Although there has been big surge in biodiesel production recently, such fuels are not without problems of their own, such as low mileage, poor performance at lower temperatures, and adverse effects on engine components. Also, the production process for making biodiesel — the methyl esterification of fatty acids derived from vegetable oils (such as palm and rapeseed)...

    The dramatic jump in petroleum and natural gas prices over the recent years has created much impetus to reduce operating costs at chemical process plants. In processes that use either oil or gas for feedstock, such reduction can come either from improved energy-usage methods or from yield improvements. In either case, the plant's steam resource is often a primary provider of heat or...

    Energy consciousness and environmental awareness have transformed condensate from an inexpensive byproduct of steam distribution to a valuable resource that can substantially reduce operating costs. For process systems that use steam as the heat transfer media, improved condensate management can enhance the overall system performance and longevity. Condensate is a ready-made supply of...

    The process industries are extensive users of energy. But it is now clearly established that a large amount of this energy is wasted, essentially in the form of heat rejected to the environment through gaseous or liquid effluents. The temperature level of this heat makes it of no use by the process; and at the same time, in many cases, it cannot be economically upgraded. Examples of...

    Provided that they are updated when appropriate to keep them relevant, time-tested heuristics rules based upon experience, also referred to as rules of thumb, can be useful for the design, specifying and operation of several kinds of equipment used in process plants. The first and foremost heuristic rule is that the engineer should not shy away from using heuristics - and the second rule is...

The company also started to design a 500-1,000-m.t./yr plant for making SOG Si, and plans to start operations by March 2008. Up to now, JFE Steel used directional-solidification (DS), which aligns the Si...
