Absorber: In the absorber column the refrigerated feed gas and lean oil
are intermingled at a temperature of minus 35 deg F to allow the lean oil
to absorb the LPG products of propane and heavier components from the gas and become a rich oil.
The lean oil
shale layer, lying under the rich oil shale, has the average thickness of about 30 m.
However, leading research institutes are not expecting oil markets to "nose-drive," as in 1998, because of relatively lean oil
The completed expansion makes the facility one of the largest natural gas liquids producers in the United States and enabled Williams to shut down a 1950s-era lean oil
processing unit that will remain available for incremental volumes in the future.
The process is suitable for retorting high-calorific oil shales (over 15% of Fischer assay oil) and bituminizing oil shales as well as for lean oil
The Jonesville Gas Processing Plant is a refrigerated lean oil
plant with a capacity of 28 million cubic feet per day.
The system's high- and low-pressure lines range in size from 4-inches to 14 inches and connect approximately 200 wells to the refrigerated lean oil
The plant commenced operations on March 31, 1994, replacing existing refrigerated lean oil
gas processing operations and is currently processing approximately 40 million cubic feet of natural gas per day.
Since a single technology does not fit all applications, PetroGas developed Lean Oil
Absorption, Refrigeration, Carbon Adsorption, cryogenic and turboexpander type systems.
As a part of this effort, the company is moving two cryogenic plants to Lincoln Parish, Louisiana to replace existing refrigerated lean oil
It is designed especially for today's large bore, high output engines with oil injection systems, that operate with lean oil
ratios and unleaded fuel.
This may involve the use of new technology and the potential upgrade of the lean oil
system at the central gas plants.
