摘要： Una planta para la produccion de hidrato de gas natural que comprende tres etapas (i), (ii) y (iii). La etapa (i) comprende tres recipientes a presion (A1, A2, y A3), la etapa (ii) comprende dos recipientes a presion (A4 y A5) y la etapa (iii) comprende un recipiente a presion (A6). Las condiciones de temperatura y de presion en el recipiente a presion son tales que el hidrato de gas se forma en los recipientes. El hidrato formado es llevado a través de la tuberías (e1, e2, e3, e4, e5 y e6) a partir de los recipientes a presion hasta un distribuidor (34). El agua fría que es tanto el agua reactante como el enfriador del proceso, se provee mediante los medios enfriadores (20) y se suministra simultáneamente a la parte inferior de cada tubería del recipiente a presion (22), el distribuidor (32) y las tuberías (b1, b2, b3, b4, b5 y b6). El gas natural proveniente del suministro (26) es alimentado mediante el conducto (30), el distribuidor (32) y las tuberías (c1, c2 y c3) a las boquillas en la parte inferior de cada recipiente (A1, A2 y A3), en cuyas boquillas las burbujas de gas ascienden a través de las columnas de agua en los recipientes (A1, A2 y A3). El gas sin reaccionar es alimentado desde los recipientes (A1, A2 y A3) a boquillas similares en los recipientes (A4 y A5) desde los cuales se alimenta el gas sin reaccionar a una boquilla en el recipiente (A6) en el cual se lleva el gas sin reaccionar a través del conducto (d6). La velocidad superficial media ascendente del gas es substancialmente la misma en las tres etapas.

摘要： A method and apparatus for the liquefaction of a gas, more particullarly oxygen, starting from a stream of the gas under pressure. In the case of oxygen, the oxygen stream under pressure may conveniently be obtained following electrolysis of water under pressure and hydrogen may be liquefied in parallel with the oxygen so producing supplies of liquid hydrogen and oxygen in any desired proportions e.g. the proportions required in aerospace applications. The gas stream is divided into a product stream and a refrigeration stream which is expanded to low pressure in stages to provide return cooling flows against which either directly or indirectly via an inert buffer coolant, the product stream is cooled down to approximately the liquifying temperature.

摘要： In the liquefaction of a permanent gas comprising nitrogen the temperature of a permanent gas stream at a pressure in the range of 75 to 90 atmospheres is reduced to below its critical temperature by passage through heat exchangers 10, 12 and 14. Providing at least part of the necessary refrigeration, a single nitrogen working fluid cycle 36 is performed in which the nitrogen working fluid is compressed to a pressure in the range of 75 to 90 atmospheres, cooled to a temperature in the range of 170 to 200 K, work expanded in expansion turbine 38 to a temperature in the range of 107 to 120 K, and warmed by heat exchange countercurrently to the permanent gas stream, thereby providing refrigeration for the permanent gas stream.

摘要： A stream of compressed nitrogen (or methane) at above its critical pressure is passed along conduit l0 through heat exchangers l6, l8, 20, 22 and 24, in sequence, to cool it to below its critical temperature. The resulting fluid is then subjected to expansion and resultant liquid is collected. Refrigeration for the heat exchangers is provided by nitrogen working fluid cycles 62, 72 and 82 employing expansion turbines 64, 74 and 84 respectively. The turbines have different inlet temperatures but substantially the same outlet temperature.

摘要： A method for condensation of a gas with several fractions, e.g. gas from the tank compartment in an oil tanker during loading. The gas is supplied to a first heat exchanger (4) and cooled therein by means of a coolant. Condensed and non-condensed gas fractions are supplied separately from the heat exchanger (4). For further exploitation of the cooled, non-condensed gas fractions, these and an additional gas are passed separately from the tank compartment to a second heat exchanger (30) where the non-condensed fractions cool the gas and cause condensation of its fractions with a condensation temperature which is less than the temperature of the non-condensed gas fractions from the first heat exchanger.

摘要： A helium cooling apparatus (l) according to the present invention comprises a refrigerator (2) for cooling a refrigerant. The refrigerator (2l) is connected with the proximal end of a transfer line (23), which is used to transport the refrigerant. A port (l8) with a predetermined diameter is formed in a liquid-helium container (ll) which contains liquid helium. A condensation-heat exchanger (24), which is connected to the distal end of the transfer line (23), is inserted into the liquid-helium container (ll) through the port (l8). A heat-transfer surface of the heat exchanger (24) is formed with a plurality of grooves (50) extending in the gravitational direction. The refrigerant is evaporated in the heat exchanger (24), and condensed liquid helium, adhering to the heat-transfer surface, drops along the grooves (50) when helium gas in the liquid-helium container is cooled to be recondensed. Accordingly, the heat-transfer surface cannot be covered with the condensed liquid helium, so that a wide heat-transfer area can be secured. Thus, the heat transfer coefficient of the heat exchanger (24) is improved considerably. In this arrangement, therefore, the port (l8) of the liquid-helium container (ll), through which the exchanger (24) is inserted into the container (ll), need not have a large diameter.
