Most conditions and features of the conceptual process are chosen to assure high throughputs (small equipment) and hence relatively low capital and fixed costs. These include the choice of flow regimes, heat carriers (density and heat capacity) and the solids-to-gas weight ratios. Attendant features of the process, such as baffle design and gas routing, are chosen to achieve operability and optimum operation. 

CACHE (Computer Aids for Chanical Engineering CACHE Corporation, 2016) Process Design Case Studies represents an outstanding resource of many case studies. These are covered in 11 different volumes that span Separation System for Recovery of Ethylene and Light Products from Naphtha Pyrolysis Gas Steam in Volume 1, all the way to Conceptual Design of an Aromatics Plant from Shale Gas in Volume 2. 

For over four decades, many process engineers have witnessed and participated in many major crude oil and gas production facility conceptual and detail engineering designs. Some of these designs were the first of their type. However, our main core of surface facility design...

Initial experiments were performed to verify and demonstrate the feasibility of the electrolytic reduction method with uranium, followed by experiments with a mixture of uranium and plutonium. Experiments were conducted batchwise in a small electrolytic cell. Basic parameters, such as concentration of solutes and type of holding agents (in the aqueous phase) for removal of any nitrite which would reoxidize the reduced heavy metal, electrode material and geometry, off-gas composition and type of diaphragm, were also determined. These data were valuable in the conceptual design of the first continuously operating column for the electrolytic reduction process.

In the conceptual design, the nuclear plant is a type of SFR, mixed oxide fuel, sodium cooled with power output of 240 MWt for producing 200 000 Nm /h. The schematic diagram of nuclear-heated recirculation-type membrane reformer is shown in Figure 15. The hydrogen production cost of this process is assessed to be competitive with those of the conventional, natural gas burning, steam methane reformer plants. 

The probabilistic safety assessment (PSA) for the steam reforming process was carried out to investigate the cause of an accident on combustible gas leak and a conceptual design on a countermeasure against explosion was carried out aiming at reducing the probability ofthe combustible gas leak less than 10-6/year. The rupture of combustible gas pipes is considered as the cause of the leakage. 

In the early stages of conceptual design, simple design heuristics permit to exclude inadequate alternatives without detailed knowledge about the process. For instance, [530, 531] propose some rules for the design of separation systems for liquid and gas/vapour mixtures.
