Welcome to our introduction to the world of pigging technology, where we explore the advancements that have revolutionized this crucial aspect of delayed coker maintenance over the past two decades. We’ll start by taking a detailed look at a standard pigging truck and its components, along with recent technological improvements that have enhanced efficiency and effectiveness.
Over the past twenty years, pigging technology has evolved significantly, shaping current practices and paving the way for future innovations. One major advancement is the minimization of water discharge. Various strategies have been developed to reduce and reuse water during pigging operations, including additional treatment steps that make water management more sustainable. Modern pigging units now have the capability to handle multiple passes simultaneously, processing two, four, or even eight passes at once, thanks to powerful pumpers.
The improvements in pigging technology are also supported by the use of advanced materials that enhance durability and performance, making operations more efficient and reliable. Hydraulic drive mechanisms have become a staple in modern pigging systems, providing improved control and power during operations. Innovations in pig design and appendages have further enhanced their cleaning capabilities, allowing them to tackle stubborn residues more effectively.
Automated valves play a crucial role in quickly changing pigging directions and help monitor and manage pressure and flow during operations. Real-time process data readouts provide operators with precise information on the pig’s location within the heater, which is especially important in heaters with multiple tube diameters.
We also delve into the historical context of pigging development and explore various alternative methods such as steam air decoking, turbine cleaning, and sand/grit blasting. While these alternatives have been explored, they often fell short in certain areas, making modern pigging technology the preferred choice for many operations.
By the end of this video, you’ll have a thorough understanding of the advancements in pigging technology and how they’ve transformed the refining industry. Join us as we delve into the details, share best practices, and highlight the innovations that make modern pigging systems more efficient and effective than ever before.
