Overall design and assorting engineering

Storing and shipping engineering was rapidly developed. A number of state conserving stock, commercial conserving stock and product oil pipeline projects were built in Zhenhai, Beihai, Beisanling, Rizhao (Shandong) and Yangpu (Hainan). Domestication of large containers and materials was achieved, 15×104m3 storage tank, spherical tank, high-strength steel plate and long distance pipeline used steel for example. Qingdao and Beihai LNG receiving station projects were completed and proved well in practice, and were promoted and applied in Tianjin.

Environmental protection emissions cutting technique, represented by flue and gas desulfurization and denitration technique, was widely promoted and applied. Over 50 flue and gas desulfurization and denitration technique units were completed; such environmental protection techniques as chemical exhaust (HPPO exhaust) catalytic oxidation burning treatment, refinery plant hydrogen sulfide wet process sulfuric acid preparation, oil and gas recovery treatment, refinery plant exhaust comprehensive treatment, refinery waste water treatment and recovery and oily sludge treatment have been successfully developed and applied. Reproducible wet process flue and gas desulfurization technique and biological fluidized bed sewage treatment technique gained important stage fruits.

In the area of equipment upsizing and major unit domestication, development and successful application of major ethane “three machines”, massive compressor, ethene cold box, massive hydrogenation reactor, massive styrene reactor, ethylene oxide multitube reactor, wound-tube heat exchanger, powder and granule feeding and DCS system have greatly supported the technical process of equipment localization and pulled development of domestically manufactured materials.
