Title: Process for the separation of hydrogen cyanide from gases and waste gas
Inventor: FISCHER JOACHIM
IPC: C10L3/10
Filed: 1992-05-21
Granted: 1999-08-02
Abstract: The invention relates to a process for the separation of hydrogen cyanide from gases and exhaust gases by through-flow or circulation scrubbing, formaldehyde being added in a controlled manner to the aqueous scrubbing liquid for glycol nitrile formation; the control is carried out via the measurement of the HCN tension in a branched-off measurement stream, which is first treated with hydrogen peroxide in such a manner that after 1 to 100 seconds free H2O2 is still detectable, and is set to a constant pH prior to the HCN tension measurement. The process avoids a formaldehyde overdose which could not always be avoided in previously known processes having a control of the formaldehyde addition via the measurement of the cyanide-specific redox potential.

Granted: 2000-07-01
Abstract: PURPOSE: A method for forming a de-coupling capacitor is provided to achieve the capacitor having a large capacitance without using a separate area by forming the de-coupling capacitor on a field oxide layer. CONSTITUTION: A filed oxide layer(101) for defining a device forming area and a device isolation area is formed on a semiconductor substrate(100). Then, a gate electrode(1) is formed on the semiconductor substrate(100). Impurities are implanted into the semiconductor substrate(100) so that source/drain areas(3,4) are formed. Then, the first interlayer dielectric(5) is formed on the resulted structure. After forming a mask pattern for exposing a part of the source area(3) on the first interlayer dielectric(5), a contact hole is formed by etching the first interlayer dielectric(5). A de-coupling capacitor is formed on the field oxide layer(100). The de-coupling capacitor has the first electrode(7') connected to a power terminal, a dielectric layer(8) which covers the first electrode(7') and the second electrode(11) which is connected to a ground terminal.
