摘要:

AbstractA computer‐based simulator was used for training operators prior to the start‐up of a new fertilizer complex which includes a 1,350‐MTPD ammonia plant, two 1,100‐MTPD urea plants, and a steam and power generation plant with two 18‐MW gas turbines. The simulator offered many benefits, which can be used for continued education of operators and engineerin

摘要:

AbstractThe Design Institute for Emergency Relief Systems (DIERS) and more recently the DIERS Users Group have been investigating various aspects of emergency relief for more than 12 years. The DIERS programs have given rise to an in‐depth understanding of the basic mechanism of how runaway thermal reactions are safely vented. In concert with the development of the understanding of the venting mechanism, DIERS also developed experimental procedures and computational techniques for estimating emergency vent size

摘要:

AbstractThis paper addresses the unusual combustion hazards of silane and its chlorides, comprising the homologous chlorosilane series SiHnCl4‐n. The literature on silane is briefly reviewed and new experimental data presented showing the effects of sudden releases into free air. New data are presented for ignition sensitivities and deflagration rates of chlorosilane mixtures with air. Specific hazardous reactions of this group of materials are described and contrasted with those of the analogous alkanes. Mechanisms for flame acceleration and transition to detonation are discusse

摘要:

AbstractIn 1986 one of Du Pont's plants experienced a damaging fire in and around a vaporizer containing a high‐temperature heat transfer medium (HTHTM). There were no injuries, but there was considerable property damage and lost production. A review of HTHTM history showed other plants and companies had experienced both damaging fires and incidents of severe damage to the vaporizer with no accompanying fire. This suggested a study in more depth than usually associated with one specific inciden

摘要:

AbstractThe du Pont Company has long acknowledged its responsibility for environmental and public safety. In 1938 an Executive Committee resolution cited environmental control as a subject of major concern, and in 1971 that committee called upon each department to determine that their products could be made, used, handled, and disposed of safely.

摘要:

AbstractThe ability to estimate the intensity of accidental dust explosions is an essential prerequisite of methodologies intended to provide design guidelines for the protection of equipment and buildings where combustible dusts are being handled. In general, the severity of an explosion depends on the type of dust involved, its physical properties (such as particle size and moisture content), the characteristics of the interested volume (size, shape, presence of vents, and blockages), the strength and type of the ignition source, and the conditions of the environment (air flow, turbulence).
