Drum sizes

Occasionally, a small clean-up of a few tons may occur. These are usually handled via placing the waste in open-topped drums that are sealed with a hd and ring closure. Consultation with the ultimate treatment facihty is important to select the correct drum size and material and eliminate the need for repackaging the waste. 

The arrangement in Figure 5-14, generally called back to back," is normally considered useful in solving difficult thrust balance problems where the conventional thrust bearing and balance drum size are inade... 

Recommended Feed Volumes. Both feed volume and magnetic solids discharge rate should be balanced in selecting media recovery drum size. The feed rates typically recommended for single and double wet drum separators depend on drum diameter. For a 762 mm dia single drum, the recommended feed rate is 50—55 m3/(hrn) for either a 914 mm dia single drum or a 762 mm dia double drum, 55—70 m3/(h-m) for a 914 mm dia double drum, 70—95 m3/(h-m). 

Reducing relief drum size is also related to the frequency of gas release, offshore. The normal method of sizing ... 

To see if this drum size can be significandy reduced using the approach proposed in this article, some additional information is needed and the following is assumed inlet nozzle angle 0,=3O deg. inlet nozzle dia. vapor-droplet velocity ( , 56.6 ft/s hence. t/ = L cos 0,=49 ft/s, and Lp— stn 0,=28.6 ft/s. (The parameters 0( and dn can. of course, be adjusted. The effects of varying these parameters will be discussed.)... 

Conventional design methods and the AI l-521 procedure will violet oversized drums, because of the omission of the droplet deceleration in the x and y directions. Without the nozzle extension, the approach being proposed would have yielded a drum size not larger than C ft... 

A wire-mesh pad in a horizontal drum greatly enhances separation and significantly reduces drum size. For lower pressure drop across the pad. the requirement for a high-performance pad can be relaxed by designing so the vapor space removes larger droplets, reducing the load on the pad.
