Site selection, criteria for

Well-site selection Criteria for assessing the feasibility of a deep-weU-injection site include (1) uniformity, (2) large injection formation). Adjustment of pH and buffering of the waste maybe necessary.

This has proved to be shortsighted, and selection criteria for new sites will almost certainly contain specific guidelines on such things as cap or cover design and type of waste form permitted to be buried. 

Sponsors and CROs are looking for study conduct providers that offer fewer-stop shopping, combined with highly effective patient recruitment and retention, and ease of entry and market penetration. As a result, the following are becoming increasingly important site selection criteria ... 

The practical consequences of this conclusion can be far reaching both in the recognition of the detail required in site investigation and in the formulation of possible new constraints for disposal site selection criteria in general. 

Note that the example SIL levels provided in this chapter are only examples. They are not to be assumed recommended levels of protection. The selection of an appropriate Safety Integrity Level (SIL) is site-specific and the analysis requires selecting criteria for tolerable risk, and evaluating process conditions, specific chemicals, equipment design-limits, control schemes, process conditions, and unique hazards. Experts in process engineering, instrumentation, operations, and process safety should imdertake SIL selection. 

On the other hand, in Europe, the site selection criteria usually consider the site-plant complex. Therefore, for example, if a plant with the usual safety systems could not be located on a specific site because accident doses exceeded the reference limits, it was possible to make the plant acceptable for the same site by the improvement of the systems for fuel integrity protection in case of accidents. 

The production of LFG and leachate at a landfill, must be minimized, monitored (unless CH4 production is desired) and controlled if environmental impacts are to be minimized. Some of the uncertainties in landfill operation include the selection criteria for containment or open site management consequences of co-disposal moisture input rates and gas recovery. ... 

Following a theoretical analysis of distributed small-plant manufacture, Benson and Ponton define assessment criteria for processes suitable for such processing [139]. Since micro reactors are one of the favorite and natural tools for distributed manufacture, this selection list also defines micro-reactor applications. In this context, the authors, probably in one of the first regular citations, emphasize that formulation processes, especially those with multiple ingredients, are particularly suited for distribution. The making of paint on-site is referred to as an already existing way to do so. It stands to reason to augment the scope from formulations to functional chemicals. 

We propose that a relatively small number of watershed sites be established for intensive monitoring. These sites should be selected based on the criteria for site selection discussed previously (see Section 2.1.3). In particular, these sites should be located in areas that ...

Liston (Ref. 27) provides useful checklists for equipment and building siting and layout for safety purposes, as well as other safety-related criteria for plant design. These checklists address economic considerations and facility geographical location, site selection, layout, and unit plot planning factors.

Selection of on-site analytical techniques involves evaluation of many factors including the specific objectives of this work. Numerous instrumental techniques, GC, GC-MS, GC-MS-TEA, HPLC, HPLC-MS-MS, IR, FTIR, Raman, GC-FTIR, NMR, IMS, HPLC-UV-IMS, TOF, IC, CE, etc., have been employed for their laboratory-based determination. Most, however, do not meet on-site analysis criteria, (i.e., are not transportable or truly field portable, are incapable of analyzing the entire suite of analytes, cannot detect multiple analytes compounded with environmental constituents, or have low selectivity and sensitivity). Therefore, there exists no single technique that can detect all the compounds and there are only a few techniques exist that can be fielded. The most favored, portable, hand-held instrumental technique is ion mobility spectrometry (IMS), but limitations in that only a small subset of compounds, the inherent difficulty with numerous false positives (e.g., diesel fumes, etc.), and the length of time it takes to clear the IMS back to background are just two of its many drawbacks. 

Essentially, any molecule could potentially be used as a probe molecule. However, practically, a useful probe molecule should meet certain minimum criteria. Such criteria for the selection of an ideal probe molecule were first developed by Paukshtis and Yurchenko [104]. These have been refined by several research groups and summarized by Knozinger and Huber [86]. The criteria are summarized in Table 4.3. Based on these criteria, small, weakly interacting probe molecules are recommended for zeolites particularly when you want to probe sites within the pore structure.
