Recommended Fluid Velocities in Pipelines - Chemical Engineering
Dec 1, 2018 · 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.
Ethylene Glycol Production - Chemical Engineering | Page 1
Oct 1, 2015 · Ethylene Glycol Production. October 1, 2015 | By Chemical Engineering. Monoethylene glycol (MEG), also known as ethylene glycol (EG) or simply glycol, is a diol mostly used for the production of polyester fibers and polyethylene terephthalate (PET) resins. It is also used in antifreeze applications and in pharmaceuticals and cosmetics.
Determining Packing Height With Accuracy - Chemical Engineering
Oct 1, 2011 · Determining Packing Height With Accuracy. Equilibrium stage simulations are the nearly universal process design tool for mass transfer columns that contact vapor and liquid in countercurrent flow. Whether the service is absorption, stripping, distillation, fractionation, quench or evaporation, equilibrium stage models make mass and heat ...
Getting the Most Out of Your Rupture Disc - Chemical Engineering
Mar 1, 2009 · Ways to avoid pressure spike problems include: avoiding the use of rupture discs on long, liquid-filled lines, eliminating fast-closing-and-opening process valves, and using pressure accumulators to absorb the unavoidable pressure spikes. FIGURE 1. This viscous-tee holder design continually wipes. the disc surface, preventing product buildup.
Filtration Centrifuges: An Overview - Chemical Engineering
Dec 1, 2010 · (Page 1) To solve the task of solid-liquid separation in the chemical process industries (CPI), a wide variety of methods are invariably used. Many of these methods are not mutually exclusive and include a selection of technologies that can be expediently combined to provide an efficient operating system. A good understanding of the centrifuge options available and details of the individual ...
Flare Selection for the Chemical Process Industries
Apr 1, 2018 · Flare design. A flare is a device used to safely dispose of unwanted or excess gases and liquids from normal, unplanned or upset conditions during process operations in CPI sites. Flaring is done by burning off the gas or liquid into the atmosphere. The gases or liquids to be combusted are usually rich in heat content, enabling them to self ...
Commercial Progress on Turquoise Hydrogen - Chemical …
The cost of turquoise H 2 produced by methane pyrolysis is currently $1.80-4.00/kg H 2 without any carbon sales or revenue from carbon offsets. This is not yet cost-competitive against grey hydrogen produced by SMR ($0.90 to 3.00/kg), but may compete with blue hydrogen ($1.40 to …
Gas Sparging - Chemical Engineering | Page 1
Gas Sparging. September 1, 2012 | By Chemical Engineering. Sparging refers to the process of injecting a gas through a diffuser into a liquid phase. It is used in both physical and chemical process applications. In physical process applications, the gas is used to either dissolve gas into liquid (such as aeration….
