Total investment and daily operating costs of the combined purification system using low-temperature methanol washing and liquid nitrogen washing
Thread Content
There is an urgent need for investment and operational costs for a raw material gas purification unit for an ammonia synthesis plant with an annual production capacity of 300,000 tons. Precision isn’t necessary; an approximate figure will suffice. A combined low-temperature methanol washing and liquid nitrogen washing system is preferred, though NHD and MDEA options can also be considered. Please, someone experienced can help this newcomer out. Thank you! ! !
The main investment is focused on several low-temperature cooling towers and shell-and-tube heat exchangers; for liquid nitrogen washing, the entire cooling box system is purchased, with costs in China being around 30 million yuan.
