METHOD FOR EFFICIENT USE OF HEAT FROM TUBULAR REFORMER

摘要

This invention provides a method for effectively utilizing heat in a tubular reformer which, in using a steam reforming method or a carbon dioxide reforming method in a reforming step in a GTL process for producing various hydrocarbon oils from natural gas, can improve the thermal utilization efficiency. The method comprises a synthesis gas producing step of passing natural gas and steam and/or carbon dioxide gas through a tubular reformer packed with a reforming catalyst to convert them to a synthesis gas, a Fischer-Tropsh oil producing step of subjecting the produced synthesis gas to a Fischer-Tropsh reaction to produce a Fischer-Tropsh oil, and an upgrading step of hydrogenating and distilling the produced Fischer-Tropsh oil to produce various hydrocarbon oils. Excess heat produced in the synthesis gas production process is recovered, and the recovered heat is used as heat for hydrogenation and/or distillation in the upgrading step.
