Rütgers enables saving by outsourcing their demin water production

1. The Challenge: growing needs due to expansion

The tar processing company Rütgers in Zelzate (Belgium) will increase its production of phthalic anhydride by fifty percent in 2014. This means 14,000 tons per year extra phthalic anhydride. Because of the rapid expansion Rütgers needs more demi water to handle higher production needs by september 2014.

The next question Rütgers asked themselves was if they should upgrade the existing water treatment plant, which was built in the 80’s to meet the forecasted growth and demand over the next years or build a new water treatment plant.

The existing units were not functioning properly and the operational costs were enormous. 

When Rütgers approved to upgrade its production of phthalic anhydride, they knew it would be a costly project. Rütgers decided to outsource their water operations so they can focus and invest on their primary business more effectively. 

2. The Answer: outsourcing to Induss 

The solution Induss’s Design Build, Finance, Operate (DBFO) industrial and commercial water outsourcing services. It provides an economical alternative that allows Rütgers to focus on their capital, resources and core business rather than on their water systems. The related technological and infrastructure investment is also made by Induss, saving Rütgers a significant non-core cost (CAPEX). 

The outsourcing of water services requires teamwork and input from both companies:

  • The scope of work. Both companies reviewed the current operation of water assets.
  • Rütgers’s goal: Current need demin water for a steamquality of 40 bar. But Rütgers plans in the future to install a steam turbine generator which generates electricity for in-house consumption.
  • Induss challenge: Prior to determine whether which quality of water was needed, an investigation was carried out into the plant’s water assests. The purity of demin water is critical in maintaining steam quality.
  • Solution:
    • Phase 1: A double pass RO (container mounted) to meet the need of the current water quality
    • Phase 2: The final installation of an EDI unit is planned when the steam turbine generator will be commissioned. Throughout the design review phase, all interconnecting piping, electrical connections etc were provided so that this last treatment step can be built in a simple and efficient way.

 3. The Benefits

Outsourcing eliminates operating and expense risks. Induss focused on the needs of Rütgers. By phasing the project in 2 parts, the TCO was lowered and no excess water is wasted. The day-to-day risks of operating in climates of increasingly stringent regulations and user demands for improved service, are now transferred to an experienced operator - Induss. 

As technologies become more sophisticated, operations become more complex, and the risk of non-compliance increases. Utility costs typically increase faster than general inflation, but cost guarantees from an experienced operator can help to manage costs over time. 

Rütgers reduced it’s Total-Cost-of-Ownership (TCO) by choosing a DBFO solution. They opted to invest in the production side of their businesses, not the utility side.
