Description

Production gas processing module and ship for production gas processing having the same}

The present invention relates to a production gas processing module and a production gas processing vessel having the same, and more particularly, a refrigeration for lowering the compression performance and efficiency of a gas compressor to an optimum temperature that can further increase the compression performance and efficiency according to the temperature and composition of the raw material gas. In addition, a ship equipped with such a production gas treatment module enables compact design, versatility, and economical treatment. Furthermore, it is easy to move, thereby improving operational efficiency for repair and development of a number of oil wells. I did it.

In general, FPSO (Floating Production Storage and Offloading) is referred to as a floating production storage and unloading facility structure. In general, a facility that extracts oil or gas from an oil well or a natural gas well found by a drill ship, purifies and stores it. Equipped. In addition, the oil or gas stored in the FPSO is transported on land through a shuttle tanker.

The FPSO is fixed at a point on the sea and is mined for nearly 20 years, so it is produced at the maximum capacity for oil and gas production with a service life of approximately 20 to 25 years. Processing modules are manufactured and mounted, and various equipment and facilities connected thereto are also designed to suit the maximum capacity.

However, as described above, the FPSO has to be designed with the maximum capacity in consideration of the maximum operating scenario with a 20 to 25 year service life, so that the design scale becomes excessively large, and the production gas treatment module and the production oil treatment module Of course, there was a difficulty in reducing the drying cost and drying period due to the high specifications applied to various equipment and facilities linked to this.

In particular, the maximum production of oil or gas to be mined decreases, and during partial load operation, idle production gas and oil processing modules are generated, which prevents economical production and processing, as well as compactness for FPSO in consideration of such partial load operation. One design is also difficult. In particular, since FPSO is not easy to move, it is not easy to repair using a dock, and immediate input is not possible, so there is a problem that it is not possible to increase the operational efficiency for the development of a number of oil wells.

On the other hand, the production gas processing module in FPSO provides a function of purifying the gas by compressing the mined production gas at high pressure, and is designed to achieve optimum performance in consideration of the temperature and composition of the production gas of each oil well. If FPSO with the same compressor has to be installed in different oil wells, there is a problem in that the compression performance and operation efficiency cannot be improved due to collective compression using a gas compressor because the temperature and composition are changed.

As an example, (a) the production gas of an oil well has 80% methane content and a temperature of 40 degrees Celsius, (b) an oil well has 90% methane content and a temperature of 60 degrees Celsius. If the same compressor is applied Driving performance is bound to change.

In addition, in the present invention, the control unit converts the input temperature measurement signal and component detection signal into a measurement temperature value and a component detection value, respectively, and converts the measured temperature value and component detection value into a preset temperature value and component detection previously input to the control unit. The purpose can be achieved through a production gas processing module that applies an electrical control signal corresponding to the set temperature value and the component detection value corresponding to the value to the refrigerator.

In addition, in the present invention, the object can be achieved through a production gas processing module that is connected to a fuel supply branch line between the source gas supply line and the driving source so that the source gas transferred along the source gas supply line can be supplied to the driving source.

On the other hand, in the present invention, it is possible to achieve the object through a production gas treatment vessel that installs the production gas treatment module on the deck of the hull.

When a production gas processing module according to the present invention and a production gas processing vessel equipped with the same are used, the gas compressor is reduced to an optimum temperature that can increase the compression performance and efficiency of the gas compressor according to the temperature and composition of the raw material gas. It can be expected to increase the compression performance and driving efficiency.

In addition, when a production gas treatment module and a production gas treatment vessel having the same are used, a compact design and economical treatment can be expected through a ship equipped with only the production gas treatment module.

2 is a view showing a production gas processing vessel equipped with a production gas processing module according to the present invention.

Hereinafter, a production gas treatment module according to the present invention and a production gas treatment vessel having the same will be described through a preferred embodiment.

First, the production gas processing module 10 according to the present invention includes a driving source 14 composed of either a gas engine or a gas turbine and the driving source 14 so as to provide a driving force in a state provided in the module body 12. A gas that is connected to the drive shaft 16 in an interlocking state and operates with a driving force transmitted from the drive shaft 16, and a gas connected through an output line 20 connected to the output port of the gas compressor 18. Purifier 22, a refrigerator 26 connected through an input line 24 connected to an input port of the gas compressor 18, a raw material gas supply line 28 connected to the refrigerator 26, and the raw material gas supply A temperature sensor 30 and a component detector 32 installed on the line 28 to detect the temperature and component of the raw material gas, the temperature sensor 30 and component detector 32, and electrical signal lines 34 and 36, respectively. It is configured to include a control unit 40 connected to the refrigerator 26 and also connected to the electric signal line 38, respectively.

Further, the fuel supply branch line 42 is branch-connected from the source gas supply line 28, and the fuel supply branch line 42 connected in this way is connected to the driving source 14, and from the source gas supply line 42 A configuration in which a part of the supplied raw material gas is sent to the driving source 14 and used as driving fuel is also included.

A production gas treatment module according to the present invention and a production gas treatment ship having the same will be described in detail.

For example, the raw material gas G mined through FPSO is transferred to the raw material gas supply line 28 as it is. At this time, a temperature sensor 30 and a component detector 32 are respectively installed on the source gas supply line 28, so that the temperature and components of the source gas G transferred along the source gas supply line 28 are respectively It is detected and inputs the temperature measurement signal and the component detection signal accordingly to the control unit 40.

The control unit 40 converts the input temperature measurement signal into a measured temperature value, and also converts the input component detection signal into a component detection value.

In addition, the control unit 40 compares the converted measured temperature value and component detection value to the preset temperature value and component detection value previously input to the control unit, and creates a program corresponding to the set temperature value and component detection value corresponding thereto. After execution, an electrical control signal accordingly is applied to the refrigerator 26.

In the refrigerator 26, the refrigeration operation intensity of the refrigerator 26 is variably adjusted according to the electrical control signal input from the control unit 40 to increase the compression performance of the crude gas G and the operation efficiency of the gas compressor. It is transferred to the gas compressor when it is lowered to the temperature of.

In other words, in the background art, the gas compressor 18 provided in the production gas processing module 10 does not increase the compression performance and operation efficiency by collectively compressing the raw material gas G regardless of the temperature or component. Although there was a problem, in the present invention, it is possible to increase compression performance and operation efficiency by lowering the temperature to a temperature at which the compression performance and the efficiency of the gas compressor 18 can be increased according to the temperature or component of the source gas G.

On the other hand, as explained in the background art, since the FPSO is designed with the maximum capacity in consideration of the long-term life and maximum operating scenarios, the design scale is excessively large and high specifications are applied, and the drying cost and drying period cannot be reduced. There was a problem that economic production and treatment could not be achieved due to the generation of idle production gas and oil treatment modules due to reduction of the maximum production of oil or gas. In the present invention, the production gas treatment vessel 50 equipped with the production gas treatment module is equipped with only the production gas treatment module 10 described above on the upper surface of the deck 54 of the hull 52, so that the design scale is excessive. Compared to the growing FPSO, drying cost and drying period can be reduced, and compact design is possible.

In particular, the FPSO was not easy to move, so it was not easy to repair and repair through the dock. However, the production gas treatment vessel 50 according to the present invention is repaired and repaired through the dock when the production gas treatment module 10 fails. Repair is easy, and immediate transfer input is possible, so that versatility and economical production processing can be achieved, and further, operational efficiency for the development of a number of oil wells can be improved.
