Key Technology to Reduce Carbon Footprint in Industrial Sector

How much did that suit cost you? Of course, you can get that from the receipts. Nevertheless, everything in any space you are in now has an environmental cost that isn’t obvious. For instance, the United Nations Environment Programme (UNEP) estimates that the creating a pair of jeans consumes 3,781 liters of water.

Such statistics underline the need for urgent action. The deadline for meeting the Sustainable Development Goals is approaching, so it is imperative that industries fast track their efforts to reduce carbon footprint. Everyone seems to have realized that achieving the SDGs will remain a mirage if the industrial sector contribution to the current predicament is not addressed thoroughly.

How Industrial Operations Contribute

About 25% of greenhouse effect emanates from the industrial sector, either directly or indirectly. Construction, food processing, mining and manufacturing are key industrial subsectors where diverse processes result in direct CO2 emissions. Power and heat require a lot of fossil fuel combustion. Production of cement, steel and other materials essential to the sector also contributes to substantial emission. The industrial sector also contributes to indirect emissions i.e. those associated with offsite operations.

Direct industrial emissions occur when you run the computer, operate industrial facilities, and cool the building and so forth. Other sources of direct emissions are industrial process leaks, chemical processes and production process petroleum. Power plants for industries produce indirect emissions.

What is ARANER doing?

Although the industrial sector continues to contribute significantly to emissions that affect human health and the environment, factories and businesses apply different methods to reduce carbon footprint. In recognition that improved energy efficiency in industries cuts greenhouse gas emissions and minimizes costs, we are constantly developing energy efficiency measures for different subsectors.

Efficient Process Cooling– Industrial Refrigeration

Industrial refrigeration can be defined as the provision of cooling energy to large-scale processes. It embraces a wide range of temperatures, inherent to the purpose it serves, the size of the installation, the equipment’s working conditions, etc. Industrial refrigeration shares common traits with air conditioning: they both have a working fluid and they integrate similar components such as compressors, heat exchangers or pumps.

TIAC CASE STUDY Saudi Aramco, which is well known as the biggest Oil & Gas Company in the world,increased its power output in 21 % thanks to the implementation of a gas turbine inlet air cooling system specifically designed for their requirements by ARANER. This meant a recovery of more tan 149 MW of extra power, with a very low capital cost thanks to the turbine energy output increase with air cooling technologies.

Nevertheless, the most significant difference between them is the scale that it comprises. For air conditioning, the system is usually more standardized, as it is often an extended solution that can be installed like a plug play package. In the case of industrial refrigeration, the solution is often tailor-made and consequently the design is a complete package.

This is a renowned ARANER solution for reducing industrial carbon footprint. It is applicable in numerous industries including food & beverages, pharmaceutical & chemical, data centers and electricity production. Considering the unique challenge of power generation in respect to carbon emissions, we will delve into electricity production a little more below.

Supporting Efficient Power Generation

Our desire to improve power generation is in line with global efforts towards improved industrial efficiency and reduced emissions. Natural gas is still the primary energy source according to data from U.S. Energy Information Administration. That means that the increasing energy demand continues to expand natural gas exploitation. In line with this need, efforts to improve energy efficiency in power generation have gained more traction in recent years.

We pride in our ingenious power output enhancement solution: Turbine Inlet Air Cooling (TIAC).  TIAC is a group of technologies and techniques whose objective is cooling down the intake air of the gas turbine and ultimately power output augmentation. This technology is widely used in hot climates with high ambient temperatures that usually coincide with on-peak power demand.

Since global energy use is increasing at a record rate, energy efficiency and effective asset utilization have become two of the most critical issues in power generation. TIAC maximizes the power output and improves the energy efficiency of both new and existing combustion turbine power plants for combined-cycle, simple-cycle and cogeneration.

For industries that generate own power, TIAC can help achieve both economic and environmental benefits. On the economic front, the technology increases the annual average output MW and helps realize savings because no additional turbine is necessary. If combined with thermal energy storage (TES) to form TESTIAC, the effect can be even more satisfying.

Conclusion

To avoid further climate change consequences, the world must reduce greenhouse effect by 50% by 2030. We are doing our part by focusing on industrial energy efficiency through modern technologies.

We have several examples of successful TIAC applications, one of the recognizable ones being the Jebel Ali Power Plant in Dubai. With thorough analysis of climatic and other project conditions, we can improve your industry too. Consider contacting us for TIAC and other industrial refrigeration solutions to reduce carbon footprint and achieve more savings.
