You’ve likely heard the term high integrity pressure protection (HIPPS) before if you’re an industry worker. Of course, a safe working environment is always important. But with HIPPS, you get extra reassurance and protection from your working environment.
But what does HIPPS mean?
Are there any other benefits to it? If so, what are they? Let’s take a look at HIPPS in more detail and figure out how it can benefit you and your business.
What is high integrity pressure protection?
High integrity pressure protection (HIPPS) is a technique in industrial equipment to protect against dangerous pressure. Traditional equipment safety systems have used relief devices to deal with excessive pressure. These allow fluid, under pressure, to escape into an emergency reservoir.
This can result in environmental contamination and be extremely costly for companies to manage over time. HIPPS prevents excessive pressures from building up in the first place. This eliminates the risk of pollution and costly repairs and replacements. In addition, it’s safer and more cost-effective than traditional methods. High integrity pressure protection is not new: Some forms of high integrity pressure protection are not new.
For example, An aircraft fuel tank uses since at least 1944 and as early as 1925 on stationary equipment such as pumps or compressors. On the other hand normal operating conditions are not expected to create dangerous pressures.
A typical modern application would use two stainless steel vessels that act like hydraulic accumulators.
It absorbs any excess pressure through friction generated between metal surfaces; these forces cause movement inside one vessel while compressing liquid within another.
Safety and efficiency
In case of process or equipment failure, the operators can’t prevent fluid release by activating relief systems. The main purpose of a safety system is to avoid an unexpected event (to protect from a hazardous condition) . And therefore should be ready to work at any time.
Utilizing conventional systems becomes comparable to wearing a seat belt at high speed when analyzing these two aspects. Environment protection: relief systems release the service fluid to the atmosphere. HIPPS avoid fluid released out of the system, keeping the environment free of emissions.
Process efficiency: There are no valves between equipment and vessel, reducing piping diameter, increasing flow rates, and reducing pressure drops inside the pipeline.
Operators don’t need to wait for a valve opening before starting up/stopping down a piece of equipment, thus saving valuable time.
Because vessels do not have valves installed, the vessels can be used for various processes without needing to be reconfigured every time.
This allows plant managers to switch processes quickly without having to worry about changing configurations manually and waiting for new approvals from authorities such as the fire brigade etc…
The four advantages above make HIPPS suitable for all industries where there is pressure , such as oil and gas engineering companies, petrochemical, chemical & pharmaceutical industry, etc…
Advantages of HIPPS over traditional systems
We use HIPPS instead of relieving devices and can work with almost any type of safety device or downstream equipment. In case of equipment failure, no hazardous fluid out of the system keeping the environment free from emissions. قواعد لعبة الدومينو They also have several other advantages such as Less maintenance, lower costs, higher reliability, smaller footprint, etc.
For example, a relief valve malfunction can cause a small amount of liquid to be released into the atmosphere, which may hurt the environment.
Yet, even if a system breaks down, the liquid will not escape into the atmosphere. In addition, high integrity pressure protection systems are more reliable than traditional systems and have longer service life because they don’t use mechanical parts, which wear out easily over time, leading to frequent breakdowns and repairs.
They also require less maintenance because they have fewer moving parts compared to traditional systems, so they break down less frequently, requiring less maintenance time for servicing them.
How does a pressure management unit (PMU) work?
A PMU is a system that provides protection against high pressure. It includes all of the components (control valves, sensors, and controls) necessary to detect a loss of pressure and initiate an automatic shutdown of process equipment in order to avoid loss of containment.
A high-pressure safety valve is frequently connected to the system and gas or vapor detectors/alarms to detect when loss of fluid or atmospheric pressure in chemical processing equipment may occur.
Once it detects low pressure and initiates an automatic shutdown, it can also isolate the affected section of equipment by shutting down isolation valves on either side.
In some cases, monitoring systems can provide real-time data to alert operators to malfunctions in their plants. This allows them to address these problems before they worsen.
Other benefits of using a PMU include protection against catastrophic failures of process equipment and environmental protection.
Since relief systems prevent gases and liquids from entering the environment via relief systems, many environmental agencies require companies to use them in order to comply with local regulations such as those governing air emissions and wastewater discharge.
Noncompliance with environmental regulations can even incur fines in some countries. كأس العالم للكريكيت 2024 Reliability: Because they monitor conditions continuously, rather than simply responding once certain parameters. HIPPS units help ensure more reliable operation at reduced costs over time because they prevent costly unplanned outages.
How does a discharge line monitoring valve (DLMV) work?
We installed monitoring valve in parallel with one or more discharge lines. If a leak occurs, it will become evident by an increase in pressure or vacuum within that discharge line, as shown below. Once a leak occurs, there is no longer any reason to prevent the flowing of hydrocarbons.
Therefore, there is no longer any resistance to flow through the DLMV, causing it to open and release liquid at high velocity causing rapid extinguishment of fire outside of the structure.
This process reduces damage to infrastructures such as piping and tanks, prevents injury or death of workers on site, limits environmental impact from discharged fluids, and allows for safer operation overall.
The main components of a discharge line monitoring valve are:
A discharge line monitor (DLM) is used for determining if there are leaks in fluid pipelines. A fluid pipeline can be natural gas transmission, oil, water, etc.
It has been estimated that about 2%–3% (about 1 billion gallons per year) of natural gas transmission in the United States alone leaks out without being detected by traditional methods such as using acoustic devices, which have limited range due to attenuation effect caused by long pipelines.
Benefits in comparison to standard discharge line monitor (DLLM) installations
- No need to install additional underground discharge line
- No need to install additional gas flare or flaring area
- Reduced environmental impact
Lower cost of installation Some of HIPPS advantages in comparison with other systems:
- The pressure sensor and control unit is inside a tank, allowing for increased safety and reduced maintenance costs
- The possibility of installing on tanks that already have an existing DLLM system. This allows for a phased approach in replacing old equipment. العاب علي الانترنت
- The possibility to be installed on tanks that already have an existing DLLM system. This allows for a phased approach in replacing old equipment.
- The product is independent of any technology (GPRS, GSM, etc.) and can therefore on both new and existing installations without requiring any changes.
