Can a gas holder have a bypass added?
Thread Content
Can a bypass be added to the gas holder? The gas holder in our company presents high resistance; we now want to divert some gas through a bypass in order to increase the pressure at the inlet of the compression unit and thus boost the volume of gas handled. Are there any relevant standards, specifications, or other guidelines for this?
Bypasses can be added to gas cabinets, but they must comply with relevant safety and technical standards. It is recommended to consult a professional gas equipment design firm for specific design, and to refer to relevant standards and specifications in the industry for modifications. At the same time, it is also necessary to ensure that the upgraded system can effectively improve performance and maintain safe operation. It is recommended to conduct a thorough technical and security assessment before implementation. .
Are there any relevant standards or laws and regulations supporting the addition of a bypass? Thank you!
Before adding a bypass, it is necessary to refer to relevant regulations such as the \"Regulations on Safety Inspection of Pressure Vessels\" and the \"Regulations on Safety Management of Industrial Pipelines\". At the same time, it is also necessary to comply with the \"Regulations on Work Safety in Construction Projects\" as well as the local regulations regarding work safety. It is recommended to work with qualified professional agencies before design and construction, and to obtain review and approval from the relevant authorities. This ensures that the renovation project is legal and compliant, while also meeting safety requirements. .
If there is an SIS system, after adding a bypass, the possibility of loop failure must be considered.
For our former producer gas gas holders, we commissioned the thermal engineering department of a design institute to design bypass branches. The purpose is to clean the maintenance gas holder (which has been in use for a long time), to service the pipelines connected to the gas holder, and to ensure a continuous supply of gas after short-term interruptions during the pressurization process. After the switch, the original intake cabinet compressor is replaced by a direct air supply compressor (with lower power, which results in a lower pressure at the user end). Blind plates must be installed on the parallel valves during operation to prevent cross-ventilation. It is recommended to entrust a design institute to develop a renovation plan. (It doesn’t cost much and solves safety problems.) In addition to buffering and stabilizing pressure, gas cylinders also serve to settle and purify gases. The key is still to address the reason for the high resistance in the gas tank; focus on checking for pipe blockages, the diameters of the inlet and outlet pipes, the diameter of the water seal, and the liquid level.
