6. How to Reduce Clean in Place (CIP) and Downtime in Liquid Processing

CIP systems play a vital role in ensuring the cleanliness of processing equipment, preventing bacterial contamination, as well as maintaining the integrity of the entire system. The necessity for CIP systems intensifies significantly when pipelines are shared.

CIP technology has many benefits to companies that process liquids. It enables the removal of bacteria, chemicals, and biological residues from processing equipment without having to dismantle the equipment.

This article looks at the role of CIP in hygienic, sanitary and process industries, spanning food and beverage, cosmetics, homecare, and so on. It also delves into how HPS pigging systems can make the CIP process easier, quicker, and more efficient.

Essentially, CIP and pigging go hand in hand. Because the HPS pipeline pig reclaims so much product from process pipelines, this results in reduced cleaning, water usage, and resource required. Therefore, there’s less work for a CIP system to do.

Pigging a pipeline before CIP, offers a wide range of additional advantages, thoroughly explored within this article.

5. Raw Price Inflation Still a Problem for Paint and Coatings Manufacturers in 2022

This article was our most popular pigging blog article in 2022. It’s now sitting in the number 5 position.

During 2022, paint and coatings manufacturers contended with substantial inflation in raw material costs.

Among them, manufacturers faced soaring prices for crucial raw materials like solvents, resins, and pigments, all experiencing notable increases in cost.

These increases were largely due to the huge increase in oil prices. At the time, oil prices skyrocketed by over 70%, reaching a peak of more than $113.94 (£86.81) per barrel, marking the highest point since 2014.

Alongside this, paint and coatings industries encountered additional pressures such as rising energy costs, the negative impacts of the COVID-19 pandemic as well as the effects of Russia’s invasion of Ukraine.

An effective way to offset these increasing costs and boost the bottom line is my implementing HPS custom pigging systems.

Explore the blog to delve deeper into the challenges facing paints and coatings manufacturers and how pigging systems can help.

4. How to Prevent Aeration During Liquid Processing

This blog article has climbed up three positions from 2022. It’s now sitting at the number 4 spot.

This educational article is particularly useful for companies dealing with liquid products susceptible to foaming (such as detergents, shampoos, shaving gels) or those that would be compromised by coming into contact with air during processing (such as wine).

Products vulnerable to exposure to air during manufacturing pose significant risks for manufacturers if they become aerated. Aeration can disrupt or halt manufacturing processes, leading to delays and, in severe cases, requiring complete product disposal.

One of the most effective methods to prevent liquid from encountering air before a run, after a flush, CIP, or product changeover is to use an HPS double-pig pigging system.

Double-pig systems seal the product from air or gas in pipeline by using two pipeline pigs. The specialist system not only significantly reduces aeration (and foaming), but it removes residual water or cleaning fluids (typically up to 99.5%).

To learn more about preventing aeration, foaming or air contact in liquid processing, be sure to delve into this informative article.
