Abstract
A carbon foam evaporator is described which can be used in a wide variety of operating conditions. The evaporator utilizes a carbon foam with a bi-model pore distribution. The carbon foam is thermally stable up to temperatures of at least 300° C., is rigid, and has a compressive strength of at least 100 psi. The carbon foam is also resistant to chemical attacks.
Claims21
An evaporator comprising:
- a carbon foam body having a multiplicity of pores and having a bimodal pore distribution wherein at least about 90% of the pores by volume have a diameter of between about 10 microns and about 150 microns and at least about 0.5% of the pores by volume have a diameter between about 0.8 microns and about 3.5 microns;
- a liquid introducer arranged to direct a liquid to the carbon foam body;
- a liquid collector arranged to collect liquid from the carbon foam body;
- and
- a gas provider operably associated with the carbon foam body for providing a gas to the carbon foam body.
