Abstract
A method and a system for purification of oil, wherein the method comprises the steps of:—adding to a contaminated oil provided in a preparation tank a chemical booster for boosting capturing of impurities and/or a separation of phases in the contaminated oil;—waiting for allowing different phases to be separated;—pumping content out from the preparation tank through a fluid connection; sensing at least one property of the content in the fluid connection;—controlling a valve provided in the fluid connection to transfer the content to a next step in the purification process or to another destination in dependence of the sensed at least one property.
Claims10
A method for purification of oil comprising the steps of:
- adding to a contaminated oil provided in a preparation tank a chemical booster for boosting capturing of impurities and/or a separation of phases in the contaminated oil;
- waiting for allowing different phases to be separated;
- pumping content out from the preparation tank through a fluid connection;
- sensing at least one property of the content in the fluid connection;
- controlling a valve provided in the fluid connection to transfer the content to a next step in the purification process or to another destination in dependence of the sensed at least one property;
- and
- controlling said valve to only transfer the content to the next step of the purification process if the sensed at least one property corresponds to an oil content above a predefined threshold.
(canceled)
A system for purification of oil, said system comprising;
- at least one preparation tank in which a contaminated oil and a chemical booster for boosting capturing of impurities and/or separation of phases in the contaminated oil is provided;
- at least one centrifugal separator;
- a fluid connection allowing transfer of content out from the preparation tank;
- and
- at least one redirection arrangement provided in the fluid connection, said redirection arrangement comprising a valve which is arranged to direct the content from the preparation tank to either the centrifugal separator, possibly via another tank, or to another destination, said redirection arrangement further comprising at least one sensor and a control system connected to the at least one sensor and to the valve,
- wherein said control system is arranged for controlling said valve to transfer said content to the centrifugal separator or to the other destination in dependence of an output from the at least one sensor, and
- the control system is arranged to control said valve to only transfer the content to the centrifugal separator if the output from the at least one sensor corresponds to an oil content above a predefined threshold.
