Pressurization system for high pressure processing system

Pressurization unit for use in processing equipment handling high pressure fluid, where the pressurization unit comprises at least one inlet and an outlet, the pressurization unit being adapted to receive a feed fluid at a feed pressure level at the inlet, being adapted to isolate the received feed fluid from the inlet and from the outlet and being adapted to increase the pressure of the fluid to a higher predetermined level and further being adapted to output the fluid through the outlet into the high pressure process while still isolated towards the inlet, the unit comprising an actuated valve at the inlet and an actuated valve at the outlet and further a pressurization device between the inlet valve and the outlet valve, where the inlet valve after having allowed inlet of a feed stream is closed for a period before the outlet valve is opened, hereby allowing pressure to be generated by the pressurization device and where the outlet valve is closed for a period before the inlet valve is opened, hereby allowing pressure to be reduced in the pressurization device, where a position indicator is provided indicating the cycle position of the pressurization device and being adapted to provide a control signal for opening and closing of at least one valve in the pressurization unit and further comprising a control system, where the control system is adapted to allow opening of the valves when a certain maximum pressure difference is present between either side of the valve to be opened.
