DESCRIPTION:
BRIEF SUMMARY
The invention relates to a process for catching and processing of non-aqueous drip-liquids, and to a liquid catching cloth for use therein.
In everyday household and industry practice, drip-liquids of oily nature are frequently caught. This catching takes place with granules or a liquid catching cloth, which in its simplest form comprises absorbent paper or a loosely-woven or non-woven textile material. Once the catching material is somewhat soaked, it is removed and discarded. At the place of the leak, granules are sprinkled or a new catching cloth is laid.
The waste disposal of the caught materials with substantial amounts of absorption constitute a problem, namely the processing of large amounts of accompanying materials and the process of many different kinds of caught materials, among which may be materials present which cause environmental pollutive effects. The catching of drip-liquids occurs very frequently in the industry. There may be mentioned the automotive industry, garages, the printing trade, and metallurgical industry, ship engines, the food processing industry and certainly not in the last place the oil and chemical industry, whereby all kinds of non-aqueous and also aqueous liquids may pollute the working floor and should be taken up. It is noted also that aqueous liquids can do so and that they interfere in the absorption of other water immiscible liquids since aqueous liquids are caught in many absorbents.
Liquid catching cloths are also known, which lack this disadvantage and which are water-repellent, that is that they do not show or hardly show an affinity for water and aqueous liquids, but they do show a high absorptive power for oils and hydrophobic chemicals. From these compounds they can catch a lot (up to 25 times their own weight) and they do so fast too. They are products on a non-woven synthetic resin basis, mostly polypropylene micro fibers fleeces.
So far these liquid catching cloths were used predominantly for the removal of oil and chemicals from surface waters. For catching and removing of drip-liquids, the product has not found acceptance. The initial expenses are too high therefor.
It has now been found that this aspect, as well as the presence for the used cloths in the waste stream and thereby the complication of the processing of that waste stream, can be prevented.
U.S. Pat. No. 2,198,164 discloses a process for cathing non-aqueous drip-liquids in a liquid catching cloth where the drip-liquids are caught in an oily and non-aqueous liquid absorbing liquid catching non-woven cloth, incorporated in an envelope of a fabric which envelope with cloth is partitioned in a suitable manner of tracks or fields. After usage of such cloth it has to be disposed of, which pollutes the environment.
The present invention provides a process for catching in a liquid catching cloth and processing non-aqueous drip-liquids, in which the drip-liquids to be processed are caught in an oily and non-aqueous liquid cathing non-woven cloth, incorporated into an envelope of a fabric, which envelope with cloth is partitioned in a suitable manner in a number of tracks or fields, characterized in that the liquid cathing cloth is water-repelling; the envelope is of a hydrophobic synthetic resin fiber; the enveloped liquid cathing cloth with absorbed drip-liquids is collected; the collected enveloped liquid cathing cloths are washed in a solvent for the drip-liquid; the drip-liquid is separated from the solvent; the drip-liquid recovered is incinerated with power-generation and the cleaned enveloped liquid catching cloths may be used anew.
Further the present invention provides a cloth on a non-woven basis for use in the process suited for catching oily and non-aqueous drip-liquids and incorporated into an envelope of a fabric, which envelope with cloth is partitioned in a suitable manner in a number of tracks or fields, characterized in that said cloth is water-repelling and said envelope is of a hydrophobic synthetic resin fiber.
It is noted that the liquid catching non-woven cloth as such is usel
