Prototype vessel

A prototype vessel was built and installed in the Big Lake field in mid-1977. With the above equations, this vessel has a design water capacity of 48,000 B/D (7631 m3/d). This rate is 150% of the desired throughput of 32,000 B/D (5088 m3/d). Initial water throughput was approximately 25,000 B/D (3975 m3/d). Figs. 3 and 4 display the results of several tests run at that time to determine effectiveness of this design. 

Current Development. Following success of the prototype IPU a second more comprehensive facility was commissioned. This is capable of up to four pumps of mixed peristalitic or diaphragm types, each linked to specific feed vessels on individual balances. The whole is interfaced to an IBM AT computer (see Figure 7) which in addition to Intelligent liquid additions, has the capacity to absorb modules from the work on temperature control and stirring in a full multi-tasking computer-assisted system, as mentioned above. 

A prototype of a microwave reaction vessel that takes advantage of bottom filtration techniques was presented by Erdelyi and Gogoll in a more recent publication. Therein, the authors described the use of a modified reaction vessel (Fig. 7.2) for the Emrys instruments (see Section 3.5.1) with a polypropylene frit, suitable for the filtration /cleavage steps in their microwave-mediated solid-phase Sonogashira coupling (see Scheme 7.19) [21]. 

A prototype system (100 kg waste per hour) which utilizes a nonrefractory metal vessel is under construction and was scheduled to begin operating in late 1983 (10). The unit is designed for transport to field sites for temporary waste destruction such as in cleanup of a hazardous waste site or continuous waste destruction at a waste generator s plant site.

As a result, if we consider scale-up from a 20-gallon to a 2,500-gallon agitated vessel, the scale ratio is equal to 5, and the impeller speed of the prototype will be... 

It is decided to model a full-scale prototype, unbaffled, stirred vessel with a one-tenth scale model. The liquid in the prototype has a kinematic viscosity, v. of 10 7 m2 s As we have seen above, power number is a function of both Reynolds number and Froude number for unbaffled vessels. To ensure power number similarity, we need to ensure both Reynolds number and Froude number are similar from prototype to model. 

The safety of pressure vessels is a concern, particularly in inhabited areas. Development and testing of prototype Hydrogen storage tanks should be connected with a study in depth of defectoscopy and microstructural characteristics of the involved constitutive materials, in order to understand more deeply their behaviour and assess their suitability.
