Technology
In the Red Leaf Resources EcoShale In-Capsule Process a hot gas is generated by burning natural gas or pyrolysis gas. Generated hot gas is then circulated through oil shale rubble using sets of parallel pipes. The heat is transferred to the shale through the pipe walls rather than being injected directly into the rubble, thereby avoiding dilution of the product hydrocarbons with the heating gas. The oil shale rubble is enclosed by a low-cost earthen impoundment structure to prevent environmental contamination and to provide easier and more rapid reclamation after the extraction process is finished. Heat from the spent shale is recovered for enhancing the process's energy efficiency by passing cool gas through pipes and then using it for preheating adjacent capsules.

Famous quotes containing the word technology:
“Our technology forces us to live mythically, but we continue to think fragmentarily, and on single, separate planes.”
—Marshall McLuhan (1911–1980)
“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.”
—Anton Pavlovich Chekhov (1860–1904)
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
