Patent number: 9625055Abstract: The invention relates to a throttling valve comprising a fluid inlet (29) and a fluid outlet (27). The throttling valve is arranged to control a flux of a fluid stream flowing via a flow path from the fluid inlet (29) to the fluid outlet (27). The flow path comprises a plurality of openings (330) which, in use, create a pressure reduction over the throttling valve and thereby a cooling effect of the fluid. The openings (330) widen in a downstream direction.Type: GrantFiled: July 30, 2009Date of Patent: April 18, 2017Assignee: TWISTER B.V.Inventors: Max Robert Anthony Ter Haar, Zvonimir Opic, Marco Betting, Cornelis Antonie Tjeenk Willink

Patent number: 8226743Abstract: The invention relates to fluid separator comprising:—a throat portion (4) which is arranged between a converging fluid inlet section and a diverging fluid outlet section, the diverging fluid outlet section comprising an inner primary outlet (7) for condensables depleted fluid components and an outer secondary outlet for condensables enriched fluid components (6); and—a central body (10) provided upstream of the throat portion (4) in the fluid inlet section, the central body (10) being arranged substantially coaxial to a central axis I of the fluid separator. The fluid separator is arranged to facilitate a main flow through the converging fluid inlet section, the throat portion towards the diverging fluid outlet section. The central body (10) comprises an outlet (13), directed towards the tubular throat portion (4) and is arranged to add a central flow towards the throat portion (4).Type: GrantFiled: March 26, 2008Date of Patent: July 24, 2012Assignee: Twister, B.V.Inventors: Marco Betting, Cornelis Antonie Tjeenk Willink, Bart Prast, Zvonimir Opic
