Typical Cases
Showcasing Zhanwang's delivery experience in compressor packaging projects across associated gas recovery, high-pressure injection, chemical tail gas treatment, sour natural gas boosting, hydrogen-rich gas compression and tank vapor recovery.
Associated gas recovery on offshore platforms and onshore oil & gas fields
Recovery and boosting solutions for associated gas produced during oil & gas extraction. Packaging design takes into account site conditions, hazardous-area safety requirements and gas composition characteristics of offshore platforms and onshore oil & gas fields, enabling efficient recovery and utilization of associated gas.
High-pressure injection for oil & gas fields
Engineered for high-pressure natural gas and flue gas injection duty, with focus on operating stability, reliability and field maintainability under high discharge pressure. Applicable to high-pressure gas injection for reservoir drive, gas lift and other oil & gas field development scenarios.
Ethylene oxide recovery
Recovery and boosting of ethylene oxide contained in stripping column tail gas. Operating duty involves toxic, flammable and explosive media, imposing strict requirements on system integration and safety. Suitable for tail gas recovery and reuse engineering in chemical plants.
International sour natural gas boosting
Used for boosting and export of H2S-containing natural gas. The packaging design covers selection, qualification and engineering application of corrosion-resistant materials, with project experience in international high-sour natural gas boosting service.
International hydrogen-rich natural gas boosting
Used for boosting, storage and gathering of natural gas with hydrogen content above 75%. Lubricated or non-lubricated cylinders are configured according to the medium characteristics, addressing the specific boosting requirements of hydrogen-rich gases.
Tank vapor and flash gas boosting recovery
Designed for tank vapor boosting and recovery in produced water treatment, storage and transportation facilities. Screw or reciprocating compressors and the tank vapor surge drum are integrated on a single skid, optimizing footprint and consolidating functions.
