Chapter 3 Selection of Process Equipment
Article 3.0.1 The design capacity of the oxygen station shall be determined based on the oxygen usage characteristics of the user after comparing the schemes. It can be determined based on the user's average hourly consumption during the day and night or the average hourly consumption during the work shift after comparing the technical and economic schemes. The design capacity of the oxygen station must take into account the impact of the local altitude. Article 3.0.2 The model and number of air separation equipment and the selection of spare units of oxygen stations shall be determined based on the user's requirements for air separation products and after comparison of technical and economic plans, and shall meet the following requirements:
1. The number of air separation equipment should be determined based on the principle of large capacity, few units and unified model;
2. The compressor for air separation gaseous products shall be selected based on the user's requirements for the purchase, storage and transportation of air separation gaseous products;
3. Oxygen stations may not be equipped with spare air separation equipment. When the interruption of gas supply by users will cause great losses, the standby of rotary units such as air compressors and oxygen compressors in the air separation equipment should be considered, and other methods can also be used to adjust the gas supply. Article 3.0.3 The selection of the capacity of the air separation gas product storage tank shall meet the following requirements:
1. To adjust the imbalance between gas production and compressed gas, a wet storage tank or gas storage bag should be used, and its effective volume should be determined according to the imbalance between gas production and compressed gas.
2. To adjust the imbalance between gas consumption and gas production, a medium-pressure or high-pressure storage tank should be used, and its effective volume should be determined according to the imbalance between gas consumption and gas production, as well as the working conditions of gas purchase and transmission.
Article 3.0.4 The number of various gas cylinders can be determined according to three times the number of gas cylinders used by the user at night, but does not include spare gas storage cylinders. Engineering Construction Standard Full Text Information System8X10Pa).
Liquid oxygen storage tanks are calculated based on 1m3 of liquid oxygen converted to 800m2 of standard state gaseous oxygen, and the provisions of the corresponding storage capacity of these oxygen tanks in this table shall apply.
③The distance between oxygen storage tanks, inert gas storage tanks, outdoor process equipment and their oxygen production plant can be determined according to the process layout requirements.
③The fire protection distance between oxygen storage tanks should not be less than the radius of the adjacent larger tank. The fire protection distance between oxygen storage tanks and flammable gas storage tanks should not be less than the diameter of the adjacent larger tank. ③The fire protection distance between oxygen storage tanks with a volume not exceeding 50m2 and the affiliated use plant is not limited. The fire protection distance between liquid oxygen storage tanks with a volume not exceeding 3m2 and the affiliated use building can be reduced to 10m. ①There should be no combustibles and asphalt pavement within 5m around the liquid oxygen storage tank. ① The minimum fire separation distance between the air separation tower or inert gas storage tank arranged outdoors in the oxygen station and other types of buildings shall be determined according to the Class B production buildings (air separation tower) or Class E production buildings (inert gas storage tank) with the first or second level of fire resistance.
The minimum fire separation distance between Class B production buildings with the first or second level of fire resistance, such as oxygen stations, and other Class A production buildings shall be 2m higher than the distance specified in this table for other types of production buildings.
The minimum fire separation distance between wet oxygen storage tanks and flammable liquid storage tanks and flammable material yards shall comply with the distance specified in this table for civil buildings and places with open flames or sparks. Article 2.0.4 Oxygen production station, oxygen filling station or oxygen compression station, liquid oxygen gasification station should be arranged as independent buildings, but can be built adjacent to other workshops with fire resistance rating not lower than their own, except for production workshops with fire hazard of "A" and "B", and foundry workshops, forging workshops, heat treatment workshops and other open fire workshops. The adjacent walls should be fire walls without doors, windows and holes.
