Currently there are significant amounts of natural gas that cannot be produced and treated to meet pipeline specifications, because that would not be economically viable. This work investigates a bench scale multistage fluidized bed (MSFB) with shallow beds for sour gas removal from natural gas using a commercially available supported amine sorbent. A MSFB is regarded as a promising adsorber ty...

An “across-the-fence” steam-methane reforming (SMR) hydrogen plant integrated with gas-turbine technology was started up within the past three years at the Premcor refinery in Port Arthur, Texas. This plant, owned and operated by Air Products and Chemicals, Inc., is one of only a handful of SMRs containing an integrated gas turbine. The facility design typifies a growing trend among refiners to...

A small-size gasification unit is improved through process optimization to simulate industrial United Gas Improvement Company gasification. It finds that the reaction temperature has important impacts on semicoke catalyzed methane gas mixture. The addition of water vapor can enhance the catalytic activity of reforming, which is due to the fact that addition of water vapor not only removes carbo...

The use of a plasma reformer for the generation of hydrogen rich gas from diesel fuel has been investigated. A system that is normally used for investigating natural gas reforming has been modified in order to investigate the reforming of heavy liquid fuels. The composition of the reformate has been investigated as a function of the composition of the reagents. The use of a one-step reformer/wa...

Decreasing supplies of high quality crude oil and increasing demand for high quality distillates have motivated the interest in converting natural gas to liquid fuels, especially with the present boom in natural gas proven reserves. Nevertheless, one major issue is the curtailment of costs incurred in producing synthesis gas from natural gas, which account for approximately 60% of the costs use...

This paper documents the application of exhaust gas fuel reforming of two alternative fuels, biodiesel and bioethanol, in internal combustion engines. The exhaust gas fuel reforming process is a method of on-board production of hydrogen-rich gas by catalytic reaction of fuel and engine exhaust gas. The benefits of exhaust gas fuel reforming have been demonstrated by adding simulated reformed ga...

in an attempt ot develop a one step process for the removal of h2s from sour gas, the engineering consideration were dealt with in two steps. in the first step it was attempted to derive the data required for establishing the design criteria for a pilot plant, by experimenting with a small bench scale.

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

Abstract: Hydrogen production via Sorption-Enhanced Chemical-Looping reforming combines hydrocarbons reforming (in this case methane reforming), by chemical-looping auto-thermal reforming, with water-gas shift and carbonation reactions. Both H2 production rate and concentration depend on the chemical equilibrium that is established in the fuel reactor and that is influenced by several parameter...
