Description

SPECIFICATION Integrated gasification-methanol synthesiscombined cycle systems This invention relates to Integrated Coal Gasification Combined Cycle Systems for electric power generation and in particular to the inclusion of a methanol synthesis means to enable the operation of the coal gasification means at steady-state and/or full load capacity.
An integrated coal gasification-combined cycle (IGCC) power plant holds great promise for the generation of electric power from coal in an increasingly efficient, low cost and environmentally sound manner.
With reference to Fig. 1, an integrated coal gasification-combined cycle (IGC:C) power plant 10 combines and integrates a coal gasification plant 1 2 with both gas turbine 14 and steam turbine 1 6 driven electric power generators in a combined cycle power plant 18. Oxygen is produced in an oxygen plant 20 from air. Coal is received and prepared for processing in a Coal Handling and Slurry Preparation Plant 22. The prepared coal reacts with oxygen and is gasified in a Gasifier 24 at high temperature to produce a fuel gas, or a synthetic gas.The sensible heat is removed from the fuel gas in a Syngas Cooler 26 and used to heat boiler feed water for steam making for operating the Steam Turbine Generator 1 6. Particles of combustion products which escape from the Gasifier 24 with the combustible fuel gas may be removed by suitable processing in a cleaning unit such as a Water Scrubber 28. The particles which are removed in the Scrubber 28 contain unreacted hydrocarbons and are reintroduced into the Gasifier 24.
The combustible fuel gas from the Scrubber 28 is introduced into a Fuel Gas Cooling and Reheater 30 whereby heat is extracted from the gas and utilized to reheat clean fuel gas from Sulfur Removal Means 32. The cooled combustible fuel gas is introduced into the Sulfur Removal Means 32 and the sulfur, which originated from the coal and later was converted to hydrogen sulfide in the gasifier, is removed from fuel gas. Any of several commercially available sulfur removal processes and units may be employed in order to reduce the hydrogen sulfide content in the combustible fuel gas to be combusted in the Gas Turbine Generator 1 4. The hydrogen sulfide removed from the gas by processing in the Sulfur Removal Means 32 may be readily converted to elemental sulfur in Sulfur Recovery Means 34 by available process and apparatus well known to those skilled in the art.
The clean combustible fuel gas from the Sulfur Removal Means 32 is reheated, as required, to the elevated temperature necessary for introduction into the Gas Turbine Generator 14 in Reheater 30 and/or Clean Gas Heater 36. In the Generator 14, the gas is combusted to produce hot gases to propel the Generator 14 and generate electricity. Hot exhaust gas from the Gas Turbine Generator 14 is directed to a Heat Recovery Steam Generator 38 where, by heat exchange means, steam is generated, which, drives the Steam Turbine of the Generator 1 6 to make electricity in the same manner as a steam turbine in a conventional plant. Steam bled from the Steam Turbine Generator 1 6 or electricity from either or both Generators 1 4 and 1 6 is utilized in operating the Oxygen Plant 20.Exhaust gas from the Heat Recovery Steam Generator is exhausted to the atmosphere via Stack 40.
When the demand for electricity is increased or decreased, the electrical output of the Combined Cycle Plant 1 8 increases or decreases directly with the demand for electricity. When the output of the Combined Cycle Plant 1 8 is increased to meet an increased demand for electricity, the operation of the Coal Gasification Plant 1 2 is increased to produce the necessary combustible fuel gas for the increase demand of the Turbines 14 and 16.When the Combined Cycle Plant 18 returns to its normal, lower output of electrical energy, the operation of the Coal Gasification Plant 1 2 is decreased to produce only that amount of combustible fuel gas necessary to meet the lower demands of the Plant 1 8. The operation of the Coal Gasification Plant 1 2 is, therefore, a direct function of the operating cycle of the Combined Cycle Plant 1 8.
Although the Integrated Coal Gasification Combined Cycle Plant 10 of the prior art is practical and more efficient than some prior art power generation systems, there are still three basic problems associated with the operation of the Plant 10. One problem is that the Plant 10 should be capable of being operated in a manner which permits the Plant 10 to have a quick response to power low changes such, for example, as the normal daily oscillation in power requirements. The second problem is that the Plant 10 does not always operate at or near maximum capacity. The Plant 10 is intended to operate only at from 55 percent to 75 percent of plant capacity as it serves as a base load for the daily electrical requirements of the service area. The third problem is the Plant 10 always has a requirement for fuels to provide peak load capability.
