Description

Branch flare tip apparatus

The present invention relates to a branched flare tip device, and more particularly, to eject the excess gas or waste gas in the device to the outside in order to control the pressure generated in the flare stack device installed in petroleum drilling, refinery or petrochemical plant, etc. And a flared tip device for burning by burning.

Recently, 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 have emerged as a very important problem.

Offshore plants operate from about three to as many as 40 years after they are installed at oil or gas mining sites, so design considerations are also very challenging. There is a need for a variety of high difficulty technologies related to the safety of fires and explosions due to the production of petroleum products as well as the climatic effects of wind and waves and the special environmental conditions at sea.

In addition, due to the recent increase in demand for oil resource development in the deep sea of more than 1,000m, various technologies are being secured and developed.In particular, it is possible to use drilling, production, and storage at the same time for the simple purpose of the existing single function. The trend is to develop offshore plants.

As a result, the demand and price of energy and resources are increasing more and more globally, and the demand and price of offshore plants are rising together, and the trend is expected to continue in the future.

In particular, offshore drilling facilities are expected to continue, ranging from Gravity Based Structures, Fixed Platform Structures, Floating Structures, and Semisubmersible Structures.

Floating Production Storage and Offloading (FPSO), an offshore plant designed to serve floating crude oil production, storage, and transport to onshore refining facilities, is designed to work in the deep sea, rather than offshore structures such as fixed structures. Due to its free movement and utilization, FPSO construction is increasing in line with the development of deep sea resources.

FPSOs are currently used to produce crude oil or natural gas in oil fields. For example, LNG FPSOs are being actively developed due to depletion of oil fields and increasing demand for clean fuel. In deep-sea oilfield development, Oil FPSO or LNG FPSO is a floating offshore refinery that can refine, store and transport crude oil and natural gas while floating at sea.

The FPSO topside is equipped with a flare system that can help prevent FPSO accidents by burning gas from the refinery of refined crude oil and burning gas in an emergency situation.

The flare system also includes a flare tip where the flare gas is burned and where the flame is present, a facility installed on top of the flare stack as shown in FIG. 1.

Flare tip can be divided into HP tip (low pressure tip) and LP tip (low pressure tip) according to the injection pressure of the gas, subsonic tip according to the injection speed of the gas at the nozzle outlet ) And a sonic tip.

The sonic speed tip can inject excess gas at a higher speed than the sonic speed (more than Mach 1 supersonic speed), which has the advantage of increasing combustion efficiency.

However, since the injection speed of surplus gas exceeds the speed of sound, there is a sudden difference in speed between the gas injection airflow beyond the speed of sound and the atmosphere near the flare tip (lower speed of sound), which causes the gas to stagnate. There is a problem that incomplete combustion occurs.

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