High-pressure reactor design control systems

The test equipment of crystal type of gas hydrates consists of a laser Raman spectrometer, gas supply system, jacketed cooling type high-pressure visual cell, temperature control system, data acquisition and other parts. The experiment using a laser Raman spectrometer for the JY Co. in French produced Lab RAM HR-800 type visible confocal Raman microscope spectrometer. Laboratory independently designed a cooled jacket visible in situ high-pressure reactor, reactor with sapphire window to ensure full transparency of laser, and high pressure performance, visual reactor effective volume 3 ml, compression 20 MPa effective volume, to achieve characteristics of gas hydrate non-destructive and accurate measurement. The schematic representation of equipment is shown in Eigure 1. 

The topic of handling liquids of different viscosities for dispersion processes in microfluidic networks with two microreactors ( droplet emitters ) is addressed by Unilever R D (Vlaardingen, The Netherlands) in a patent [14,15]. The patent deals with the flow distribution in a microfluidic network on the background of dispersion processes with two supply sources for the two phases, which supply via upstream channel systems two microfluidic reactors called drop emitters (Figure 22.6). The dispersion leaves the microreactors via downstream channels. The major point of the patent is that the flow distribution is controlled by a design which creates a high pressure drop in the upstream channels. The pressure drop in the downstream...
