6) reported Henry's constant for hydrocarbons including butane and isobutane
in molten polypropylene and polystyrene.
In addition to the above the report determines isobutane
consumers in the market.
Enterprise owns and/or operates among the largest natural gas liquids fractionation facilities and MTBE facilities in the United States, the largest isobutane
complex in the United States, two propylene fractionation facilities, an import/export terminal, approximately 35 million barrels of storage capacity and network of approximately 500 miles of pipelines, all situated along the Gulf Coast.
will also use Honeywell s UOP Butamer process which converts normal butane to isobutane
thereby maximizing the feedstock utilization to the UOP Oleflex process.
Unit capacity will be 83 KBD and will utilize mixed butylenes and isobutane
As a nucleating agent, it is recommended for direct-gas systems using freons, pentane, butane, isobutane
, nitrogen and carbon dioxide.
Loop reactors use isobutane
as a diluent; tanks use hexane.
The facility will use UOP C3 Oleflex(TM) process technology to produce 750,000 metric tons of propylene from propane annually and the UOP Butamer(TM) process to produce 565,000 metric tons of isobutane
has been widely used in household refrigerators in Europe and parts of Asia for several years.
will use the UOP Butamer process to transform normal butane to isobutane
and UOP s C3/C4 Oleflex process to convert isobutane
to isobutylene and propane to propylene for the production of plastics.
The key to the technology is use of inert gases like carbon dioxide or nitrogen that are more "environmentally friendly" than ozone-depleting fluorocarbons and smog-causing hydrocarbons like pentane or isobutane
The announcement comes as the Company awaits a final rule from the Environmental Protection Agency (EPA) in connection with its request for approval to use isobutane
as a refrigerant in household refrigerators.