The Coal Gasification Plant 12, in view of the above problems associated therewith, may not be able to load changes satisfactorily, particularly the peak load changes. The length of time required for the Plant 1 0 to reach a new steady state operation is not satisfactory.
Heating values of fuel gas produced by the Gasifier 24 will be different during and/or after load response transition stages. Should the operation of the Oxygen Plant 20 fluctu ate directly with the operation of the Plant 10, the purity of the oxygen produced may be affected.
In accordance with the teachings of this invention there is provided an improved Integrated Coal Gasification-Combined Cycle (lGCC) power plant. The improvement is the inclusion of Methanol Synthesis Plant which enables the coal gasification plant to operate at a steady state instead of following the fluctuations in the Combined Cycle Power Plant as it responds to the gas produced by the coal gasification plant and not required by the Combined Cycle Power Plant is synthesized to methanol and stored as a liquid.
The stored methanol can be sold or used as fuel. As a fuel, liquid methanol can be used for the initial starting up of the Combined Cycle Power Plant. The liquid methanol can also be combusted simuitaneously with clean fuel gas in a Gas Turbine Generator to maintain or increase the electrical generating capacity of the generator. Additionally, the liquid methanol may be employed to operate a Peaking Power Load Plant utilized to meet peak power load demands placed on the Combine Cycle Power Plant. The Peaking Load Power Plant may include a gas turbine generator, with or without means to preheat the methanol, and a steam generator operated by steam generated by extraction of heat from the exhaust gas of the gas turbine.
The present invention will be further described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a combination block and schematic diagram of a prior art integrated coal gasification-combined cycle (IGCC) power plant.
Figure 2 is a combination block and schematic diagram of an integrated coal gasification-combined cycle (IGCC) power plant including a methanol synthesis plant.
Figure 3 is a combination block and schematic diagram of alternate means for employing stored methanol.
Referring now to Fig. 2, there is shown an improved Integrated Coal Gasification-Combined Cycle Plant 50 embodying a methanol Synthesis Plant 52. The reference numerals which are the same in both Fig. 1 and Fig. 2 denote items which are the same and which function in the same manner as previously described.
The size of the Methanol Synthesis Plant 52 is determined by several factors. One factor is the amount of load available for installing a methanol plant and associated units such as a Methanol Synthesis Unit 54 and a Methanol Distillation and Storage,Unit 56. A second factor is that the methanol plant 52 must have the capacity to process the volume of clean gas introduced. Alternately, the methanol plant 52 should have the capability to receive all the clean fuel gas produced by the Coal Gasification Plant 12, synthesize a portion of the gas to methanol in one or more passes through the Plant 52, and exhaust the remainder to the Combined Cycle Power Plant 1 8. A third factor is the amount of methanol required to be stored to be available for peaking load operation to meet demand electrical load requirements.A further factor is the economics of building and operating a specific sized plant and its associated facilities for the benefits to be derived both economically and for energy conservation.
The Coal Gasification Plant 1 2 is designed to operate at a steady state to gasify coal to produce a clean fuel gas consisting essentially of hydrogen and carbon monoxide after sulfur removal and reheating. The total quantity of clean fuel gas is sufficient to at least operate the Combined Cycle Power Plant 1 8 at its designed normal rated load and to provide sufficient gas from which methanol may be synthesized and stored for future use as an alternate fuel to assist in the meeting peak electrical demand requirements as the need arises.
The clean fuel gas flow may be divided prior to entering the Methanol Synthesis Plant 52. Sufficient gas is caused to flow through the clean gas heater 36 to operate the Combined Cycle Power Plant 18 at its normal rated operating load. The remainder of the gas is caused to flow through the Methanol Synthesis Unit 54 where methanol is synthesized from the fuel gas. Boiler feed water from the Heat Recovery Steam Generator 38 may be employed in the methanol synthesis process to produce steam. Thereafter, the synthesized methanol is introduced into the Methanol Distillation and Storage Unit 56 where the methanol is recovered by distillation and stored for future use.
