Shenhua Ningmei 4-million-ton-class coal indirect liquefaction project

Our company has undertaken the fabrication of equipment for the Shenhua Ningxia Coal-to-Oil Chemical Co., Ltd.’s 4-million-ton-per-year indirect coal liquefaction project, including more than 130 units such as oversized reactors, tower vessels, heat exchangers, and storage tanks. Among these are four Fischer–Tropsch synthesis reactors, each with a diameter of 9,600 mm, a height of 61,385 mm, and a wall thickness of 130 mm, fabricated from SA387 Gr11 CL2 steel. Each unit weighs approximately 2,200 tons. On-site fabrication involved segmental manufacturing and transportation, or on-site rolling; the reactors were assembled horizontally into two sections, followed by heat treatment. Subsequently, the two sections were erected vertically for alignment, welding, localized heat treatment, and hydrostatic testing.
