Compressed natural gas

Step 1. Find the suction and discharge volumetric efficiencies using Equations 3.5 and 3.21 with rp = 831/514 = 1.617. The natural gas compressibility values can be obtained by using the gravity/compressibility charts (see Appendix B-29 through B-35) for a specific gravity of. 60. Both Zj and Z2 values are. 93. Applying Equation 3.6, the value of f may be obtained as follows ...

In December 1987, Pacific Gas and Electric (PG E) reported to the Environmental Protection Agency that it had detected levels of chromium (VI) at its natural gas compression station near Hinkley, California, that were ten times higher than those allowed by government standards. These reports devalued land in the community and sparked the curiosity of Erin Brockovich, who was working in a law office as a secretary. Her passionate investigation into...

Dynamic compressors, commercially used for natural gas compression, could be used in case of moderately high compression (p/p° up to 200-300), while alternative volumetric devices are necessary for higher pressure ratios. With respect to... 

There are a number of other possible utihties which may be provided to a laboratory. Among these are natural gas, compressed air, distilled water, vacuum, steam, refrigerated brine, and other gases. In some instances, there are safety issues, such as limitations on the pressure available from a compressed air hne and the need to incorporate provisions for pressure relief, to ensure that personnel will not be injured by explosions due to excess pressure. Often the quahty of the air is more of a problem. The compressor supplying the system should be capable of supplying air which is clear of oil and moisture. Some facilities which have a large, pressurized liquid nitrogen tank at hand, use the vapors from the tank as a source of ultra clean compressed air to clean woik surfaces.

The system design for the hot module has all the processes that need to be run at elevated temperature located within the hot module, whereas systems such as power conditioning, natural gas compression, and so on are located outside the hot module. 

For smaller plants, under 600 tons/day, reciprocating compressors still are used. They often contain several services on a common drive shaft air compression, natural gas compression, synthesis gas compression and recycle, and ammonia compression for regrigeration.
