ENVIROGENWATER TECHNOLOGIES

World Class Filtration Technology for the Oil and Gas Industry

A Total Solutions Provider

21st Century High End Filtration Solutions for Oil and Gas Industries Fluxa Filtri, a divison of Envirogen Water Technologies, has extensive experience in the oil and gas sector, offering water treatment and filtration systems for petrochemical and oil industries, gas and air treatment as well as refinery operations

We understand how critical water is in oil and gas processing, and how trace contaminants in the water supply can adversely impact vital processes. The separation, treatment and disposal of produced water can be one of the most costly and environmentally challenging dilemma’s facing the oil and gas industry today.

To help manage oil and gas water needs, whether it’s upstream, or downstream, we offer a complete range of innovative process solutions, operations and maintenance services for water treatment, water recovery and water reuse ensuring efficiency and sustainability.

State of the Art Filtration Cartridges With production and process costs constantly being driven down yet optimal performance a must, process specialists need cartridge filters with long life, high efficiency and low operating cost.

Whatever the filtration or separation need, the extensive Fluxa Envirogen cartridge range provides a modern and efficient solution. The latest manufacturing equipment is used to produce consistently efficient filters at low costs, engineered to meet the specific requirements of the oil and gas industry.

Critical Quality Control Every product supplied is quality control checked, tested and guaranteed to international standards giving the peace of mind and assurance you need. Manufactured in controlled environments using well defined and documented work instructions and quality plans, ensures the highest quality and cleanliness standards are consistently maintained.

Full traceability back to the raw materials used is enabled through the use of part Numbers and batch numbers. Products are validated and tested using a modified single pass test methodology with standard test dust and typically achieved Beta 5000 at their respective micro ratings

UpStream ApplicationsWater InjectionInjection of water is required to maintain reservoir pressure and increase the recovery factor in oil production, but the importance of effective water treatment is often underestimated. Water intake quality can vary tremendously and this will have significant impact on the performance of the water treatment facilities. Poor quality injected water may result in clogging of the reservoir and loss of oil production. Envirogen supplies filters designed to be used throughout the water treatment process to help ensure it functions to optimum levels. Whether the application is fixed or floating, seawater or freshwater we are able to provide easy operating, cost effective solutions to help maximise the production of water for injection.

Coarse FiltrationCoarse filtration is an important step in ensuring the critical treatment and filtration systems further downstream function effectively, by removing bulk contaminants such as sand, silt and seashell fragments etc. These filters are typically rated between 25 and 100 µm.

Guard / Fine FiltrationRemoval of fine particulates from water to be injected is important to avoid plugging of the reservoir and hindering oil recovery. The fine ‘Guard’ filters are used to remove particles ranging from 1 to 50 µm. Protecting either the well or other water treatment processes, these absolute filters should offer absolute retention of particulate contaminants as well as maximise membrane life, reduce replacement costs and avoid unexpected interruptions to the process.

SeaWater RO Protection - MembranesReverse Osmosis is typically used to produce potable water and the high purity water used in potable water makers. RO membranes require fine prefiltration to ensure long life, Envirogen supply cartridges rated at 5-10 µm absolute for this application. These are available as either standard cartridges or in the large diameter, high flow format.

Produced WaterContaminated produced water requires significant processing to allow reuse or disposal. This is a multi-step process and typically the system contains bulk oil separators, cyclones, degassers and polishing filtration. Envirogen supplies high efficiency polishing absolute and nominal rated filters to help ensure the solids levels are reduced to the desired level. Envirogen also supplies cartridges for the removal of hydrocarbons from water. Typically used as polishing units downstream of primary removal equipment, they offer up to 99% removal of oil and emulsions where contamination levels are up to 500mg/l.

DownStream ApplicationsOil and gas refining relies on the effective operation of complex processes and equipment. The function of these can be adversely affected by particulate contamination in the feed streams. Envirogen has used its knowledge within refineries to develop a range of filtration systems designed to help keep the processes functioning at peak performance.

Inlet Gas SeparationField gas will be processed to remove solid, deformable and liquid contaminants prior to amine sweetening. This typically involves multi-stage separators, coalescers and particulate filters. Envirogen has a range of products that are used as a fine filter typically located between the separators and coalescers. For this application we are able to offer a range of products manufactured with either polypropylene or nylon media to provide long operational life and good protection to the coalescer.

Amine SweeteningEffective control of particulates in the amine used to treat sour gas is vital. Contamination such as Iron Sulphide particles can have a negative impact on the equipment. Ideally the recirculating amine should contain < 1ppm solids and Envirogen is able to offer a range of cartridges to help achieve this. Filters are available in a range of removal ratings and typically are used prior to the contactor and regeneration system and also downstream of the carbon bed to capture any carbon fines that are shed.

Glycol DehydrationMany problems in a glycol dehydration plant can be traced to an excessive amount of liquid and solid contaminants present in the process stream. Recognising that process conditions may vary widely, we supply both nylon and polypropylene media filters to ensure the optimum filter can be chosen. These are available in a range of removal ratings so the choice of filter can be tailored to the size of contaminating particles

Catalyst BedsCatalysts beds are used throughout the refining process and can be negatively impacted by particulate contamination in two main ways. Fine particles can plug the flow pathways within the catalyst bed and general particulate contamination can cause deactivation of the catalyst. The use of either polypropylene filters or nylon filters rated at 5-10 µm are an effective method to reduce the occurrence of these problems. For more critical applications, we also offer cleanable sintered metal and woven mesh elements for high temperature and aggressive gas processes.
