EFFICIENT PROCESSING OF DRILLING SLURRY Whether on oil platforms or in other industrial applications, the continuous cleaning of drilling liquids such as drilling slurry, flushing fluids and drilling mud is crucial for the trouble-free operation of modern drilling systems. At the same time, environmental protection requirements are increasing, especially with regard to the prevention of groundwater and marine pollution. Flushing fluids perform a variety of tasks: they cool and lubricate the drilling tool and reliably transport cuttings. The composition is complex – they are made up of water,...

SLOP WATER PROCESSING When offshore oil and gas platforms are operated, slop water – a complex mixture of hydrocarbons, chemicals, drilling muds, salts, sand, solids and water – is produced during cleaning work on the pipe and drilling deck. These highly contaminated liquids often contain erosive and corrosive components that prevent direct discharge into the sea according to environmental regulations. Flottweg offers an efficient and on-site solution for the treatment of slop water. By mechanically separating the phases, the water is purified to the extent that it meets the legal requirements...

QUALITY-OPTIMIZED CRUDE OIL PROCESSING In addition to the actual product, large amounts of gas, water and solids are also produced during the extraction of crude oil. Before the crude oil can be transported and further processed, it must meet defined quality standards – especially with regard to the content of water and sediment (BS&W – Basic Sediment & Water). Flottweg offers custom-made centrifuge solutions for the dewatering and purification of crude oil, which reliably separate water, dissolved salts and fine particles. The separation technology used optimizes the overall process and reduces...

COMPLETE SLOP OIL PROCESSING From waste to valuable material Slop oil is produced during the cleaning of oil tanks, in filter recovery processes or as a by-product in refineries – for example, through leaks or overflows. It is a complex mixture of oil, water, chemicals and coarse and fine particles, the composition of which can vary greatly. Efficient pretreatment for stable processes In the first step, the slop oil is heated to process temperature and is mixed with suitable chemicals (e.g. demulsifiers) to break down emulsions. In special mixers, the medium is homogenized – an important prerequisite...
