  • opportunities for low grade Heat recovery in the uk food processing industry
    Applied Thermal Engineering, 2013
    Co-Authors: Adam Harvey, David Reay
    Abstract:

    Abstract Energy efficiency in the process industry is becoming an increasingly important issue due to the rising costs of both electricity and fossil fuel resources, as well as the tough targets for the reduction in greenhouse gas emissions outlined in the Climate Change Act 2008. Utilisation of waste Heat sources is key to improving industrial energy efficiency, with an estimated 11.4 TWh of Recoverable Heat being wasted each year, a quarter of which is from the food and drinks processing sector. This paper examines the low-grade waste Heat sources common to the food and drinks processing sector and the various opportunities for the use of this Heat. A review of the best available technologies for recovery of waste Heat is provided, ranging from Heat transfer between source and sink, to novel technologies for the generation of electricity and refrigeration. Generally, the most economic option for waste Heat recovery is Heat exchange between nearby/same process source and sink, with a number of well-developed Heat exchangers widely available for purchase. More novel options, such as the use of organic Rankine cycles for electricity generation prove to be less economical due to high capital outlays. However, with additional funding provision for demonstration of such projects and development of modular units, such technologies would become more common.

  • integrated mineral carbonation reactor technology for sustainable carbon dioxide sequestration co2 energy reactor
    Energy Procedia, 2013
    Co-Authors: Rafael M Santos, Wouter Verbeeck, Pol Knops, Keesjan Rijnsburger, Yiannis Pontikes, Tom Van Gerven
    Abstract:

    Abstract To overcome the limitations of mineral carbonation that thus far have prevented it from becoming an acceptable route to sustainable CO 2 sequestration, a novel reactor technology that makes use of a Gravity Pressure Vessel is developed. The ‘CO 2 Energy Reactor’ applies the principles of process integration and process intensification to achieve the technological leap needed to make mineral carbonation industrially feasible. Its autothermicity, hydrostatic pressurization, vertical plug flow design and underground installation make it an appealing alternative to other CCS techniques. This work reports the technical details of the conceptual design, and studies the effect of process parameters on reaction characteristics (kinetics and conversion) and energy balances by means of mathematical modeling. The parameter sets (particle size, solids loading, pumping rate, and reactor dimensions) that ensure autothermic behavior, maximize carbonation efficiency and enable Recoverable Heat generation are identified.
