Abstract
An apparatus, method and system remove contaminants from a vapor. In an embodiment, a contaminant removal apparatus includes a vacuum box. The vacuum box is a vessel. The apparatus also includes a demister pad disposed in the vacuum box. A vapor is introduced to the vacuum box on an opposing side of the demister pad from a vapor exit from the vacuum box.
Claims20
A contaminant removal apparatus, comprising:
- a vacuum box, wherein the vacuum box comprises a vessel, wherein the vessel comprises a top surface and a bottom surface;
- a first water removal device disposed in the vacuum box, wherein the first water removal device is disposed perpendicular to the top surface of the vessel, wherein a vapor is introduced to the vacuum box on an opposing side of the first water removal device from a vapor exit from the vacuum box, wherein the first water removal device further comprises a first weir;
- a second water removal device disposed in the vacuum box, wherein the second water removal device is disposed perpendicular to the bottom surface of the vessel, wherein the second water removal device comprises a second weir;
- a third water removal device disposed on the bottom surface of the vessel, wherein the third water removal device comprises a drain;
- a sample port disposed on the drain.
2 more elements
A method for removing contaminants from process equipment, comprising:
- (A) introducing steam to the process equipment to provide a contaminated vapor;
- (B) introducing at least a portion of the contaminated vapor to a first vacuum box, wherein the contaminated vapor comprises steam and hydrocarbons;
- (C) introducing at least a portion of the contaminated vapor to a second vacuum box, wherein the contaminated vapor comprises steam and hydrocarbons;
- (D) removing at least a portion of water from the contaminated vapor, wherein the vacuum box comprises a water removal device, and wherein the water removal device removes water from the contaminated vapor to provide water and a reduced water vapor;
- (E) removing at least a portion of the water and the reduced water vapor from the first vacuum box, wherein the reduced water vapor is removed from an opposing side of the first vacuum box from a side of the first vacuum box at which the contaminated water is introduced to the first vacuum box;
- (F) introducing at least a portion of the reduced water vapor from the first vacuum box to a first distributor, wherein the first distributor separates the reduced water vapor into an at least one different vapor stream;
- (G) removing at least a portion of the water and the reduced water vapor from the second vacuum box, wherein the reduced water vapor is removed from an opposing side of the second vacuum box from a side of the second vacuum box at which the contaminated water is introduced to the first vacuum box;
- (H) removing at least a portion of water from the contaminated vapor, wherein the second vacuum box comprises a second water removal device, and wherein the second water removal device removes water from the contaminated vapor to provide water and a reduced water vapor;
- (I) introducing at least a portion of the reduced water vapor from the second vacuum box to a second distributor, wherein the second distributor separates the reduced water vapor into an at least one different vapor stream;
- and
- (J) introducing the at least one different vapor stream to a thermal destruction device.
