Methods for granular scavenger material transfer
A method for cleaning a reactor, the method including circulating a fluid inside the reactor, pumping the fluid from the reactor into an inlet of a tank cleaner, and removing solids from the fluid to produce a clean fluid. The method further includes transferring the clean fluid to the reactor and transferring pneumatically the removed solids to a pressurized vessel. Also, a method for transferring spent granular material, the method including providing a vacuum system disposed at a hydrocarbon production site to remove spent material from a reactor, transferring the spent material through the vacuum system into a pressurized vessel, and conveying pneumatically the spent material from the pressurized vessel to a second pressurized vessel.
1. A method comprising:
providing a vacuum system disposed at a hydrocarbon production site to remove spent granular material from a reactor;
transferring the spent granular material through the vacuum system into a pressurized transference device;
conveying, through a first positive pneumatic transfer, the spent granular material from the pressurized transference device to a first pressurized vessel; and
conveying, through a second positive pneumatic transfer, the spent granular material from the first pressurized vessel to a second pressurized vessel.
2. The method of claim 1 , wherein the second pressurized vessel is disposed on a transport vessel.
3. The method of claim 1 , wherein the spent granular material is transferred pneumatically in dense phase.
4. The method of claim 1 , wherein the granular material is transferred pneumatically in lean phase.
5. The method of claim 1 , wherein the first pressurized vessel is disposed on an offshore production site.
6. The method of claim 1 , wherein the spent material is granular H2S scavenger material.
7. A method comprising:
providing a first pressurized vessel containing granular scavenger material;
connecting the first pressurized vessel to a second vessel; and
transferring pneumatically, via compressed air, the granular scavenger material through a plurality of baffles corresponding to complementary outlets in the first pressurized vessel to the second vessel.
8. The method of claim 7 , wherein the second vessel comprises a pressurized vessel.
9. The method of claim 8 , wherein the first pressurized vessel is configured to transfer the granular scavenger material from the first pressurized vessel to the second pressurized vessel as a dense phase.
10. The method of claim 7 , wherein the first pressurized vessel is configured to transfer the scavenger material from the first pressurized vessel to the second pressurized vessel as a lean phase.
11. The method of claim 8 , further comprising:
transferring, via compressed air, the granular scavenger material from the second pressurized vessel to a reactor.
12. The method of claim 11 , wherein the second pressurized vessel is disposed on a transport vessel.
13. The method of claim 8 , wherein a third pressurized vessel is disposed on a production platform and is configured to pneumatically transfer, via compressed air, the granular scavenger material from the second pressurized vessel to the third pressurized vessel.
14. The method of claim 1 , further comprising conveying the spent granular material through a plurality of baffles corresponding to complementary outlets in at least one of the first pressurized vessel and the second pressurized vessel.
15. The method of claim 1 , wherein the second pneumatic transfer comprises transferring the spent granular material through a lower angled section of the first pressurized vessel into the second pressurized vessel.
16. The method of claim 1 , further comprising transferring the spent granular material from the vacuum system to an inlet disposed on an upper portion of the pressurized transference device.
17. The method of claim 7 , wherein the second vessel comprises a plurality of baffles corresponding to complementary outlets therein.
18. The method of claim 7 , further comprising conveying the granular scavenger material through a lower angled section of the first pressurized vessel into the second vessel.
19. The method of claim 7 , wherein the first pressurize vessel is connected to an inlet disposed on an upper portion of the second vessel.
20. The method of claim 7 , further comprising conveying the granular scavenger material from a land based facility into the first pressurized vessel, and
transporting the first pressurized vessel with a transport vessel to an offshore production site.
