XS-C50 Online Detection and Control System

According to the rapid development of the domestic gas industry, with the continuous increase of labor costs and the impact of special environments (toxic, polluting, and dangerous) in chemical enterprises, the use of online automatic detection systems is the main tool for chemical enterprises to improve analysis timeliness, reduce manual operation errors, improve analysis accuracy, reduce employee labor intensity, and improve automation level. Shanghai Xuansheng Scientific Instrument Co., Ltd. has developed a gas detection system based on the requirements of gas manufacturers and chemical enterprises for gas detection in their production processesXS-C50 Online Detection and Control System.

Principle:

This system is implemented by laying pipesAvenueholdTestedGasBy suction pumpDraw toGas chromatograph for detection.detection resultfromAnalysis work softwareconducthandleThe entire process is carried out under microcomputer control, with a high degree of automation.Open the system,beforeBy samplingpumpextractPipeAvenuewithinGasForming negative pressure, i.eTested gasThe external pressure is greater than the pipeAvenueThe internal pressure makesTestedGas suction pipeAvenueBefore reaching the solenoid valve, it is in a waiting state for detection.

The analysis results are fromAnalysis workThe software processes and generates spectra and analysis results, which are displayed on the screen and printer respectively, completing the detection and analysis process of a certain gas path. When multiple detections are required, the microcomputer automatically cycles according to the user's set detection sequence and number of detections, without manual intervention, and can achieve 24-hour continuous online detection and analysis. All analysis data can be retained. In order for the staff to reuse the data.

Main features:

1. The box adopts an integrated cabinet structure with metal sheet upright, positive pressure explosion-proof box, explosion-proof grade: ExPxd Ⅱ CT3, suitable for various explosion-proof places.

2. By using the Windows control system on the computer, the operation is simple and easy to learn. There is no limit to the number of database records, and historical data can be analyzed and compared. The Modbus/TCP server built into the workstation can connect the analysis results to DCS (Distributed Control System)

3. Sampling can be done under positive or negative pressure. The system is programmed to automatically sample periodically and continuously monitor and calibrate the process sample gas without the need for manual verification. In areas where pipelines have not been laid, manual sampling and testing can also be used, which is flexible, convenient, and reliable. The maximum sampling distance of the pipeline is no more than 5 kilometers, and the software controls 48 channels.

4. Injection method: supports packed column and capillary column injectors; Can be equipped with 4-way, 6-way, 10 way, and 12 way valves for sample injection; Multiple gas components are injected at the same time to produce results.

5. Detection methods: Multiple detector options, such as FID, TCD, ECD, FPD, NPD, PID, and PDDID, etc;

6. Running time: 24-hour automatic cycle monitoring or manually set.

7. System error: ≤ 1.5%

Widely used in various fields such as petrochemicals, mine gases, smelting, coking, synthesis gas, coal gas, natural gas, liquefied gas, and toxic gas detection (such as hydrogen sulfide, sulfur hexafluoride, sulfur dioxide).
