Centrifugal compressor compression ammonia or syngas (often contains large amounts of ammonia), the system must be kept dry, as to reduce oil and transport gas contact.

采用离心压缩机压缩氨或合成气(常含大量氨)时，系统必须保持干燥，尽可能减少油与输送气接触。

Natural gas that is not in contact with oil in a reservoir. Nonassociated gas is usually dry gas.

在储层中不与油接触的天然气。非伴生天然气通常为干气。

The techniques are as follows: homogeneous oil separation - flocculation precipitation - gas floatation - biological contact oxidation.

其处理工艺为均质隔油-混凝沉降-气浮-生物接触氧化。

The Bureau of Ocean Energy Management requested that NOAA investigate the site after it was originally detected as an "unknown sonar contact" by Shell Oil Company during a 2011 oil and gas survey of the Gulf, government officials said.

Think about what this advancement has meant just in terms of access to the resources: When drilling into a hydrocarbon bearing formation 100 feet thick, vertical drilling would allow an operator to contact 100 feet of rock, which would limit your potential recovery to whatever oil or gas would flow into that length of pipe.
