Description

Technical Field

[0001] This invention relates to the field of natural gas processing technology, and in particular to a device suitable for dehydrating and purifying lean glycol from natural gas containing heavy hydrocarbons. Background Technology

[0002] The natural gas flowing from the wellhead is almost entirely saturated with gaseous water, and may even carry a certain amount of liquid water. The presence of water in natural gas often has serious consequences. For example, natural gas containing CO2 and H2S can form acids in the presence of water, which can corrode pipelines and equipment. Under certain conditions, natural gas hydrates can form, which can block valves, pipelines and equipment, reduce pipeline transport capacity, and cause unnecessary power consumption. The presence of water in natural gas is very detrimental, so natural gas dehydration is essential.

[0003] Existing natural gas dehydration and lean glycol purification devices, such as the one disclosed in application number CN202411084850.4, which has a hydrogen recovery function and belongs to the field of natural gas purification technology, include: a shell, a conveying chamber at the bottom of the shell with several air inlets at the bottom of the conveying chamber, several air outlets at the top of the shell, a condensing device inside the shell, and an electrolysis device at the bottom of the condensing device; the condensing device then condenses the vapor contained in the natural gas, and the liquid droplets produced by the condensation of the vapor are fed into the electrolysis device. The natural gas is transported and then electrolyzed to produce hydrogen and oxygen, thus achieving hydrogen energy recovery. The dehydrated natural gas is then transported to the side near the outlet and finally discharged through the outlet, thereby realizing the dehydration process of natural gas purification, avoiding impurities from affecting the purity of natural gas, and thus improving the purification quality of natural gas. However, in the above technology, the condenser column has a large space, resulting in poor contact area of ​​the gas and affecting the dehydration effect of the product. Therefore, we propose a dehydration and lean glycol purification device suitable for natural gas containing heavy hydrocarbons to solve the above problems. Summary of the Invention

[0045] The working principle of this invention is as follows: When processing is required, the gas inlet valve 205 is opened, causing the first gas pump 204 to output power and drive the output end to run, so that the material is input into the bottom chamber 203 on the opposite side of the upper sleeve plate 202.

After desulfurization, the... The exhaust pipe 301 and the bridging valve 302 at the output end output the gas to the condensation chamber 303. After passing through the chiller 307, compressor pump 308, circulation pipe 309, inner ring pipe 304, and inner fins 305, the gas achieves a circulating cooling effect, allowing the gas to contact and condense. The condensed water is then input into the node chamber 402 through the second bottom section pipe 403. The dehydrated gas is output through the exhaust valve block 3010. Then, the control box 406 outputs the material, which is heated by the partition plate 407 and heating rod 408, allowing the material to pass through the first... The water is fed into the heating chamber 405 via a bottom section pipe 401, a node chamber 402, a second bottom section pipe 403, and an inlet valve block 404. After the water evaporates, it is discharged as pure liquid through a drain valve block 409 and a discharge pipe 4010. When pressure reduction is required, the hydraulic cylinder 4014 on the airlock chamber 4012 is used to output power to drive the output end to operate. This causes the control plate 4016 at one end of the coupling frame 4015 to cooperate with the airlock chamber 4012 to reduce the air pressure inside the equipment. Then, the riser pipe 4017 is used in conjunction with the condenser chamber 4019 to condense the water and feed it into the drain valve block 4020 to achieve the effect of condensed water discharge.
