Real refrigerators actually work with liquids that go into gases so use the latent heat of the liquid, so it doesn't really work like the Joule-Thomson expansion. So this is real.

Sinopec's mostly a downstream refinery business, doing the unglamorous work of turning unprocessed crude oil into fuel, and its options for expansion are limited.

Wide horizontal tabbed folders work better than narrow vertical ones because they allow for greater expansion of tab names.
