Information at a Glance

  • Material and energy balances are very important in an industry
  • The first material balances are determined in the exploratory stages of a new process, improved during pilot plant experiments when the process is being planned and tested, checked out when the plant is commissioned and then refined and maintained as a control instrument as production continues. When any changes occur in the process, the material balances need to be determined again.
  • The increasing cost of energy has caused the industries to examine means of reducing energy consumption in processing. Energy balances are used in the examination of the various stages of a process, over the whole process and even extending over the total production system from the raw material to the finished product
  • The aim is to increase production as well as minimization of wastes, emissions and toxicity at their source rather than treat them after its generation
  • Production Process includes consumption of raw materials, water, energy, elimination of toxic raw materials and reduction of the waste quantity, water consumption and toxicity of all emissions.
  • Energy consumption act is in place to regulate the performance of the Industrial Production
  • Mass and energy balances are coupled in order to use each in the most efficient manner possible.
  • Process energy is optimized by consideration of process heat integration, low- and high-temperature sources, mechanical systems  electrical systems, water, utilities, waste-to-energy opportunities, and facility energy integration. These compounds can be applied to unit operations, such as distillation, liquid extraction, drying, freeze crystallization and drying, crystallization, filtration, chemical reactors and so on
  • When designing a chemical process, a form of “double entry accounting”, evolved regarding materials processed and energy consumed. These two elements are always coupled and provide the designer with a convenient method to both design the process as well as double check and optimize the use of both materials and energy.
  • Across the chemical and petrochemical industry, safety, process optimization, energy usage, emission reduction and new product innovation drive advanced engineering and technology development
