Case Introduction

The ethane and naphtha tank farm renovation project, which our company has signed with Wanhua Chemical Group as a supporting facility for the 1.2-million-ton-per-year ethylene and downstream high-end polyolefin project, is designed to meet the raw-material storage requirements of Yantai Port Wanhua Industrial Park Terminal Co., Ltd. for Wanhua’s Phase II ethylene project, while also ensuring the quality and safety of product storage. The main construction scope of this project includes the erection of two new 160,000 m³ ethane (ethylene) storage tanks along with associated auxiliary facilities, as well as the construction of a new substation, a control cabinet room, a fire‑pump house, and an emergency spill containment pond, among other components.

Our company undertook the construction of the deaerator for this project and delivered the equipment on January 22, 2024. Measuring 21 meters in length, 5.25 meters in width, and 4.7 meters in height, this deaerator is one of our largest fabricated products.

Built-in deaerator

Dutch Stock patent technology—holds a unique and leading position in the deaerator sector.

For units exceeding 200 MW, the overall equipment cost is lower than that of conventional head-type deaerators.

The deaerator room’s height has been reduced by 3 to 4 meters, significantly cutting civil engineering costs.

Reduce costs associated with insulation, platforms, piping, and feedwater recirculation pumps.

Reduce steam consumption; exhaust losses are only 1/6 to 1/5 of those of conventional deaerators, thereby lowering operating costs.

Membrane-type deaerator

Product configuration: deaerator head plus water tank; the deaerator head can be either vertical or horizontal, with the vertical type available in single‑head or double‑head versions.

The feedwater inlet of the spiral‑membrane tube is arranged with uniform cross‑sectional dimensions, resulting in a thin water film, excellent continuity, and high deoxygenation efficiency, with an outlet dissolved oxygen level of ≤7 ppb.

High adaptability: It can achieve deoxygenation under conditions of low‑temperature influent and high‑oxygen‑content influent, provided that a sufficient steam flow is maintained.

The rated load can ensure compliance with effluent dissolved oxygen requirements across a range of 30% to 110%.

Wide range of applicability: 10 t/h to 2,400 t/h, suitable for both fixed- and sliding-pressure operation.
