The solvent recovery devices in many enterprise workshops have been in operation for a long time: the type selected according to the process and gas volume at that time, now the process has changed, the gas source has changed, and the emission requirements have also changed. Whether the device can continue to be used, whether it should be modified, and to what extent, a clear evaluation conclusion is needed. LuoyangWohong PetrochemicalEquipment Co., Ltd. provides evaluation and renovation and upgrading services for solvent recovery units. Starting from on-site verification, the current situation, short board and renovation boundary of the units are listed item by item, and then the renewal path is given.
The assessment does not simply look at the old and new equipment, but at the gap between its current capabilities and actual needs. The verification contents include four categories: first, the actual processing capacity of the device, which is checked with the current gas concentration; Second, the status of key components, heat exchange surfaces, seals and control systems are checked item by item. The third is to collect the integrity of the system and see which exhaust points are not connected. Fourth, the standard on the discharge side is judged according to the measured outlet concentration.
The evaluation conclusion usually falls on one of the three paths: if the main body of the device is in good condition but only the local capacity is insufficient, local expansion or component replacement is sufficient; If the main body is still there but the process is obviously not matched, supplement and upgrade the process links, such as adding membrane separation or adsorption unit on the basis of the original condensation; If the device is old, has many hidden dangers and is not economical to transform, consider the replacement of the whole machine or skid. The three paths are judged on the basis of the ratio of the transformation input to the expected effect, and the evaluation report will give a comparative conclusion for decision-making.
Compare the transformation input with the replacement input, and consider the remaining service life and the degree of hidden danger. The evaluation report will list the input, effect and implementation difficulty of the two schemes together for decision-making.
Most of the renovation can be carried out in combination with the maintenance window or in batches. The prefabrication work in the factory is completed first, and the on-site connection is mainly taken over. The shutdown time is as short as possible.
To check paragraph by paragraph. The intact pipe section and valve can be incorporated into the new scheme to continue to use, rust or do not meet the current requirements of the paragraph item by item replacement reasons.
The implementation of the renovation shall be combined with the workshop maintenance window as far as possible. The prefabricated work in the factory shall be completed in advance, and the site shall be mainly connected with takeover, wiring and debugging. Deliverable contents include renovation plan, construction records, commissioning data and operation and maintenance documents, and simultaneous training of post personnel during commissioning. After the transformation is completed, it is suggested to make a one-time return visit to check whether the transformation goal is achieved with the actual operation data.
