The height of the two methanol washing columns were 97 m,which were the largest single project of coal to SNG purification plant in China and the highest cryogenic purification tower in Asia up to now. Affected by length, diameter,quality and other factors, the towers were manufactured by segmented manufacturing and field assembly-welding The existed difficulties and solving methods were introduced in the manufacture process of the large methanol washing column,such as the assemblying of the subsection shell, the controlling of preheat and postheat treatment, the deformation control of heat treatment. The results showed that the measure of the quality control to the equipment was effective and has reference value to the field assembly-welding of similar equipment.

A thermal performance test is conducted on a prototype of half storage type heat exchangers which use stainless steel bellows as heat transfer element, and compared the tested results with the calculated results by HTRI software, then discussed the heat transfer calculation method of this kind of equipment. Under the operating condition of large flow, the overlapped tube bundles for half storage type heat exchanger are designed, which can reduce the heat exchange area and optimize the heat exchange performance of the equipment. And the final operating effect shows that, with this design, the heat transfer coefficient can reach to 1 600 W/(m2 • K).
