Trap Problems

Some of the more common problems associated with stea traps include

The Group 6 compounds glucose and glycine were not tested at the small-scale level because previous work suggested that they would not be soluble in supercritical fluid CO2. Additionally, chloroform was not tested at this level because it is undoubtedly extractable but would pose significant trapping problems because of its relatively high vapor pressure. 

This power-law dependence on time is the same as in Eq. (3.249), where Z should be set to 1 for a stable complex (t6XC = oo). The peculiarity of the dense solution is the concentration-dependent multiplier (1 I cKeq) 1 arising in (3.712). However, this concentration dependence is inherent in IET only, as it differs in other theories compared below. Using more adequate methods for studying the target [180,241,242,253,254] and trap problems [180,242,252], it was proved that... 

However, MPK1 as well as MPK2 describe only the target problem, while MPK3 is able to treat the trap problem as well (Table IX). At equal lifetimes MPK3 exactly reproduces MET in both these limits [126,252]. 

Radiative Trapping. The radiative trapping problem is illustrated in Figure 6. 

The release problem can be seen as a study of the kinetic reaction A+B —> B where the A particles are mobile, the B particles are static, and the scheme describes the well-known trapping problem [88]. For the case of a Euclidean matrix the entire boundary (i.e., the periphery) is made of the trap sites, while for the present case of a fractal matrix only the portions of the boundary that are part of the fractal cluster constitute the trap sites, Figure 4.11. The difference between the release problem and the general trapping problem is that in release, the traps are not randomly distributed inside the medium but are located only at the medium boundaries. This difference has an important impact in real problems for two reasons ... 

The problem is inherently a finite-size problem. Results that otherwise would be considered as finite-size effects and should be neglected are in this case essential. At the limit of infinite volume there will be no release at all. Bunde et al. [84] found a power law also for the case of trapping in a model with a trap in the middle of the system, i.e., a classical trapping problem. In such a case, which is different from the model examined here, it is meaningful to talk about finite-size effects. In contrast, release from the surface of an infinite medium is impossible.

K more recent and exact solution to the one-dimensional, nearest neighbor transport and trapping problem has been given by Movaghar. [20] Its predictions for M are indistinguishable from the series solution. [21] In Figure 1 we present the dependence of M,... 

Cycling (30 s - several minutes duration) instrument fault/condensate in instrument sensing lines/[foaming] /liquid maldistribution/steam trap problems (see Section 5.1)/unsteady vacuum (see Section 2.2). 

Moulders that experience air trapping problems will know how difficult it is to cure this problem when in production. It is a fault best avoided at the design stage. 

Poor maintenance practices or the lack of a regular inspection program may be the primary source of steam trap problems. It is important for steam traps to be routinely Inspected and repaired to assure proper operation.
