空分装置原始开车时，由动力分厂为空分装置提供驱动汽轮机用的高压蒸汽和蒸

When the air separation unit was originally started, the power plant provided the air separation unit with high-pressure steam and steam for driving the steam turbine. The medium-pressure steam used by the heater provides the instrument gas source for the air separation unit when it is initially started. After the air separation unit is normally produced, it mainly supplies oxygen to the downstream gasification unit as the raw gas of the gasification unit to participate in the reaction; the pressure nitrogen mainly provides It is used in downstream process production, as stripping gas, sealing protective gas and purge gas; high-pressure nitrogen is mainly used when the downstream purification device is boosted. The by-produced factory air is used by the air separation plant and all downstream chemical industries as instrument gas source and purge gas.

When the air separation unit was originally driven, the power sub-factory provided high-pressure steam and steaming for the air separation unit to drive the turbine. Medium-pressure steam used by heater, air separation device original driving to provide their own instrument gas source, air separation device after normal production, mainly for the downstream gasification device to provide oxygen, as the gasification device raw material gas to participate in the reaction, pressure nitrogen mainly for downstream process production, as a vapor lift gas, sealprotection gas and blow-sweep gas, high-pressure nitrogen gas mainly for downstream purification device when driving up the use. By-product factory air for air distribution and downstream use of all chemical areas, as a meter gas source and blow-sweep gas.

During the initial start-up of the air separation unit, the power plant provides high-pressure steam and steam for driving the steam turbine for the air separation unit. For the medium pressure steam used for the heater, the air separation unit provides the instrument air source for itself when it is initially started up; after the normal production of the air separation unit, it mainly provides oxygen for the downstream gasification unit to participate in the reaction as the feed gas of the gasification unit; the pressure nitrogen is mainly used for the downstream process production, as stripping gas, sealing protection gas and purging gas; the high pressure nitrogen is mainly used for the start-up of the downstream purification unit Use when boosting. The by-product plant air is used for air separation and all downstream chemical areas as instrument air source and purging gas.<br>
