Horizontal Knockout Drum

They have higher separation efficiency than a horizontal knockout drum. [Pg.2295]

Another equation for quick sizing of horizontal knockout drums/ catch tanks is presented by Tan Hydroca rhon Processing, October 1967, p. 149). He recommends the following equation for calculating the drum diameter ... [Pg.2298]

Knockout drums are sometimes called catch tanks or blowdown drums. As illustrated in Figure 8-12, this horizontal knockout drum system serves as a vapor-liquid separator as well as... [Pg.371]

Determine the maximum vapor velocity in a horizontal knockout drum to dropout liquid particles with particle diameters of 300 pm, where... [Pg.374]

Determine the vapor velocity inside a horizontal knockout drum for the following three... [Pg.380]

A practical formula for obtaining the required diameter of horizontal knockout drums (based on 400 microns particle size) is... [Pg.172]

A vessel handling large amounts of liquid or a large liquid surge volume will usually be horizontal. Also, where water must be separated from hydrocarbon liquid, the vessel will be horizontal. A vessel with small surge volume such as a compressor knockout drum will usually be vertical. [Pg.133]

Gravity Separators Three types of gravity separators are commonly used in the chemical process industries (CPI) horizontal blowdown drum/catch tank, vertical blowdown drum/catch tank, and multireactor knockout drum/catch tank. [Pg.80]

Multireactor Knockout Drum/Catch Tank The area needed for vapor disengaging is calculated by the equations given earlier in the section on horizontal blowdown drums. The diameter and length (or height) are determined by considering a number of factors ... [Pg.88]

The process engineer is often required to design separators or knockout drums for removing liquids from process gas streams. This chapter reviews the design of horizontal and vertical separators and the sizing of partly filled horizontal and cylindrical vessels. The chapter concludes by reviewing the sizing of a cyclone and a solid-desiccant gas dryer. [Pg.256]

A knockout drum or demister separator may be either a vertical or a horizontal vessel. A vertical vessel is generally preferred because its efficiency does not vary with the liquid level. Alternatively, a horizontal... [Pg.257]

Settling tank knockout drum Gravity Tank (upright or horizontal) Slowing down of the gas flow so much that the settling velocity is higher than the gas velocity. Simple, inexpensive apparatus for very gross drops, poor efficiency, rare use. [Pg.484]
