The invention relates to a composition for inhibiting corrosion of the upper part (or roof) of a pipeline for conveying wet hydrocarbons, i.e. hydrocarbons comprising a variable amount of water, said composition comprising at least one Amine 1 with vapour pressure greater than or equal to 10 mmHg, and at least one. Amine 2 with vapour pressure greater than or equal to 0.1 mmHg and strictly less than 10 mmHg.

The invention also relates to the use of such a composition, and also to the method of inhibiting top-of-line corrosion employing said inhibitor composition.

A method for controlling water chemistry in a power generation plant including a low-pressure feedwater heater (18), a deaerator (19), and a high-pressure feedwater heater (20) disposed sequentially along a feedwater pipe (16) from a condenser (15) to a steam generator or a boiler (11) to control the chemistry of feedwater guided to the steam generator or the boiler includes the steps of: injecting an oxidant through an oxidant injection line (31) into feedwater flowing through the feedwater pipe disposed downstream of the condenser in such a way that a dissolved oxygen concentration in the feedwater ranges from 3 to 100 ppb while the feedwater is maintained to be neutral to form an oxide film on surfaces of the feedwater pipe, the low-pressure feedwater heater, the deaerator, the high-pressure feedwater heater, and other structural members that come into contact with the feedwater; and injecting a deoxidant through a deoxidant injection line (35) into the feedwater flowing through the feedwater pipe disposed downstream of the deaerator in such a way that the dissolved oxygen concentration in the feedwater flowing into the steam generator or the boiler lowers to 5 ppb or lower.

A method to condense and liquefy vapor by introducing the vapor into a heat exchanger and bringing same into contact with a cooling body in the heat exchanger, wherein a droplet condensation promoting agent is directly added to the vapor introduced into the heat exchanger or to the heat exchanger. A droplet condensation promoting effect due to the droplet condensation promoting agent can be sufficiently manifested and condensation efficiency by droplet condensation can be improved by way of directly adding the droplet condensation promoting agent such as a film forming amine or the like to the vapor introduced into the heat exchanger or to the heat exchanger.

A breathable biodegradable volatile corrosion inhibitor polyester composition comprises one or more biodegradable homopolymer polyesters and/or one or more biodegradable random copolymer polyesters, one or more volatile corrosion inhibitors (VCI), and one or more fillers wherein said composition has a higher water-vapor transmission rate than polyethylene.

A pH-sensitive release system comprising a capsule capable of releasing an agent in both low pH environments and high pH environments. The capsule encapsulates an agent and comprises at least two weak polyelectrolytes (e.g., PEI and PAA). The capsule responds to both low and high pH changes in the local environment by releasing the agent. The agent may include a corrosion inhibitor and may help prevent or ameliorate the effects of corrosion.

The corrosion of unprotected steel substrates causes damage that is costly to repair or replace. Current protective coatings predominately rely on environmentally harmful anticorrosive agents and toxic solvents to protect the underlying substrate. The use of lawsone (2-hydroxy-1,4-napthoquinone) together with a environmentally benign epoxy coating provides an environmentally-friendly alternative for common protective coatings. Microencapsulated lawsone embedded coatings allows the anticorrosive agent to remain dormant until released by damage and is then deposited directly onto the steel substrate. Both visual and electrochemical analysis shows that this self-protective scheme leads to 60% corrosion inhibition in a neutral salt water solution.
