What is Pressure Reducing Skid

Pressure reducing skid is a pressure reducing equipment commonly used in the industrial field, its main role is to reduce the pressure in the high pressure pipeline to the appropriate pressure range required to ensure the normal operation of the pipeline and equipment. In many industrial fields, pressure reducing skid is an indispensable part, such as petrochemical, gas transportation, machining and so on.

Advantages of Pressure Reducing Skid

Reduce the amount of on-site construction and shorten the construction period. Traditional on-site equipment and fixed equipment required after equipment procurement, on-site equipment and commissioning, construction cycle is long, but also requires planning, construction, suppliers of the contact harmony, high operating capacity, requires the construction party has extensive construction experience, understanding of manufacturers and supporting equipment equipment requirements, the user needs to be equipped with professional and technical personnel to cooperate. Pressure reducing skid with integrated supply, assembly, testing, inspection are completed in the factory, greatly reducing the site construction workload, only need to connect in and out of the pipeline and electrical equipment wiring, equipment debugging is convenient, the construction cycle than the traditional on-site equipment to shorten the time required by half or even more.

Improve the engineering manufacturing efficiency and ensure the quality of engineering manufacturing. On-site equipment and fixed equipment require good professionalism and construction experience of on-site construction personnel. As far as this project is concerned, it is difficult for the local construction team to ensure that the welding of station equipment meets the quality requirements. Skid-mounted equipment is supplied as a whole, the quality is easy to be guaranteed, avoiding the rework caused by unqualified welding on site and improving the construction quality and efficiency.

Saving engineering resources and reducing engineering investment. Skid-mounted equipment can make full use of the three-dimensional space, so that the equipment is compactly placed, saving the amount of information used, and its footprint is only 40% to 60% of the footprint of the fixed equipment on site, which can save land resources. Integrated supply reduces the need for on-site construction technicians, reduces on-site construction costs, saves the operator to the site equipment, equipment for various travel costs, as well as the completion of the operation equipment, the remaining material round-trip transportation costs. At the same time, due to the comprehensive testing before leaving the factory, reducing the workload of on-site commissioning, reducing commissioning costs.

Convenient operation and maintenance, on-site equipment is fixed, due to the suppliers are usually different, equipment problems, spare parts procurement needs to be provided by the supplier to provide adequate technical support, follow-up operation and maintenance costs and management is relatively difficult. Product problems can be resolved by the supplier in a timely manner, improving the stability and reliability of equipment operation, but also facilitates the maintenance and management of equipment.

High reuse value. The pressure reducing skid is highly movable and has a high reuse value. The skid module can be relocated and used many times and in many places as a whole, and the equipment reuse rate is as high as 90%.

Usage of Pressure Reducing Skid

A Pressure Reducing Skid (PRS) is a device used in a variety of industries to reduce the pressure of gases or liquids in a pipeline.The purpose of a PRS is to regulate the flow of fluids and gases at a specific pressure level to ensure that they meet required standards.

In the oil and gas industry, PRS systems are used to reduce the pressure of natural gas or crude oil during transportation. This is important because these fluids are often transported at very high pressures, which can lead to explosions or other dangerous accidents. With PRS systems, the pressure is controlled and reduced to safe transportation levels.

In manufacturing, PRS systems are used to regulate the pressure of steam or other fluids used in various processes, such as heating or cooling. By controlling pressure, these systems ensure that manufacturing processes run smoothly and efficiently.The purpose of PRS is to improve the safety, efficiency, and reliability of a variety of industries that rely on the transportation and regulation of fluids and gases.PRS systems play an important role in ensuring the smooth operation of pipelines, manufacturing processes, and other industrial applications.

Problems Encountered in Pressure Reducing Skid Pressure Reduction

The pressure reduction system is separate from the temperature reduction system. The temperature reduction skid is mainly used in poor working conditions such as low steam flow and is not suitable for temperature reduction valves. In saturated steam conditions (low pressure is mainly considered low steam flow), the use of venturi cooling method, cooling water fully atomized, cooling effect is better.

Nowadays, the vacuum device industry wants to continue to develop, fundamentally adjust the industrial structure, after all, the life cycle of the vacuum device is not as long as the life of the device, so many manufacturers have carried out a proper update of their devices, with the promotion of science and technology, the vacuum device has now been presented with the momentum of the integration of machine, electricity, gas, life, to be able to work efficiently and save energy.

In the pressure pipeline, usually high-pressure gas enters the pipeline through the shut-off valve, and is depressurized through the regulating valve of the pressure reducing skid, so that it reaches the required pressure, and then transported to various places.

In general pressure regulator, after the high pressure gas is depressurized through the pipeline, the gas is directly output through the pipeline without buffer because the diameter of the inlet pipe and the delivery pipe at both ends of the regulator are the same, which will cause the gas pressure to be unstable.

Usually, some manufacturing companies will set up a spherical buffer space in the gas pipeline, so that the decompressed gas along the pipeline into the spherical buffer space for buffering, so that the output gas pressure tends to stabilize.

The spherical buffer space is difficult to process and needs to be welded on the gas pipeline, which increases the workload, and when the welding quality is not good, it is easy to have gas leakage.

