Spacing is the primary means of fire protection for most refrigerated flammable liquid or gas storage vessels. Refer to CCPS Guidelines for Facility Siting and Layout (CCPS, 2003b). 

A practical limitation comes from the loading capacity of modem analytical balances. It is difficult to find a balance with a sensitivity of 0.1 mg and a loading capacity of more than c. 300 g. This means that the stainless steel gas storage vessels...

Secondary components of the system are a gas processing train and gas storage vessel. The gas processing train can include different components such as scrubbers, catalytic combiners, coalescers, filters and flashback arrestors. Its purpose is to remove particulate contamination, purify the gas stream, and remove excess water or other liquids. 

The flow controls for the new flare test facility were particularly challenging for several reasons. One was the wide range of fuels and flow rates that it would have to handle. The system is capable of flowing less than 100 Ib/hr (45 kg/hr) up to more than 150,000 Ib/hr (70,000 kg/hr). Another challenge was the extremely fast response time required. The system must reach the desired flow rate quickly and then maintain that rate as the pressure rapidly declines in the gas storage vessel.

An instrument for volumetric measurements of pure gas adsorption basically consists of a gas storage vessel (volume Vsv) and an adsorption chamber (Vac) being connected by a tube bearing a valve. Both vessels should completely be placed within a thermostat (water, oil, air etc.) and provided with tubes for gas supply and evacuation as well as with thermometers and manometers to measure the temperature (T) and pressure (p) inside the vessels, cp. Figure 2.1.

In this section we would like to address in brief the problem of wall adsorption. By this we understand the phenomenon that any gas or Uquid contacting the inner surfaces of vessels, tubes, valves etc. of any device will be adsorbed to a certain, though normally only tiny, amount on them. This phenomenon first has observed in gas thermometers at very low temperatures i. e. low gas pressures [4.20]. Here it added considerably to the uncertainties of measurements. The same can be tme for volumetric or volumetric-gravimetric adsorption measurements at low pressures or if only very small amounts of sorbent material - say 100 mg or less - are available, cp. Chap. 2. Therefore it sometimes may be necessary in setting up mass balances for adsorption measurements to take this phenomenon into account. A possibihty to do this is to measure it. This on principle can be done by using the instrument sketched in Fig. 4.20 below. It mainly consists on three parts a gas storage vessel (SV) equipped with a piston to change its volume (Vsv) and...

Water-spray fixed systems are generally used to protect flammable liquid and gas storage vessels piping and equipment electrical equipment such as transformers, oil switches, and rotating electrical machinery and openings in firewalls and floors through which conveyors pass. The type of water spray required for any particular hazard depends, of course, on the nature of the hazard and the piupose for which the protection is provided. 

If a methane fire should occur, shut off the gas source if this can be done without risk. If the source cannot be shut off, let the fire burn itself out while making sure that gas storage vessels and piping containing gas in close proximity, as well as combustible materials in the area, are kept cool by spraying with water. The local fire department should be called. 

The most simple and still fairly reliable method to measure multi-component gas adsorption equilibria is the volumetric-chromatographic method. The basic installation for this method is sketched in Figure 1. It basically consists of a gas storage vessel of volume (Vsv) and an adsorption chamber of volume (Vac) filled with adsorbent of mass (m ) and provided with proper tubing and valves to allow gas circulation and evacuation. The gas (mixture) is first prepared in the storage vessel and then expanded to the adsorption vessel where it is partly adsorbed in the sorbent material.
