Abstract

A process to control the amount of N-contaminant is synthesis gas which is fed into a Fischer-Tropsch reactor and which utilizes Fischer-Tropsch produced water is provided. A process which utilizes a countercurrent flow of Fischer-Tropsch produced water produced in a downstream Fischer-Tropsch reactor to wash syngas being fed to an upstream Fischer-Tropsch reactor is provided.

Claims

AMENDED CLAIMS received by the International Bureau on 14 July 2006 (14.07.2006)
5. A Fischer-Tropsch process comprising the steps of:
(a) introducing a feed syngas stream into a first-stage Fischer-Tropsch reactor and recovering a first overhead stream comprised of Fischer-Tropsch produced water, hydrocarbon product and unreacted syngas from the first stage Fischer-Tropsch reactor;
(b) separating the unreacted syngas component from the first overhead stream and introducing the unreacted syngas component into a second stage Fischer-Tropsch reactor;
(c) recovering a second overhead stream comprised of Fischer-Tropsch produced water and hydrocarbon product from the second stage Fischer-Tropsch reactor;
(d) separating and cooling the Fischer-Tropsch produced water from the second overhead stream; and
(e) mixing the Fischer-Tropsch produced water separated in step (d) with the first overhead stream.
6. The process of claim 5 wherein the mixing step (e) occurs prior to the separation step (b).
7. The process of claim 5 wherein the mixing step (e) occurs simultaneously with the separation step (b).
8. The process of claim 5 further comprising the steps of:
(i) separating the Fischer-Tropsch produced water from the first overhead stream;
(ii) feeding the Fischer-Tropsch produced water separated in step (i) and a raw syngas stream into a first absorber; and
(iii) recovering a washed syngas stream from the first absorber.
9. The process of claim 8 wherein the washed syngas stream from the first absorber is used as the feed syngas stream in step (a).
10. The process of claim 5 wherein the first and second stage Fischer-Tropsch reactors contain a catalyst comprising cobalt.
11. The process of claim 5 wherein the syngas stream is produced in the presence of air or oxygen-enriched air.
12. In a Fischer-Tropsch process wherein a synthesis gas is catalytically converted into a Fischer-Tropsch reaction product mixture and wherein two or more Fischer-Tropsch 1 1 reactors are used in the process, the process improvement of improved N- contaminaπts absorption comprising:
(a) separating acidic Fischer-Tropsch produced water from the Fischer- Tropsch reaction product mixture of a first Fischer-Tropsch reactor; and
(b) mixing the separated acidic Fischer-Tropsch water from step (a) with the feed to a second Fischer-Tropsch reactor wherein the second Fischer-Tropsch reactor is the same as the first Fischer-Tropsch reactor or is located upstream of the first Fischer- Tropsch reactor.
13. The process improvement of claim 12 wherein the synthesis gas is produced in the presence of air or oxygen-enriched air.
14. The process improvement of claim 12 wherein the Fischer-Tropsch reactors contain a catalyst comprising cobalt.
