Slop water is a byproduct of cleaning operations on offshore oil and gas rigs, contaminated with hydrocarbons, chemicals, and various wastes. Additionally, it may contain corrosive salts, drilling muds, formation water and solid impurities, posing significant environmental and operational challenges.

Across various processes in the oil and gas industry, including the treatment of water, strict adherence to environmental regulations is crucial. To meet the standards set by the International Maritime Organization (IMO), GEA offers specialized high-performance, self-cleaning centrifugal separators and clarifying decanter centrifuges. The goal is to efficiently reduce the oil content to levels below the legally specified limits, often set at 15 ppm or 5 ppm in some regions.
Continuous and reliable operation, along with cost-effective features such as reduced disposal costs and low energy consumption, makes GEA's solutions suitable for both offshore and onshore applications. The emphasis on compliance, efficiency and cost-effectiveness is a common thread in addressing the challenges posed by oil-contaminated water in the oil and gas industry.
To guarantee adherence to prescribed limits, we employ a specialized oil-in-water measuring device. This device monitors the aqueous phase, ensuring the de-oiled water meets environmental requirements. If oil levels exceed the set standard, the liquid is recirculated to the slop water tank and only released when it meets the necessary purity criteria.
All these various possible compositions make an overboard discharge of slop water inadmissible due to existing environmental regulations, so that they have to be treated before discharge. GEA's approach allows for on-site slop water treatment, eliminating the need for costly transportation to shore for processing and disposal. By efficiently treating slop water at its source, our solution not only ensures compliance with regulations but also minimizes the environmental impact and reduces operational costs.

懸濁液の固体成分を高効率で処理するにあたり、デカンタの時代が到来しました。この機器は、高い浄化効率性と最大限の脱水だけでなく、固体の除去と同時に液体を分離できるようにします。ここでの主な要件は高いボウル速度、巻軸の強力な駆動装置および実現される固体脱水に自動的に順応する巻軸速度です。

GEA の分離機は、液体ベースの用途向けに設計されています。遠心力を利用する分離機は、異なる密度の 2 相以上で構成される懸濁液の分離に使用されます。たとえば、液体 - 液体の分離、液体 - 液体 - 固体の分離、あるいは液体 - 固体の分離に使用できます。これらはいずれも、固体を除去するときと同様、液体混合物を分離するときにも効率的です。
