The present invention generally relates to corrosion management systems designed to deliver corrosion protection and/or the management of corrosion to a connector, a connection, a welded joint, or some other type of interface (e.g., a valve joint used to join to portions of piping). In another embodiment, the present invention relates to systems designed to deliver at least one form of corrosion, UV, salt spray, and/or fire damage protection, mitigation and/or the management to a connector, a connection, a welded joint, or some other type of interface (e.g., a flange used to join to portions of piping).

Northern Technologies International Corporation (NTIC), MN, in collaboration with Michigan State University (MSU), MI, pans to formulate and engineer chemically modified, marine biodegradable, biofiber-based, non-plastic waste bags that are water resistant, readily treatable with other organic wastes in the on-board waste processing equipment and marine biodegradable as defined by ASTM D7081 standard. As part of Phase I, NTIC investigated (1) three classes of biobased, non-plastic materials that function as a coating or as an adhesive depending on the manufacturing process employed; (2) coating of selected paper substrates using silylated soyabean oil to provide new biobased hybrid composite and (3) conducted aqueous biodegradability testing per ISO 14852. Phase I work was successful in coating soya-based non-plastic material onto different grades of unmodified paper to obtain a water-proof and grease-proof paper. Phase II will be directed toward scale-up and process development of coating paper in a large-scale manufacturing set up and convert the coated paper to bags. Development of such a high strength, water-proof, marine biodegradable, and non-plastic waste disposal bag will assist the fleet in reducing their at-sea plastic usage and significantly decrease the volume of plastic waste that must be processed and stored aboard. Furthermore, the newly developed technology would find application in traditional markets for coated paper such as disposable foodservice ware and trash bags.


The present invention generally relates to portable systems designed to deliver one or more corrosion inhibiting compounds to an enclosure, and to method for using same. More specifically, the present invention relates to portable, mobile, self-contained and/or discrete systems designed to deliver one or more corrosion inhibiting compounds to an enclosure while simultaneously purging and/or recycling the interior atmosphere of such an enclosure, and to methods for using same. In another embodiment, the present invention relates to portable systems designed to deliver one or more corrosion inhibiting compounds to an enclosure while simultaneously dehumidifying, purging and/or recycling the interior atmosphere of such an enclosure, and to methods for using same. Another aspect of the present invention is that the recycled atmosphere of the enclosure can be passed through an absorbent that removes and/or collects the volatilized metal corrosion inhibitor compound. The collected corrosion inhibitor can later be reused.

A method and apparatus for the corrosion protection of tank soil side bottoms is achieved by providing equipment to an existing storage tank as by installing a chime delivery system about the perimeter of the storage tank bottom plate, and introducing an appropriate amount of a corrosion inhibitor into the chime delivery system, whereby the corrosion inhibitor is readily admitted into the spaces between the substrate and the tank bottom plate. The system avoids any refurbishment of the tank and allows for easy introduction and replenishment of inhibitor without interruption of tank operations. The system also does not require any renovation of the tank, and does not require any replacement of the tank bottom plate panels.

Hydrogen is produced from methanol and water under supercritical temperature and pressure conditions desirably without any catalyst. The hydrogen can be produced in situ on an internal combustion engine using a heat source such as the exhaust system of the internal combustion engine to achieve the supercritical temperature.

A corrosive gas resistant laminate comprises an outer polymer layer desirably containing a volatile corrosion inhibitor therein, a corrosion gas resistant barrier layer that can be a hydrophilic polymer, and a tie layer located between said outer and said barrier layers. The various laminates have improved transmission resistance with regard to corrosive gases such as oxygen, hydrogen sulfide, and halogen gases such as chlorine. The laminates can be used to protect metal during storage and transit.

Corrosion management systems protecting against or managing corrosion of various components in generally vertically oriented structures, that can be located one or more of aboveground and underground. The corrosion management system includes a dispenser system that dispenses at least one corrosion inhibitor to the structure desired to be protected at a plurality of different vertical heights.

A system for protecting storage tank soil side bottoms against corrosion includes a pipe system comprising non-perforated inlet pipes and perforated pipes connected thereto. A sleeve container having solid VCI compounds therein is inserted into the perforated pipes. The sleeves are permeable to vapors emitted by the solid VCI compounds and flow through the pipe to a perforation where they are admitted into an area beneath a storage tank so that they can contact the tank bottom (soil side) and protect the same from corrosion. Alternatively, solid SCI compounds can be used in combination with VCI compounds. The corrosion protection system is designed to be used with aboveground storage tanks. This includes, but is not limited to, single bottom tanks: newly installed or existing tanks undergoing bottom replacement or installation of double bottoms. These tanks are located on substrates such as the compacted soil/sand or hard substrates such as concrete, bitumen mixtures and asphalt where channels can be cut into the substrate for installation of the pipe system.

The present invention generally relates to corrosion management systems designed to deliver corrosion protection and/or the management of corrosion to a top portion of an enclosure (e.g., storage tanks, cisterns, containers, etc.). In one embodiment, the present invention relates to corrosion management systems designed to deliver corrosion protection and/or the management of corrosion to a top portion, or roof portion, of an enclosure where such a system includes one or more dispensers designed to deliver at least one corrosion inhibitor to a system designed to protect a top portion of an enclosure (e.g., storage tanks, cisterns, containers, etc.).

A smart enclosure protection system for packages containing one or more metals comprises various sensors such as relative humidity, temperature of the metal, temperature within the package, a volatile corrosion inhibitor sensor, as well as a relative humidity sensor. Upon a computer receiving a signal from one or more of the noted sensors that the sensing item is either above or below a predetermined value, it will send a signal to one or more dispensers such as a dehumidifying compound dispenser, a volatile corrosion inhibitor compound dispenser, a soluble corrosion inhibitor compound dispenser, or a chemical fluid absorber or scavenger dispenser to dispense one or more such dispensing compounds that abates or removes an actual or a potential corrosion inhibiting situation.
