연안의 석유·가스 생산시설을 위한 제품 및 서비스 공급업체인 Wartsila Water Systems사가 카스피해에 위치한 굴착장치의 하수처리운영을 돕기 위해 공식적으로 NOV Mono사를 선정했다. NOV Mono사는  동공이송식 펌프 제조업체로, 제품을 통해 해저의 반잠수함 심해굴착장치에서 하수처리운영을 도울 예정이다.

Mono사의 Muncher는 시간당 8.8㎥의 처리용량으로 플랫폼에서 발생하는 생활폐수와 목욕배수를 불리는 데 사용될 계획이다.

 

 

 

Wartsila Water Systems Ltd of Poole, a provider of products and solutions for offshore facilities used in oil and gas exploration, development and production, has officially selected NOV Mono, a progressing cavity pump manufacturer, to provide its TR Munchers and three Compact C range pumps for a demanding sewage handling operation on a deep-water semi-submersible drilling rig located in the Caspian Sea. 

 

The Mono TR Munchers will be used to macerate the black and grey water produced on the platform, at a capacity of 8.8m3/h. They are designed specifically for the efficient maceration of abrasive sludges and are very effective in capturing irregular shaped objects, thanks to their layback cutter shafts, which are set at an angle to the incoming flow. The shafts operate at different speeds to tear apart any solids, while a cantilever shaft design reduces the number of wearing components by eliminating the need for bottom bearings and seals.

 

The Muncher also features Mono's EZstrip™ technology, which allows the unit to be maintained in place, thus drastically reducing the maintenance time required and maximizing availability. Any rejected objects are allowed to fall into an easy-access waste trap set below the cutter stacks to prevent damage. Munchers can be supplied to comply with the ATEX Directive 94/9/EC for this type of hazardous area application.

 

The three Mono Compact C Range progressing cavity pumps, which operate with a Wartsila Water Systems Ltd membrane bioreactor, provide a fluid transfer solution that will fit into the compact space of the platform, yet still perform reliably and efficiently at 2-bar pressure. Available in cast iron or stainless steel, and with a choice of rotor and stator materials for different applications, these high-pressure pumps eliminate the need for a series of pumps when pumping over long distances or with high head requirements.

 

They offer a suction lift capability of over 8 meters, and in addition to applications such as this one, their positive-displacement, progressing-cavity action also makes the C Range pumps ideal for accurate process control and variable speed dosing duties. As with the TR Muncher, the Compact C Range pumps can be supplied to comply with the ATEX Directive 94/9/EC.
