Oil Refinery and Petrochemical Industry Wastewater Treatment

Introduction

Petroleum refining and petrochemical industries unavoidably generate large volumes of wastewater. As environmental regulations for wastewater disposal become stricter and freshwater resources become increasingly limited, the industry requires more efficient management and reuse of this wastewater. Therefore, every oil refinery and petrochemical company must explore and resolve wastewater treatment.

This oil refinery and petrochemical wastewater treatment course will identify how to get to the core of this issue using a thorough analysis of the development status of wastewater treatment methods, including flotation, coagulation, biological treatment, membrane separation technology, combined technology and advanced oxidation process that ultimately results in maximization of petroleum refining and petrochemical industries profitability and meeting with the strict environmental regulations.

In this oil refinery and petrochemical wastewater treatment training, participants will learn several configurations and techniques for Wastewater Treatment Plants (WWTP) in oil refining and petrochemical industries.

Course Objectives:

At the end of this oil refinery and petrochemical wastewater treatment course, the participants will be able to:

• Learn the purpose, principles of operation, and limitations of the different wastewater treatment technologies in oil refining and petrochemical industries.
• Understand how to establish high wastewater recovery for reuse onsite, reduce freshwater intake, and meet strict regulatory requirements.
• Understand the advanced, cost-effective technologies for reducing waste volume and obtaining Zero Liquid Discharge (ZLD).
• Learn how to reduce wastewater treatment facilities' energy consumption and operational costs and optimize treatment conditions.
• Learn industry-standard targets for wastewater before discharge or reuse.
