Abstract
The present invention proposes a kind of processing method of rationally utilizing waste heat in the conversion gas production process.The present invention adopts heating type chemical classes heat pump, and as absorption heat pump, the low temperature exhaust heat that conversion gas is contained converts the heat energy of higher potential temperature to, in order to hot water, desaturation raw material semi-water gas to take place.Having changed the sort of consumption process steam of traditional technology or need be provided the method for hot water by the external world.Improved the energy utilization efficiency of process.
Description
The present invention propose one plant the processing method rationally utilize conversion gas production process waste heat.Be applicable to the energy-saving design or the transformation of the process industrial of production of conversion gas or similar operating condition.
Accompanying drawing 2 is that the energy of traditional conversion gas production process utilizes the situation synoptic diagram.
In this production process, need the saturated laggard line translation reaction of pressurized hot water through the semi-water gas of overdraft by extraneous adition process steam or about 150 ℃, reaction product conversion gas is sent after waste heat recovery.And the method for giving heat outside the battery limit (BL) is adopted in the recovery of waste heat usually.
Accompanying drawing 3 is the traditional exhaust heat recovering method synoptic diagram of conversion gas production process.
As shown in Figure 3: 230 ℃ conversion gas the presaturation process of semi-water gas and outside the battery limit (BL) logistics give that (part of waste heat is provided) is cooled to about 110 ℃ in the process of heat outside the battery limit (BL), through cold soft water warm cold soft water is heated to 82 ℃ by 23 ℃ then, delivers to the condensation cooling tower with the temperature about 80 ℃.Can find, in above-mentioned traditional conversion gas production process, need import the process steam or the pressurized hot water of higher enthalpy grade on the one hand, when waste heat recovery, provide suitable heat energy to the external world again on the other hand by the external world.A large amount of heat of condensation of containing by water vapour in the saturated conversion gas, remain to be utilized method more effectively and reasonably to be reclaimed.
Purpose of the present invention: be the conversion gas production process waste heat that reduces to external world's output, adopt heat pump techniques, convert the contained low grade residual heat of conversion gas to transformationreation and produce required heat energy, so that reduce or needn't import this part energy by the external world than higher-grade.
Based on above-mentioned purpose, essential implementation of the present invention is:
1) in conversion gas production process, adopts heating type chemical classes heat pump, with the low grade heat energy of conversion gas, as 110 ℃-85 ℃ producer and the vaporizers of introducing heat pump as the thermal source of heat pump.
2) make cold soft water required in the conversion gas production process, by the condenser of heat pump, the part of heat pump consumption of calorie is discharged heat pump, leave heat pump after cold soft water is preheated, it is used for production process to enter another soft water preheater heating back.
3) another part of heat pump consumption of calorie is taken heat pump out of by the heat-eliminating medium by heat pump condenser.
4) the low temperature shift gas that was utilized of being drawn by evaporator with heat pump heats soft water once more by soft water preheater.
5) with required pressurized hot water in the conversion gas production process,, be warming up to, enter well heater then, be heated to before the semi-water gas saturator temperature required with the conversion gas of higher temperature in the production process near use temperature by the heat pump resorber.
The operating mode that provides with accompanying drawing is an example below, and is open in detail to the present invention.
Accompanying drawing 1 is an application example schematic flow sheet of the present invention.
As shown in Figure 1: by producer 1, condenser 2a, 2b, vaporizer 3 and resorber 4 are formed heat pump, conversion gas about 110 ℃-85 ℃ is introduced heat pump as thermal source, when flowing through producer and vaporizer, conversion gas is reduced to about 86 ℃ by 110 ℃, condensation cooling heat is offered heat pump, this heat part is discharged from condenser as the consumption that drives heat pump, another part is heated to the hot soft water through resorber about 133 ℃ by 120 ℃ as the benefit of system, enters the superheater 7 of production process.The part of heat pump institute consumption of calorie is taken heat pump with cooling circulating water out of from condenser 2a.Another part is taken heat pump out of by the condenser 2b cold soft water preheating (rising to 38 ℃ by 23 ℃) just that production process is required.Just soft water preheating is delivered to another soft water preheater 5, has so not only reasonably utilized waste heat, and has alleviated the condensation load of recirculated water.The low temperature shift gas that was utilized from vaporizer 3 comes out rises to 38 ℃ of left and right sides soft water that condenser 2b comes about 82 ℃ by soft water preheater 5, enters production process, delivers to cooling tower and itself reduce to about 58 ℃.About 133 ℃ hot soft water by heat pump produces when flowing through superheater 7, is hanged down and is delivered to saturator after the about 230 ℃ conversion gas that becomes stove is heated to 147 ℃, makes the usefulness of saturated semi-water gas.
The present invention makes conversion process waste heat obtain effective utilization owing to adopted the heat pump technology flow process of reasonably arranging production, and obtains obvious effect:
A, hardly must be by importing the required process steam of transformationreation or pressurized hot water outside the conversion section battery limit (BL).
B, the conversion gas product of delivering to condensing cooling tower have reduced about 22 ℃ than traditional handicraft, have namely increased the waste heat recovery amount of production process.
No matter c, flow process of the present invention be the preheating at cold soft water, or in the generating process of the hot soft water of saturator, heat transfer temperature difference has all suitably reduced, and this thermodynamics degree of perfection that means new flow process is higher, and energy has not only more effectively obtained utilization in quantity but also on quality.
