The objectives of the Study Design Update (SDU) were to identify the technical issues facing a potential commercial-size EDS plant design; to provide a reliable basis for estimating the cost of EDS products; and to furnish research guidance to the EDS Project. The SDU consists of two distinct studies in which different processing schemes are used to produce the hydrogen and fuel gas required by the plant. These studies are referred to as the Base Case and the Market Flexibility Sensitivity Case. In the Base Case, hydrogen is generated by steam reforming of the light hydrocarbon gases produced in the plant. Fuel gas is generated by feeding the bottoms stream from the liquefaction section vacuum pipestill to a FLEXICOKING unit. In the FLEXICOKING unit reactor, the bottoms stream is converted to coke; additional liquid product is also recovered. The coke is converted to low-Btu fuel gas in the FLEXICOKING unit gasifier. In the Market Flexibility Sensitivity (MFS) Case, the bottoms stream from the vacuum pipestill is split, and about half is sent to the FLEXICOKING unit for recovery of additional liquid product and production of fuel gas. The remainder of the bottoms stream is converted to hydrogen in a Partial Oxidation Unit. Hence the MFS Case does not consume light hydrocarbon gases produced and they are available for sale. The study of these two cases has demonstrated the importance of bottoms process selection to the economics and thermal efficiency of an EDS plant. Volume 1 - Main Report has been developed to be a stand-alone document. Both the Base Case and Market Flexibility Sensitivity (MFS) Case are covered. This volume includes an overview and detailed case summaries. It also covers economics, product recovery factors, material and energy balances, cost estimates and enviromental considerations.
