For the Designing of 100TPD oxygen plant requires separate designing of distillation unit and condenser. Oxygen gas is commonly used in steel plant, medical field, blast furnace etc. This process is convenient because the raw material is available at no cost and in limitless amounts. Oxygen plant consists of number of unit operation like compressors, heat exchanger, distillation column, expansion turbine etc. The final objective is to separate oxygen from air at desired purity requiring minimum

... cost. The purity of oxygen over 99.5% is required for welding, cutting and medical application. In order to minimize the costs, heat integration is used throughout the process. A column st is designed to maintain product purity and reject disturbances. The effect of product quantities and purities on the selection of process cycle is discussed and general design guidelines are given. Another methods such as membrane (up to about 40% oxygen), pressure swing adsorption (PSA) and vacuum pressure swing adsorption (85-95% oxygen) are commercially used to separate oxygen from ordinary air. High purity oxygen requires cryogenic distillation. The primary hazards in oxygen plant are fire hazards which are mainly focused. Any industrial process that generates or uses oxygen is exposed to an elevated risk of fire. This applies in particular to oxygen plant, where the presence of oxygen obviously increases fire hazards. Mechanism such as friction, Mechanical impact and organic material non-compatible with oxygen can quickly spark a fire inside valves, for instance. In the presence of oxygen, any flammable material once ignited will readily burn. The important ant requirements for safely handling oxygen plant within air separation facility.
