Modular design

The modular design concept allows quick adoption of the tubes to changing radiation specifications. 

Heat/Solvent Recovery. The primary appHcation of heat pipes in the chemical industry is for combustion air preheat on various types of process furnaces which simultaneously increases furnace efficiency and throughput and conserves fuel. Advantages include modular design, isothermal tube temperature eliminating cold corner corrosion, high thermal effectiveness, high reHabiHty and options for removable tubes, alternative materials and arrangements, and replacement or add-on sections for increased performance (see Furnaces, fuel-FIREd). 

Provision of a segregation between the adjacent feeders in a modular design. 

The modular design integrates, as far as possible, existing software from member states, to permit the free distribution of the package. Version 1.0 of PSAPACK was used in a IAEA international training course on PSA in safety decisions (1988). Since then, PSAPACK evolved in response to users requirements, and has been widely distributed. 

Fabrication of baghouses can be of modular design, factory-welded subassemblies, or structural design. The selection of the type of fabrication depends on size of unit, transportation requirements, site location, physical location of unit at plant (e.g., on roof), and materials of construction. 

These gas transfer membranes or membrane contactors employ microporous polypropylene hollow fiber membranes arranged in a modular design. Oxygenated water flows on the shell side of the hollow fibers, and a strip gas (such as nitrogen) or a vacuum is applied to the inside (lumenside), with the hollow fibers acting as a support medium for intimate contact between the water and gas phases. 

The most complex automated systems are used almost exclusively by centralized HTS operations in large pharmaceutical companies and are referred to as ultra HTS (uHTS) platforms. They typically consist of the same four functional instruments, but have the capacity to process several hundred plates per extended workday. They often incorporate a modular design philosophy with multiple duplicate instruments for enhanced capacity that offer some functional redundancy. The mechanism for moving plates from one instrument module to another is often, but not always, a continuous track-way that resembles an industrial assembly line rather than the robotic arm typically used in a workcell system [5-8],...

The modular design of the HyPM fuel cells allows scaling for higher power requirements using a variety of configurations, such as series and parallel systems. Potential applications for the technology include vehicle propulsion, auxiliary power units (APU), stationary applications including backup and standby power units, combined heat and power units and portable power applications for the construction industry and the military. 

The relative simplicity of the gasification system enables its operation to be within the technical expertise of most operators who are experienced with conventional boilers and furnaces, and results in favorable project economics. Its modular design allows a wide range of scale-up or scale-down possibilities, so the systems can vaiy in size from about one ton per hour of residue to 20 tons per hour or larger, with the size being limited only by biomass availability.

Advantages of RBCs include the ability to sustain shock loads because of high microorganism concentrations, ease of expansion because of modular design, and low power consumption, which may be particularly attractive for industrial application. Full-scale RBC installations in refineries have performances in removal of oxygen-demanding pollutants comparable to activated sludge systems [5]. 

Modular design. Synthetic molecules were constructed of multiple, closely related nonsymmetric repeat units that can be covalently attached from either end. This approach allows rational design of various congeners, controlling their physical properties, such as iron-binding capacities and partition coefficients (lipophilic/hydrophilic...
