Carbon dioxide recovery

Before starting, the following preparations should be done first: 1) Check whether the unit has the starting conditions (including the reason of last stop and the condition of overhaul; check whether there are obstacles around the unit; whether the starting tools, listening needles, recording tables and so on are ready); 2) Check whether the motor, electric, instrument and lighting signal are normal, especially whether the accident chain system can act correctly (including water break, low oil pressure, axial displacement, etc.); 3) oil supply lubrication system is normal (fuel tank oil level, fuel tank bottom whether the water, auxiliary oil pump and oil circuit normal); 4) conditions of cooling system and cooling water (including whether the cooler valve is flexible, water supply pressure and water volume, etc.); 5) whether various valves are flexible and easy to use, and whether they can be closed or opened as required; 6) turn the wheel before starting, check whether the rotatin...

With the development trend of large-scale air separation plant, the column support of its matching cold box equipment tends to be large-scale. The traditional support structure has complex structure and poor bearing capacity. Through the use of finite element analysis software, DEAR air separation carries out finite element analysis and optimization on the commonly used experienced column of air separation plant, so as to improve the bearing capacity of support and reduce the processing difficulty, to reach the purpose of saving material cost.
