Abstract
Abstract A process for catching and processing non-aqueous drip-liquids, characterized in that the drip-liquid to be processed is caught in an oily and non-aqueous liquids absorbing, water-repelling, liquid catching on a non-woven cloth, incorporated into an envelope of a hydrophobic synthetic resin fiber fabric, which envelope with cloth is partitioned in a suitable manner in a number of tracks of fields; the enveloped liquid catching cloth with absorbed drip-liquid are collected, the collected envelope liquid catching cloths are washed in a solvent for the drip-liquid, the drip-liquid is separated from the solvent, the drip-liquid so recovered is incinerated with power-generation and the cleaned enveloped liquid catching cloths may be used anew.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
A process for catching and processing non-aqueous drip-liquids, in which the drip-liquids to be processed are caught in an oily and non-aqueous liquid catching, non-woven, water repelling cloth which is incorporated into an envelope of a hydrophobic synthetic resin fiber fabric, the envelope with cloth being partitioned in a number of tracks, collecting the enveloped liquid catching cloth with absorbed drip-liquids, washing the collected envelope liquid catching cloth in a solvent for the drip liquid, separating the drip liquid from the solvent, and incinerating the separated drip liquids with power generation.
Claim 2
Dependent Claim
91 words
A process for catching and processing non-aqueous drip-liquids, in which the drip-liquids to be processed are caught in an oily and non-aqueous liquid catching, non-woven, water repelling cloth which is incorporated into an envelope of a hydrophobic synthetic resin fiber fabric, the envelope with cloth being partitioned in a number of tracks, collecting the enveloped liquid catching cloth with absorbed drip-liquids, washing the collected envelope liquid catching cloth in a solvent for the drip liquid, separating the drip liquid from the solvent, and incinerating the separated drip liquids with power generation.
Claim 3
Dependent Claim
28 words
The process of claim 1 in which the process is repeated at least once using the enveloped liquid catching cloth after it has been washed with the solvent.
Claim 4
Dependent Claim
41 words
A cloth for use in the process according to claim 1, comprising an oily and non-aqueous liquid catching, non-woven, water repelling cloth enveloped by a hydrophobic synthetic resin fiber fabric, the envelope with cloth being partitioned in a number of tracks.
Claim 5
Dependent Claim
13 words
Cloth according to claim 3 in which the hydrophobic synthetic resin is polypropylene.
Claim 6
Dependent Claim
28 words
Cloth according to claim 4 in which the envelope with cloth is partitioned by a synthetic resin yarn stitched through the combination of envelope and liquid catching cloth.
Claim 7
Dependent Claim
28 words
Cloth according to claim 5 wherein the fiber fabric is 1/1 fabric of fibers dtext 1100 and the synthetic resin yarn is 100% polyester #100 continuous sewing thread.
