Due to process variabilities and operational modifications, operating parameters of Heat Exchanger Network (HEN) may alter its output temperatures.
Operational modifications can be effective and usually incur little capital expenditure, but equipment changes may also be needed to achieve retrofit objectives.
This category includes excavating the lake outlet to produce a change in the stage discharge relation, while non-structural actions are concerned with functional or operational modifications of the system.
As part of the C111 spreader canal project, structural and operational modifications involving incremental raises in canal stage are planned along one of the major canals (i.e., C111) separating Everglades National Park and agricultural production areas to the east of the park.
Our results demonstrated that a combination of practical operational modifications (air-conditioner cycling, doing laundry later in the evening) and commercially-available technology (exterior shading, modest PV array, energy-efficient lighting) was able to dramatically reduce (in some cases to zero) the peak electrical demand from the grid on the hottest days of the year.
For instance, [42] does not directly address deadline and cost aspects, but the solution proposed could be used to cover them with slight operational modifications.
It may be noted that HEC-5 simulation model has been pointed out as being a well documented model and being used in a relatively large number of studies, including studies of storage reallocations and other operational modifications at existing reservoirs as well as feasibility studies for proposed new projects and for real-time operation [USACE Hydrologic Engineering Center (1991)].
Nonetheless, the impact of such operational modifications has not been directly addressed in this study and requires further investigation.
Suspecting that such a base (e.g., KOH, from the KH used to generate nitronate 9) may have been the cause of the lowered yields on larger scale, we instituted several operational modifications to improve the robustness of the oxidative desymmetrization reaction.
In order to strengthen operational stability, surface modification with (3-aminopropyl) triethoxysilane (APTES) and crosslinking with glutaraldehyde were performed; the operational stability of ADA immobilized on TiO2 APTES microparticles featuring various pore sizes was considerably higher than that of ADA immobilized on blank TiO2.
There is an extensive literature reporting physical, chemical, thermal, mechanical and operational data for modification of the chemical composition of polymer membranes by several groups.
