Abstract

DC60 (13/03/45) Process and attachment The gaseous and gaseous mixtures are obtained with this attachment attachment. Movement invention And equipment fixtures, cryogenic separation equipment of natural gas elements Under pressure (14) with the first phase separator (B1), the elements of each phase Part of the gaseous portion (5) exiting the top (C1) is circulated back to the last floor of the tower. The movement is also included as an addition. Branching (9) from part of the first part, the top of the tower (3) exiting from the phase separator First machine The movement also included more than that. To the first separation, the bottom (4) of the tower from the first separator In the second separator (B2), other methods of achieving this effect are also described, see Figure 1, process and appendages, apparatus for separating the obtained gas and gas mixtures. The installation of this equipment Movement invention And equipment fixtures, cryogenic separation equipment of natural gas elements Under pressure (14) with the first phase separator (B1), the elements of each phase Part of the gaseous portion (5) exiting the tower (C1) is circulated back to the last floor of the tower. The movement is also included as an addition. Branching (9) from part of the first part, the top of the tower (3) exiting from the phase separator First machine The movement also included more than that. To the first separation of the tower (4) from the first separator In the second splitter (B2), other methods of achieving this effect are also described, see Figure 1.

Claims (2)

Claims (all) that will not appear on the advertisement page: 1. The process of lifting the cold mixture under pressure with methane and higher C2 and hydrocarbons is the lighter part. Rich in methane With the heavier end, rich in C2 and higher hydrocarbons. The process consists of In the first layer Mixtures that cool under pressure Will be lifted in the first holding tank It is part of the peak, quite easily evaporates. With the first part of the buttocks Relatively little volatile Take part one The part of the buttocks enters the central part of the spear, shaking the portion sequence. Collect heavier parts rich in C2 and higher hydrocarbons. It is the second part of the buttocks. In the lower part of the distillation tower. Take one part of the peak after reducing the pressure in the turbine. Enter the upper part of the distillation tower, the second part of the methane-rich peak. In the upper part of the tower The second portion of the apex is compressed and cooled to obtain a lighter portion. And one part of the sample is taken from the light part in the second, the first part of the cooled and liquefied sample. In the upper part of the spear In the third layer, the first part is directed through the sub layer. Including heat Passed through the second reservoir, forming a third part, relatively volatile peak. And the bottom third is relatively less volatile, the bottom third is directed to the central part of the distillation tower. The third part After being cooled and liquid The second part of the sample from the first part of the upper part of the sample is cooled and then the second part of the sample is taken. liquid And go to the upper part of the distillation tower, No. 3. The process of claim 2, which includes the second part of the sample is cooled and Partially controlled It is then lifted in the third retention tank to the fourth, relatively volatile peaks, and the fourth peak is cooled. And liquid To the upper part of the distillation tower The fourth part at the bottom. Relatively little volatile It is heated and then in the fourth tank. Is the fifth part of the summit Relatively volatile, the fifth at the top is heated. And sent to the bottom part of the second tank. 4. Process according to claim 3, where the upper part of the part sequence distillation tower is also composed. At least two consecutive layers In which the first floor is the lowest And the fifth part of the episode will be taken over. The first layer of the two contiguous tiers 5. The process of claim 3, where the upper part of the sectional distillation tower consists of At least three consecutive floors The first floor is the lowest And bring the fourth part of the top to the top of the second 6. The process of claim 2, where the upper part of the distillation tower consists of: At least three consecutive floors The first floor is the lowest And bring the fourth part of the top to siding on the second step of Two contiguous tiers 7. Procedure according to claim 6, where the third part of the top is taken to the first floor of the upper part. Section 8. Process according to claim 1, where the lower part of the distillation tower. The floor connected together with the example of the new infiltration device 9. Method according to claim 1, where the second part of the peak is heated and condensed after It is evaporated from the distillation fraction. To obtain a light portion rich in methane 1 0. Process according to claim 1, where the upper part of the sectional distillation tower contains At least three layers The first floor is the lowest And part of the sample was placed in the lower part of the last floor, and the top three was taken under the last floor 1. 1. Process according to claim 1, where the central part of the distillation tower, part sequence consists of At least two consecutive layers The first level is the lowest. And the third part of the bow was brought into the first floor. Of two consecutive layers And the first part, the top was imported, the upper part of the first floor 1 2. Equipment for lifting cold mixes under pressures containing higher methane and C2 and hydrocarbons. Is the best part Rich in methane With the heavier, rich in C2 and higher hydrocarbons, composed in the first layer Including part distillation tower The cold mix under pressure means the mixture is lifted in the first holding tank. It is part of the top episode. Relatively easily evaporates With the first part of the buttocks is somewhat less volatile The bottom part is imported into the central part of the hierarchical distillation tower, the heavier end part, rich in and the higher hydrocarbons, is deposited as the second part of the bottom in the lower six. After the first part pressure is reduced in the turbine. The first part of the upper part is imported to the upper part of the tower. Distillation The second part of the episode. Rich in methane Will be collected in the upper part of the distillation tower. And the second part of the episode will be Compress and cool to get a light portion. And the first part of the sample is from the light section. The second layer means the first part and the sample is taken to the upper part of the sequence distillation tower.
