Abstract
A method, including: flowing a fluid stream including one or more freezable components over a cooled surface, wherein the cooled surface has a cooled surface temperature below a freezing temperature where at least one of the freezable components solidifies out of the fluid stream as a frozen deposit on the cooled surface; separating the frozen deposit from the cooled surface by mechanically deforming at least part of the cooled surface; and heating the frozen deposit separated from the cooled surface to melt, vaporize, or sublimate the frozen deposit.
Claims24
A method, comprising:
- flowing a fluid stream including one or more freezable components over a cooled surface, wherein the cooled surface has a cooled surface temperature below a freezing temperature where at least one of the freezable components solidifies out of the fluid stream as a frozen deposit on the cooled surface;
- separating the frozen deposit from the cooled surface by mechanically deforming at least part of the cooled surface;
- and
- heating the frozen deposit separated from the cooled surface to melt, vaporize, or sublimate the frozen deposit.

A heat exchanger, comprising:
- an inlet port that receives a fluid stream that includes freezable components;
- a cooled surface over which the fluid stream passes,
- wherein the cooled surface has a cooled surface temperature below a freezing temperature where at least one of the freezable components solidifies out of the fluid stream as a frozen deposit on the cooled surface, and
- the cooled surface comprises a coolant-carrying tube with a shape comprising a helical structure, a series of loops, or a series of sinusoidal bends;
- a deforming device that mechanically deforms the cooled surface causing the frozen deposit to separate from the cooled surface,
- wherein the deforming device bends, elongates, compresses, expands, or torques the cooled surface within an elastic tolerance of the cooled surface;
- and
- an outlet port through which the fluid stream, with a reduction of the freezable components, exits the heat exchanger.

A separation system, comprising:
- a deformable heat exchanger that includes,
- an inlet port that receives a fluid stream that includes freezable components,
- a cooled surface over which the fluid stream passes,
- wherein the cooled surface has a cooled surface temperature below a freezing temperature where at least one of the freezable components solidifies out of the fluid stream as a frozen deposit on the cooled surface, and
- a deforming device that mechanically deforms the cooled surface and separates the frozen deposit from the cooled surface, and
- an outlet port through which the fluid stream, with a reduction of the freezable components, exits the deformable heat exchanger,
- wherein the deforming device bends, elongates, compresses, expands, or torques the cooled surface within an elastic tolerance of the cooled surface;
- a secondary heat exchanger that cross-heat exchanges coolant exiting the deformable heat exchanger with the fluid stream that has exited the deformable heat exchanger;
- a refrigeration unit that cools the coolant that has exited the secondary heat exchanger and supplies the coolant to the coolant-carrying tube;
- and
- a heating unit that converts the frozen deposits separated from the cooled surface into a fluid or gas.
