The Safety Instrumented Systems are used to monitor the condition of values and parameters of a plant within the operational limits and, when risk conditions occur, they must trigger alarms and place the plant in a safe condition or even at the shutdown condition.
2017-11-3 · Author reconsidered about calculation method of flash fire, because representative calculation methods are that all people will die in flammable gas dispersion area or people are received maximum radiation while flame burning. These methods are possible to overestimate consequence. Therefore, author calculates flash fire as below.
2010-4-14 · The accidents occurred between 1995 and 2006. Eleven of the injured employees were male, and nine were female. Costs of the workplace accidents to the employers The case studies show that a wide range of negative costs and effects resulted from the accidents. In terms of financial costs to employers, the amounts varied greatly
Journal of Engineering for Gas Turbines and Power; from the realistic analysis without taking into account uncertainties in the direction of their reasonably conservative calculation.

2010-1-27 · SIL stands for Safety Integrity Level. A SIL is a measure of safety system performance, in terms of probability of failure on demand (PFD). This convention was chosen based on the numbers: it is easier to express the probability of failure rather than that of proper performance (e.g., 1 in 100,000 vs. 99,999 in 100,000).
The landslide disaster tends to cause safe hidden trouble to the normal operation of the pipeline and pipeline is likely to take place accident and get failed under the action of a landslide. According to the theory of winkler, in the condition of pipeline landslide, the mechanical model is established and calculated the stress distribution under different landslide scale.
A calculation model of the corrosion rate and the cumulative corrosion depth were given. • The dynamic time-dependent probability of corrosion states was predicted by a Markov chain. • The prediction method can help to foreshow corrosion rupture accidents in chloride process.
2018-6-9 · on core support structure hardly occur, nor formation of inflammable gas mixtures in the containment either. Therefore air ingress accidents are not so serious in the case of fairly large HTGR's, if AHR goes orderly into operation. However, it must be presumed with a certain probability (which is estimated to be 2.5

2007-11-14 · period) wind probability that occurs in hurricane hazard areas. Thus, the return period of the design wind speeds along the hurricane-prone coast varies from roughly a 70- to 100-year return period on the wind map in the 1998 edition of ASCE 7 (i.e., not a traditional 50-year return period wind speed used for the remainder of the United States).

Risk-based inspection (RBI) has been applied to good effect in relation to pieces of equipment and pipelines in the petrochemical industry worldwide, but to the best of our knowledge application of RBI to power station boilers has not hitherto been reported.
2011-3-25 · The question is: what that probability means. If you say the probability is 1 in 1 million per year (for example) and there are 2 million devices then you can expect 2 accidents per year. The difficulty arises from working out the probability in the first case. If there are 2 million units and 2 accidents per year then the calculation is easy.
2011-4-7 · biomass boiler, and presented carbon emission numbers for both. The relevant sections of the permit are shown below.1 They reveal that the biomass boiler would emit 6 times more carbon (at 3,120 lb/MWh) than the adjacent natural gas turbine (at 510 lb/MWh). The Domtar plant was required to show its greenhouse gas emissions from biomass by EPA
