Description

The invention relates to the petrochemical and gas industries and can be used, in particular, in installations for the processing of gas condensates for the adsorption separation of hydrocarbon mixtures.

The purpose of the invention is to reduce the cost and capital costs.

Figure 1 shows an installation for adsorption and desorption (two process streams), a general view; on . figure 2 - upper distribution device, section; FIG. 3 shows a plant for adsorption processes with several process streams — 15, a general view.

Installation (figure 1) consists of two adsorbers 1, filled with a sorbentJ pipelines 2 and 3 adsorbers sv For installation with two adsorbers works as follows.

The adsorbers 1 and the internal truncated cones of both distribution devices connected to them by pipes 2 and 3 remain stationary, and the external truncated cones 5 rotate by means of an actuator 6.

During adsorption, process flow A through the opening 23 of the upper distributor to the torus, on the inner side of the inner cone 4, via channel 13 through opening 9 enters the annular groove 7. When the holes 9 and 19 are aligned, the channel 13 of the stationary cone 4 is connected to the canal 17 rotating cone 5 and the flow through this channel 17 through the opening 20 enters the channel 15 along with the upper and lower distributor-20 of the floating cone 4.. Then through the opening 24 through pipeline 2 the flow is directed to the adsorber 1 filled with the sorbent.

Pass the sorbent, technological flow 25 B through line 2 through the opening 24 of the lower distribution | Go device, channel 15, hole 20, channel 17 and hole 19 enters the annular groove 7. With simultaneous devices, each of which consists of coaxially arranged ternary inner fixed 4 and outer rotating 5 truncated cones. Distributing devices are connected with the drive 6. On the conical surface of the inner cone there are annular grooves 7 and 8, and holes 9 and 10 (figure 2), which

connected to the inlet 11 and the outlet 12 of the tech- nology of the holes 19 and 9, the flow along the canal flows by the channels 13,14 and 15, 16, located inside the fixed cone 4 and the channels 17 and 18, located inside the rotating cone 5. 35 holes 19-22, made on the inner surface of the rotating cone 5 and holes 23-26, located on the end side of the internal cone 4 facing the adsorbers.

To ensure continuity of work during adsorption processes with several process streams (for example, 4 streams), the installation is used (Fig. 3) with four adsorbers 1. At the same time, four annular grooves 7, 8, 27 and 28 are made on the inner cone and four holes 9 10, 29 and 30, which 50 provide adsorption processes.

The number of channels and holes on the rotating cone corresponds to annular grooves and openings of the stationary cone 4.

Lu 13 through the hole 23 out of the distributor.

During desorption, the regenerating stream B enters the adsorber from bottom to top through the lower distributor. The movement of process flows during desorption is similar to the movement of flows during adsorption.

When the outer cone 5 rotates, the sequence of adsorption and desorption operations repeats in both adsorbers. Various technological processes can be carried out in adsorbers, namely, drying, dewaxing, de-aromizing the process streams.

Based on specific conditions, different amounts of adsorbers are used. Depending on the increase in process flows, the number of annular grooves, channels and holes in the distributors accordingly increases.
