Abstract

A process for the production of synthesis gas by partial combustion of a hydrocarbon feed using a burner with a plurality of coaxial channels, the method comprising the following steps: supplying a non-gaseous hydrocarbon feed using at least one of the plurality of coaxial channels; supplying a gaseous hydrocarbon feed using at least one of the plurality of coaxial channels; supplying an oxidizer gas using at least one of the plurality of coaxial channels; separately supplying a moderator gas using at least one of the plurality of coaxial channels; arranging the at least one channel supplying the non-gaseous hydrocarbon feed between two adjacent channels among the plurality of coaxial channels, wherein the two adjacent channels both supplying a flow containing the gaseous hydrocarbon feed or respectively supplying a flow containing the gaseous hydrocarbon feed and a flow of the moderator gas.

First claim

That which is claimed is:

1. A process for the production of synthesis gas by partial combustion of a hydrocarbon feed using a burner with a plurality of coaxial channels, the method comprising the following steps:
supplying a non-gaseous hydrocarbon feed using at least one of the plurality of coaxial channels;
supplying a gaseous hydrocarbon feed using at least one of the plurality of coaxial channels;
supplying an oxidizer gas using at least one of the plurality of coaxial channels;
separately supplying a moderator gas using at least one of the plurality of coaxial channels;
arranging the at least one channel supplying the non-gaseous hydrocarbon feed between two adjacent channels among the plurality of coaxial channels,
wherein the two adjacent channels both supplying a flow containing the gaseous hydrocarbon feed or respectively supplying a flow containing the gaseous hydrocarbon feed and a flow of the moderator gas.

2. A process according to claim 1 , wherein the gaseous hydrocarbon feed is at least partly supplied via a central channel among the plurality of coaxial channels.

3. A process according to claim 1 , wherein the gaseous hydrocarbon feed is at least partly supplied via an outer channel among the plurality of coaxial channels.

4. A process according to claim 1 , wherein the gaseous hydrocarbon feed is supplied via only one of the plurality of coaxial channels.

5. A process according to claim 1 , wherein the gaseous hydrocarbon feed is a mixture of steam and a hydrocarbon gas.

6. A process according to claim 5 , wherein the gaseous hydrocarbon feed has a hydrocarbon gas content in the range of 30-70 wt. %.

7. A process according to claim 1 , wherein the gaseous hydrocarbon feed is natural gas.

8. A process according to claim 1 , wherein the moderator gas is steam.

9. A process according to claim 1 using a burner with coaxial channels including:
a first inner central channel supplying a gaseous hydrocarbon feed,
an adjacent annular second channel supplying an oxidizer gas,
a third channel supplying a flow of steam,
a fourth channel supplying a flow containing oil,
a fifth channel supplying a flow of steam,
a sixth channel supplying an oxidizer gas and
an outer seventh channel supplying a gaseous hydrocarbon feed.

10. A process according to claim 1 using a burner with coaxial channels including:
a first inner central channel supplying a first flow of an oxidizer gas,
an adjacent annular second channel supplying a second flow of an oxidizer gas with a flow rate which is higher than the flow rate of the first flow;
a third channel supplying a flow of steam,
a fourth channel supplying a flow containing oil,
an outer fifth channel supplying a gaseous hydrocarbon feed.

11. A process according to claim 1 wherein,
the at least one channel supplying the gaseous hydrocarbon feed includes a first inner central channel and an outer seventh channel;
the at least one channel supplying the oxidizer gas includes an adjacent annular second channel and a sixth channel;
the at least one channel separately supplying the moderator gas includes a third channel and a fifth channel each providing a flow of steam;
the at least one channel supply the non-gaseous hydrocarbon feed includes a fourth channel supplying a flow containing oil.

12. A process according to claim 1 wherein,
the at least one channel supplying the moderator gas includes a first inner central channel supplying a first flow of the oxidizer gas, and an adjacent annular second channel supplying a second flow of the oxidizer gas with a flow rate which is higher than the flow rate of the first flow;
the at least one channel separately supplying the moderator gas includes a third channel supplying a flow of steam;
the at least one channel supplying the non-gaseous hydrocarbon feed includes a fourth channel supplying a flow containing oil;
the at least one channel supplying the gaseous hydrocarbon feed includes an outer fifth channel.
