Benefits of the BHS Filtration Systems Safe Operation -Benefit for Operators and the Environment Using the well-experienced BHS filtrations systems provides full control of the process to the operator. All relevant operation tasks are utilized fully automatic, totally enclosed and safely separated from the environment. Manual handling is strictly reduced to maintenance work and absolutely minimized. Especially handling of contaminated slurries is avoided completely. Efficient Operation -Benefit for Production BHS Filters are surface filters using the cloth as support for generating the...

Amine Sweetening Process The removal of sulfur and carbon dioxide is one essential step in the cleaning of gas streams. The Amine Sweetening Process is well established for this task. It consists of a gas-amine scrubber (the absorber) followed by further processing of the gas itself and regeneration part for the rich amine to re-useable lean amine. A major obstacle for the good performance of the lean amine are solid impurities (iron oxide, sand, pipe debris etc.), which will build up over time and generate erosion and foaming. The BHS filtration system is applied in the lean amine stream...

MEG Reclamation MonoEthylenGlycol (MEG) is a very common additive to natural gas as a corrosion and hydrate inhibitor when transported in pipelines. The rich MEG is recovered and reclaimed in special process units to lean MEG forcing out water and salts. To avoid massive fouling divalent salt removal is done prior to the thermal water removal by ph-adjustment. The solids loadings are very much depending on the water composition available at the wellhead, but typically the majority is carbonates, followed by hydroxides. A solids loading of several hundred ppm can be achieved easily, the...

Offshore precoat single-stage BHS filtration system for MEG

MEG Reclamation with the BHS Advanced Two-Stage Process (without Precoat) In order to further reduce the consumption of MEG and simultaneously offer compact and low-maintenance packages, BHS has developed a new combined “filtration-washingdrying” process that does not need any precoating or chemicals. The advanced two-stage process is as an alternative to the classical precoat process, combining Candle Filters without precoating for concentrating the sludge followed by a second filtration using a Pressure Plate Filter. The first step is used as a purification and pre-thickening step to...

Solid Sulfur Separation Sulfur is a major contaminant in the oil and gas industry that exists in various forms and has to be removed before further processing. In recent years the removal of sulfur species has received increasing attention because of safety concerns, the need to reduce emissions of sulfur oxides (SOx), and the fact that sulfur harms the combustion properties of fuels. Sulfur removal has to be applied to conventional fuels applications such as high pressure natural gas from onshore    ffshore production, hydrogen from refinery /o hydrodesulphurization, fuel gas in refineries...

Water Scrubbing & Grey Water The BHS Candle Filter system can be applied to a range of refining and gas processing applications to remove fines from circulating scrubbing liquids. In all these applications fine particulate matter from the recirculating liquid streams has to be removed for efficient scrubbing operations. The particulate matter can be catalyst fines and other contaminants in the feedstock. The use of thin-cake Candle Filter system has been proven to be cost-effective and reliable approach to removing these fines, recovering the scrubbing liquids and drying the cake for easy...
