System specification

The approximation to the closed integral improves as the number of iterations increases up to a point. The actual values in Table 1-1 may be system specific, that is, different hardware and software combinations may give slightly different results because of different ways of storing numbers. One is tempted to think of approximations as getting better without limit, the sum approaching the integral...

Antimicrobial efficacy is also affected by demand in the cooling water system, specifically demand exerted by ammonia. Chlorine reacts with ammonia to form chloramines, which are not as efficacious as hypochlorous acid or the hypochlorite ion in microbiological control. Bromine reacts with ammonia to form bromamines. Unlike chloramines, bromamines are unstable and reform hypobromous acid.

The constant may depend on process variables such as temperature, rate of agitation or circulation, presence of impurities, and other variables. If sufficient data are available, such quantities may be separated from the constant by adding more terms ia a power-law correlation. The term is specific to the Operating equipment and generally is not transferrable from one equipment scale to another. The system-specific constants i and j are obtainable from experimental data and may be used ia scaleup, although j may vary considerably with mixing conditions. Illustration of the use of data from a commercial crystallizer to obtain the kinetic parameters i, andy is available (61). 

Because of the different vulcanization chemistry involved in each commercial ACM, a vulcanization system specific to the cure site present has to be adopted. Many cure systems for labile chlorine containing ACM have been proposed (45). Among these the alkali metal carboxylate—sulfur cure system, or soap—sulfur as it is called in the United States, became the mainstay of acryflc elastomer technology in the early 1960s (46), and continues to be widely used. 

By attempting to maintain process conditions at or near their design values, the process controls so attempt to prevent abnormal conditions from developing within the process. Although process controls can be viewed as a protective layer, this is really a by-product and not the primaiy func tion. Where the objective of a function is specifically to reduce risk, the implementation is normally not within the process controls. Instead, the implementation is within a separate system specifically provided to reduce risk. This system is generally referred to as the safety interlock system.

This section provides a detailed example of flare system specification. This is an example of a formal design document that would be provided by the plant designer to a flare system vendor. The reader should consider this section as an example of the types of information and level of detail needed in specifying the system, however the format and organization might certainly be changed to suit the particular needs of the plant operations. 

RISKMAN embodies PLG s scenario-based, engineering-approach displays and calculates event sequence diagrams, fault trees, and event trees. It allows for system-specific data updates and accoums for dependencies between systems. 

Certain operations require that the workspace be at a lower pressure than surrounding workspaces, e.g., radioisotope laboratories. In these cases, the exhaust flow rate should exceed the supply flow rate, but this excess should he within 10%. The additional resistance resulting from this imbalance should be considered in the design of the exhaust system, specifically in the selection of exhaust fans.

Under certain situations, for specific equipment configurations, it may be possible to safely operate above the NFPA limit of 60% of the LFL. If this method of operation is to be considered, system-specific test data should be generated which demonstrates dial the combusdble concentradon can be controlled in a safe manner, and only then in consultadon with appropriate company and (where required) regulatory authorities. 

On the part of the contractor team, two root causes were identified, root cause 1 being insufficient training of the contractor team leader. He was uncertain of permit systems, specifically whether they should report in at the end of shift, and, if so, who should do it. The second root cause relates to the procedure used at the end of the shift for supervisors to sign back permits. Although according to procedure all workers should hand back permits to supervisors in person, in practice this did not occur. If no one is present, or they are busy, it had become common practice to either leave the permits on the supervisor s desk, or to sign them back in the morning.
