Abstract
A water-containing fuel boiling in the gasoline boiling range, such as gasoline or gasohol, is contacted with a substantially saturated aqueous solution of potassium fluoride (or carbonate) plus solid potassium fluoride (or carbonate) and dry fuel is recovered.
Claims21
The method of treating a water-containing hydrocarbon charge fuel containing at least one fuel selected from the group consisting of water-containing hydrocarbon fuel boiling in the gasoline boiling range and water-containing gasohol which comprises
- contacting said charge water-containing fuel with a salt selected from the group consisting of potassium fluoride and potassium carbonate thereby forming a multi-phse system including (i) a first phase of supernatant fuel containing less water than is present in said charge fuel and (ii) a second phase containing aqueous solution of said salt;
- and
- recovering said first phase containing less water than is present in said charge fuel.
The method of treating a charge water-containing fuel containing at least one fuel selected from the group consisting of water-containing hydrocarbon fuel boiling in the gasoline boiling range and water-containing gasohol which comprises
- contacting said charge water-containing fuel with a substantially saturated aqueous solution of a salt selected from the group consisting of potassium fluoride and potassium carbonate in the presence of said salt in solid phase thereby forming a multi-phase system including (i) a first phase containing substantially dry fuel and (ii) a second phase containing substantially saturated aqueous solution of said salt;
- and
- recovering said first phase containing substantially dry fuel.
The method of treating a charge water-containing gasohol which comprises
- contacting said charge water-containing gasohol at 40.degree. F.-120.degree. F. with a substantially saturated aqueous solution of potassium fluoride in the presence of solid potassium fluoride thereby forming a multi-phase system including (i) a first phase containing substantially dry gasohol and (ii) a second phase containing substantially saturated aqueous solution of potassium fluoride;
- and
- recovering said first phase containing substantially dry gasohol.
The method of treating a water-containing hydrocarbon charge containing at least one fuel selected from the group consisting of water-containing hydrocarbon fuel boiling in the gasoline boiling range and water-containing gasohol which comprises
- passing a mixture of (i) said water-containing fuel and (ii) a substantially saturated aqueous solution of potassium fluoride through a bed of solid potassium fluoride thereby forming a multi-phase system including (i) a first phase containing substantially dry fuel and (ii) a second phase containing substantially saturated aqueous solution of potassium fluoride;
- withdrawing said multi-phase system from said bed of said potassium fluoride;
- separating said first phase and said second phase in said withdrawn multi-phase system;
- and
- recovering said first phase containing substantially dry fuel.
