  • Numerical Simulation of Hydrodynamics and Cracking Reactions in the Feed Mixing Zone of a Multiregime Gas–Solid Riser Reactor
    Industrial & Engineering Chemistry Research, 2011
    Co-Authors: Hui Zhao, Abdallah S Berrouk, Chaohe Yang, Honghong Shan
    Abstract:

    A CFD simulation was performed to evaluate the performance of a novel multiregime gas–solid fluidized riser reactor that was designed to maximize the propylene yield from the catalytic cracking process. Simulation results of the industrial-scale riser reactor show the coexistence of different regimes in the reactor. Also, both the outlet product compositions and the reaction rate vectors indicate that the cracking reactions mainly take place in the Feed injection section. The product quality and distribution demonstrate the superiority of this novel process technology. The results of the CFD simulations are in good agreement with the test run results of a real industrial FCC reactor.

  • Economic and thermal feasibility of multi stage flash desalination plant with brine–Feed Mixing and cooling
    Energy, 2014
    Co-Authors: Majed M. Alhazmy
    Abstract:

    Improving the performance of MSF (multi stage flash) desalination plants is a major challenge for desalination industry. High Feed temperature in summer shortens the evaporation range of MSF plants and limits their yield. Installing a cooler at the Feed intake expands the evaporation range of MSF plants and increases their yield. Adding a cooler and a Mixing chamber increases the capital and operational costs of MSF plants. This paper presents thermal and economic analysis of installing a Feed cooler at the plant intake. The profit of selling the additionally produced water must cover the cost of the cooling system. The selling prices for a reasonable breakeven depend on the selected cooling temperature. The cost of installing coolers capable of maintaining Feed–brine mixture temperatures of 18–20 °C shows breakeven selling prices of 0.5–0.9 $/m3. These prices fall within the current range of potable water selling prices.

  • Multi stage flash desalination plant with brine–Feed Mixing and cooling
    Energy, 2011
    Co-Authors: Majed M. Alhazmy
    Abstract:

    Improving the performance of Multi Stage Flash (MSF) desalination plants is a major objective in the seawater desalination industry. Fresh water production rates from MSF plants depend on the evaporation range defined as the difference between the top brine temperature (TBT) and the bottom stage temperature. Lowering the temperature of the plant bottom stage elongates the evaporation range and increases the yield. A modified multi stage flash plant with brine Mixing and cooling (MSF-MC) is presented in this paper. Part of the brine leaving the plant is mixed with fresh seawater Feed then cooled to low temperature before it enters the bottom stage Feed heater. This MSF-MC features several advantages such as expanded evaporation range at the conventional TBT levels, reduced Feed pumping power, moderate levels of chemical treatment requirements and fixed fresh water production rates independent of seasonal seawater conditions. Operating with low Feed mass fraction minimizes the cooling load and reduces the cooler size. An improvement in the yield by 1.18%–1.4% for every 1 °C reduction in the plant bottom temperature can be achieved with MSF-MC compared to conventional MSF systems.