Precautions for Selecting Pressure Reducing Skid

According to different working conditions and use conditions, it is very important to choose the right pressure reducing skid. When choosing a pressure reducing skid, you need to consider the material of the pipeline, pressure, flow rate, medium and other factors. The following points should also be noted:
Select the appropriate pressure reducing skid, the pressure should not exceed its rated pressure range;
Consider the nature of the fluid, such as whether it is corrosive, hazardous substances, the impact of the valve material;
To consider the medium temperature, temperature fluctuation range and other factors;
To be considered according to the pipeline structure, installation methods, space environment and other factors.

Working Principle and Classification of Pressure Reducing Skid

Pressure reducing skid, also called pressure reducing valve or pressure reducer, is a device that controls fluid pressure by adjusting the valve aperture or changing the inner diameter of the pipeline. When the pressure in the pipeline exceeds the set value, the pressure reducing skid will be automatically activated to automatically release the excessive pressure, so as to protect the system equipment from damage due to overpressure. Pressure reducing skid usually consists of piston, seat, valve, adjusting spring, adjusting screw, etc., according to its structure and working principle can be divided into many kinds:

Direct-acting pressure reducing skid
Direct-acting pressure-reducing skid is a relatively simple pressure-reducing valve, composed of valve body, valve seat and spring. When the pressure of the liquid or gas in the pipeline exceeds the set value, the spring will be compressed, the valve opens, and the overpressurized liquid or gas is discharged from the valve, thus protecting the normal operation of the system.

Indirect acting pressure reducing skid
Indirect-acting pressure reducing skid is mainly composed of main valve, control valve and actuator. It is characterized by dynamic adjustment of pressure fluctuation before and after the main valve through the control valve and actuator, so as to achieve the effect of pressure reduction. Indirect acting pressure reducing skid is widely used in petroleum, chemical, metallurgy, electric power, light industry and other fields.

Pressure Reducing Skid Precautions

When using the pressure reducing skid, there are several important precautions to be observed to ensure the safe and effective operation of the pressure reducing skid:

1. Pre-operation checks
• Ensure that the regulator, shut-off valve, overpressure relief valve, pneumatic valve, instrument air and other equipment is normal.
• Check that the heating system is normal.
• Connect the high-pressure hose of the unloading pipe with the quick-fitting connector on the CNG tanker.
• Close the pressure reducing skid pressure gauge, open the pressure reducing skid temperature transmitter, pressure transmitter control valve.
• Open the control cabinet of the pressure reducing skid, and the button of the emergency shut-off valve is in the automatic state. Calibrate the display parameters with the on-site display parameters of the pressure regulator.
• Turn on the electric heating, adjust the water temperature to the rated temperature.
• Turn on the air compressor, open the third-party gas supply valve, pneumatic emergency shut-off valve should be in the open state.

2. Operation precautions
• In normal gas supply, the valve should be opened and closed slowly, and fast opening and closing is strictly prohibited.
• When stopping the gas supply and closing the pressure reducing skid, the valve of the unloading port of the tanker should be closed first, and then close the valve of the inlet pipeline of the unloading pipe, and then close the valve of the pressure reducing skid in turn, and finally close the heat exchanger. In all operations, the opening and closing of the valve needs to be carried out slowly, it is strictly prohibited to open and close the operation quickly.

3. Equipment selection and maintenance
• Before purchasing natural gas pressure reducing skid, you need to understand the actual peak natural gas consumption and gas pressure. According to the actual demand to choose the appropriate pressure reducing skid models and specifications, to avoid the selection of too large or too small to cause problems.
• The pressure reducing skid must be regularly calibrated and the pressure gauge must be regularly inspected to ensure the reliability of pressure regulation and the accuracy of the pressure gauge reading.
• If the pressure reducing crowbar is found to be frozen during use, it should be thawed with hot water or steam, and should never be baked with flame or red iron.
• The pressure reducing crowbar must be kept clean and must not be contaminated with grease or dirt.

How to Operate the Decompression Sled

Every time before use, should check the central console of the instrument and indicator status, hot water and compressed air parameters and equipment operating conditions, the site process and valve position. After the above checks are normal, open the unloading valve, the total inlet valve, press the field start button, the pressure regulator into normal use.

When normal shutdown, close the unloading valve, the total inlet valve, press the shutdown button. According to the process requirements to close the relevant valves, auxiliary equipment, if necessary, should consider the hot water system emptying and electrical system power failure. The regulator is in shutdown standby mode.

When the CNG unit is in an abnormal situation, the self-protection system will automatically close the emergency shut-off valve and alarm in the central control room with sound and light signals. After human intervention or automatic elimination of the abnormal condition, it can be restarted according to the normal startup procedure. At any time, as long as the pressure at all levels of ultra-high, heat transfer return water temperature is too low and any other abnormal conditions exist, the regulator is forced to shut down until the cause of the abnormality is found and eliminated, then it may be reused.

Emergency stop buttons are provided in the central control room and on site in case of any perceived emergency stop.

Although the CNG unit is equipped with a function to prevent the impact of medium gas flow, care should be taken not to open and close the manual valves too quickly during use.

Periodic inspections should be made and recorded to ensure stable operation. Inspection should observe the indoor instrumentation, indicators, outdoor instrumentation, indicators, operating noise, dynamic and static sealing points.

Open and close the valves regularly, check the opening and closing flexibility, and add lubricating grease.

Regularly check and test the instrument control system and self-protection interlocking system. And should be measured in accordance with the relevant provisions of the measurement, display instrumentation for regular calibration.

Regular sub-channel overhaul. After overhaul should be in accordance with the requirements of the relevant norms for construction and acceptance before being put into use.
