Pneumatic conveying is an efficient and widely used method of material handling in the oil and gas industry. However, like any other system, it can also experience blockages, which can lead to costly downtime and maintenance. In this article, we will discuss the factors that can cause blockages in pneumatic conveying systems in the oil and gas industry and how to prevent them.

Material Characteristics

The first factor that can cause blockages in a pneumatic conveying system is the material characteristics. Materials that are sticky, cohesive, or have high moisture content can create build-up and blockages in the system. In the oil and gas industry, materials such as drilling mud, cement, and sand can cause blockages due to their tendency to stick together or become compacted.

Pipe Diameter

The diameter of the pipeline used in pneumatic conveying systems can also cause blockages. If the pipeline is too small, the material can become compacted and create a blockage. On the other hand, if the pipeline is too large, the material can move too slowly and settle, causing blockages.

Velocity

Velocity is the speed at which the material moves through the pipeline. If the velocity is too low, the material can settle and create blockages. If the velocity is too high, it can cause erosion of the pipeline and damage to the material. Finding the optimal velocity for the material being conveyed is important to prevent blockages.

Improper System Design

Improper system design can also cause blockages in pneumatic conveying systems. This can include incorrect placement of valves, elbows, and other components that can cause the material to slow down, settle or build up, leading to blockages.

Inadequate Maintenance

Regular maintenance of pneumatic conveying systems is critical to prevent blockages. Inadequate maintenance can lead to equipment failure or build-up of material, which can result in blockages. Routine maintenance of the system, such as cleaning, inspection, and replacing worn components, can prevent blockages and ensure efficient system operation.

Pneumatic conveying is a popular and efficient method of material handling in the oil and gas industry. However, it is crucial to consider blockage factors when designing and operating pneumatic conveying systems to prevent costly downtime and maintenance.
