Evonik and SINOPEC to collaborate in OSN membrane technology

DuraMem® and PuraMem® – Integrate solvent-stable membrane technology.

The German specialty chemicals company Evonik Industries AG and the SINOPEC Beijing Research Institute of the Chemical Industry (BRICI) have signed a collaboration agreement to build a process development laboratory for Organic Solvent Nanofiltration (OSN) membrane technology.

Based on its solid technical expertise and comprehensive OSN product portfolio, Evonik will act jointly with BRICI to develop new processes for Sinopec. “Starting up the OSN lab is a consistent step in our growth plan for the attractive membrane business,” noted Dr. Dominic Stoerkle, vice president and general manager of the High Performance Polymers Business Line Asia Pacific at Evonik. “Based on the close partnership with BRICI and our active participation in the open platform, we anticipate further growth to result from the new joint OSN laboratory.”

Professor Li Hongbo, president of the Yanshan Branch of Sinopec BRICI, particularly emphasized his organization’s willingness to enter into a more extensive cooperation with Evonik: “The joint OSN laboratory is a novel approach to fostering collaboration. It is well aligned with our regional innovation strategy and future development vision. Evonik will contribute advanced technology, which SINOPEC will make accessible to various business stages. With Evonik’s support, we will also build up a pilot plant unit in one of Sinopec’s production sites as an OSN reference plant.”

Founded in1958, SINOPEC Beijing Research Institute of the Chemical Industry (BRICI) is a pioneering institution in China dedicated to comprehensive research for the petrochemical industry. When Evonik initiated the first contact with BRICI in 2015, both parties showed strong interest in potential OSN applications for the petrochemical industry. In the following year, a series of laboratory-scale tests were successfully conducted for a lube oil dewaxing application. To enter into a partnership with the aim of developing more processes and setting up a long-term collaboration, both sides initiated several management-level meetings to discuss a future collaboration strategy. The joint OSN laboratory was officially established in early 2017, when Evonik’s first (lab-scale) equipment arrived at SINOPEC BRICI.

In the future, the laboratory will focus on the petrochemical industry to open up substantial markets in both China and the entire Asian region for OSN applications.

What is OSN? Organic Solvent Nanofiltration (OSN) is an innovative and environmentally friendly membrane technology, which has a wide range of applications in the petrochemical, pharmaceutical, fine chemicals, and food industry.

LANXESS reverse osmosis membrane elements completes test

  • Reverse osmosis membrane elements from LANXESS prove their value in Zellstoff Stendal water treatment
  • Application in Germany’s largest industrial water treatment plant
  • ASD feed spacers impress with a consistently high level of rejection
  • New element grades deliver energy savings of up to four percent

Reverse osmosis membrane elements from specialty chemicals company LANXESS have successfully completed a year-long practical test in Germany’s largest industrial water treatment plant. The new element grades with ASD feed spacers impressed Zellstoff Stendal GmbH based in Arneburg with their performance and consistently high level of rejection. Optimized for applications in brackish water, these Lewabrane-branded elements are characterized by very low energy consumption (LE = low energy) and high fouling resistance (FR = fouling-resistant).

“The outstanding results of our ASD products in benchmark tests with other manufacturers at one of the largest pulp manufacturers in Europe once again underline the extraordinary quality of our products,” said Alexander Scheffler, responsible for LANXESS’s global membrane business.

One year ago, Zellstoff Stendal launched a project to test LANXESS’s newly developed Lewabrane ASD range of membrane elements. This involved installing conventional reverse osmosis (RO) elements with a standard feed spacer and FR elements with LANXESS’s new ASD spacer in parallel in a single pressure vessel. The LANXESS spacers have a special “netting” that reduces biological growth and particle fouling by minimizing dead zones. The netting has an alternating strand design (ASD) of thin and thick filaments, which is what gives the spacer its name.

Frank Gorges, plant technician for water treatment at Zellstoff Stendal GmbH in Arneburg, was excited about the result: “We were very impressed by the performance of the ASD membrane elements from LANXESS. We test a lot of products in our plant and hardly any of them have been able to provide such consistently high results throughout an entire year.”

During the period of the project, the LANXESS RO elements demonstrated excellent performance and impressed with a consistently high level of rejection. This has a positive effect on the service life of the mixed bed and the amount of chemicals required for regenerating the ion exchangers.

After one year, the elements were removed and taken to the applications laboratory LANXESS operates in Bitterfeld for an “autopsy”. Compared to a standard element, there was hardly any increased pressure drop along the element when using the ASD grades. This indicates less blockage from fouling or biological growth.

Improved productivity 

In addition to the fouling-resistant Lewabrane B400 FR ASD grade tested by Zellstoff Stendal, LANXESS also offers Lewabrane B400 LE ASD, another premium product where the innovative feed spacers have improved productivity by four percent. For users, this means potential energy savings of approximately the same percentage.

Computational fluid dynamic (CFD) simulations had previously indicated that RO elements with ASD feed spacers would indeed be capable of achieving higher performance levels than standard grades. Furthermore, the tendency toward fouling in the element is reduced. “As we calculated, using the new elements reduces energy requirements while at the same time increasing service lives,” said Dr. Jens Lipnizki, head of Technical Marketing Membranes in the Liquid Purification Technologies (LPT) business unit at LANXESS.

