A method and system for removing hydrocarbon deposits from a heat exchanger tube bundle using an organic solvent. After contact with a heat exchanger tube bundle, the contaminated organic solvent may be treated to remove solids, base waters, and/or suspended hydrocarbons, and then again contacted with a heat exchanger tube bundle for the removal of hydrocarbon deposits. This allows for the removal of hydrocarbon deposits from a heat exchanger tube bundle in an efficient and environmentally friendly manner. The treatment of the heat exchanger tube bundle is also preferably performed using a method and system by which, through contact of the heat exchanger tube bundle with an organic solvent, a large percentage of hydrocarbon deposits are removed from the heat exchanger tube bundle in a short period of time.

A clean-in-place process may begin with a pre-rinse step in which soil (e.g., contaminants, residual product) is flushed from industrial equipment prior to circulating a cleaning agent through the equipment. To determine when the equipment has been suitably flushed, pre-rinse fluid exiting the industrial equipment and containing soil may be fluorometrically analyzed. A concentration of the soil is determined from fluorescent emissions emitted by the soil itself. Based on this information, the pre-rinse flushing process can be controlled, for example, to minimize water usage, maximize pre-rinse cleaning, or based on any other suitable metric.

A method for cleaning piping including the steps of supplying an acid to a cleaning water to prepare a cleaning water having pH of 4 or lower, mixing ozone gas to the cleaning water, and passing the cleaning water through the piping to be cleaned, or a cleaning system for piping, the system including a reservoir which retains cleaning water, an acid providing means supplies an acid to the cleaning water, an ozone generation means which generates ozone gas, a circulation flow path including a circulation pump which connects the reservoir and the ozone generation means in the form of a closed circuit, and circulates the cleaning water between the reservoir and ozone generation means, a conduction flow path including a conveying pump which communicates the reservoir and the piping to be cleaned, and conveys the cleaning water retained in the reservoir through the piping to be cleaned.

A medical instrument with an elongated outer housing and inner drive shaft and including an instrument flushing system that enables the medical instrument to be effectively cleaned after use is disclosed. The medical instrument may be configured such that the instrument flushing system receives a flushing fluid through a port at a proximal end of the instrument and directs the flushing fluid through a flushing fluid plenum created between an inner surface of the elongated outer housing and an outer surface of the inner drive shaft. The flushing fluid plenum may be maintained by a standoff formed from a collar with one or more axially extending grooves. The instrument flushing system may include a seal to seal portions of a drive system in communication with the inner drive shaft and extending radially outward from a main body of the medical instrument.
