CO compensation supply system on CO conveying pipeline and application of CO compensation supply system

Abstract

The invention relates to a CO compensation supply system on a CO conveying pipeline and application of the CO compensation supply system. The CO compensation supply system comprises a CO liquid tank used for storing liquid CO and a vaporizer for vaporization of the liquid CO. The vaporizer is provided with a first heat exchanger, a second heat exchanger and a third heat exchanger used for vaporization of the liquid CO. A first pipeline, a second pipeline and a third pipeline are led out of the CO liquid tank. The first pipeline is connected with the first heat exchanger, the second pipeline is connected with the second heat exchanger, and the third pipeline is connected with the third heat exchanger. A first gas CO supply pipeline is led out of the first heat exchanger and connected to the CO conveying pipeline. A second gas CO supply pipeline is led out of the third heat exchanger and connected to the CO conveying pipeline. A backflow pipeline is led out of the second heat exchanger and connected to the first pipeline. Each pipeline is provided with a valve. The system is convenient to operate, and different compensation amounts can be controlled according to the situation of inner pressure of the CO conveying pipeline.

Description

technical field [0001] The invention relates to a CO supply system, in particular to a CO compensation supply system on a CO delivery pipeline and its application. Background technique [0002] HyCO is hydrogen + carbon monoxide (Hydrogen + CO). In a narrow sense, HyCO is a chemical process that simultaneously produces hydrogen and carbon monoxide. Since carbon monoxide is usually produced simultaneously with hydrogen, HyCO is used in the gas industry to indicate a chemical production plant whose main product is hydrogen and / or carbon monoxide and / or a mixture of hydrogen and carbon monoxide (synthesis gas, or Syngas). or production process. [0003] The CO products produced by HyCO are generally boosted by compressors and delivered to customers through pipelines. However, if there is a problem with the device or the compressor, the CO product will be interrupted, and the customer's device will trip, which will cause a certain degree of damage to some equipment. Injury an...
