What is a heat balance sheet used for?
Thread Content
In the calculation of the process flow, in addition to preparing a material balance sheet, a heat balance sheet is also required. Is this heat balance sheet mainly used to calculate the consumption of steam and cooling water? ? Are there any other uses?
Heat balance tables are not just about the consumption of steam and circulating water; some also reflect the temperature of the materials, as well as the measures that need to be taken at certain temperatures, such as insulation and protection against burns. Most chemical reactions involve changes in heat, and a calorimeter can show the amount of heat change throughout the process.
According to the response from the second floor, there should also be information on fuel consumption and the amount of water used in the cooling cycle, and it may even relate to the construction of cooling towers later on.
Thermal balance calculation should compute energy consumption to measure the energy use of a device.
Based on the explanations from the three experts upstairs. Basically, it explains the role of energy balance clearly
These are also the heat load results for each heat exchanger; based on these, the area is calculated to determine the dimensions. In petrochemical and refining plants, in addition to the heaters/coolers for steam and cooling water, there are many heat exchanges between different materials, in order to make full use of heat (or cold energy); to use modern terminology, it’s about reducing carbon emissions. I remember that for the feed to the ethylene plant, 11–13 heat exchangers were used before the material reached the methane tower; the design of these heat exchangers was based on thermal balance.
Well, I’ve learned about it – are there any such examples?
Yes, are there any examples of heat balance calculations?
