In this study detailed fault trees with probability and failure rate calculations were generated for the events (1) Fatality due to Explosion, Fire, Toxic Release or Asphyxiation at the Process Development Unit (PDU) Coal Gasification Process and (2) Loss of Availability of the PDU. The fault trees for the PDU were synthesized by Design Sciences, Inc., and then subjected to multiple reviews by Combustion Engineering. The steps involved in hazard identification and evaluation, fault tree generation, probability assessment, and design alteration are presented in the main body of this report. The fault trees, cut sets, failure rate data and unavailability calculations are included as attachments to this report. Although both safety and reliability trees have been constructed for the PDU, the verification and analysis of these trees were not completed as a result of the curtailment of the demonstration plant project. Certain items not completed for the PDU risk and reliability assessment are listed.

Six major process simulators are widely used in the chemical process industries today. These are ASPEN PLUS, BATCH PLUS and HYSYS.Plant (Aspen Technology, Inc.), PRO/n (Simulation Sciences, Inc.), CHEMCAD (ChemStations, Inc.), and SUPERPRO DESIGNER (Intelligen, Inc.). In this book and the associated multimedia CD-ROM, coverage is provided of ASPEN PLUS and HYSYS.Plant, which are the two most widely used process simulators. It should be mentioned that once the principles of process simulation are understood, it is a relatively easy matter to switch from one simulator to another.
