METHOD FOR STARTING-UP A GAS TO LIQUID PROCESS

摘要

The invention relates to a process for starting up a gas-to-liquid process including the production of synthesis gas and a downstream GTL process. The synthesis gas is produced by the use of autothermal reforming (ATR) or catalytic partial oxidation (CPO) and during the starting period the effluent gas from the ATR or CPO is significantly changed to form an off-gas recycle which is fed to the ATR or CPO. When the downstream GTL process is running, the recycle to ATR or CPO is shifted to its off-gas.
