Recommended Fluid Velocities in Pipelines - Chemical Engineering
2018年12月1日 · As presented below, the optimization of pipe diameters can be accomplished using equations that relate the recommended velocity of fluids and the cost of energy. To determine the recommended velocities and compare what was published 10 years ago [1] to 2017, Equation (1) is used (Table 1, top). It is presented in Ref. 2.
LS solution for combustion management. Since the system measures gas concentration in the radiant section of the fired heater, it improved the heater sa. ety and overall operational eficiency.In this application, the system is installed with two TDLS analyzers for measurement of O2, CO and CH4 concentration.
Solids Drying: Basics and Applications - Chemical Engineering
2014年4月1日 · Drying may be defined as the vaporization and removal of water or other liquids from a solution, suspension, or other solid-liquid mixture to form a dry solid. It is a complicated process that involves simultaneous heat and mass transfer, accompanied by physicochemical transformations. Drying occurs as a result of the vaporization of liquid by ...

Viscosity: The Basics - Chemical Engineering | Page 1
2009年8月1日 · To be brief, viscosity is resistance to flow. For handlers of all materials that flow, either while being processed or in an end-use, it is important to think about the materials’ flow characteristics. The bottom line is to come up with ways to measure viscosity so that you can quantify whether a material will flow the way it needs to.
