A full-scale pertraction installation was successfully put into operation in 1998 by the chemical firm KoSa Netherlands BV in Vlissingen, Netherlands. The pertraction installation is equipped with Liqui-Cel Membrane Contactors [105] (Liqui-Cel website, 2014) containing PP hollow fibers. It treats 15 mVh of wastewater originating from a chemical reactor. The water is heavily polluted with the product formed in the reactor. This product is an aromatic compound. In the pertraction installation, the organic compound is extracted from the wastewater using a feedstock for the reactor as an extractant. Thus, not only is the water cleaned, but lost product is recycled back into the reactor. In light of this pertraction installation, which saves KoSa 5 million m of natural gas annually, the existing wastewater incineration installation could be put out of operation.

Among the commercially available membrane in the market, Liqui-Cel membrane, which is made from PP polymer, is extensively used in membrane contactor systems for pilot plant test. For the last 10 years, membrane contactors have been used in the diverse areas of microelectronics, pharmaceutical, power, food and beverage, industrial photographic, ink, and analytical markets [83]. Among European countries, the Netherlands is actively committed to installing and testing membrane contactor systems for capturing CO2 from flue gas (pre- and post-combustion capture).

Liquid-liquid extraction of hydrophobic oil-laden surfactant solution was evaluated using counter-flow, porous hollow fiber membranes. Our liquid-liquid extraction experiments were conducted using Liqui-Cel Extra-Flow 2.5x8 Membrane Contactor purchased from Celgard LLC (Charlotte, NC). The dimensions of the column are 6.3 cm diameter and 20.3 cm. length with...

A pilot plant on recovery of copper from ammoniacal etching solutions was run with a good performance, as described in refs. [186,187]. LIX54 in kerosene was used as the membrane phase in SLM. Large pilot-plant HF contactors Liqui cel (diam. 25.4 cm, length 71.1 cm) with surface area of 130 m2 have also been used [186]. 

In Figure 25.22, the scheme of experimental setup used for membrane extraction experiments was presented. The setup consisted of membrane contactor with aqueous and organic circuits, two pumps, and the control equipment flowmeters, pressure gauges, and valves. Two phases aqueous and organic solutions circulated countercurrently. Membrane contactor X50 2.5 x 8 Liqui-Cel Extra-Flow, Celgard, was used in the system. The characteristics of the membrane were shown in Table 25.17. The small volume module houses 11,000 capillaries with 1.9 m inner surface area. The module possesses the central baffle, which enables uniform flow inside the shell. 

Commercial fibers or modules have been effectively used to carry out OD. For instance, Cassano et al. [148] used a Liqui-Cel extra-flow MC equipped with microporous PP hollow fibers to concentrate UF-clarified cactus pear fruit juice. The same commercial HF-contactor was used to concentrate pomegranate juice (Punica granatum L.) [149], PP membranes can be prepared through TIPS using suitable diluents as N,N-bis-(2-hydroxyethyl)tallow amine [5] and diphenylether [150],...
