摘要： Volatile compounds (“VCs”), especially volatile organic compounds (“VOCs”), are cryogenically removed from a process gas stream (pW) by cooling the gas stream in a condenser to condense the VC to form both liquid VC and VC ice and providing a treated process gas essentially freed of the VC but containing entrained VC ice particles, which are subsequently removed by passing the treated process gas through a filter downstream of the condenser to remove at least particles of a size greater than 50 &mgr;m. The condensation can be conducted in an indirect heat exchanger or by direct contact of the process gas with a liquid cryogen such as liquid nitrogen. It is preferred that the filter removes VC ice particles greater than 1 &mgr;m.

摘要： A method and apparatus are set forth for transferring a cryogenic fluid. A polymeric, coaxial (i.e. “tube-in-tube” geometry) transfer line is utilized where a first portion of the cryogenic fluid flows through the inner tube while a second portion flows through an annulus between the inner tube and outer tube which annulus is at a lower pressure than the inside tube. In one embodiment, the inner tube is substantially non-porous and the transfer line is preceded by a flow control means to distribute at least part of the first and second portions of the cryogenic fluid to the inner tube and annulus respectively. In a second embodiment, the inner tube is porous with respect to both gas permeation and liquid permeation such that both a gaseous part and a liquid part of the first portion permeates into the annulus to form at least a part of the second portion.

摘要： A cryogenic tunnel freezer (10) having modular design and construction including a lower section (16) that can be raised and lowered relative to an upper section (14), the upper and lower sections (14, 16) defining a tunnel (12) when the lower section (16) is in a closed (raised) position. Product is moved through the tunnel (12) via a belt (22) formed of arrays of plastic modules (76) that are reinforced by metal chains (140) and rods (150). The lower run (23) of the belt (22) rides on the floor (48) of the lower section (16) and the upper run (21) rides on the lower run (23) when the belt (22) is operated. The flow of cryogenic fluid through the tunnel (12) is aided by vaporization of a cryogenic fluid and baffles (98), but no air-moving devices located within the tunnel (12).

摘要： A method for determining the flow rate of a fluid, having a liquid fraction and a gas fraction, having the steps of: measuring the pressure and temperature of the fluid at a flow control device through which said cyrogenic fluid passes; inputting the measured pressure and Cv into an algorithm; and performing a single or multi-step iteration to determine a fluid mass flow rate of the fluid through the flow control device using the algorithm that relates the mass flow rate of the fluid to the Cv, and mass densities of the liquid fraction and the gas fraction of the fluid which are a function of the measured pressure, and temperature. A system is also provided.

摘要： A conical impact mill has a rotor assembly (1) in which impact elements (7) arranged in at least two axially spaced rows provide, or can be adjusted to provide, a grinding gap (a′, a″), defined between the impact elements and a right frustoconical grinding surface of the mill housing (2), that is not constant in the axial and/or circumferential direction of the rotor assembly. Impact elements can be fixedly or adjustably mounted in the rotor assembly and/or the rows can be mutually adjustable axially to change the grinding gap.