Alternately, all of the clean fuel gas is introduced into the Methanol Synthesis Plant 52. The operation of the Plant 52 is continually monitored to provide a sufficient volume of clean fuel gas to meet the needs for normal operation of the Combined Cycle Power Plant 1 8. The remaining volume of gas undergoes chemical synthesis to produce methanol for storage.
When an increase in the demand electrical load is received by the Combined Cycle Plant 18, the monitoring means decreases the volume of gas available for methanol synthesis, thereby increasing the volume gas available to meet the operating needs of Plant 18. When the demand electrical load for Plant 1 8 is reduced, the monitoring means adjust the gas flow volumes to enable a greater portion of the clean fuel gas to undergo methanol synthesis. Throughout these demand load changes of the Plant 18, the Coal Gasification Plant 1 2 operates at a steady state producing the same volume of clean fuel gas continu ously throughout the demand load changes.
The stored methanol may be utilized in several ways. All or a portion of the stored methanol may be sold. Alternately, all or a portion of the stored methanol may be employed to assist in the start up of the Integrated Plant 50. Liquid methanol is combusted in the Gas Turbine Generator 14 for the initial start up of the Combined Cycle Power Plant 1 8. While the Coal Gasification Plant 1 2 is being brought on line the clean fuel gas and methanol provide a dual fuel mixture. As the quantity of clean fuel gas increases, the quantity of methanol required from storage decreases.When sufficient clean fuel gas is being produced by the Plant 1 2 to satisfy the normal operating requirement needs of the Plant 18, the supply of liquid methanol is stopped, the Methanol Synthesis Plant 52 is brought on line, and methanol is again produced for storage to meet future needs.
A further option for use of the stored methanol is to fire liquid methanol with clean fuel gas (a dual fuel combustion) in the Gas Turbine Generator 1 4 without disturbing the steady state or full load operations of the Coal Gasification Plant 1 2 and Methanol Synthesis Plant 52, when the load demand in the Combined Cycle Plant 1 8 includes both .he normal based load and the medium load. The supply of liquid methanol is stopped when the load demand in the Combined Cycle Plant 1 8 returns to the normal based load operation.
A still further alternate use for the stored methanol is to employ the methanol as a fuel in a Peaking Plant 60. The Plant 60 provides the means for generating the additional electrical power to meet the peak load demands of the Combined Cycle Power Plant 1 8 where duel fuels are combusted. One or more different electrical generating systems may be employed in the Plant 60. A first system is a Simple Cycle System 62. Liquid methanol is combusted in one or more Gas Turbine Generator 64 to generate the needed peak load electricity. The exhaust gas is caused to flow directly to the Stack 40 or to pass through the Steam Generator 38.
A second peaking electrical generating system is a Regenerative Cycle System 66 which includes one or more Gas Turbine Generator 68 and associated Fuel Preheater Unit 70.
The liquid methanol is combusted in the Generator(s) 68 to generate the peaking electrical load. The exhaust gas is caused to flow through Preheater Unit 70 to heat the liquid methanol prior to its entry into the combustion chamber of each Generator 68 after initial start up of the Generator 68. The exhaust gas from the Unit 70 is then caused to flow to the Stack 40.
A third peaking electrical generating system is a Steam Turbine and Gas turbine Combined Cycle System 72. The System 72 comprises a Gas Turbine Generator 74, a Steam Turbine Generator 76 and å Heat Recovery Steam Generator 78. Liquid methanol is combusted in the Generator 74 to generate a portion of the peaking electrical demand load required.
The exhaust gas from the Generator 74 is caused to flow through the Steam Generator 78 to produce steam to drive the Steam Turbine Generator 78 to generate the remainder of the peaking electrical demand load. The exhaust gas from the Steam Generator 78 is vented via the Stack 40.
The employment of the Methanol Synthesis Plant 52 in the improved Integrated Coal Gasification Plant-Combined Cycle Power Plant 50 enables the Coal Gasification Plant 1 2 to operate at a steady state level. Excess clean fuel gas converted to a liquid fuel, methanol, enables the Combined Cycle Power Plant 1 8 to have fast start ups, be capable of using a dual fuel system and to have rapid response to changes in medium and peak electrical demand loading.
