대규모 화학 생산공장이 새 시설에서 염소알칼리 공정의 한 부분인 프리코트(precoat) 여과 처리를 개선하기 위해 Pall Corporation사의 새 염수여과 기술을 도입했다.

 

Pall사는 설계 및 엔지니어링 회사인 Pall Carbo™와 협력해 설계를 진행했으며, 플랜트의 특정 요구사항을 충족하기 위해 회사에 축적된 경험을 활용, 여과 기술을 조정해 설계에 유연한 옵션을 지원했다.

염소 알칼리 공정은 염화나트륨의 전기 분해를 위한 산업 공정으로, 전 세계에서 가장 널리 사용되는 두 화학물질인 염소와 수산화나트륨 생성에 이용되는 기술이다.

 

 

 

In an effort to better handle precoat filtration as part of the chlor-alkali process at a new facility, a large chemical producer in the city of Abu Dhabi, Arab Emirates, has installed a new brine filtration technology from Pall Corporation, a specialist in filtration, separation and purification solutions and technologies.

 

Pall worked closely with an engineering firm to design the solution, called Pall Carbo™. Leveraging past experience with the firm, Pall was able to offer flexible options to support its design efforts and tailor the company's filtration technology to meet the plant's specific requirements.

 

The chlor-alkali process is an industrial process for the electrolysis of sodium chloride. It is the technology used to produce chlorine and caustic soda, two of the most widely used chemicals in the world. Chlorine and caustic soda are produced by the electrolysis of aqueous solutions of alkali metal salts. This process requires the removal of dissolved contaminants from the brine solution prior to the electrolytic process.

 

Precoat filtration requires a filter aid that coats the element. During this process, the filter aid and the filtered solids form a "cake," which works as a strainer to collect much finer contaminants. The filter aids used in precoat filtration have an affinity for the rough Carbo element surface, making the filters ideal for use in these applications. Carbo filter elements also feature excellent resistance against salt solutions.
