A method and a device (50) for removing fragments and/or particles from containers, such as in particular glass tubes (5), provides means for adjusting the electrostatic force (40) in the tubes (5) and means for removing (60) of the fragments. The means for removing (60) can comprise a jet of fluid, of measured speed, put in the containers (5) by a nozzle (2), whereas the means for adjusting the electrostatic force (40) can comprise an element (1) for putting an electrically conducting fluid (8) with a measured resistivity in the containers (5). This way, the fluid (8), for example ionized air, acts in order to reduce and/or eliminate the electrostatic charge, and therefore the electrostatic force, between the fragments (30) and the surface of the containers, assisting the removal by means of jets of fluid or by suction means.

A nozzle cleaning period management device is provided with a cleaning device that cleans suction nozzles that are used in order to perform vacuum retention of an electronic component, a flow rate measurement device for measuring a flow rate that flows through the suction nozzles, a reduction amount calculation device for calculating a unit flow rate reduction amount of the flow rate of the suction nozzle per a number of times of mounting of electronic components on the basis of a flow rate difference before and after cleaning, which is measured by the flow rate measurement device, and an estimation device for estimating a cleaning period, which subsequently cleans the suction nozzles, on the basis of the unit flow rate reduction amount, which is calculated by the reduction amount calculation device, and a flow rate after cleaning.

The present invention regards a manifold for use in a flow system, comprising a longitudinal main pipe section (1) with one inlet (13) connectable to a feed pipe (9) and at least two outlets (14) arranged in a row along the main pipe section (1), where a center axis (15) of the main pipe section (1) during normal use extends in a mainly horizontal direction. The outlets (14) are arranged in a lower half of the main pipe section (1) and connected to outlet pipe sections (22) arranged with a center axis (21) extending with an downward angle from the main pipe section (1). The invention also regards a method for distributing a mixed flow into several pipes and a method for cooling a multiphase fluid.

Embodiments of the present disclosure provide a purging system for a turbine fracturing apparatus group and a turbine fracturing apparatus group. The turbine fracturing apparatus group includes a plurality of gas turbines, each gas turbine includes a plurality of fuel supply pipelines. The purging system includes: a first air compressor and a purging pipeline, the purging pipeline communicates the first air compressor with the plurality of fuel supply pipelines of each gas turbine in the turbine fracturing apparatus group, and the first air compressor is configured to, in a case where at least part of the plurality of fuel supply pipelines is stopped from supplying fuel, supply compressed air to the at least part of the plurality of fuel supply pipelines which has been stopped from supplying fuel, so as to perform purging.

Methods are disclosed for handling cylindrical tubulars in a process that, in preferred embodiments, also performs cleaning, inspection and other operations on the tubular. The tubular is held stationary while it is rotated. During rotation of the tubular, internal and external cleaning systems, and data acquisition systems, pass up and down the length of the rotating tubular. In preferred embodiments, a first tubular is loaded onto the handling machine, whereupon it is indexed and then rotated. Cleaning, inspection and other operations may be performed during rotation. Once operations are complete, the handling system ejects the first tubular while queuing up a second tubular to be loaded.

Provided is a method for removing deposited solid residue from equipment used in the processing of (meth)acrylic acid or esters, including the steps of dissolving the solid residue in a cleaning solution comprising an organic carboxylic acid to produce a solid residue slurry; and removing the solid residue slurry from the equipment.

An oxy-acetylene cutting torch tip cleaner includes an elongated body portion with at least one actuator and at least one associated housing bore for storing a cleaning pin. Each cleaning pin is coupled to an actuator movable from a first position with the cleaning pin contained in the housing bore to a second position with the cleaning pin extending from the housing bore, for abrading and cleaning the cutting torch tip. Each actuator, coupled to its cleaning pin with a slider, is biased to the first position and a lock engages each actuator in the second position such that when the lock is disengaged from the actuator at the second position with the cleaning tip extended from the body, the actuator automatically returns to the first position thereby retracting the cleaning pin back into the housing bore.

The present invention comprises a method and system for the in-situ cleaning of a heat exchanger tube bundle of carbonaceous deposits. Using the method and system, an organic solvent is brought into fluid communication with one or more heat exchanger tube bundles in a closed system. The closed system is formed at the site of operation of the heat exchanger tube bundles and without having to remove the heat exchanger tube bundles from their shells or other associated equipment. Once the closed system is formed, the organic solvent is brought to a temperature at which it is effective to remove carbonaceous deposits from the heat exchanger tube bundle and flowed through the equipment associated with the heat exchanger tube bundles so as to contact the heat exchanger tube bundles and remove carbonaceous deposits that have formed therein. In some embodiments, the spent organic solvent may be recovered, such as through the removal of suspended hydrocarbons, and reused in the method and system for cleaning heat exchanger tube bundles.
