Polpan / Merpan Process Stabilizing
Unit 80 is a plant with set chemistry and well defined actions to be taken. After studying the process we were able to offer automation of these while maintaining the ability of the operators to override all decisions.
Main topics of the project:
- Automate the process of starting the process.
- Enabling the operator to keep the process exactly where it should be.
- Operator can overrule the system.
- Can accommodate higher levels of control with no changes.
pH control is considered by the majority of Process Control Experts as the most difficult one topic control job.
Careful study the unique situation in each project together with cautious implementation of advance process control techniques brings excellent results to the full satisfaction of the projects’ goals.
pH control is found in Processes, in effluent treatment plants in scrubbers and more.

Wet Scrubber Process Control
Wet Scrubbing plays important role in Gas Cleaning operations.
As such it is widely used where gases that are released to the atmosphere have to meet the environment standards.
In the DSW case we had to take care of the brine collected at the system bottom to meet the required pH values as well to be suitable to be released to the sewage.
In refining projects, sour gases were treated to reduce the sulfur content down to acceptable levels.
