A preferred embodiment is a cryogenic fluid is carbon dioxide, and the system parameters are set at the low temperature refrigerant fluid in or near the outlet surface of the expansion member into the solid phase, and in the form of fine snow from the spray outlet surface out.L·思马斯...
Liquefied gases are used in a wide range of applications, including metal processing, medical technology, electronics, water treatment, energy generation and the food industry. Today, more and more of these industrial gases are being delivered to customers in liquid form at cryogenic te...
form. These fractures may be effective in increasing the permeability of the formation, and may bypass wellbore damage such as skin damage in the near wellbore area. In some instances a proppant such as natural sand, or engineered products such as coated sand or sintered bauxite may be used....
(solid carbon dioxide) vaporizes atatmospheric pressureto form gaseouscarbon dioxidebecause the triple-point pressure for carbon dioxide is greater than atmospheric pressure. LineTMis themelting curve and represents anequilibriumbetween solid and liquid; when this curve is crossed from left to right, ...
Submarine venting of liquid carbon dioxide on a Mariana Arc volcano Although CO2 is generally the most abundant dissolved gas found in submarine hydrothermal fluids, it is rarely found in the form of CO2 John,Lupton - 《Geochemistry Geophysics Geosystems》 被引量: 159发表: 2006年 Venting of a ...
The oxalic acid aqueous solution which it fills up in the electrolytic tank electrolyzing with the electrolysis device, as it generates carbon dioxide, operating the ultra wave the air bubble of the carbon dioxide which occurs with the ultrasonic supply system, it can form the minute air bubble...
The hydrogen is combined with carbon dioxide to form methanol [74]. Due to the high exothermicity, methanol synthesis reactor system is operated at a pressure of 70 bar and a temperature of 250 °C [68]. In commercial process, the produced heat is often utilized to produce electricity for...
[108] used a working pair of carbon dioxide–propylene as working fluid, which could increase the COP by 5.9%. Based on Maurer's trans-critical refrigeration system with a vortex tube replacing an expansion valve, they designed a cascade system in which a cascade heat exchanger was used ...
geothermal heat produced by radiogenic elements. They find that subglacial oceans or lakes of liquid water can form by basal melting and persist under ice sheets on Earth-sized exoplanets even for surface temperatures as low as 200 K expected e.g. on Trappist-1g. Under the weight of high-...
Under the impact pressure of the high-pressure gas, the medium around the release hole generates a compressive stress wave, which propagates outward in the form of a cylindrical wave. Because the peak value of the stress wave produced by the liquid carbon dioxide phase transition is small, ...