LANXESS water treatment technologies for pulp manufacturing

Zellstoff Stendal, part of the American-Canadian Mercer International Group, is the largest and most cutting-edge manufacturer of NBSK (Northern Bleached Softwood Kraft) market pulp in Central Europe. With their outstanding properties – especially their high tensile strength and high degree of whiteness – these pulps are used, for example, for high-quality printing and copying paper, wallpaper bases, household paper such as paper tissues and kitchen roll, filter paper and a range of other specialist papers like silicone base paper.

Wood elements such as bark and lignin that are not used for pulp production are incinerated in boiler plants. A combined heat and power process in this case generates heat energy that is used as process steam and electricity. Located in the north of Saxony-Anhalt, the plant generates enough power to cover its own needs and also feeds a large part of the renewable energy generated into the public electricity grid.

More than 50,000 cubic meters of water are needed every day for pulp manufacturing in Arneburg, and this is treated using reverse osmosis and ion exchange resins. The Lewatit MonoPlus S 100 and Lewatit MonoPlus M 600 grades are used in the multistep process, while Lewatit MonoPlus SP 112 H and Lewatit MonoPlus MP 500 are used in the mixed bed.

Automotive Filter Aftermarket to Exceed $4 Billion by 2021

Oil filters comprised the largest share of the North American automotive filter aftermarket

Aftermarket demand for automotive filters in North America is forecast to advance 2.4% per annum through 2021 to $4.1 billion. Sales will be boosted by:

  • Growth in the size of the region’s light vehicle park and the number of miles driven annually
  • High income levels in the US and Canada and rising income levels in Mexico
  • Ongoing consumer education efforts by manufacturers and automotive technicians regarding the replacement of cabin air filters
  • Increases in raw material and product prices
  • Relatively stringent environmental regulations in the US and Canada and the enactment and enforcement of stricter environmental controls in Mexico

Oil filters comprised the largest share of the North American automotive filter aftermarket in 2016, totaling $1.6 billion in sales and representing 44% of the market. These products hold a leading share of the market due to the frequency with which oil changes are performed (and the associated filters replaced) as a part of routine maintenance. These and other trends are presented in Automotive Aftermarket for Filters in North America, a new study from The Freedonia Group, a Cleveland-based industry research firm.

Engine air intake filters commanded the second largest share of regional aftermarket filter demand in that year, accounting for 31% of overall sales. This share of demand is down from a decade ago, reflecting product improvements that lengthen the useful lifespan of air intake filters.

More information about the study is available at Freedonia’s website.

MOGUL Madaline Fills the Gap in Nonwoven Fiber Technologies

Nonwovens producer Mogul, recipient of two IDEA Entrepreneur awards, has once again introduced a new product with unique nonwoven properties.  The new product, Madaline®, fills the gap in nonwoven fiber technologies by having the strength of a spunbond together with microfilaments with size equal to or smaller than that in meltblown fabrics.

Madaline uses a patented bico technology of polyester (PET) / polyamide (PA) for producing continuous filaments with multiple fiber geometries. The filaments can be extruded in two different filament shapes: “Hybrid Mix” or “Multi-Lobal.” These continuous filaments are subjected to high pressure water jets, which split them into filaments less than 5 microns while also entangling these fibers and consolidating them into a dense web. This process allows Madaline to be made without binders and avoids holes associated with needle-punch products.

The resultant Madaline fabric provides very efficient filtration properties with the strength of a spunbond. The combination of filtration properties and high strength will allow the use of lower weights at equivalent efficiencies, with lower pressure drop, which means reduced energy consumption and improved sustainability.

Additionally, the Madaline process produces mixed fibers, comprising both large and very small fibers throughout the web. Such a mixture of fiber sizes results in filtration properties of longer life and lower pressure drop with equivalent air efficiency compared to structures in which all the very small fibers are in a single layer. Envisaged filtration applications of Madaline are for liquid filtration applications and as a replacement for micro-glass for high end filtration.

Madaline is produced up to 200 gsm at web widths of 3000 mm. The product offers spot-to-spot uniformity for heightened reliability; also its continuous filaments mean reduced fiber migration thereby adding strength and ensuring freedom from lint. Due to microfilaments Madaline breathes well, which makes for good moisture management i.e., absorbing and speed of drying. The strong structure provides a fabric capable of multiple washes.  It also exhibits very good thermal insulation, wind resistance and UV protection.

In addition to filtration, Madaline can be made to be very soft and drapable for a wide range of other applications including textile applications (replacing woven and knitted fabrics), clothing, scratch free wipes, etc. Madaline can be finished with processes such as dying, printing and stitching, similar to textile fabrics.

The Madaline process produces a Polyester/Polyamide fiber, which is sometimes also referred to as a polyester/nylon bicomponent fiber.

The raw materials in the Madaline product complies with the requirements of the Commission Regulation (EU) No 10/2011 of 14 January 2011 on plastic materials and articles intended to come into contact with food most recently amended by the Commission Regulation (EU) No 2016/1416 of 24 August 2016.
