變壓吸附制氫,氮,氧,裝置

利用壓力變化時氣體中的不同組分在吸附劑上的吸附容量不同的特性,脫除氫氣中的雜質,制取高純氫氣?蓮慕範t煤氣、煤氣、催化裂化干氣、合成氨尾氣、苯乙烯裝置含氫尾氣等含氫氣源出發,多種技術相結合,制取高純氫氣。


特點:
工藝方面:因地制宜將TSA、PSA、VPSA、氣體純化技術結合在一起,為用戶提供最完善、經濟的工藝解決方案:純度高,回收率高。
吸附塔方面:采用氣體分布效果更好,床層死空間更小的新型結構,具有較高的氣體回收率。
吸附劑方面:采用國家催化中心研制的高效變壓吸附吸附劑、催化劑、產氣純度高、使用壽命長。
控制系統方面:采用西門子S7系列PLC,可保證用戶自控系統的穩定性及可靠性?蓪崿F連續自(手)動切塔與恢復操作、變壓吸附壓力終升及沖洗壓力的自適應調節。裝置參數自動優化、系統安全聯鎖等功能,達到了國際先進水平。
程控閥門方面:采用國內外著名閥門廠所生產的最新三偏心金屬密封蝶閥(開關一百萬次無泄漏),可根據用戶需要提供氣壓驅動伙食液壓驅動的程控閥門驅動系統。


PSA Hydrogen, nitrogen, oxygen plant

Using the different adsorption capacity of different components in the gas on the adsorbent when the pressure changes, the impurities in the hydrogen are removed to produce high-purity hydrogen. High purity hydrogen can be produced from coke oven gas, gas, FCC dry gas, synthetic ammonia tail gas, hydrogen tail gas of styrene unit and other hydrogen gas sources by combining various technologies.

Characteristic:

Process: combine TSA, PSA, VPSA and gas purification technology according to local conditions to provide users with the most perfect and economic process solution: high purity and high recovery rate.

In the aspect of adsorption tower, a new structure with better gas distribution effect and smaller dead space of bed layer is adopted, which has higher gas recovery rate.

In terms of adsorbent: high efficiency PSA adsorbent, catalyst, high purity gas production and long service life developed by national catalytic center are used.

Control system: Siemens S7 Series PLC is used to ensure the stability and reliability of the user's automatic control system. It can realize the self-adaptive adjustment of continuous automatic (manual) cutting tower and recovery operation, final pressure rise of PSA and flushing pressure. The automatic optimization of device parameters, system safety interlock and other functions have reached the international advanced level.

In terms of program-controlled valve: the latest three eccentric metal seal butterfly valve (one million times of opening and closing without leakage) produced by famous valve factories at home and abroad is adopted, and the program-controlled valve drive system driven by air pressure and food hydraulic pressure can be provided according to the needs of users.
