And while a recent wave of successful demonstrations has begun to emerge in the CPI (for more, see CE, Nov. 2009, p. 17–23), a number of hurdles stand in the way of a completely wireless Utopia. In most cases, the totally reliable, uncompromised availability of a production plant remains a paramount objective, and it will therefore likely take some more time before radio transmissions of critical signals in control loops take root.... http://www.che.com/environmental_health_and_safety/plant_and_personnel_safety/hazardous_substances/5639.html Sat, 1 May 2010 0:00:00 EDT Topics of other recently published chemical engineering books include: petroleum microbiology, scaling analysis, polymer melt processing, reactive distillation design, diffusion and nanotechnology... http://www.che.com/environmental_health_and_safety/plant_and_personnel_safety/hazardous_substances/5010.html Tue, 1 Sep 2009 0:00:00 EDT Most common acids can be stored in horizontal or vertical ASME-type tanks, as shown in the figures to the right, or vertical API-type tanks.
