Method of transferring fluent material with compressed gas
First Claim
1. A method of transferring a fluent material from a point of origin to a fluent material transfer destination, comprising the steps of:
- a) at the point of origin, alternately supplying quantities of the fluent material to be transferred and quantities of compressed gas to a pipeline at the point of origin so that the quantities of fluent material are transferred together with the quantities of compressed gas through the pipeline to the fluent material transfer destination;
b) at the fluent material transfer destination, receiving the quantities of fluent material and the quantities of compressed gas from the pipeline in to a receiver tank; and
c) returning the gas in the receiver tank at the fluent material transfer destination to the point of origin for reuse.

Abstract
A method of transferring fluent material transfers the material from a first pressure tank to a fluent material transfer destination by supplying compressed gas to the first tank through a compressor. The compressed gas is retained in the first tank for reuse. Additional fluent material is drawn into a second pressure tank and is transferred therefrom to the fluent material transfer destination by supplying the compressed gas from the first pressure tank to the second pressure tank through the compressor. The compressed gas is further retained in the second pressure tank transferring fluent material from the first pressure tank. As the compressed gas is emptied from each tank to the other tank, additional fluent material is drawn into that tank. The cycle can be repeated on a continuous basis to transfer large quantities of fluent material.

10. A method of transferring a fluent material, comprising the steps of:
-
a) transferring a quantity of fluent material from a first tank to a fluent material destination by supplying compressed gas to the first tank from a compressor until the compressed gas has replaced the quantity of fluent material; b) supplying compressed gas to the compressor from a second tank having compressed gas therein until the gas pressure in the second tank reaches atmospheric pressure; c) drawing gas from a third tank having gas therein at atmospheric pressure with the compressor and supplying a quantity of fluent material to the third tank; d) transferring the quantity of fluent material from the third tank to the fluent material destination by supplying compressed gas to the third tank from the compressor until the compressed gas has replaced the quantity of fluent material in the third tank; e) supplying compressed gas to the compressor from the first tank now having compressed gas therein until the gas pressure in the first tank reaches atmospheric pressure; f) drawing gas from the second tank having gas therein at atmospheric pressure with the compressor and supplying additional fluent material to the second tank; g) transferring the quantity of fluent material from the second tank to the fluent material destination by supplying compressed gas to the second tank from the compressor until the compressed gas has replaced the quantity of fluent material in the second tank; h) supplying compressed gas to the compressor from the third tank now having compressed gas therein until the gas pressure in the third tank reaches atmospheric pressure; and i) drawing gas from the first tank having gas therein at atmospheric pressure with the compressor and supplying additional fluent material to the first tank. - View Dependent Claims (11, 12, 13, 14, 15)
