Note agent (inhibitor) assessment management

 In the case of corrosion status changes frequently, the traditional "one off three note" anti-corrosion methods have been unable to meet the requirements of production, such as electric desalting operation volatile, after desalting of crude oil when the salinity is high low, difficult to control. Demulsifier, neutralization corrosion inhibitor to adapt to the ability of crude oil is low, the existing injection agent technology is difficult to keep up with the properties of crude oil changes, note agent use efficiency is low; Follow-up device corrosion of high temperature and low temperature changes, increase the local corrosion risk. With the corrosion situation of tower system in low temperature, the corrosion effect good note agent application, to solve the corrosion problem of equipment is of great significance.

Job description:

1. make note agent, corrosion inhibitor screening and evaluation plan

2. through the laboratory research of optimization selection of effective corrosion inhibitor

3. industrial application, and indirectly through regular monitoring of water quality analysis data (such as pH, iron ion index values and stationarity), and online corrosion probe position before and after injection agent monitoring data (corrosion rate) evaluation of corrosion inhibitor injection effect. Assessment report issued by corrosion inhibitors

4. according to the corrosion of equipment and combined with the changes of injection agent automatic control system, ensure that the top of the tower of the neutralization corrosion inhibitor real-time and effectiveness of process corrosion protection measures. Better control tower system in low temperature corrosion.
