Problems solved by technology

The pilot burner must be removed or pulled out of the furnace after the preheating process has been completed and before the main burner is put into operation, as there is a risk of damage to the pilot burner due to the high temperature of the main burner flame for the sake of

Embodiment Construction

[0037] figure 1 A prior art burner 10 for combustion of hydrogen sulphide by oxygen is schematically shown. A corresponding heat treatment takes place in a furnace 40 equipped with main burners 10 and pilot burners 50 . Such as figure 1 The large unit shown requires a start-up procedure for preheating the furnace 40 to avoid thermal stress on the refractory lining of the furnace 40 . The preheating process is controlled by a pilot burner 50 which is installed separately from and close to the main burner 10 . The thermal energy rate of the preheating process is usually about 50K / h, and the preheating is stopped when the temperature of the furnace container reaches a temperature of about 1000-1100°C. Before putting the main burner 10 into operation, the pilot burner 50 must be retracted or pulled entirely out of the furnace 40 due to the risk of damage to the pilot burner 50 due to the high temperature of the main burner flame.

Abstract

The present invention relates to a method of combusting hydrogen sulfide (H2S) with oxygen by means of a burner and to such a burner, the outlet of which being connected to a furnace which is heated by a burner flame, said method including the step of preheating the furnace, wherein during the preheating step, a first fuel gas is supplied through a first port of the burner, the first port being connected to a plurality of first tubes extending to the burner outlet, a first oxidant gas is supplied through a second port of the burner, the second port being connected to a plurality of second tubes spaced from and coaxial with the first tubes, and a second oxidant gas or second fuel gas is supplied through a third port of the burner, the third port being connected to a plurality of third tubesspaced from and coaxial with the second tubes.

Description

technical field [0001] The present invention relates to a method for burning hydrogen sulfide (H 2 S) The method and the burner, the outlet of which is connected to the furnace, which is heated by the burner flame of the step of preheating the furnace. More generally, the invention relates to the partial oxidation (partial combustion) of hydrogen sulfide to form sulfur. Background technique [0002] Hydrogen sulfide-containing gas streams (also referred to herein as "sour gas streams") are especially formed in oil refineries and natural gas processing units. Because hydrogen sulfide is toxic, this stream cannot be vented directly into the atmosphere. A conventional method for treating gas streams containing hydrogen sulphide is the well known Claus process. In this process, a portion of the hydrogen sulfide contained in the gas stream is mixed with an oxidant gas, such as air, and burned in a furnace to form sulfur dioxide, which then reacts in the furnace with the remain...
