Introduction

Oil Refinery and Petrochemical Industry Wastewater Treatment

Objectives

By the end of this GFTF training course 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 recovery of wastewater for reuse onsite, reducing fresh water intake and meeting strict regulatory requirements
  • Understand the advanced cost-effective technologies for reduction of waste volume and obtain Zero Liquid Discharge (ZLD)
  • Learn how to reduce the energy consumption and operational costs of the wastewater treatment facilities and optimize treatment conditions
  • Learn industry standard targets for wastewater prior to discharge or reuse
  • Identify the impact of pollution on the environment
  • Modify treatment facilities operating conditions according to the properties of incoming polluted wastewater
  • Improve the operability and reliability of equipment
