Contributing global CO2 mitigation by utilisation of food industry heat into smart Croatian DHS via Total Site heat recovery
The production of food, which is maintaining the energy metabolism in human, needs the considerable consumption of natural resources, mainly the coal, petroleum and natural gas. The statistics indicate on noticeable energy consumption in food industry: to produce 1 J of food energy 10 J of primary energy is required. The population growth and its food supplying are causing the annual energy consumption rise on 24 – 40%. On the other hand it leads to fast deterioration of surrounding environment owing to CO2, NOx, SOx, dust, soot and other industrial emissions. The steep rise of energy prices in recent years, as well as the necessity to curb carbon dioxide emissions, have intensified the need for solutions that are increasing energy efficiency in the food industry. Heat integration is a key tool for energy saving achieved by heat recovery in process industries. Energy saving has an important role in achieving a sustainable future development. Heat recovery at Total Site level can provide a considerable potential for energy saving. Use of excess heat can provide a way to reduce the use of primary energy and to contribute to global CO2 mitigation. The methodology can be successfully implemented in different industrial sectors such as in sugar production, ethyl alcohol, glucose, dried milk, tomato paste, oil and bottled goods. The utility levels supplied to the process may be a part of a centralised site-wide utility system as well as smart district heating systems. Process integration extends to the site level, wherein appropriate loads on the various steam mains can be identified in order to minimise the site wide energy consumption. Process integration therefore provides a consistent methodology for energy saving, from the basic heat and material balance to the total site utility system. It provides the utilisation of low potential waste heat for district heating systems. The paper is focused on allowing heat recovery for district heating needs of both new designs and as retrofits to existing sites to ensure fast, widespread and cost-efficient industrial deployment. Targets also be set for the utility loads at various levels (e.g. steam and refrigeration levels).
