Patent NL-7804750-A (NL)
IPC: F04D27/02
Filed: 1978-05-03
Abstract: The control system of the invention regulates a centrifugal compressor having inlet guide vanes adjustable as one means for varying the compressor capacity.  A variable speed motor is connected to drive the compressor, and provides another means for regulating the compressor capacity.  The control system regulates the motor speed alone over one portion of the load variation curve, and regulates the motor speed jointly with the inlet guide vane opening over another portion of the load variation curve, to achieve the most energy-efficient operating condition while avoiding the surge condition.  This optimum control path is realized by utilizing a signal which is a measure of the compressor head value.  Compressor surge or instability is avoided by deriving a critical Mach number (speed indication) for any given operating condition, as a function of the compressor head and vane position, and preventing the motor speed from going below that Mach number under the specific operating conditions. The control system of the invention is useful both with existing equipment, by way of retrofit, and with newly manufactured and installed equipment.

Title: Contact mass-exchange apparatus
Inventor: NIKOLOV NIKOLAJ
IPC: B01D11/04
Filed: 2003-11-14
Abstract: The contact mass-exchange apparatus ensures highly effective mass exchange between two non-miscible fluids without being dispersed in each other. The problem of the non-dispersion mass exchange apparatus has been solved, wherein the boundary layer between the contacting fluids is passively refreshed due to the natural viscose friction between them, wherein the intensity of the mass exchange along the length of the bunch of fibres is also reduced. According to the invention fibres (3) are flattened periodically along their lengths, so that their cross sections form a series of circles and ovals, thus ensuring multiple local changes of the direction and size of movement of the fluids along the length of the fibres, resulting to an exchange (refreshing) of the fluid layer. The continuous refreshing of the fluids in their contact surfaces ensures evening of the rate of occurrence of the mass exchange along the lengths of the bunch, thus increase to twofold the efficiency of the performance of the mass-exchange apparatus. It comprises a contactor tube (4) and vessel for fluid separation (6). Contactor (4) is in the form of a cylinder (tube) filled by multiple fine metal fibres (3) packed together in a bunch. In the upper end of contactor (4) both fluids are fed, so that one of them to "wet" firbres (3) and continue its motion along their surfaces in the form of a film, and the other fluid shall be moving in the bunch between the "wetted" fibres (3) from the first fluid. In the lower end of contactor (4) both fluids are fed to a separation vessel (6) for the realization of their complete stratification and cleaning.
