30). If water is used, it is very important that clean treated water be used. Untreated river water is not acceptable because excessive deposits and fouling buildup will occur in the cylinder jackets, creating serious damage from cylinder overheating. A closed cooling system with a tempered water–glycol mixture is highly recommended to minimize deposits and prevent liquid dropout from saturated gases in the cylinders. A typical cooling system as shown in Fig. 31 may be used for one or more units.
Although certain claims and counterclaims are made by the various manufacturers, they share a desire to provide durable configurations compatible with gas composition and pressure. Also, valves are almost always symmetrically placed around the outer circumference of the cylinder and can normally be removed and serviced from the outside. Good specifications mandate configurations and arrangements that will preclude installation errors. 36 Cutaway of the closed and open positions of a damped plate valve, illustrating the pneumatic damping feature.
45) In all the preceding, pressure is lb/in2 absolute. If water vapor is a component in the gas analysis and the total analysis percentage amounts to 100, the preceding equations may be applied to the wet gas. Use the proper value for M in Eq. 43), however. Often, water vapor is segregated, and the space it occupies must be included separately. 8). 46) where pv is the actual vapor pressure of the contained moisture. 26 CYLINDER CLEARANCE AND VOLUMETRIC EFFICIENCY Cylinder clearance cannot be eliminated completely.
