The start-up and operation of liquid air separation plants requires the operator to be familiar with the performance and operation of the systems, machines and equipment in the liquid air separation plants, to be familiar with the process flow diagram of the liquid air separation plants, and to master the operation rules and operating characteristics of the liquid air separation plants. In order to ensure the purity of the product, the operator must be able to improve the quality of the product and reduce energy consumption and costs. The staff must consider all systems in the liquid air separation plants as a whole.
The operation of liquid air separation plants consists of two parts.
(1) the commissioning of liquid air separation plants, i.e. the test, adjustment, blowing, etc., prior to the operation of the complete set of equipment linkage, the test is to ensure that each ministry, each system and its interconnection between the correct.
(2) The start-up of liquid air separation plants and put into normal operation. The commissioning of liquid air separation plants is after the installation or overhaul of liquid air separation plants, in the formal production before, the individual parts of the machine, equipment and complete sets of liquid air separation plants for a comprehensive pressure test, leak detection, adjustment, blowing and low-temperature bare cold test, etc.. The inspection of the installation or overhaul of air separation equipment includes checking the sealing performance and compensation performance after cold deformation at low temperatures, possible defects and installation defects in equipment and piping flow paths.
In order to ensure the safe, reliable, stable and high-quality continuous operation of the air separation equipment, Dear has developed detailed operating instructions for the complete set of small air separation units,large air separation units and liquid air separation plants.
