Pilot and settlement studies whenever possible of use of the tubular turbulent device the design diffuser-konfuzornoy are conducted at an obessolivaniye of gas condensate. It is revealed that, from the point of view of small pressure difference on the ends of the device and efficiency of hashing, the relation of diameter of the diffuser to diameter of a confusor equal 2.0 is optimum. On the example of gas condensate of the Tolkyn field of the West of Kazakhstan it is shown that mixture of gas condensate with a small amount of fresh water (0.5 … 2% about.) in the tubular turbulent device allows to reduce the general content of salts from 95 g/m3 to 15 … 20 g/m3.
One of effective ways of target use of the high-boiling hydrocarbons of associated oil gas is their partial extraction by single absorption by stable oil. Distinctive feature in this process is prevalence of a gas phase. The conducted pilot and settlement studies have shown that at the relation of diameters equal 3.0 turbulization of mix on all length of the device with pressure difference less than 0.02 MPas is carried out. On installation of preparation of oil of the Rumayla field of the South of Iraq at a trailer step of separation at a temperature of 55 оC and pressure of 0.18 MPas about 0.84 t/hour of the associated oil gas directed to a torch are allocated. Use of the five-section tubular turbulent device and cooling of gas-liquid mix from 55 to 25 оC allows to reduce losses of hydrocarbons up to 40% of masses. Taking into account scaling it is recommended to use the five-section tubular turbulent device with diffuser-confusor design with a diameter of the diffuser of equal 240 mm, diameter of a confusor – 80 mm.
This paper describes the construction of information and measuring system for measuring large flows of gas. Proposed a structure of system that ensures invariance with respect to many disturbances in the flow and amount of gas. The sensitivity of measuring channels of metering, and offers advice on selecting differential pressure transducer.
The main directions for designing high-contact devices packed column apparatus. Presents three types of irregular attachments “Inzhehim”. Given the results of experimental studies on the hydrodynamic characteristics: pressure drop, fluid retention, limit load, back mixing. Made a compilation of experimental data in the form of calculated expressions. Provides a list of sites that use the attachments “Inzhehim”.
This paper shows the flow measurement system of gas without rate of expiration. The measurement system is built with using of elements of the theory of invariance in measurement devices and elements of the theory of partial flow meters.
