Abstract

Cooling a hot product gas with sticky particles which lose their stickiness upon cooling, obtained for example from partly combusting a carbonaceous material, is carried out by passing the produced gas through a cooling section (11) and by injecting into the product gas a frusto-conical annular jet (22) of cooling fluid tapering in the direction (29) of flow of the product gas. <IMAGE>

Description

SPECIFICATION Method and apparatus for cooling a hot product gas The invention relates to a method for cooling a hot product gas containing sticky particles which lose their stickiness upon cooling.
The sticky particles in the hot product gas will cause difficulties in the plant where the product gas is further processed, because undesired deposits of the particles on, for example, walls, valves or outlets will adversely affect the process. Moreover, these deposits are very hard to remove.
The hot product gas may be obtained from partially combusting a carbonaceous material, in which case the product gas will have a temperature in the range of from 1 000,C to 1 800 C. The sticky particles may be partly or completely in the molten state, they may comprise metals, salts or ashes, and, in general, these particles lose their stickiness at a temperature below about 800"C.
It is an object of the present invention to provide a simple method for cooling a hot product gas containing sticky particles which lose their stickiness upon cooling.
To this end the method according to the invention comprises passing the hot product gas through a cooling section, and injecting into the flow of product gas at least one frusto-conical annular jet of cooling fluid tapering in the direction of the flow of the product gas.
The annular jet of cooling fluid causes the product gas to flow through a mixing zone wherein the product gas is cooled because it is intensively mixed with the cooling gas. The mixing zone, which comprises a converging primary part and a diverging secondary part, is surrounded by an annular recirculation zone which separates the sticky particles from the wall of the cooling section.
The invention further relates to an apparatus for carrying out the method for cooling a hot product gas according to the invention, which apparatus comprises a cooling section, inlet conduit means that can be connected to a hot product outlet, and at least one frustoconical cooling fluid conduit tapering in the direction in which, during normal operation, product gas is passed through the apparatus, wherein the circumferential outlet opening(s) of the frusto-conical cooling fluid conduit(s) opens (open) into the apparatus, and wherein the inlet(s) of the frusto-conical cooling fluid conduit(s) can be connected to a supply of cooling fluid.
The method and apparatus according to the invention will now be described in more detail by way of example with reference to the drawings, wherein: Figure 1 shows schematically a longitudinal section of the apparatus having one frustoconical cooling gas conduit; and Figure 2 shows schematically a longitudinal section of the apparatus having two frustoconical cooling gas conduits.
Reference is first made for Fig. 1. The apparatus according to the invention comprises a tubular cooling section 11, inlet conduit means in the form of a tubular inlet conduit 12, and a frusto-conical cooling gas conduit 1 3 which tapers in upward direction.
The walls of the cooling section 11 and of the inlet conduit 1 2 may be made of refractory material or a suitable metal such as steel, and the wall of the frusto-conical cooling gas conduit 1 3 may be made of a suitable metal, such as steel.
The frusto-conical cooling gas conduit 1 3 is connected to an annular conduit 14 which is provided with an inlet conduit 1 5.
During operation of the apparatus the inlet conduit 1 2 of the apparatus is connected to an outlet of hot product gas (not shown) and hot product gas is passed through the cooling section 11, parallel to the central longitudinal axis 1 8 of the cooling section 11 in upward direction (indicated with arrow 19). Moreover, cooling gas is supplied to the inlet conduit 15, which gas leaves the circumferential outlet opening 21 of the frusto-conical cooling gas conduit 1 3 as a frusto-conical annular jet 22 of cooling gas tapering in the direction of the flow of hot product gas, indicated with arrow 19.
The annular jet 22 of cooling gas causes the hot product gas with sticky particles to flow through a mixing zone 23 surrounded by a recirculation zone 24. The mixing zone 23 comprises a converging primary part 25, in which hot product gas is rapidly mixed with cooling gas, and a diverging secondary part 27, in which mixing and cooling is completed in a turbulent jet.
At the end of the secondary part 27 of the mixing zone 23 there is an impingement zone 30; downstream of this impingement zone 30 temperatures have become so low that the particles in the product gas have lost their stickiness, so that they will not stick to the wall of the cooling section 11. Moreover, the temperature of the particles in the mixture of product gas and cooling gas in the recirculation zone 24 will be such that the particles have lost their stickiness, so that they will not stick to the wall of the cooling section 11.
The mixture of product gas and cooling gas in the recirculation zone 24 will act as an intermediate layer separating the wall of the cooling section 11 from the sticky particles in the mixing zone 23.
Downstream of the impingement zone 30 the mixture of product gas and cooling gas is removed from the cooling section 11 by passing the mixture through a conduit (not shown) to a plant (not shown) for further processing of the product gas.
