Synthesis gas for FT synthesis is produced using a producing apparatus including an active carbon adsorbing vessel for adsorbing impurities in a natural gas, a hydro-desulfurizer for hydrogenating and desulfurizing sulfur content in the natural gas under a condition of a partial pressure of hydrogen of 100 to 200 kPa, a second hydrogen supplying line for supplying hydrogen to the natural gas between the hydro-desulfurizer and a reactor, the reactor for obtaining synthesis gas by reacting the natural gas, carbon dioxide and steam in the presence of a catalyst for reforming, and a heat recovering boiler for cooling the synthesis gas at a cooling rate of 2000 to 4000&#xb0; C./second.

Process for producing synthesis gas for the fischer-tropsch synthesis and producing apparatus thereof

A device for controlling a liquid flow in a vertically extending pipe is disclosed which includes a plate member horizontally disposed in the pipe for receiving the liquid flow thereon and having an opening to permit the liquid received on the plate member to pass therethrough, a tubular guide downwardly inwardly extending from the periphery of the opening and terminating to form a liquid outlet, and a plurality of partition plates disposed on the tubular guide. Each partition plate has an upper end upwardly protruding from the periphery of the opening and a lower end obliquely downwardly extending from the periphery of the opening along the wall of the tubular guide member, so that a plurality of discrete passages are defined on the tubular guide. A cover plate is provided to cover the passages so that the liquid received on the plate member flows through the passages and is discharged from the liquid outlet of the tubular guide to form a vortex flow.

A gas separation process and a unit therefor. The process comprises the steps of: introducing a gas consisting of two or more components into an adsorption system in which adsorbent particles circulate in a fluidized state, thereby to allow, at atmospheric pressure or an elevated pressure, the adsorbent particles to adsorb a gas component to be separated from the gas; transferring the adsorbent particles adsorbing the gas component to a desorption system; and then desorbing the gas component from the adsorbent particles in the desorption system which is regulated to have either a lower pressure or a lower pressure and a higher temperature than the adsorption system.
