## Abstract

Devices, systems, and methods for siphoning heat exchange or reaction for solids production are disclosed. Passing a contact fluid through a siphoning device, wherein the siphoning device is made of a contact fluid inlet, a carrier fluid inlet, and an outlet, and wherein the contact fluid passes through the contact fluid inlet, inducing a siphon in the carrier fluid inlet. This siphon then siphons a carrier fluid through the carrier fluid inlet and into the contact fluid. The carrier fluid is, in part, made of a first component. The carrier fluid and the contact fluid mix. This mixing produces a product solid, wherein the product solid is produced from the first component by desublimation, condensation, solidification, crystallization, precipitation, reaction with the contact fluid, or a combination thereof of at least a portion of the first component. The product solid passes through the outlet.

## Claims

### Claim 1
