Recommended Fluid Velocities in Pipelines - Chemical Engineering
WEBDec 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.
Solids Drying: Basics and Applications - Chemical Engineering
WEBApr 1, 2014 — 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 ...

Ethylene Production via Cracking of Ethane-Propane
WEBNov 1, 2015 — The process shown in Figure 1 is a steam-cracking process for ethylene production from an ethane-propane mixture. The process can be divided into three main parts: cracking and quenching; compression and drying; and separation. Figure 1. This process diagram shows an ethylene-production process via the cracking of an ethane-propane mixture.

Maintenance cost: 10% of installed cost per year. Motor efficiency: 65% (assumed) Option 2: 4 × 3 – 13 2,850 rpm. Installed cost of pump and motor: $40,000 for 2,850 rpm.
Piping for Process Plants Part 6: Testing and Verification
WEBJun 15, 2008 — The design temperature is from –29°C (–20°F) through 186°C (366°F) The initial service leak test is a process by which the test fluid is the fluid that is to be used in the intended piping system at operating pressure and temperature. It is accomplished by connecting to the fluid source with a valved connection and then gradually ...
Hopper Design Principles - Chemical Engineering | Page 1
WEBJan 1, 2016 — δ. φ. Jenike [1] found that the hopper angle required to allow flow along the walls depends on the friction between the powder and the walls, the friction between powder particles, and the geometry of the hopper.Design charts originally developed by Jenike [1] provide allowable hopper angles for mass flow, given values of the wall friction angle and the effective angle of internal friction ...
