Title: Extractive distillation of aromatic hydrocarbons with a  sulpholanetype solvent
IPC: C10G7/10
Filed: 1970-12-21
Abstract: 1333039 Distilling hydrocarbons UNIVERSAL OIL PRODUCTS CO 21 Dec 1970 60467/70 Heading C5E Aromatic hydrocarbons are extracted and recovered from their mixtures with non- aromatic hydrocarbons by the use of a solvent of the sulpholane type by (i) introducing the mixture into an intermediate point of an extractive-distillation column, (ii) introducing lean solvent into the upper section of the column, (iii) withdrawing from the bottom of the column an extract stream of solvent with aromatic hydrocarbons dissolved in it, (iv) withdrawing from the top of the column a raffinate stream of non-aromatic hydrocarbons contaminated by solvent, (v) washing at least part of the raffinate stream with water to remove solvent, (vi) fractionating the extract stream to obtain a distillate of aromatic hydrocarbons and water and a bottoms fraction of lean solvent, and (vii) introducing the wash-water containing solvent from step (v) into the distillation column of step (i). Solvents referred to are sulpholane, its alkyl-, alkoxy- and aralkyl-substituted derivatives, 2-sulpholene, 3-sulpholene, methyl 2-sulpholyl ether and 2-sulpholyl acetate. The first distillation may be at a pressure from atmospheric to 7À8 atm., the second at 100- 400 mm.Hg. absolute. As shown, a mixture of aromatic and non-aromatic hydrocarbons, e.g. that obtained from a catalytic reforming unit, is supplied to a still 11 by line 10, and solvent is supplied by line 12. Raffinate, taken off by line 16, is condensed at 17, separated from an aqueous phase at 19, washed with water at 22 and leaves the system by line 24. Of the solvent and extract leaving the bottom of the still, part is reheated at 15 and returned to the still, and the remainder passes by line 13 to a second still 27, where extract is stripped from the solvent by steam admitted by line 36. The extract, taken off by line 28 is condensed at 29, and separated into three phases at 31, of which a gas leaves by line 32, and aromatic hydrocarbons by line 33, while the aqueous layer is recycled by line 23. Of the solvent leaving the bottom of the second still, part is reheated at 38 and returned to the still, and the remainder passes by line 12 and heat-exchangers 35 and 26 to the first still; make-up solvent enters the system by line 39. Of the aqueous layer from the accumulator 31, part passes through lines 34, and 36 and heat-exchanger 35 to the second still; make-up steam enters the system by line 40. The remainder of this aqueous layer passes by line 23 to the washing column 22, where it serves to wash the raffinate. The water leaving this column, and the aqueous phase from the separator 19 pass by line 25 and heat-exchanger 26 to the first still which thus serves also to separate the solvent from the wash water.

Title: Nonlinear oscillation circuit for proximity switch
Inventor: HISANAGA TETSUO
IPC: H03K17/95
Filed: 1991-02-06
Abstract: PURPOSE:To obtain a desired detection characteristic by forming a high frequency oscillating circuit with two amplifiers for large amplitude and small amplitude, limiting the output of the amplifier with a small amplitude so as to detect the oscillated amplitude level. CONSTITUTION:The oscillating signal amplitude is increased as an object to be detected is parted from a detection coil L1, a collector current of a transistor(TR) Q18 is chanted when a prescribed distance is exceeded, as the collector current of the TR Q9 is started for limit, the current is decreasing and the oscillating signal amplitude is kept to a value equivalent to a reference voltage of a comparator 5. A TR Q6 is turned on for a positive half cycle of the oscillating wave and a positive feedback current flows to the coil L1 and a capacitor C1 through TRs Q4, Q5. When the parting distance with respect to the coil L1 is increased and the oscillating amplitude exceeds a prescribed voltage, the feedback current of an amplifier 2 for a large amplitude contributes to the oscillation and the oscillating amplitude is increased. Thus, since the circuit copes with various coils in which the loss characteristic with respect to the distance between the body to be detected and a proximity switch differs, a desired detection characteristic is realized.
