Process piping specifications for the ammonia synthesis tower unit
We are a DN1200 ammonia tower; the make-up gas pipeline is φ159X28, the circulating cold gas pipeline is φ219X35, the circulating hot gas pipeline is φ273X40, the cold shock line is φ159X28, and the tower accessory line is φ127X21. The principle is to ensure that the gas flow velocity within the pipe does not exceed 10 meters per second, and attention must be paid to making temperature corrections.
We are a DN1000 ammonia tower; the supply gas pipeline is φ127X21, the circulating cold gas pipeline is φ180X30, the circulating hot gas pipeline is also φ180X30, the cold shock line is φ102X17, and the tower attachment pipeline is φ127X21.
We are a DN2000 ammonia tower; the supply pipelines have a diameter of φ219X35, the circulation pipelines have a diameter of φ273X40, the tower connection pipelines have a diameter of φ159X28, and there are three cold shock pipelines with a diameter of φ159X28 each. 4 cyclones (12 Nm3/m each), with 3 in operation and 1 as backup; the space velocity is approximately 9000, and the gas make-up volume at full load is 67,000 Nm3/h.
Our ammonia tower is DN1500; the make-up gas pipeline is DN125, the circulation gas pipeline is DN150, the tower branch pipelines are DN125, and the cold shock pipeline is DN125.
