Developments in Processing Technology

Developments in blow moulding include process variants such as suction blow moulding. EMS-Grivory has developed the Ecosys process for extending three-layer, semi-flexible water pipes for engine cooling systems. They have a PA 12 resin layer and an inner layer made of a polyolefin compound, bonded by a tie layer.

The reactor is the heart of most processes, developments in process technology often centre around improvements in the design and operation of the reactor. This is often the basis of new and improved processes. Subsequent stages in the chemical process are usually concerned with the separation of various chemicals from the desired product, followed by the final purification stages. 

The ethylene-based, balanced vinyl chloride process, which accounts for nearly all capacity worldwide, has been practiced by a variety of vinyl chloride producers since the mid-1950s. The technology is mature, so that the probabiUty of significant changes is low. New developments in production technology will likely be based on incremental improvements in raw material and energy efficiency, environmental impact, safety, and process reUabiUty. 

Increasing price of crude oil has built up pressure on tire and automobile industry to develop low rolling-resistant tire with better traction. Combination of carbon and silica with coupling agent (dual filler technology) shows low RR with better traction and skid resistance in tire tread compound. Carbon black developed by plasma process and nanostructure black are other new significant developments in filler technology. 

A major development in pharmaceutical technology has been the application of instrumentation techniques to tablet presses. The ability to monitor the forces that develop during the compaction, ejection, and detachment of tablets has brought about new insights into the physics of compaction, facilitated formulation development, and provided a means for the in-process control of tablet weight in manufacturing [62,63], In... 

Recent developments in microsystems technology have led to the widespread application of microfabrication techniques for the production of sensor platforms. These techniques have had a major impact on the development of so-called Lab-on-a-Chip devices. The major application areas for theses devices are biomedical diagnostics, industrial process monitoring, environmental monitoring, drug discovery, and defence. In the context of biomedical diagnostic applications, for example, such devices are intended to provide quantitative chemical or biochemical information on samples such as blood, sweat and saliva while using minimal sample volume. 

This paper discusses the latest advances in manufacturing Community Antenna Television (CATV) cables via the gas injection process. Developments in polymer technology are discussed which have led to the production, by gas injection, of highly expanded, ultra low dielectric loss PE cable insulation for CATV and data transmission 3 refs. 

However, systems with localized atoms represent only a first challenge. The next challenge is monitoring atomic motions in systems that vary in time. Following atomic motions during a chemical process has always been a dream of chemists. Unfortunately, these motions evolve from nanosecond to femtosecond time scales, and this problem could not have been overcome until ultrafast detection techniques were invented. Spectacular developments in laser technology, and recent progress in constmction of ultrafast X-ray sources, have proved to be decisive. Two main techniques are actually available to visualize atomic motions in condensed media. 

A more recent development in ethylbenzene technology is the Mobil-Badger process,161,314-316 which employs a solid acid catalyst in the heterogeneous vapor-phase reaction (400-45O C, 15-30 atm). A modified H-ZSM-5 catalyst that is regenerable greatly eliminates the common problems associated with... 

The principal thrust ol Japan s joint research programs is the development of process technologies to reduce conversion costs and development of high value-added products. Energy cost reduction is a prime concern. Opportunities exist in low energy consuming polymerization and spinning... 

To appreciate the rapid development of process technology, the progression of the IC industry must be considered first. (For summaries of the historical development of this field, see references 1 and 2.) A central theme in the IC industry is the simultaneous fabrication of hundreds of monolithic ICs (or chips) on a wafer (or slice) of silicon (or other material such as gallium arsenide), which is typically 100-150 mm in diameter and 0.75 mm thick. In silicon technology, chip areas generally range from a few square millimeters to over 100 mm2. A large number (often more than 100) of individual process steps, which are precisely controlled and carefully sequenced, are required for the fabrication.
