Design reuse

The decision to develop in-house or buy a tool or technique may arise as awareness of the opportunities in a business increases. Off-the-shelf products are more popular as the development of tools and techniques is very time consuming and labour intensive. A generally expressed desire is to use computerized techniques for easier documentation and design reuse. However, it should be noted that a paper-based...

In addition to characterizing designs, manufacturing processes must also be characterized and controlled to achieve overall business objectives. When a design reuses well-established processes (i.e., platforms), improved time-to-market and reduced development and manufacturing costs can be achieved. This section describes an approach to developing these process platforms.

The MICON system is intended to increase the productivily of the designer. While it may be conceptually obvious that the hierarchical organization of design knowledge would increase design reuse, and automation would reduce design time, we in ovide some anecdotal evidence to substantiate these claims. 

The use of excess reactants, diluents, or heat carriers in the reactor design has a significant effect on the flowsheet recycle structure. Sometimes the recycling of unwanted byproduct to the reactor can inhibit its formation at the source. If this can be achieved, it improves the overall use of raw materials and eliminates effluent disposal problems. Of course, the recycling does in itself reuse some of the other costs. The general tradeoffs are discussed in Chap. 8.

The dmm dryer is a continuously operated unit that uses rotating heated dmms for the evaporation contact area. This method of drying can be used with materials high in volatiles. In several designs, the volatiles can be withdrawn and coUected for reuse, as appropriate. 

Over the past decade, water pollution control has progressed from an art to a science. Increased emphasis has been placed on the removal of secondary pollutants, such as nutrients and refractory organics, and on water reuse for industrial and agricultural purposes. This in turn has generated both fundamental and appHed research, which has improved both the design and operation of wastewater treatment faciUties. 

The reaction vessel (nitrator) is constructed of cast iron, mild carbon steel, stainless steel, or glass-lined steel depending on the reaction environment. It is designed to maintain the required operating temperature with heat-removal capabiUty to cope with this strongly exothermic and potentially ha2ardous reaction. Secondary problems are the containment of nitric oxide fumes and disposal or reuse of the dilute spent acid. Examples of important intermediates resulting from nitration are summarized in Table 3. 

Solution We ll look at the input files for this exercise more closely than we often do. Here is the structure of the first set of jobs designed for examining the orbitals and planning the active space (note that we save the checkpoint file for later reuse) ... 

Filter elements may be of the 5-micron, woven mesh, micronic, porous metal, or magnetic type. The micronic and 5-micron elements have non-cleanable filter media and are disposed of when they are removed. Porous metal, woven mesh and magnetic filter elements are usually designed to be cleaned and reused.
