The Egyptian Ethylene and Derivatives Company (ETHYDCO) is a joint venture company established with the purpose to produce Ethylene, Butadiene and their derivatives (Polyethylene, Poly Butadiene).
As part of ETHYDCO’s petrochemical complex in Alexandria, a 460,000 T/Y ethylene plant and a 20,000 T/Y butadiene extraction plant were built.
For its water needs, ETHYDCO took the initiative to contract a zero liquid discharge plant that is the first of its kind in Egypt. The feed water to the plant is a mix of treated effluent and Nile River water. Due to the high variability of the inlet feed water, technologies designed to operate over a wide range of feed conditions were evaluated.
QUA’s FEDI was chosen due to its capability to handle variable feed conditions with its two-stage design.
