The role of pump technology in LOC prevention in the chemical industry

Preventing loss of containment (LOC) incidents is paramount for ensuring the well-being of employees and maintaining a safe work environment. This article explores the causes of these types of incidents and proposes preventive measures, with a particular focus on the role of pump technology in containment control.
 

1.  Loss of containment: impact and causes

Significance and impact

LOC incidents can have devastating consequences, ranging from environmental damage to severe health hazards for your employees and the surrounding community. The financial impact due to fines, cleanup costs, and downtime can also be substantial.

The goal of preventing loss of containment lies in protecting lives, minimizing environmental harm, and ensuring regulatory compliance. Effective loss containment strategies safeguard not just your immediate facility, but also the broader community and ecosystem.
 

Understanding the causes

Common scenarios that lead to loss of containment incidents include:

1. Corrosion and material degradation: over time, materials can degrade, leading to breaches in your containment systems. Using a pump without properly specifying the material compatibility can accelerate corrosion and lead to premature pump failure.
   
   
2. Mechanical failures: pump failures due to mechanical issues such as seal degradation, bearing failure, or impeller damage.
   
   
3. Operational errors: human error, including improper pump operation or maintenance. It is crucial that your personnel are adequately trained and follow standardized procedures.

 

2.  Mitigate loss of containment risks

Adopting best practices can significantly reduce the above risks. Specifically for pump technology, this includes:

1. Regular maintenance and inspections: perform routine checks and maintenance of your pumps and other containment systems to ensure they operate correctly and safely. Regularly assess the condition of pumps and containment systems to identify potential weaknesses.
   
   
2. Analyze environmental factors: consider the external environmental factors such as temperature, humidity, and potential natural disasters and the impacts they might have on your pumps and containment systems.
   
   
3. Use high-quality equipment: invest in high-quality, reliable pump technology that is designed to handle specific chemicals and conditions, especially within your primary containment facility. Ensure that the materials used in pumps and containment systems are compatible with the chemicals being handled to prevent corrosion and degradation.

Or if you want to start from the materials of construction, use the process materials guide to get an overview per material and the chemicals it is compatible with.
 

Implement engineering controls and safety measures

Engineering controls are essential to enhance the safety and reliability of your containment systems. These controls include:

1. Secondary containment systems: install secondary containment systems such as bunds and drip trays to capture any leaks or spills from primary containment systems.
   
   
2. Pressure relief devices: use pressure relief valves and rupture discs to manage overpressure situations and prevent equipment failure.
   
   
3. Automated shut-off systems: implement automated shut-off systems that can isolate pumps and other equipment in the event of a detected failure. This helps to minimize the risk of hazardous material spills.

Train and educate your personnel

Training and education are cornerstones of preventing loss of containment incidents. Your personnel should be well-versed in:

1. Proper operation of equipment: understand the correct operational procedures for pumps and other containment systems.
   
   
2. Maintenance protocols: follow standardized maintenance protocols to ensure equipment remains in optimal condition.
   
   
3. Emergency response: be prepared to act swiftly and effectively in the event of an LOC incident, including the use of personal protective equipment and emergency containment measures.

 

3.  Reduce LOC risks with the right pumps 

Implementing advanced pump technologies designed for high reliability and durability can significantly mitigate risks.

There are five key features you should look out for in your chemical pumps:

1. Seal-less design: many chemical processors prefer double diaphragm pumps over centrifugal pumps for chemical transfer as centrifugal technology relies on mechanical seals, whereas double diaphragm pumps have a seal-less design.
   
   Mechanical seals typically wear out faster than diaphragms and when this seal fails, the fluid will leak out of the pump casing along the rotating shaft. Depending on the fluid you pump, the leak could be hazardous or polluting to the environment or dangerous for your colleagues.
   
   
2. Leak containment: diaphragms are a step-up compared to mechanical seals, but they will not last forever. When a diaphragm in a pneumatic pump fails, the chemicals can enter into the air valve and disperse through the muffler, potentially harming employees.
   
   Fully electric pumps do not need a muffler. So when a diaphragm fails, material is contained inside the pump, ensuring no loss of containment.
   
   
3. Corrosion-resistant materials: you need a pump that is not only compatible with the chemicals being processed, but one that is also capable of handling solids and abrasive material without causing increased pump wear and potential blockages.
   
   The selection tool and materials of construction guide mentioned above are great starting points.
   
   
4. Clear flow path: it’s common for material to contain particulates in suspension, and you need a pump that can pass the material with ease. A clear flow path with no internal obstructions makes your pumps less prone to clogging by solids.
   
   
5. Automated monitoring systems: advanced pumps often come equipped with sensors and IoT integration that allow for real-time monitoring of pump performance. These systems can detect anomalies early, enabling preemptive maintenance and reducing the likelihood of failures.
   
   A built-in leak detector is a must for chemical pumps to immediately identify a problem as soon as a leakage occurs. Be sure to select a pump that will automatically shut off. This is a crucial feature to keep your plant personnel safe.

 

Create an effective response plan

Even with preventative measures in place, it's vital to have a robust response plan for LOC incidents.

This plan should include:

• immediate containment strategies,
• emergency response protocols,
• and post-incident analysis to prevent future occurrences.

Conclusion

In the chemical industry, containment control is critical for ensuring safety and environmental protection. Advanced pump technology plays a crucial role in mitigating these risks.
