4 Energy balance for ammonia production 4.1 Thermodynamic minimum The minimum consumption for the production of ammonia from methane, air and steam, cal- Ammonia (NH 3) is one of the most synthesised chemicals worldwide, having widespread use in energy concepts and production of explosives, pharmaceutics, fibres, plastics, paper and other essential chemicals and products. This will make renewable energy generation more efficient and usable for the long-term. Currently, the Haber–Bosch process produces ammonia at an energy cost of 8 MWh/tonne and 65% energy efficiency, accounting for 1–2% of global energy consumption and more than 1% of global greenhouse gases. endstream endobj 86 0 obj <>stream The SOE is ENERGY AND CARBON BALANCE OF AMMONIA PRODUCTION FROM BIOMASS GASIFICATION Dr. Paul Gilbert and Dr Patricia Thornley Tyndall Centre, Department of Mechanical, Aerospace and Civil Engineering, University of Manchester, M60 1QD, UK ABSTRACT: This study uses life cycle assessment (LCA) tools to provide energy and carbon balances for the production of ammonia from biomass … The formation of ammonia from hydrogen and nitrogen is a reversible reaction, as shown in equation [2]. The reaction makes ammonia at atmospheric pressure and 45°C – significantly lower than the high pressure and hundreds of degrees needed for the Haber–Bosch process.

The “Global average” data is from the IFA’s ongoing benchmarking project, which collects efficiency metrics from active ammonia plants worldwide. Energy management also decreases waste and emissions which may be expensive to monitor. Besides new investments, revamping investments are also included in the modeling and the development of the production stock is accounted for. Although the specific energy … Overall, ammonia seems a very promising energy storage medium and carrier, but most of the ammonia produced globally is used for fertilizers and comes from the consumption of about 2 percent of the world’s energy which leads to about 1.6 percent of global CO 2 emissions. Ammonia production has increased steadily since 1946 (Figure 2), and it is estimated that the annual production of ammonia is worth more than $100 billion, with some plants producing more than 3,000 m.t./day of NH3.

There are numerous large-scale ammonia production plants worldwide, producing a total of 144 million tonnes of nitrogen (equivalent to 175 million tonnes of ammonia) in 2016. This is far easier to achieve than the 700 bar required just to compress hydrogen, and even cryogenically cooled liquid hydrogen only manages an energy density of 10 MJ/L. Most of the fuel for ammonia production is consumed in the primary reformer (about 78%) and the remaining in auxiliary boilers. �QB໨ Therefore, with green ammonia production, renewable energy can be stored and reused for power generation at consumption points. )ݿ�dHG�y����″��v��z���H�.��z�в�2|���_��^Ōt��D���C��Xt8�~a���I��QH�����sp���`2��r�b9�����QH���]����C5%��,:�^ �����z�p!��4�e����B�_.��@*�f�pC�����T2+`J �G>�`ms\��8�I_ޱ���=t�������":��S��n�H��ڪ�^�G'2:����L'�ߢ�[��I�ԧE-LJ�cO[�B0-}y�aYX�j��Ӗ�D �&�qv^X�i���b,�#A�0��ɵ��`!hn'�A'��bo',8�9����A~0{��x���پAc�~8cqo��ޛr�����L֋[��ζ�\8\D�t.�!a�����_�W�H^��� �F�*�tH�o�~{,��yIp`���g����� �:���pQ�~�>�]׵�Q�y}b� x8���*��q�2�`���c'��#b�Y" ~�`ʷO��Ts^J��$gG�N�������O����ν��sm"�G��s۵W�l��%x�̺�|B�|2��,�����J�L;�xtPP���ϟ��� �����O����"� mG�kO�jH~:������aS���w�x��F�e��xe�b��>.�9�J��b�I����;G�.���]���|��%�P�L��m�FBN'�o?��:"OuXȬ�$GD���z��A]�w��@/Н���vu� More than 80 percent of energy consumed in the nitrogen fertilizer industry is actually for manufacture of ammonia.

This process also requires large energy consumption (Kroschwitz & Howe-Grant 1995b ). This opens doors to ammonia production with low energy consumption and reduced greenhouse gas emission. Finally, in the fourth part, this approach is applied to the modeling of energy efficiency improvements and CO2 emission reductions in ammonia production.

In the steam reforming process, the theoretical minimum energy consumption for ammonia manufacture is approximately 19.4 GJ/t NH 3 (LHV). As per IFA 2008-2009 summary report on energy efficiency and CO2 emissions in ammonia production, energy use for best available technology (BAT ) for natural gas based plant is 28GJ per t ammonia and energy use by best practice technology (BPT) is 32 GJ per t ammonia. From 1990 on, some data from recently built plants are shown with figures between 6.8 and 7.4 Gcal per ton of ammonia. Ammonia is one of the most highly produced inorganic chemicals. 4 Coal as feedstock for hydrogen production in ammonia plants is predominantly used in China and is generally characterized by high energy consumption and CO 2 emissions. Energy content of ammonia The CSIRO paper begins by defining ammonia as either having an energy content of 5.17 MWh per metric ton if used as a direct fuel (based on ammonia’s lower heating value, LHV), or having a hydrogen energy content of 5.91 MWh/ton if cracked back into hydrogen before use in a hydrogen fuel cell (based on hydrogen’s LHV). Since ammonia production accounts for some 87% of the industry’s total energy consumption, the fuel and feedstock used to produce ammonia are by far the main energy requirements. It is also one of the industry’s main sources of GHG emissions. Pure ammonia can be liquified relatively easily, requiring just 10 bar pressure at room temperature, to give ammonia an energy density of 14 MJ/L. %%EOF hޜ��r�8ǟ`�A����e�f:��&$��dC�t��. ���/={NOax��b��_��0���ś��ȱ�D����Nz��?��+u��L��a��Ϳ�y��싘 •Energy consumption by ammonia production is the largest in the chemical industry.
