  • A chemical heat pump (CHP) utilizes reversible reactions involving significant endothermic and exothermic heats of reaction in order to develop a heat pump effect by storing and releasing energy while transforming it from chemical to thermal energy and vice versa. In this paper, the authors present a mathematical model and its numerical solution for the heat and mass transport phenomena occurring in the reactant particle bed of the CHP for heat storage and cold/hot heat generation based on the CaO/Ca(OH){sub 2} reversible hydration/dehydration reaction. Transient conservation equations of mass and energy transport including chemical kinetics are solved numerically subject tomore » appropriate boundary and initial conditions to examine the influence of the mass transfer resistance on the overall performance of this CHP configuration. These results are presented and discussed with the aim of enhancing the CHP performance in the next generation reactor designs. The CHP can store thermal energy in industrial waste heat, solar heat, terrestrial heat, etc. in the form of chemical energy, and release it at various temperature levels during the heat-demand period.« less
  • Conventional processing schemes for desulfurizing, drying, and separating natural gas liquids from natural gas streams require treating the gas by a different process for each separation step. In a simpler process, based on the University of California, Berkeley, Sulfur Recovery Process (UCBSRP) technology, hydrogen sulfide, propane and heavier hydrocarbons and water are absorbed simultaneously by a pol(glycol ether) solvent containing a homogenous liquid-phase catalyst. The catalyst promotes the subsequent reaction of hydrogen sulfide with added sulfur dioxide to produce a high-quality sulfur product. Hydrocarbons are separated as two product streams with the split between propane and butane. This new processmore » offers an overall reduction in both capital and energy costs.« less
  • This work presents a new mechanism for the evaporation with simultaneous particles emission mechanism in the evaporation chain as new channels opened to high excitation energy regime of the compound nucleus. The probability of multiple simultaneous emissions is determined based on phase space approach. A Monte Carlo simulation is employed to compute the final average yield of emitted particles after the decay chain. The neutron, proton, alpha and fission yields are obtained and compared to the conventional calculation with sequential simple particles emission and the relevance of the different channels in competition is also analyzed.
