PLC Controlled Nitrogen-Ammonia Mixed Gas Pressurization and Separation Equipment to Manufacturing

The system design allows for fluctuation in intake pressure, with the maximum being 2.2 KPa above the base level of 2 KPa. If the pressure is lower than 2 KPa, the booster pump may fail to draw in properly, resulting in a decrease in the outlet flow rate. If the pressure is too high, it is recommended to install a pressure reducing valve or a buffer tank at the front end to prevent damage to the pump head.

The medium is a strong corrosive and explosive nitrogen gas mixture (which may contain ammonia, hydrogen sulfide, etc.), and 316 stainless steel has better resistance to chloride ions and acidic corrosion compared to 304. Only when there are absolutely no 316 material spare parts available, can 304 be used, and it is only permitted for non-critical moving parts (such as supports, flange outer edges, etc.).

After the entire machine is assembled, all the pipelines and cavities undergo chemical cleaning, degreasing treatment, and are then blown clean with oil-free compressed air. Before leaving the factory, the key inner walls were wiped with white silk cloth, showing no oil stains or particles. The iron filings are removed through endoscopic inspection and magnetic adsorption technology. A cleanliness inspection report is also provided along with the equipment.

3MPa represents the lowest pressure that the system can consistently output under the rated processing capacity (20L/min). The actual outlet pressure can be adjusted by the PLC to control the power of the air compressor or the stroke of the booster pump, reaching a maximum of 5 MPa (please confirm the model of the pump set). The factory default setting is 3.2 MPa. Users can set the upper and lower limits on-site.

DG02A is a low-pressure high-flow boosting stage, suitable for increasing the pressure from 2 KPa to approximately 0.5 MPa. DCA05 is a high-pressure low-flow boosting stage, which further increases the pressure to above 3 MPa. Two units configured in parallel or series can ensure that the system can continuously and stably output at a processing capacity of 20L/min, and they can also serve as backups for each other, thereby enhancing reliability.
