(2)  The scope of supply of process equipment is as follows: 1 screw compressors, 1 air pre-cooling unit, 1 molecular sieve purification system (including molecular sieve and alumina), 1 fractionation tower system (including pearlescent sand), 2 sets Complete supply of expander system, 1 oxygen booster, 1 sets of filling platoons and instrument control system, electrical system, spare parts and special tools used in supporting the above process equipment; see "Appendix 5 Process Equipment and Instrument Electricity" for details Scope of supply".

(3)    The installation materials supplied by the seller within the boundary of the air separation plant include: process piping, cryogenic liquid piping from cold box to cryogenic storage tank, steel structure pipe gallery and supports, steel structure equipment and valve maintenance platform, Cable tray, power cable, instrument cable, instrument root valve, instrument sampling pipe (stainless steel), anti-corrosion and thermal insulation materials, cutting gas, solder and other auxiliary materials required for installation work.

(4)   The installation work in the boundary area of the air separation plant includes the following: the installation of the equipment mentioned in serial number (3), the installation of ancillary instruments and electrical appliances, the installation of process pipes, steel structure pipe gallery and brackets, steel structure equipment and valve maintenance platform Installation, installation of power cables and instrument cables, installation of cable trays, anti-corrosion and heat preservation work, filling work of molecular sieve purification system packing, filling work of pearl sand, the insulation material in the cold box, linkage test work, official start-up work, flaw detection, Also includes the installation tools required for the above installation work.

(5)   Junction point: the junction point of high and low voltage cables is bounded by the inlet end of the high and low voltage cabinet of the seller; the circulating water is connected by the buyer to 1 meter outside the boundary of the air separation unit; the junction point of the product liquid is at the liquid nitrogen storage tank; nitrogen gas It is the interface of the buffer tank before the out-of-bounds area;

(6)   Performance assessment, document delivery, technical service and after-sales service related to the air separation plant.

(7)  Assist the buyer to complete other work related to the air separation plant.

1.2.  The buyer undertakes the scope of responsibility within the boundaries of the air separation plant:

(1)   Responsible for the preliminary survey and detailed survey of the land within the boundary of the air separation plant, as well as the three connections and one leveling work within the boundary.

(2)    Responsible for the civil works in the boundary area of the air separation plant (mainly

greening work, central control room, power distribution room, pipe trench and cable trench), compressor workshop and Driving in the pump room, electrical professional lightning protection and anti-static, factory lighting, equipment lighting and telecommunications, structure, water supply and drainage, inspection and testing, security monitoring, HVAC, fire engineering design, materials, and construction.

(3)    Water, electricity, pressure test gas and mechanical materials for the commissioning and start-up of the air separation plant.

The production process of this air separation unit is a domestic advanced process, and the main equipment is imported or domestic advanced.

The device has many advantages such as high safety, reliable operation, strong operability and low energy consumption.

2.   Basic conditions of device design

(subject to the parameters provided by the buyer)

3.   Main technical parameters of the device

3.1  Output and purity

3.1.1  Main production A

*Remark�?/span>

1.    To make out product by varying the working condition.

2.    The pressure of the liquid product is calculated based on the 0 elevation of the cold box. Nm³

/h refers to the state of 0°C and 760mmHg, and the pressure is gauge pressure unless otherwise specified.

3.    The standard output to be 100m3/h, while it is adjustable to switch at range of 50m3 to 105m3 so as to save power consumption when you need less output.

5.  Utilities consumption
