Many Indian ammonia plants struggle with high feedstock prices. In order to survive in the competition from new plants in areas with low gas cost, many plant owners of existing plants have decided to revamp their plants to reduce the energy consumption and/or increase the capacity. New developments are needed in order to fulfil these needs of the market. This paper will highlight some of the de...
Abstract Four tri-reforming-SOFC system configurations are built with different off-gas recirculation methods (anode and burner recirculation) reformers (with heat exchange oxygen injections) to improve management. The systems modeled explore the effects of fuel utilization. It is found that type mainly affects maximum temperature in reformer while reforming methane conversion. max gradient sta...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
An integrated system of a microreformer and a carrier allowing for syngas generation from liquefied petroleum gas (LPG) for micro-SOFC application is discussed. The microreformer with an overall size of 12.7 mm × 12.7 mm × 1.9 mm is fabricated with micro-electro-mechanical system (MEMS) technologies. As a catalyst, a special foam-like material made from ceria-zirconia nanoparticles doped with r...
In this paper, a hybrid solid oxide fuel cell (SOFC) and micro gas turbine (MGT) power system is parametrically studied to evaluate the effect of different operating conditions. The SOFC/MGT power system includes SOFC reactor, combustion chamber, compressor and turbine units, and two heat exchangers. The effects of fuel utilization, temperature, and pressure are assessed on performance of t...
In this paper a mathematical model for the convection section of industrial furnaces (energy recovery) is presented. In the paper, method of heat transfer on the outside and inside of smooth and finned tubes in the convection section has been investigated. After review of the various models of heat transfer, an appropriate model was selected, and the software for calculating the amount of heat ...
In this work, we introduce a furnace-balancing scheme that generates an optimal furnace-side feed distribution that has the potential to improve the thermal efficiency of a reformer. The furnace-balancing scheme is composed of four major components: data generation, model identification, a model-based furnace-balancing optimizer and a termination checker. Initially, a computational fluid dynami...
Fuel cells have been recognized as a feasible alternative to current IC engines. A significant technical problem yet to be resolved is the on bound fuel supply before fuel cells can be practically used for vehicles. Use of an on-board fuel reformer can mitigate the fuel supply issue. In particular, using a diesel engine as on-board fuel reformer, combined with a fuel cell, is a strong candidate...
