LDPE Plants and Vibrations

LDPE Plants & Vibrations

How can we help to improve your LDPE plant?

Running highly valuable processes under technical challenging conditions is not easy. However, with expertise and strategy, it can offer incredible potential. This site gives you an overview about our services and experience around the field of LDPE plants.

LDPE Plants & Vibrations.

In order to ensure a safe and efficient operation of LDPE plants, a high level of expertise in sound and vibration engineering is required. Reasons include, e.g. operating conditions in LDPE processes with a discharge pressure of up to 3,500 bar, structural specifications that makes vibration mitigation measures even more challenging and typical operating mechanisms of a reciprocating compressor. Due to these conditions, vibrations and pulsations have a considerable influence on your assets and may cause unplanned downtime with loss in revenue streams.

Hence, the safe operation of LDPE plants is a challenging engineering task and has top priority!

There are two states where special care about sound and vibration engineering is essential:

  • Commissioning of a new plant
  • Revamp of existing plants 

No matter whether it is the commissioning of a LDPE plant or modifications to existing plants. The unique composition of all components create an acoustic model, which shows an individual behavior. Due to an unfortunate operation condition resonance effects can occur which trigger destructive forces within the piping system.

With experience from more than 500 completed projects and more than 20 years, we provide the required expertise you need in this challenging industry.

Optimize LDPE Plants – New Approach.

Increasing volatility in industry, not least due to the ongoing corona pandemic and constantly rising cost pressure while maintaining high safety requirements, challenges operators and manufacturers of LDPE plants to take action for optimization and a fast reaction time when problems occur.

As KÖTTER Consulting Engineers, we have been able to use our experience, primarily in troubleshooting projects, to gain a great reputation as experts for sound and vibration engineering in the LDPE industry. However, in recent years we have also demonstrated the value of defining a vibration optimization strategy for your assets in advance, which can reduce the costs for unscheduled downtimes tremendously. The improvement of the plants reliability is a key factor for commercial success.
