Abstract
Disclosed in the present invention is a system and method for supplying acetylene to an apparatus using acetylene, the system having at least one acetylene storage apparatus and an acetylene content analysis apparatus. The system and method disclosed in the present invention can utilize the capacity of an acetylene cylinder to a higher degree; before the solvent impurity concentration in acetylene gas reaches a level where it is no longer suitable, a more accurate understanding of the usable acetylene amount in the acetylene storage apparatus can be gained through detection, thereby reducing the number of times that the acetylene storage apparatus is refilled and replaced, and lowering the user's total costs.
Claims8
A system for supplying acetylene to an apparatus that uses acetylene, comprising:
- at least one acetylene storage apparatus, for supplying a feedstock comprising acetylene and a solvent to an apparatus that uses acetylene;
- and
- an acetylene content analysis apparatus, comprising an analytical instrument and a data processing component;
- at least one pressure regulating valve is provided upstream of the apparatus using acetylene, for controlling the switching of each acetylene storage apparatus;
- wherein the analytical instrument comprises gas chromatography with a thermal conductivity detector or a flame ionization detector or Fourier-transform infrared spectroscopy, and is used to detect a solvent concentration in the feedstock;
- wherein the data processing component is configured to analyse the solvent concentration from the analytical instrument as time passes, compare the solvent concentration analysis with a preset value of solvent concentration, and output a control result;
- and
- wherein the control result outputted by the data processing component comprises the opening/closing of each pressure regulating valve.
A method for supplying acetylene to an apparatus using acetylene, comprising:
- (1) providing at least one acetylene storage apparatus, for supplying a feedstock comprising acetylene and a solvent to the apparatus using acetylene;
- (2) arranging an acetylene content analysis apparatus, a pressure regulating valve and a control valve upstream of the apparatus using acetylene, the acetylene content analysis apparatus comprising an analytical instrument and a data processing component, the pressure regulating valve being used to control switching of each acetylene storage apparatus, and the control valve being used to control the delivery of the feedstock to the acetylene content analysis apparatus;
- the analytical instrument detecting a solvent concentration in the feedstock and transmitting same to the data processing component, and the data processing component controlling the pressure regulating valve, to switch each acetylene storage apparatus.
