Definitions
- the present invention relates to a new process for converting hydrocarbon gases into hydrocarbon liquids using one of the known processes for the generation of synthesis gas, as well as the Fischer-Tropsch process and in particular a particular step for treating the residual gas resulting from the process.
- This type of GtL conversion is usually done by transformation of basic gaseous or solid hydrocarbon compounds into a synthesis gas mainly comprising H 2 and CO (by partial oxidation using an oxidizing gas and / or reaction with steam water or C0 2 ), then treatment of this synthesis gas according to the Fischer-Tropsch process to obtain a product which, after condensation, leads to the desired liquid hydrocarbon products. During this condensation, a waste gas is produced.
- This waste gas contains low molecular weight hydrocarbon products and unreacted gases. Consequently, it is generally used as fuel in one of the processes of the GtL unit, for example in a gas turbine or a combustion chamber associated with a steam turbine or in an expansion turbine associated with a compressor of the GtL unit.
- waste gas to be burned often far exceeds the fuel demand of the GtL unit.
- the waste gas also includes C0 2 , which decreases the combustion efficiency of the hydrocarbon products and which is released into the atmosphere, which is contrary to compliance with environmental standards.
- the waste gas generally comprises quantities of H 2 and CO that are not converted: it is therefore not economical to burn them.
- WO 01/60773 also describes a process in which the waste gas from the Fischer-Tropsch process is treated to remove the C0 2 therefrom.
- the waste gas with a lower C0 2 content is used as fuel at various places in the unit.
- US 6,306,917 describes a process in which carbon dioxide is removed from the waste gas from the Fischer-Tropsch process. This document also describes the treatment of the waste gas to recover the hydrogen using a membrane and the recycling of this hydrogen in the Fischer-Tropsch reactor. The CO compound is sent to it for combustion.
- the aim of the present invention is to propose a process for converting hydrocarbon gases into hydrocarbon liquids implementing the Fischer-Tropsch process in which the waste gas from this Fischer-Tropsch process is treated so as to avoid economic loss of H 2 and CO by simple combustion.
- Another object is to propose a process for converting hydrocarbon gases into hydrocarbon liquids implementing the Fischer-Tropsch process in which the waste gas is treated so as to make it possible both to avoid the economic loss of H 2 and
- the invention has the advantage of adapting to all types of waste gas. In addition, it allows the reuse in the GtL process of hydrocarbons, which are contained in the waste gas.

- At least one additional gas stream mainly comprising hydrocarbons having a carbon number of at least 2.
- the invention relates to any type of process for converting hydrocarbon gases into hydrocarbon liquids using the Fischer-Tropsch process.
- these hydrocarbon gases result from a reaction for the production of a hydrocarbon synthesis gas (for example by partial oxidation using an oxidizing gas and water vapor).
- This synthesis gas includes hydrogen and CO. It usually comes from a unit for preparing a synthesis gas from natural gas or an associated gas or coal.
- this synthesis gas is subjected to a Fischer-Tropsch reaction by contacting with a catalyst promoting this reaction.
- hydrogen and CO are converted into hydrocarbon compounds of variable chain length according to the following reaction:
- CO + (1 + m / 2n) H 2 - »(1 / n) C n H m + H z O C0 2 is also produced during this reaction; for example, by the following parallel reactions: CO + H 2 0 - »C0 2 + H 2 2 CO - »C0 2 + CA the outlet of the reactor implementing the Fischer-Tropsch process, the temperature of the products is generally lowered from a temperature of around 130 ° C to a temperature of around 90 to 60 ° C so that one obtains on the one hand a condensate, mainly composed of water and hydrocarbon liquids having a carbon number greater than 4, and on the other hand, a waste gas comprising at least hydrogen, carbon monoxide, hydrocarbons having a carbon number of at most 6, carbon dioxide and also generally nitrogen.
