Description

Flare tip apparatus installation method

The present invention relates to a flare tip device installation method, and more particularly, to control the pressure generated in the flare stack device installed in a petroleum drilling, oil refinery or petrochemical plant, etc. It relates to a method for installing a flare tip device that burns and burns.

In recent years, as industrialization and industrialization accelerate, the use of natural resources (petroleum, natural gas, etc.) is gradually increasing, and stable production and supply of natural resources with limited reserves is emerging as a very important problem.

Since the offshore plant is installed at the oil field or gas mining site, it operates from about 3 to 40 years, so the design considerations are also very demanding. Various and high-difficulty technologies are required related to securing stability against fire and explosion through the production of petroleum products as well as climatic effects such as wind and waves and special environmental conditions at sea.

In addition, due to the recent increase in demand for petroleum resource development in deep seas of 1,000m or more, technologies are being secured and developed in a variety of ways. The trend is to develop offshore plants for use.

As a result, the global demand for energy and resources is increasing and prices are rising more clearly, and the demand and prices of offshore plants are also rising, and the same trend is expected to continue in the future.

In particular, offshore drilling facilities are expected to continue steadily, ranging from gravity based structures, fixed platform structures, floating structures, and semisubmersible structures.

FPSO (Floating Production Storage and Offloading), an offshore plant designed to function as a loading and unloading function for floating crude oil production, storage, and transportation to an onshore refinery, is a facility designed to work even in the deep sea. Due to its freedom of movement and high availability, FPSO construction is increasing in line with the development of deep sea resources.

FPSO is currently used in oil fields to produce crude oil or natural gas. For example, LNG FPSO has been actively developed in recent years due to the depletion of oil fields and increasing demand for clean fuels. In deep-sea oil field development, Oil FPSO or LNG FPSO can be said to be a floating offshore refinery that can purify, store and transport crude oil or natural gas while floating on the sea.

On the top side of FPSO, a flare system is provided to prevent accidents that may occur in FPSO by burning the waste gas generated in the process of refining the drilled crude oil and the gas in an emergency situation.

In addition, the flare system includes a flare tip, which is a facility installed at the top of a flare stack, as shown in FIG. 1, where a flare gas is burned and a flame exists.

The flare tip can be divided into a high pressure tip and a low pressure tip according to the injection pressure of the gas, and a subsonic tip according to the injection speed of the gas at the nozzle outlet. It can be divided into a supersonic tip.

The sonic tip can inject excess gas at a higher speed (supersonic speed of Mach 1 or higher) than the speed of sound, and has the advantage of increasing combustion efficiency through this injection speed.

However, since such a flare tip essentially involves a high-temperature combustion reaction, radiant heat is generated by a flame, and various types of tip nozzles are formed, but there is a problem that it is not standardized in an efficient structure and varies depending on the situation.

In addition, there is an urgent need for a configuration and installation capable of simultaneously burning a large amount of gas while eliminating stagnation of flare gas.
