NOVELTY - Recycling tert. butanol in the production of ammonia involves using rectifying towers, rectifying and recovering the reaction solution from the reactor of ammonia and tertiary tert. butanol; setting the rectifying tower operation pressure of the former-effect rectifying tower and the front-effect gas-phase condensing heat energy, the push-up and a partially condensed liquid by pumping into the rectification tower to reflux, and the rest condensed liquid out rectifying system, a non-condensable gas of the cooling system to be sent into the compression system compressed out system.    USE - For recycling tert. butanol in ammonia production (claimed).    ADVANTAGE - The method reduces steam and cooling water consumption, use complete the energy, reduces the device running cost, and processes large amount of the tert. butanol.    DETAILED DESCRIPTION - Recycling tert. butanol in the production of ammonia involves using rectifying towers combined into a rectifying system, and configuring the corresponding a reboiler, a cooling system, a return flow system and compression system, a two-effect or multiple-effect rectifying and recovering the reaction solution from the reactor of ammonia and tert. butanol, setting the rectifying tower operation pressure of the former-effect rectifying tower and the front-effect gas-phase condensing heat energy, where the operation pressure of former-effect is 0.08-0.6 MPa (absolute pressure), the operation pressure of the last effect is 0.001-0.1 MPa, where the former-effect temperature is 60-140 degrees C, the tower top before the former-effect tower top temperature is higher than the back one effect tower kettle temperature is 10-40 degrees C, the tower top gas phase by condensation cooling system, controls the discharging temperature is 10-80 degrees C, the condensate return-flow system, the push-up and a partially condensed liquid by pumping into the rectification tower to reflux, and the rest condensed liquid out rectifying system, a non-condensable gas of the cooling system to be sent into the compression system compressed out system.
