A system and process for cleaning a vessel is described. In embodiments, the system has one or more manway adapters configured to fit one or more manways of the vessel and deliver a cleaning solution through them. Further, in embodiments the system includes one or more actuators which are configured to position the one or more manway adapters horizontally or vertically to allow for optimal alignment and positioning of the manway adapters within the manways. Movement of the manway adapters may be facilitated by way of a frame assembly mounted on one or more horizontal rails. The system may be used to clean tanks and other vessels such as those that are on tanker trucks, tanker cars, or frac tanks.

A cleaning solution for cleaning laboratory consumables comprises sodium percarbonate in a concentration of from 0.9% w/w to 1.6% w/w based on a total weight of the solution and at least one diluent to 100% w/w.

The disclosure relates to the cleaning of oilfield tools made of metal, particularly to the method of reclamation oilfield tools, already used in the mechanical deep-pumping extraction of oil, as well as to the product made with the help of the mentioned method. The method of remanufacturing of standard length rods includes cleaning the rod with at least one cryogen to eliminate environmental contamination and to assist in workplace safety.

The present application discloses a method for purge clean of a low pressure furnace, comprising: step 1, providing a process chamber of the low pressure furnace in a standby state, wherein an inner wall thin film formed by a furnace deposition process is accumulated on the surface of an inner wall of the process chamber; step 2, performing temperature ramp-up or temperature ramp-down treatment on the process chamber to generate first thermal stress in the inner wall thin film, wherein thin film particles with poor adhesion in the inner wall thin film peels off; step 3, introducing a cleaning gas in a pulse manner to perform cycle purge clean on the process chamber, so as to remove the peeling thin film particles from the process chamber; and step 4, switching a state of the process chamber to the standby state after the cycle purge clean ends.

Disclosed is a chemical exchange method in a liquid treating device including a first tank, a second tank, and a third tank, the method including: a flushing operation of draining chemicals received in the first tank, the second tank, and the third tank, injecting a flushing chemical into each tank and then circulating the flushing chemical, and then draining the flushing chemical; and a liquid exchange operation of supplying a new chemical to at least one of the first tank, the second tank, and the third tank to perform liquid exchange.

Certain booster compositions and methods of using the booster compositions to clean fermentation equipment are disclosed. The booster compositions are useful in environments with variable, changing, unstable, or limited alkalinity sources found within fermentation equipment.

Systems, assemblies, and methods to enhance extraction of pyrophoric materials from a refinery apparatus may include supplying a pressurized fluid to a plurality of vacuum generators, and generating, via the plurality of vacuum generators using the pressurized fluid, a vacuum flow. A manifold may provide a flow path for the vacuum flow, and pyrophoric material may be extracted from the refinery apparatus via the vacuum flow to a material collector through which the vacuum flow passes, depositing at least a portion of the extracted pyrophoric material in the material collector. One or more of inert gas or a cooling medium may be supplied to the material collector.

In a reaction system (1), a reactor (210) is provided in a sealed space covered by a blocking mechanism (111) and includes a supply port of a substance to be treated and a delivery port of a product. A conveyance apparatus (221) conveys the substance to be treated along an extending direction of a cylindrical body inside the cylindrical body. A fluid supply tube (204) is connected to a fluid inlet provided in the reactor and supplies a fluid for production. A fluid discharge tube (206) discharges a fluid inside the reactor from a fluid outlet provided in the reactor. A cleaning medium supply apparatus (232) branches and is connected to at least any one of the supply port or the fluid supply tube and can inject a cleaning medium in the reactor in a cleaning step.
