2.Process Description and performance requirements

2.1流程描述

2.1Process Description

本方案装置所需要的空气由用户提供，通过一套自动控制系统，根据氮气的产量，从空气管网中，自动控制进入装置的压缩空气量。用户提供压缩空气含油量小于5ppm。

The program means the air required by the user, through an automatic control system, automatic control based on nitrogen production from air pipe network access device in the amount of compressed air.The oil content of compressed airsupplied by the users should be less than 5ppm

压缩空气进入预冷系统冷被冷干机冷却到5~8℃，露点温度5~8摄氏度，之后复热到25~32℃去纯化系统。这个系统由空气冷干机和三级油过滤器等设备组成，在除去空气中水分的同时，除去空气中的油雾，使其含油量降至满足空分设备的要求。

Compressed air into the pre-cooling system is colded and drought to 5 ~ 8 ℃,

dew point temperature 5 ~ 8 ℃ bycold and dry machines, then re-heated to 25 ~ 32 ℃ to purification system. The system consists of cold and dry air and tertiary oil filters and other equipment in the removal of moisture in the air while removing oil mist in the air, so that the oil content down to meet the requirements of an air separation plant.

纯化系统中的吸附器由两台立式容器组成；两台吸附器采用外绝热双层床结构，当一台运行时，另一台则由来自冷箱中的污氮通过加热器加热后进行再生。

Purification System adsorber vessel by two vertical composition; two adsorber with external insulation bunk bed structure, when one runs, another from the cold tank by nitrogen pollution through the heater heating regeneration.

分子筛纯化器采用双层床结构，吸附器切换再生采用恒流量控制方式，改善主塔工况的稳定性。分子筛吸附系统布置紧凑，吸附剂和切换阀门使用寿命长，系统切换损失小，有防止分子筛吹翻措施和可能吹翻的处理措施。

MS purification uses a bunk bed structure, switching adsorber regeneration using constant flow control, improve the stability of the main tower operating conditions. Molecular sieve adsorption system compact layout, adsorbents and switching valves long life, the system switches loss, molecular sieves blown measures and possible measures to prevent blown processing.

净化后的空气分为两部分，一部分作为仪表空气和装置膨胀机加温气、一部分进入板式换热器冷却，接近液化点后进入下塔参与精馏，下塔精馏后顶部得到满足纯度的氮气，氮气进入主冷氮侧冷凝后成为液氮，一部分液氮回流下塔顶部做回流液，一部分作为液氮产品。

Purified air is divided into two parts, as part of the expansion device and instrument air warming gas, into a part of the plate heat exchanger cooled, liquefied close involvement rectification column into the next point after the top of the next column distillation are met purity nitrogen nitrogen main cold liquid nitrogen become condensed nitrogen side.Part of a stream of liquid nitrogen will be top of the column as reflux, as part of the liquid nitrogen product.

从主冷凝蒸发器中来的污氮气经过过冷器、主换热器复热至一定温度后膨胀

制冷，然后去主换热器复热至常温，部分作为分子筛再生气进入纯化系统，其余到放空。

From the main condenser to the evaporator nitrogen pollution through subcooler, main heat exchanger after the re-expansion refrigeration heat to a certain temperature, and then to re-heat the main heat exchanger to ambient temperature, as part of the regeneration gas into the molecular sieve purification system, to rest vented. 在精馏塔顶部，纯氮气作为合格的产品氮气经主换热器复热后从冷箱引出。

At the top of the rectification column, after the pure nitrogen nitrogen as qualified products through the main heat exchanger complex extracted from the cold box
