Design safety centrifuges

A good discussion of centrifuge safety design features and operating practices is found in an IChemE publication (1987). 

Ancillary equipment, designed for at least 2.5 MPa (25 bar) meters and flow controls for pressurized ammonia feed and effluent streams centrifugal pumps for discharging into liquid ammonia supply piping and for liquid ammonia loading equipment for safe pressure relief for ammonia vapor and inerts (see Fig. 118 and [1268]). Design of pressure storage tanks and the related safety aspects are discussed in [1270]. 

Equipment is considered the primary barrier for protection of the employees. Items such as biosafety cabinets, safety centrifuges, enclosed containers, impervious work surfaces, autoclaves, foot-operated sinks, and other equipment specifically designed to prevent direct contact with infectious organisms or with aerosols must be available. Personal protective equipment can also be considered as an effective secondary barrier if engineering controls are not sufficient. These latter items can include, at minimum, a lab coat or wrap-around gown, possibly gloves, masks, or respirators, goggles, and head and foot covers. 

Centrifugal. Good practice allow safety margins of design speed 5 %, design head 10 % and design power 15 %. The sonic velocity decreases with an increase in gas... 

This section highlights additional features to consider in the design of a centrifugal or reciprocating com-Messor layout. There are many ways to develop a ompressor layout, but certain aspects of these marines dictate how best to approach a design that opti- nizes operation, maintenance, and safety while adher-ng to economic requirements.
