蘇州普希獨家解決方案，TFN特種高壓耐酸膜助力中石化真正實現零排放

蘇州普希環保科技有限公司是國內首家集研發和生產第三代納米復合薄膜型高端反滲透和納濾膜TFN的高新技術企業，是全球范圍內為數不多的特種膜供應商之一。

Proshare Innovation Suzhou Co.,Ltd is the only high- tech company in China design and manufacturer the 3^rd generation Thin Film Nanocomposite (TFN) reverse osmosis membrane and nano filtration membrane ,and become one of the few suppliers in the world produce specialty membrane .

普希工作人員在與中石化的負責人溝通了解到，該廠區廢水來源于脫硫裝置三級循環水和蒸發冷凝水。這兩種廢水有以下特點：

1）氨氮含量高（硫酸銨0.02～0.8%）

2）酸性強（pH≤3）

3）溫度高（50℃）

因此，需要特種耐酸耐高溫膜才能處理這種極具挑戰性水質，基于普希革命性的TFN膜技術優勢，公司獲得了試用機會。

As told by head of factory of Sinopec. the wastewater was originated from the tertiary circulating water of the FGD unit and the evaporation condensate. These two types of wastewater have the following characteristics:

High ammonia-nitrogen content (0.02-0.8% of ammonium sulphate)

High acidic（pH≤3）

High temperature(50℃)

Therefore, special acid and high temperature resistant membranes are required to treat this challenging water quality, based on the revolutionary TFN membrane technology that gave Proshare an opportunity.

傳統技術較多采用“鈣法”進行脫硫，產生硫酸鈣污泥作為固廢進行處理，需要消耗大量的能耗和大量碳排放。

Conventional technologies are more likely to use the ‘calcium method’ for desulphurisation, which produces calcium sulphate sludge that is treated as solid waste and requires significant energy consumption and carbon emissions.

最新技術采用“氨法”進行脫硫，用膜分離的方法處理廢水可以降低能耗，同時經處理的高濃度硫酸銨可用來作為肥料的原料，產生經濟價值。

The latest technology uses the ‘ammonia method’ for desulphurisation, and the treatment of wastewater by membrane separation reduces energy consumption, while the treated ammonium sulphate in high concentration can be used as a raw material for fertilisers, generating economic value.

普希為處理含硫銨脫硫廢水進行深度定制化TFN特種耐酸耐高壓膜以及分離濃縮裝置，實現廢水濃縮高達40倍，濃水的硫酸銨濃度≥20%，大幅減少后續蒸發結晶能耗，為用戶大幅度節約成本，產水水質穩定達到中國石油化工集團公司企業標準Q/SH 0628.2-2014循環水補水要求，真正實現了廢水零排放。這一積極的結果獲得了該集團其他子公司后續的訂單。

Proshare customised TFN special acid-resistant and high-pressure membranes and separation and concentration device for the treatment of wastewater containing ammonium sulphate desulphurisation , achieved wastewater concentration of up to 40 times the concentration of ammonium sulphate concentration of ≥ 20% of the concentrated water, significantly reducing the subsequent evaporation and crystallisation of energy consumption, substantial cost savings for the user, the quality of the water produced by the stable to meet the China Petroleum and Chemical Corporation corporate standard Q/SH 0628.2-2014 circulating water make-up water , and zero wastewater discharge has been truly achieved.

This positive result has gained subsequent orders from other subsidiaries of the group.

普希的該款膜產品同樣適用于其他產生高溫高酸性的含硫酸銨廢水場景，例如能源、煉化、化工、冶金等行業，最新的氨法脫硫技術發展與碳捕集相結合，聯產硫銨、碳銨等氮肥能助力新能源消納和綠色產業鏈發展，符合國家‘雙碳政策’。

This membrane are also applicable to other high-temperature, highly acidic wastewater containing ammonium sulphate scenarios, such as energy, refining, chemical, metallurgical and other industries, the latest development of ammonia desulphurisation technology combined with carbon capture, co-production of ammonium sulphur, ammonium carbon and other nitrogen fertilizers can help the new energy consumption and the development of the green industry chain, in line with the national ‘dual-carbon policy’.
