Special Issue Information

Dear Colleagues,

The “Sustainability” journal has an open call for original research papers for special issue on “Sustainable and Green Chemical Engineering Technologies”. This special issue serves as a platform for reserachers and engineers throughout the world to exchange and disseminate new ideas to address the theoretical and practical issues of sustainable production in the Chemical engineering technologies. We aim helping societies become more sustainable in several ways by preventing/minimization of the production of waste and emissions, while increasing efficiencies in the use of energy and resources. With a continuing transition to a more sustainable energies from fossil fuels, there is an immediate need of accelerating research & development in these areas to participate in a transition to clean, low-carbon energy systems. To do so, a rate of progress toward increased efficiency, de-carbonization, greater fuel diversity and lower emissions/wastes need to be greatly accelerated.

We invite researchers in this field to submit their original papers for inclusion in this special issue. Suitable submissions could address any areas of sustainable and green technologies in the chemical engineering including but not limited to:

  • Clean production in chemical industries
  • Sustainable development & consumption
  • Clean or low emission energy production technologies
  • Waste reduction/transformation/reuse/utilization

The journal welcomes submissions on the more specific topis of:

  • Hydrogen energy production, storage and transportation
  • Biofuels and bioenergies production
  • Bioenergy processes and utilizations
  • The role of biomass utilization in the circular economy
  • Decarbonization of fossil fules

Waste minimization in reactor design is an effective approach for pollution control, when compared to the traditional practice of the end-of-pipe treatment. Reactor degree of backmixing and operating conditions are important factors that determine the performance of chemical process, including environmental impact. For the purpose of waste minimization, two modeling methods were used for simulating the performance of the acrylonitrile production reactor, based on the ammoxidation of propylene. The effect of residence time, temperature, degree of backmixing on the steady-state propylene conversion, and production of waste were determined. The tanks-in-series model and the axial dispersion model were used to account for the degree of backmixing. The two main by-products in the acrylonitrile process are acetonitrile and hydrogen cyanide, which are both highly toxic waste. Extensive reactor backmixing reduces propylene conversion, especially at high temperature and residence time. Minimum acetonitrile production is favored by low residence time, high to moderate temperature, and no backmixing. Minimum hydrogen cyanide production is favored by low residence time, low temperature, and no backmixing. At 450 °C, the percentage of increase in the selectivity of acrylonitrile, with respect to hydrogen cyanide at plug-flow reactor conditions, as compared to a continuous stirred tank reactor, is 87.1, 74.3, 50.9, 30.4, and 12.4% at a residence time of 1, 2, 4, 6, and 8 s, respectively. The reactor degree of backmixing and operating conditions are important factors that affect the environmental friendliness of the acrylonitrile production process. Full article
