Within the German public funded project p.PRO.CHEM, a concept for a continuously operated modularly assembled flexible pilot plants for highly exothermic two-phase liquid-liquid or gas-liquid reactions will be developed and validated [48]. The plant features process intensifying microprocess technologies. A goal of the project is the demonstration of the technical and economic feasibility of the plant concept on pilot scale with selected model processes.

Application New generation Spherilene gas-phase technology with simplified process flow scheme, to produce the full range of linear-low-density polyethylene (LLDPE), medium-density polyethylene (MDPE) and high-density polyethylene (HOPE) The technology features process simplicity, best in class monomer efficiency as well as catalyst and process options and is able to meet all product portfolio requirements. 

The last step calls for the development of the HOL polymer/photoresist film stack in an aqueous basic solvent such as 0.26 N tetramethylammonium hydroxide. This will dissolve and wash away the exposed part of the resist, comprising the carboxylic acid moieties. The preferential diffusion of the HOL into the exposed area of the photoresist results in deprotection of the photoresist polymer at the edge of the unexposed features, leading to their dissolution. This is the basis of the CD reduction, improved process window, and exposure latitude, and smoother sidewall and line edge profile of photoresist features processed with HOL relative to the features processed without HOL. ...

Work domain analysis (WDA) comes from a suite of analytical methods, known collectively as cognitive work analysis (Vicente 1999). The basic premise of the approach is that work activity should be understood in terms of its constraints - that is, the limitations and demands that the work environment places on behaviour due to its physical, social and psychological characteristics. Work domain analysis is used to identify the structural and functional relationships present within a work setting. These are presented in a multi-level map of the work setting (Figure 5.4) that links its highest level features (purposes and priorities) to its lowest level features (processes, tasks and physical objects). 

Several types of automation and control systems have been used and all have performed successfully. Thus the WER-440 Is fully developed to be fitted with state-of-the-art Instrumentation, automation and control system technology covering several operating modes. This includes advanced control room layouts featuring process computers and colour CRT-dlsplays for monitoring and control duties.
