A successful cleaning chemical formulation process for hydrocarbon transportation pipelines has been developed and applied in pipelines in the U.S. Case studies are included in this article.
Pigs have been squealing in pipelines for decades. A lot has changed, however, since the first modern-day pipeline pigs were introduced in the early 1940s. Many would cite the development in recent years of smart pigs, also called inline inspection (ILI) tools, as the biggest change. These pigs, which use sensors and computers to accurately inspect and analyze pipeline conditions and problems, do represent a vital improvement in the technology.
There are two types of pipeline cleaning programs available. One type is referred to as mechanical cleaning (the running of mechanical pigs dry) and is the answer most mentioned when asked, “Do you clean your pipelines?”
Pigging technology today has been advancing exponentially, and what we mean by technology is not so much the hardware side but the application.
