NA 140 "Procedure for Enhancing Energy Efficiency in Chemical Plants – Contribution of Automation Engineering" (Version: 01.06.2012)

The attention given to the issue of energy efficiency in the media, economy and politics has increased in recent years. The chemical industry also faces the important task of continually reducing the consumption of energy in specific areas.

Process engineering measures such as heat integration and efficiency improvements are without a doubt among the most well-known measures for enhancing energy efficiency. However, increasingly complex processes as well as heat and material coupling between several plants mean that the challenges faced by automation engineering continue to grow. Since the chemical industry has expanded its activity in the topic of energy efficiency in recent years, remaining potential can mainly be identified and realized through interdisciplinary approaches. Automation engineering contributes substantially to energy efficiency in this respect. The NAMUR working group, AK 4.17 "Energy efficiency", has compiled a NAMUR worksheet to develop and illustrate the contribution of automation engineering to energy efficiency. The procedure employed for the analysis of efficiency potential is universally valid and is supplemented by practical examples drawn from automation engineering.

The worksheet pursues the following objectives:

  • The illustration of a universally valid procedure for determining potential and measures for enhancing energy efficiency through the targeted use of automation engineering.
  • Support for the identification and quantifying of energy efficiency potential based on checklists
  • Illustration through concrete approaches and practical examples for typical process units in the chemical industry
  • Indication of further references for practitioners.

The target group of this worksheet are employees of companies in the process industry. They should have an engineering background and be responsible for the development and implementation of measures for the improvement of energy efficiency.
