Plant environment

Preliminary in-field applications have also confirmed the successful long-term performance of the AEBIL instrumentation in power plant environment. 

The OSHA limits, regulations, and recommendations apply to in-plant air quaUty. Improperly filtered exhaust air may cause a plant to be in violation of the EPA standard, therefore these data should not be confused with the EPA limit for airborne lead, 1.5 fig lead/m, measured over a calendar quarter, which pertains to the exterior plant environment and emissions. The installation and proper maintenance of exhaust filtration systems enables most plants to comply with the EPA limits for airborne lead (see Lead compounds, industrial toxicology). 

When embodied in a modern integrated plant environment, dynamie plant health assessment, proeess modeling and proeess integration provide the means to augment plant reliability, availability and safety with maximum eapaeity and flexibility. 

The strength and ductility of brasses are well maintained over a range of 300° to -180°C, and castings are easy to make as well as to machine. Brass behaves similarly to copper in chemical plant environments, with somewhat greater rates of attack.

The SLIM technique is a highly flexible method that allows considerable freedom in performing what-if analyses. In common with most human reliability quantification techniques, it requires defensible data, preferably from a plant environment, to be effective. In the absence of such data, the calibration values have to be generated by expert judgments made by experienced plant personnel. 

The purpose of this chapter is to set out in concrete terms the ways in which the techniques described in the previous sections can be implemented in the chemical process plant environment. The integration of error and process safety management systems is also described.

In acid solutions, the behaviour of titanium/dissimilar-metal couples may differ from that just described, and on occasion titanium may be anodic to stainless steel and even to aluminiumIn chemical-plant environments, therefore, it is usual to take the precaution of insulating titanium from adjacent components constructed from other metals. 

AS of this writing, 100% inspection by NAA of small arms primers in an actual production loading plant has not been implemented, nor is it contemplated in the near future. Technical problems exist related to coupling the present state-of-the-art nuclear components with the high production rates for the primers, namely, tens of units per sec per automatic loading line. The high intensity of the neutron source and the complexity of the detection system required detracts from the utility of the method in a plant environment where simplicity and safety of operation are of paramount importance. Nevertheless, the technical feasibility of the method has been demonstrated by the AMMRC study and future developments in nuclear activation hardware may ultimately make this non-destructive inspection for production primers more viable...

Many analytical techniques are in use for the qualitative and quantitative evaluation of monomers and oligomers extracted from PA6 (GC, differential refrac-tometry, IR, PC, SEC, HPLC, RPLC, etc.). FTIR has been used for quantitative analysis of caprolactam oligomer content (extract %) in polyamide-6 [113], The method, which involves a 3h extraction in boiling methanol, is suitable for process control and plant environment. Kolnaar [114] has used FTIR characterisation of fractional extracts with pentane, hexane, and heptane of HDPE for blow moulding applications. Vinyl acetate in packaging film has similarly been determined by quantitative FUR. 

In the field of in-process analysis, analytical NMR applications also constitute a growth area - and also in relation to additives. This stems from the fact that the method makes it possible to use chemical analytical data in polymer quality control. Robust tools for hostile chemical plant environments are now available. The field of process analytical chemistry has been pushed to the forefront of the partnership between industry and academia.
