With an Energy Audit, we initially want to gain an understanding on the energy flows
at the production site – from the main counters to the relevant energy consumers. An Energy Audit also often needs to meet specific requirements, like in the context of the EPA (Energy Policy Agreement) between Government and industrial companies with, for Belgium, an energy consumption exceeding 0,1PJprim. CEE has the necessary recognitions t perform these audits. First of all, we lists the possibilities for energy efficient improvements with the interested parties based on, amongst others, own insight, brainstorming sessions and working group meetings. The result of an Energy audit,
in addition to a thorough understanding of the energy management of a company, represents a list of concrete improvement projects with a calculation of the investment on the one side, and the economic return on the other. Following an Energy audit, we can proceed with the Basic Engineering of selected most attractive projects. This may be accompanied by Energy Monitoring, to supplement the available data. In this way we can confirm after the build, the assumptions that were made in the audit phase.

Feasibility study

A feasibility study zooms in on the technical and/or financial feasibility
of an project. We conduct this type of study mostly when a company suspects that a particular investment or change could lead to added value, but the complexity of, or a lack of familiarity with the technology makes the feasibility analysis more difficult.  

Different scenarios will be at the base, with the same intended purpose, being increased energy efficiency in thermal processes. These are then compared with each other based on technical and financial criteria, which are determined in consultation with the client. Finally, we generate a capex-opex model for the best scenario, with which a sensitivity analysis can be prepared in function of various input parameters and assumptions.

After a feasibility study, we proceed with the Basic Engineering of the investment project to increase the accuracy of the capex-opex calculation and the results.

Energy studies

An Energy study is carried out when a customer wants to build a new production plant or extend an existing production facility. The purpose of the Energy study is to determine whether the best available techniques (BAT – EMIS / BREF – EIPPCB) are used in the design for the project concerned. Since 2004, such an energy study is a mandatory annex to the application for authorisation for a new establishment with a total annual energy consumption of more than 0.1PJprim, or for modification of an existing installation with an additional consumption of at least 10TJprim.

In addition to a formal exercise, it is an excellent opportunity to look into the energy efficiency of the extension/new construction. The possible optimizations are included in the design from the start of the study (first time right).

Energy monitoring

CEE makes extensive use of measuring instruments to support the study and analysis work on existing installations quantitatively.  To measure is to know. But measuring is not always easy. That is why we are investing in it on a continuous basis.

The table below shows the type of measurements that we can simply install on existing installations, to record energy flows remotely.

We excel in the simultaneous measurement of a large number of parameters on complex plants, and in the analysis of measurement results that are extended in dimensions and time.

Process Analysis

Industrial energy flows are complex. Besides the fact that they can occur under various forms (heat, cold, electricity, fuels ...), it is also about various media (air, flue gases, hot water, steam, thermal oil, products, etc.).  At CEE, we have a team of process specialists that can model all the possible combinations of energy flows, including conversions, exo- and endothermic reactions, using Aspen. A thermodynamic model is firstly made of your existing installation, and validated as much as possible with measurement data. This can then be used to simulate energy optimizations in real time, or to analyse anomalies and limitations in existing installations.

Pinch analysis is a methodology that allows you to calculate and visualize the minimum heat and cold requirements of a production process. 

This minimum is achieved by optimum heat integration within this process.

Comparison with the real situation allows us to quantify the thermodynamic maximum savings potential. Practically viable interventions in the process-integration and operations, and combinations of these, can then be compared with this maximum. The selection of the profitable projects then follows.
