Kerui provides membrane nitrogen-generation services in Kuwait
T
owards the end of 2016 Kerui Petroleum obtained a membrane nitrogen stimulation contract in Kuwait which, it claims, is set to break the domination of the use of liquid nitrogen locally, and brings a new stimulation product and method to the oil-rich country. The stimulation effect of liquid nitrogen is unsatisfactory in many oil wells because of its low continuity and transportation issues which increase costs. Kerui says that its membrane separation technology continuously generates nitrogen at well sites, which is pumped into the well directly without transportation – cutting costs by around 20%. Hailong Wang, Project Director, Kerui Petroleum, said: ‘The nitrogen unit was applied to three pilot wells when Kerui entered the Kuwait market. Previously, two world-class service giants operated liquid nitrogen stimulation on the second well, but both failed to make well recovery production. Combined with a coiled tubing unit Kerui saved this well successfully and exceeded stimulation expectations after 60 hours of continuous nitrogen injection using a membrane nitrogen generator and booster.’ This project marked Kerui’s breakthrough in Kuwait. Wang says that as the first membrane nitrogen-generation services provider in Kuwait, its technology has enabled it to gain the trust of both oil companies and oilfield services firms. It is aiming to promote this technology and strengthen Kuwait’s nitrogen stimulation market. Wang continued: ‘Kerui will extend cooperation with other oil or oilfield service companies in Saudi Arabia, Oman, United Arab Emirates and other members of the Gulf Cooperation Council, and build a sound oilfield services system in the Middle East.’ Contact: Kerui Petroleum, No. 233 Naner Road, Dongying City, Dongying, Shandong 257000, China.

Membrane Technology
systems and services for industrial and municipal customers, recently signed a definitive agreement to acquire privately held Environmental Treatment Systems Inc, a US firm that operates in the industrial wastewater market. Environmental Treatment Systems serves the food processing, pulp and paper, poultry and meat processing, chemical, beverage, laundry and textile industries. Its clients range from end-users to consulting engineering firms and contractors. ‘We welcome Environmental Treatment Systems to the Evoqua Water Technologies family,’ said Ron Keating, CEO, Evoqua. ‘The company has been a leader in the industrial wastewater market since 1987 and its products and technology, and customer focus and market flexibility have been its hallmarks. We look forward to it joining our team and to helping it accelerate its growth as part of Evoqua.’ Environmental Treatment Systems is becoming a part of Evoqua’s Industrial Projects and Services division – supporting the wastewater needs of its heavy, light and institutional customers, serving a variety of markets. As part of this acquisition this division will form an organic wastewater centre of excellence with Environmental Treatment Systems to serve Evoqua’s industrial customers across its portfolio. Environmental Treatment Systems’ products include dissolved air flotation (DAF) technology, wastewater systems, biological treatment, services and controls. DAF, an effective physical/chemical technology, is used to treat a variety of industrial and municipal wastewater streams. DAF systems are commonly used for the removal of oils and greases and suspended solids, to meet a variety of treatment goals, including product recovery and reuse; pretreatment to meet sewer discharge limits; pretreatment to reduce loading on downstream biological treatment systems; treatment of biological effluent; and thickening of biosolids.
Chemical Co, recently introduced the Specialty Membrane Elements series to provide a reliable, consistent and affordable technology that is capable of tackling punishing operational challenges and intense conditions in the chemicals, sugar, mining, oil and gas, power-generating and dairy markets. The company says that industry demand to operate less resource intensely, in order to meet environmental and economical requirements, calls for new technology and products. These are most needed in markets where highly harmful or highly valuable compounds are being processed and, ultimately, are being separated. Very often these separation processes take place under demanding conditions, requiring specialised technology. ‘The Dow Specialty Membrane Elements complement our reverse osmosis and nanofiltration portfolio well – helping us meet more unique challenges in the chemicals, sugar, mining, oil and gas, power and dairy markets,’ explained Yochai Gafni, Global Business Director, Reverse Osmosis, DW & PS. According to Gafni, this product series also can be used with other Dow technologies, such as ultrafiltration, ion-exchange resins and brackish water or sea-water reverse osmosis (RO). These speciality membranes help users maximise recovery and separation of valuable compounds, reduce their environmental footprint, minimise operational costs and meet regulatory requirements. Andi Gorenflo, Business Development Leader, RO Business Unit, DW & PS, added: ‘Our Dow Specialty Membrane product series enables customers to operate spiral-wound RO and nanofiltration elements under extreme conditions — far beyond the limits of standard elements. This series is a continuation of the RO and nanofiltration success story into new applications for a variety of industries.’ Products that form part of the Specialty Membrane Element series are summarised below.

• Ultra-high-pressure RO elements for industrial process and wastewater – these operate at 1740 psi (120 bar) and increase overall efficiency of minimal liquid discharge (MLD) and zero liquid discharge (ZLD) operations, whilst helping to reduce the size of downstream conventional treatment processes by up to 50%. • High-temperature RO elements for various industrial streams, including those involving sugar – these operate at temperatures up to 80°C, and the Dow Hypershell technology increases cleaning efficiency, reducing cleanin-place chemicals and water usage, compared with standard mesh-wrap elements. • High-temperature nanofiltration (NF) elements for various industrial streams – these
