During process operations, elevated pressure inside of isolated zones within a process or system can be rapidly reduced by the release of gas and vapor to a dedicated blowdown network. Analysis can be carried out to determine whether a given pressure-relief device will provide sufficient protection from potential vessel rupture for an unwetted-wall vessel or a vessel containing a high-boiling-point liquid...

Increasing production of crude oil from shale deposits in the U.S. and oil sands in Canada offers North American petroleum refiners opportunities to access cost-advantaged feedstock. However, shifting product demand and hurdles in transportation logistics, along with technical issues associated with the properties of the crude from those areas, present challenges as refiners optimize their product mix...

Lessons learned Your Editor’s Page in today’s Chemical Engineering [March 2013, p.5] intrigued me because I too served as a TA in a physical chemistry lab but long before 1980 and we did not have the luxury of a Fourier-transform infrared spectrometer. But you certainly have the experience to comment on the following: The earth, according to Weil’s law at an average temperature of...

Minimizing process variability is an important component of a plant’s profitability. The performance of control valves within process control loops has a significant impact on maintaining consistent processes. This refresher outlines some of the important aspects of control-valve performance, including parameters of both the static response and the dynamic response. Static response A valve’s...

Inline viscosity measurements can give continuous, realtime readings of a fluid’s viscosity during processing and consequently, can provide a means to automate the viscosity control of process fluids. While it is difficult to control all factors in the process that can affect a fluid’s viscosity (such as temperature, air bubbles, shear history, turbulence and so on), if these factors are kept...

Some injuries are permanent; some injuries are total. People who work for, or near, small companies need to be protected just as much as those associated with large companies. Small companies, however, usually cannot afford to employ full-time, certified, degreed, safety professionals. From my own career experiences, it seems as though a company with less than 50 employees cannot afford to employ an expert...

Sodium hypochlorite (NaClO) is the active constituent in chlorine bleach, a strong oxidizer and bleaching agent. Increases in household bleach demand are driven mostly by population growth. In turn, population growth and its corresponding increases in water consumption — coupled with limited fresh water resources — makes water treatment the largest application for bleach, as well as the...
