The main processes in a chemical plant (for coal-to-natural gas production) include coal preparation, gasification, shift cooling, purification via low-temperature methanol washing, SNG synthesis, and TEG drying. There are also auxiliary facilities such as thermal power units, air separation plants, electrical systems, water treatment units, instrumentation systems, and a central laboratory. The entire process involves everything from foundation laying and civil construction to equipment installation and piping work, followed by purging and commissioning. I would like to ask those with experience – the veterans in this field – how long the fastest possible time frame for this entire process is
First, it is necessary to determine whether the project you mentioned has been approved Secondly are the environmental impact assessment reports for land, water and electricity, roads, and water resources. . . . They all fall under the preliminary procedures. Once these conditions are met, it depends on your scale, the timing of equipment ordering, the construction plan, and the commissioning process. . . .
Reply to 2# 77544877: It has been approved by the National Development and Reform Commission, and the civil engineering work has already begun; the equipment is arriving one after another. . .
If the time required for the **approval process is excluded, it generally takes three years (in the north) or two years (in the south). It is also affected by the efficiency of corporate operations; generally, private enterprises are much faster than state-owned enterprises.
State-owned enterprises usually take three years, which is considered fairly quick; the key factor is the equipment drawings. Private enterprises generally take one to two years
