Description

technical field [0001] The invention relates to the field of raw gas exploitation and treatment, in particular to a highly reliable heating regeneration natural gas molecular sieve dehydration skid. Background technique [0002] At present, there are mainly methods such as solvent absorption, solid adsorption, membrane separation and ultrasonic vortex tube for the deacidification and dehydration of natural gas. Among them, the triethylene glycol solvent absorption method is currently the most widely used process in the gas field gathering and purification process in my country. Although TEG dehydration Stable performance and large water absorption capacity, but the solvent is easily lost and polluted during the dehydration process, and needs to be replenished and cleaned in time, and the regeneration energy consumption is relatively large.

[0002] At present, there are mainly methods such as solvent absorption, solid adsorption, membrane separation and ultrasonic vortex tube for the deacidification and dehydration of natural gas. Among them, the triethylene glycol solvent absorption method is currently the most widely used process in the gas field gathering and purification process in my country. Although TEG dehydration Stable performance and large water absorption capacity, but the solvent is easily lost and polluted during the dehydration process, and needs to be replenished and cleaned in time, and the regeneration energy consumption is relatively large. Therefore, it is only suitable for gas field mining with large production and stable working conditions. For natural gas wells that are far away from the gas gathering station, have low temperature and harsh environment, the viscosity and energy consumption ratio of TEG will decrease, and the overall equipment price and maintenance cost will be higher. In contrast, the solid adsorption method is more effective and efficient. Cost advantage, through the contact between the natural gas flow and the porous solid particles, the water molecules in the fluid are adsorbed by the surface of the inner pores of the solid, and the adsorbent after absorbing water is heated and pressurized to change its equilibrium direction and remove the water

[0003] Most of the high-reliability heating and regenerative natural gas molecular sieve dehydration skids in the market have poor filtering effect on shale gas and cannot be recycled. Therefore, we propose a high-reliability heating and regeneration natural gas molecular sieve dehydration skid
