Process pigging specialist HPS Product Recovery Solutions has produced a short video dispelling one of the most common myths about pigging – that “pigging systems are slow”.
Also known as liquid product recovery, pigging is an established technology that is used worldwide by process and FMCG companies. It’s used with many different products and processes, ranging from food, chocolates, wines and soft drinks, to cosmetics, paints, lubricants, solvents and many more. In short, almost any liquid or wet product that can be pumped can be pigged, says HPS.
Pigging works by using specialist projectiles (the ‘pigs’) to recover every last drop of useable product from pipelines at the end of batch runs.
The video not only demonstrates how quickly process pigs travel through pipelines, it also shows the HPS pig successfully recovering up to 99.5% of product from the line.
The design of the HPS pig enables it to have extremely high recovery rates, says the company, which it maintains even when travelling around 1.5 D bends. It’s not uncommon to see pigs reach 10 metres per second.
Properly implemented pigging systems offer many advantages while delivering a high return on investment (ROI) with rapid payback periods. And because the pigging process is extremely quick, interruption to operations is kept to a minimum.
