Method of transferring fluent material with compressed gas
First Claim
1. A method of transferring fluent material, comprising the steps of:
- a) transferring fluent material from a first pressure tank to a fluent material transfer destination by supplying compressed gas to the first pressure tank through a compressor;
b) retaining compressed gas in the first pressure tank;
c) drawing fluent material into a second pressure tank; and
d) transferring the fluent material in the second pressure tank to the fluent material transfer destination by supplying the compressed gas from the first pressure tank to the second pressure tank through the compressor;
wherein said step c) occurs at the same time as said step a), and wherein the compressor draws gas from the second pressure tank to draw the fluent material into the second pressure tank and supplies the gas to the first tank as the compressed gas.

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.
