Progress of the Phase 4 Ping’an Project at China Coal Pingshu Author/Source: Saiding Engineering Date: 2022-01-28 Clicks: 2 Currently, the Phase 4 Ping’an project at China Coal Pingshu is in the commissioning phase, with auxiliary production facilities such as the integrated water supply system, air compression nitrogen generation station, 35KV substation, **switching station, and heat exchange station already in operation； In the main production unit, **the conditions for trial operation with feedstock supplied via the main pipeline are met; nitric acid is currently undergoing oil washing in the four-in-one unit, and issues related to the three inspections and four adjustments in various units are being addressed. Project Overview: In 2021, the Phase 4 technical renovation project at China Coal Pingshu Pingan resumed construction, using liquid ammonia supplied by a low-quality coal project as raw material to produce porous **. The production facilities include a 150,000-ton/year nitric acid plant, an 180,000-ton/year *ao acid an plant, along with supporting utility systems. At present, the installation work is nearly complete; the circulating water system has been put into operation, the medium-pressure steam system is undergoing purging, and the nitric acid combined unit is under maintenance. The hydraulic testing of the plant’s systems has been completed, as well as the individual tests of the motors. Water circulation testing will begin after heating is established. It is expected that the plant and the nitric acid production unit will start up for trial operation on November 30, 2021, and December 15, 2021, respectively.
