A liquid chromatograph includes at least one mobile phase supply flow path (6; 42), at least one cleaning solution supply flow path (8; 44) joining the mobile phase supply flow path (6; 42), an analysis flow path (4) provided with a separation column (14), a sampling flow path (2) provided, at a tip end thereof, with a sampling needle (12), a switcher (10; 26) including a high-pressure valve (10) having an injection port (16) and configured to switch a flow path configuration of the liquid chromatograph between a loading state in which the analysis mobile phase supply flow path (6) and the analysis flow path (4) are connected in a fluid manner without the sampling flow path (2) and an injecting state in which the sampling flow path (2) is interposed between the analysis mobile phase supply flow path (6) and the analysis flow path (4) when a tip end of the needle (12) is inserted into the injection port (16), and a controller (50) configured to execute, when a predetermined condition is satisfied, the cleaning operation of supplying the mobile phase and the cleaning solution to the analysis flow path (4) and/or the sampling flow path (2) to temporally change the composition of liquid flowing in the analysis flow path (4) and/or the sampling flow path (2).

During meeting for planning operations for scale removal and scale inhibitor squeeze treatment in wells, the possibility of the manifold being partially incrusted with scale raised considering the more critical mixture of water produced. The proposed solution is a method of treatment for removing scale from a manifold. Said method uses the geothermal heating of the exploration reservoir to heat a chemical removal solution (50). Heating is required to ensure the temperature is in a range that is also suitable for conducting the removal reaction, since the distance that the solution travels to the manifold (20) e the low temperature of the underwater environment make the reaction occur inefficiently, as in the case of pre-salt.

The invention concerns a method of treating the pipes of the drinking water network of an aircraft for cleaning purposes, said network comprising at least one storage tank and a plurality of pipes providing a plurality of water inlet and outlet points, notable in that it involves the following operations: —injecting water at a high temperature of between fifty and one hundred degrees Celsius into the network, for treatment purposes, —draining, —injecting cold water at a temperature no higher than thirty degrees Celsius combined with chemical treatment products comprising a chlorinated product or hydrogen peroxide, —draining, —injecting water at a high temperature of between fifty and one hundred degrees Celsius for rinsing purposes, eliminating the chemical treatment products comprising a chlorinated product or hydrogen peroxide, —draining. Applications: cleaning the drinking water network of an aircraft.

A cleaning method for a heat exchanger is a cleaning method for a heat exchanger which includes a header passage and a plurality of internal passages connected to the header passage, that includes: a step of supplying a cleaning fluid, via the header passage, to some of the plurality of internal passages connected to the header passage, selectively.

A Clean-In-Place (CIP) control surveillance system has all streams forward and return monitored and accounted for, where values for each step may be stored in a data base. The CIP system used to clean one or more objects includes a primary tank for primary cleaning media, optionally a secondary tank for secondary cleaning media, a supply of freshwater, one or more forward lines, one or more return lines returning liquid, and valves directing the flow through tanks and pipes of the CIP Process Plant. The system further includes a sensors and transmitters measuring concentration in the forward line and return line and transmitting a value for the concentration to a controller, a sensor and transmitter measuring volume or mass flow in the forward line and return line, and a controller or computer configured to compare in and out values for a period.

A device for cleaning items comprises an enclosure defining a wash chamber, a rotor positioned within the wash chamber and selectively rotatable about an axle, a motor for selectively rotating the axle, a dispenser, and a drain. The rotor comprises a plurality of holders spaced about the axle and adapted to selectively receive and hold a respective item to be cleaned. The dispenser at least one liquid input and at least one liquid output and is positioned such that the at least one liquid output directs cleaning fluid at one of the items to clean material out of the cavities. The drain is for draining the cleaning fluid out of the chamber. The rotor is selectively rotatable at a predefined rotational speed for a predefined amount of time to expel cleaning fluid from the cavities of each item to be cleaned.

The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.
