ANSELM calculates the energy efficiency potential of the entire facility, addressing the key questions:
By how much (%) could the efficiency of each process unit be improved?
If improving the efficiency requires investment, would such projects be economically viable?
Are there any other units, where similar investment could yield a larger economic effect?
Lack of such key information leads to mistakes in strategic planning which cost many millions of dollars in long term.

ANSELM answers the main questions top management and shareholders have:
where to invest, how much, and what the economic effect will be

Akin to Carl Linnaeus, who classified the flora and fauna of our planet, or Dmitry Mendeleev, who described the fundamental relationships between chemical elements, our international team of scientists created ANSELM − a unique system of indicators and algorithms to identify and prioritize all ways to improve the energy efficiency and reduce emissions of any facility operating with heat exchange cycles − with highest economic viability.

With over 120 years of combined industrial experience and scientific research in energy efficiency optimization in the context of refining, our team is confident that no other approach used worldwide will match the output of ANSELM.

This is a breakthrough in improving energy efficiency and a reliable way to maximize your return from ESG investments.

Refinery production capacity: 140 000 barrels per day
Project description: Reconstruction of the heat exchange system made it possible to reduce the power consumed by the process of primary oil refining by 44.75 Gcal/h or 392 010 Gcal/year = 39 201 MTOE (metric ton of oil equivalent)/year

Energy consumption prior to project implementation:
957 380 Gcal/year = 95 738 MTOE (metric ton of oil equivalent)/year

Energy consumption after project implementation:
565 370 Gcal/year = 56 537 MTOE/year

Project description: Reconstruction of the heat exchange system made it possible to reduce the power consumed by the process of primary oil refining by 17.53 Gcal/h or 153 564 Gcal/year = 15 356 MTOE (metric ton of oil equivalent)/year

The integration of three new heat exchangers made it possible
to abandon the use of a furnace at the gasoline stabilization unit

Plant production capacity:
◆ ethylene 1 500 thousand tons per year
◆ propylene 525 thousand tons per year

Benefits and Features
For each compound device we identify breaks between current and potential minimal consumption. Break divided for 3 types of resources or area of optimization.

Breaks Diagram show difference in energy or money measurement units.

In this case we see that break for this compound device created by inefficient work of ovens heat exchange system

Input of electric equipment can be neglected and concentration only on 2 areas of equipment.

This approach leads to reduced implementation time to achieve maximum efficiency
For the plants included in the survey, a General map of energy efficiency projects is formed*
The potential for all units is broken down into a project map, according to the gap chart.
In the presented chart, the size of the rectangle characterizes the size of the effect from the
implementation of a particular unit project. Several projects in different areas of optimization can
be proposed for one unit. As we can see from the chart, only 11 projects from 63 (15% of the total)
cover 50% of the energy saving potential at the refinery.

As a result, the choice comes from the list of ready-made projects.

The set and number of projects may differ for other refineries.
Financial efficiency for each project
  • For each direction of efficiency improvement ANSELM automatically calculates economic indicators: IRR, NPV, DPP, PI.

  • This allows you to immediately cut off projects, the implementation of which is impractical, and focus on the ones with maximum profitability.

  • The calculation for each unit is performed taking into account the schedule of its repairs, the region, the cost of energy resources, etc.

  • As a result, an economically justified map of energy efficiency projects is produced.