The above-described apparatus can be used for cooling product gas leaving a gasification reactor wherein for example carbonaceous material is partially oxidized.
It will be appreciated that the apparatus according to the invention can also be used for cooling product gas leaving a gasification reactor in which fluid and/or gaseous hydrocarbons are partially oxidized.
If the gasification process is carried out at elevated pressures, the apparatus according to the invention will be housed in a pressure vessel (not shown).
In order to increase, during normal operation, the length of the cooling path, which extends between the circumferential outlet opening of the frusto-conical cooling gas conduit and the impingement zone, the invention further provides an apparatus comprising a tubular cooling section 36 (see Fig. 2) of which the cross-sectional area of its passage is larger than the cross-sectional area of the passage of the tubular inlet conduit 37, and a transition section 38 interconnecting the inlet conduit 37 and the cooling section 36, which transition section may be flat, or widening in the direction in which, during normal operation, product gas is passed through the apparatus.
The apparatus further comprises a first frusto-conical cooling gas conduit 41 of which the circumferential outlet opening 42 is located in the inlet conduit 37 near the transition section 38. The frusto-conical cooling gas conduit 41 is connected to an annular conduit 45 having an inlet conduit 46.
In order further to increase the length of the cooling path the apparatus also comprises a secondary frusto-conical cooling gas conduit 48 which has a circumferential outlet opening 49 and which is connected to an annular conduit 50 having an inlet conduit 51.
The frusto-conical cooling gas conduits 41 and 48 taper in upward direction, in which direction product gas is passed through the apparatus during normal operation.
During normal operation of the apparatus hot product gas is supplied to the inlet conduit 37 and is passed through the cooling section 36 in upward direction (indicated with arrow 55). Furthermore, cooling gas is supplied to the inlet conduits 46 and 51, which gas leaves the circumferential outlet openings 42 and 49 in the form of a first and a second frusto-conical annular jet, indicated with reference numerals 56 and 57, respectively.
The first frusto-conical annular jet 56 forces the hot product gas to pass through a first mixing zone 58 which has a converging and a diverging part and is surrounded by an annular recirculation zone 59, and the second frusto-conical annular jet 57 forces the mixture of product and cooling gas to pass through a second mixing zone 60 which has a converging and a diverging part and is surrounded by an annular recirculation zone 61.
At the downstream end of the second mixing zone 60 temperatures are such that the particles have lost their stickiness, so that they will not stick to the wall of the cooling section 36, and from there the mixture of gases is passed to a plant (not shown) for further processing of the product gas.
The internal diamter of the cooling section may be in the range of from 1.5 to 3 times the internal diameter of the inlet conduit.
The apparatus as described with reference to Fig. 1, wherein the internal diameter of the cooling section 11 equals the internal diameter of the inlet conduit 12, can also be provided with a secondary frusto-conical cooling gas conduit (not shown) in order to increase the length of the cooling path.
In order to improve its operating flexibility the apparatus according to the invention can be provided with more than two frusto-conical cooling gas conduits of which the circumferential outlet openings open into the apparatus, and of which the inlets can be connected to a supply of cooling gas.
In order to prevent that, during normal operation, hot particles flowing through the mixing zone touch the wall of the cooling section between two successive annular outlet openings, the distance between the openings should be in the range of from 1 to 4 times the internal diameter of the cooling section.
In an alternative embodiment of the invention the cross-section of the cooling section and of the inlet conduit may be rectangular or square.
In order to increase the residence time of the particles in the mixing zone and to obtain good mixing, the velocity with which the cooling gas is injected into the flow of product gas should be in the range of from 5 m/s to 100 m/s, more in particular in the range of from 20 m/s to 60 m/s.
In order to prevent backflow of volumes of relatively dense cold gas, the velocity with which the hot product gas enters the apparatus should be greater than 1 m/s.
A suitable thickness of a frusto-conical cooling gas conduit is in the range of from 0.5 mm to 10 mm. The apex angle 63 (see Fig.
1) of the frusto-conical cooling gas conduit 13, also referred to as angle of injection, can be in the range of from 0" to 90 . In order to reduce the risk of backflow of the frustoconical annular jet of cooling gas, to improve mixing in the mixing zone, and to have an optimum length of the cooling path, the apex angle 63 of the frusto-conical cooling gas conduit 1 3 should be in the range of from 20 to 70 .
In order to quantify mixing, a dimensionless ratio of momentum flow is introduced, this ratio of momentum flow is defined as the momentum flow of the quench gas, which is the mass flow (in kg/s) of cooling gas multi plied by the velocity with which the cooling gas is injected (in m/s), divided by the momentum flow of the product gas, which is the mass flow (in kg/s) of product gas multiplied by the velocity with which the product gas enters the apparatus. In order to obtain good mixing, the momentum flow is preferably greater than 1, and more preferably greater than 5.
