specific Embodiment approach 1

[0020] Specific embodiment one: present embodiment is a kind of process method that uses gas pressurization device to pressurize gas, is to finish according to the following steps:

[0021] The temperature in the water gas tank 1 is 40°C and the pressure is 150mmH 2 The water gas of O is passed into the first separator 2 to remove the liquid, and the water gas after the first separator 2 removes the liquid enters the first inlet port 3-1-1 of the first section of the gas pressurized compressor into the first section of the gas pressurized compressor Pressurize in 3-1, the pressure of water gas in the first stage 3-1 of the gas pressurizing compressor rises to 0.220MPa-0.230MPa, and the temperature rises to 122°C-124°C;

[0022] The water gas with a pressure of 0.220MPa-0.230MPa and a temperature of 122°C-124°C comes out of the first outlet port 3-1-3 of the first stage of the gas pressurized compressor and enters the first gas cooler 4. 4 to 38°C to 42°C, then enter the secon...

specific Embodiment approach 2

[0032]Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: the gas pressurization device is provided with an anti-surge circuit; 4 is drawn out, and flows back into the first section 3-1 of the gas pressurizing compressor through the regulating valve 13 and the second inlet port 3-1-2 of the first section of the gas pressurizing compressor to form an anti-surge circuit. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0033] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the gas pressurization device is provided with a vent pipe; the vent pipe is from the second outlet end of the fourth separator 9-3 lead, through the automatic switching valve 12 to vent to the torch 11. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The present invention discloses a process method for using a coal gas pressurization device for pressurizing coal gas, relates to a process for pressurizing coal gas, and aims to solve the problems that a coal gas pressurization device used in the process for synthesis of methanol from coal gas is poor in pressurizing effect, poor in cooling effect and does not apply to large gas flow working conditions. The process method is as follows: water coal gas in a water coal gas tank is treated by a first separator, a coal gas pressurizing compressor I section, a first gas cooler, a second separator, a coal gas pressurizing compressor II section, a second gas cooler, a third separator, a coal gas pressurizing compressor III section, a third gas cooler and a fourth separator, and then enters a temperature swing adsorption device to complete the process method for using the coal gas pressurization device for pressurizing the coal gas. The process method for using the coal gas pressurization device for pressurizing the coal gas can be obtained.

Description

technical field [0001] The invention relates to a process method of pressurized coal gas. Background technique [0002] In the existing process of using coal gas to synthesize methanol, the water gas needs to be pressurized; since the water gas has been compressed, its temperature has also increased. The heated compressed gas is cooled between the compression stages by means of an intercooler in which the heated compressed gas is cooled by indirect heat exchange with a coolant. [0003] The existing gas pressurization device and process used in the process of synthesizing methanol from coal gas make the pressurization effect of the gas poor, the cooling effect is poor, and it is not suitable for working conditions with large gas flow. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the gas pressurizing device used in the process of using coal gas to synthesize methanol has poor pressurizing effect, poor cooling effect a...
