Hi Gaurav
I sent an Email with abstract here is the short abstract:

Amine base Vapor Phase Corrosion inhibitor Alternatives to Hydrazine for Steam generating system and Power Plants
Behzad Bavarian FNACE, Lisa Reiner, James Holden and Boris Miksic, FNACE
Abstract
The presence of dissolved oxygen in boiler feedwater and steam generating systems can present serious problems in a steam generating plant by promoting corrosion and thick scale formation in the feedwater system, the boiler and the steam condensate system. Therefore, it is important to remove oxygen from the feedwater and also from the condensate where in-leakage can occur. The first step in the elimination of oxygen from the boiler feedwater is mechanical deaeration. The second step involves chemical oxygen scavenging to remove the residual oxygen. For many years, sodium sulfite and hydrazine were the chemical oxygen scavengers of choice. However, sodium sulfite contributes solids to the boiler water and hydrazine was found to be extremely toxic.
Hydrazine is generally used as an oxygen scavenger and corrosion inhibitor for corrosion control in steam generating systems. Although hydrazine is very effective in this application, it is a genotoxic carcinogen. The use of alternative chemicals such as nontoxic corrosion inhibitors, oxygen scavengers or new oxygen scavenger-free water treatment technologies is highly recommended. A new amine based vapor phase corrosion inhibitor has been developed and was investigated as an alternative to hydrazine. Long term corrosion tests in the hot steam generating closed loop system showed that the corrosion rate decreased from 8.2-8.9 mpy for the control sample to 0.72-0.74 mpy when the loop was washed with a 500 ppm VCI solution. The closed loop system was subsequently maintained at ~ 100 ppm inhibitor for the remainder of testing. When inhibitor was added from the beginning of the test, average corrosion rate was measured to be 1.09-1.24 mpy for a test conducted in the presence of 100 ppm VCI inhibitor. High resolution XPS analysis showed that the amine based vapor phase corrosion inhibitor promoted and stabilized a very protective Fe3O4, magnetite oxide, on internal surfaces of pipes to lower corrosion rate significantly.
This investigation confirmed that this new vapor phase corrosion inhibitor can be an effective replacement for the toxic hydrazine for steel materials exposed to hot steam/hot environments. The major advantage of this new VCI is its very low toxicity that makes it safe and easy to handle in typical application systems.

Dear Members,
Call for Speakers at AMPP2024 Technical Community of Interest (TCI) on Inhibitors Meeting
The Technical Community of Interest (TCI) on Inhibitors will hold an Information Exchange Meeting at AMPP 2024 conference on 6th March from 9:00 am to 10:00 am in room 231. The format of the meeting will be 2 short presentations (20-25 minutes) followed by discussion and I am currently looking for volunteers to present. Therefore, if you are interested in participating and will be attending AMPP, please let me know at aejenkins@slb.com. Suggested areas of interest are below but this is not an exhaustive list:
1. Sustainable and environmentally acceptable inhibitors
2. Inhibitors for renewable energy and energy transition industries
a. CCUS
b. Geothermal
c. Hydrogen
3. Use of digital technologies to:
a. Develop and test inhibitors in the laboratory
b. Monitor and optimise inhibitors in the field
4. Advances in inhibitor technology for traditional industries
a. Oil and gas (including production, stimulation and drilling
b. Water treatment
c. Vapor phase
d. Atmospheric corrosion inhibitors
