, and can achieve recycle of the flare heat energy; the circulating pipeline system is fixed to a flare boom, the top of a pipeline is connected to the heat energy recycling system, the bottom of the pipeline is connected to the water supply and storage system, and the pipeline is used for conveying cold and hot seawater; the water supply and storage system is arranged on a lower deck of the jacket platform and used for storing the seawater; and the working position of the crushed ice removing system can be adjusted according to needs, and achieves crushing and removing operation of crushed ice piles in the wellhead area of the jacket platform. The device can safely and effectively recycle the flare combustion energy of the jacket platform, uses the recycled heat energy to remove the crushed ice piles in the wellhead area of the jacket platform, and has the advantages of being economical, capable of saving energy, environmentally friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of offshore torch heat energy recovery and marine engineering structure deicing, and specifically designs a device and method for recovering the torch heat energy of a jacket platform and clearing crushed ice in a wellhead area. Background technique [0002] In the process of offshore oil exploitation, the associated gas extracted along with the oil is often flammable and toxic, which will pose a greater safety threat to the structure of the offshore oil platform and the staff. When the offshore oil platform does not have the ability to collect, store and transport such associated gases, or the amount of associated gases is small and lacks collection value, these associated gases need to be discharged, but if they are allowed to escape into the air, it may cause personnel Poisoning and fire, explosion and other accidents. In order to ensure the safety of offshore oil exploitation, these associated gases are...
