Double tower that is suitable for transportation of sled piece absorbs palingenetic natural gas deacidification equipment of double tower, tower cauldron of A absorption tower (14) bottom and the tower cauldron of B absorption tower (15) bottom are mutual independence intercalary band baffle and be linked to be a whole, and first reboiler (25) and second reboiler (26) are installed respectively to tower cauldron of A regenerator column (16) bottom and the tower cauldron of B regenerator column (17) bottom, and these two tower cauldrons are linked to be whole and the middle baffle mutual independence again that installs moreover, utilize A regenerator column (16) and B regenerator column (17) pressure differential to provide regeneration amine liquid for B regenerator column (17) to the economization design of relay pump, the integration sets up and has all obviously reduced the tower height degree biabsorption tower with two regeneration tata cauldrons, effectively reduces sled piece quantity and moves equipment quantity, for independent double tower structure, saves a sled piece inner space, and reduces installation, transportation and the quick travel that is favorable to very much deacidification sled piece after high, also can install on simple and easy ground.
