It is important to conceptualize plant layout in terms of both ideal location and optimal geographical positioning of equipment components For any chemical process facility, the cost of improper or sub-obtimal plant layout can be enormous. Designers are generally well…
Guidelines are presented to better understand the temperature profiles of high-velocity gases In high-velocity gas flows, such as those that may occur within the discharge piping of a pressure-relief or depressurization valve, the temperature experienced at the wall of the…
A wide range of factors must be taken into account before selecting the most appropriate reforming technology From the agrochemicals sector to steel production, from petroleum refineries to chemicals production — many sectors of the chemical process industries (CPI) would…
The physical characteristics of dispersed particles have a large impact on overall rheological properties Many important products of the chemical process industries (CPI) exist as suspensions or dispersions of particles in liquid media. Examples range from adhesives, ceramics, paints and…
The substance known colloquially as table sugar is actually sucrose, a disaccharide composed of fructose and glucose. Sucrose is a major agriculturally derived product with an established industry for its extraction, processing and supply. It is mainly employed as a…
Best-efficiency point (BEP), the flowrate at which a pump operates at its highest or optimum efficiency for a specific impeller diameter, is a key consideration when assessing pump performance. While most pumps do not consistently operate at their exact BEP,…
A small-diameter, submersible pressure transmitter The Sitrans LH100 series pressure transmitter converts level-proportional hydrostatic pressure into a standardized 4–20-mA signal. Mostly used for measurement applications in the drinking water and wastewater industries, the Sitrans LH100 offers 0.3% accuracy and is…
