Product Description：
Liquid nitrogen wash cold box
In the new synthetic ammonia industry, the cryogenic cleaning process, rectisol process plus cryogenic liquid nitrogen washing, has the features of low energy consumption equipment reliability and environmental friendliness. For 2007,most of the new constructing ammonia projects in Chin use the cryogenic technology for the syngas purification.
Application of liquid nitrogen washing process: the feed gas(hydrogen)of synthetic ammonia contains nitrogen, as well as impurities like Carbon and oxygen compounds(such as carbon monoxide,carbon dioxide,etc) argon and sulfides,which could not satisfy the requirements of subsequent process. Normally rectisol plus liquid nitrogen washing process will be used t remove these impurities. Liquid nitrogen washing process is a cryogenic purification method using cryogenic distillation to obtain high purity hydrogen, then mix hydrogen and nitrogen by 3:1 to be used for ammonia synthesizing.Particularly the output from cryogenic liquid nitrogen wash device has carbon monoxide content less than 2 ppm, which effectively improves the efficiency of the synthetic ammonia catalyst, reduces the synthesis pressure, eliminate the relief gas, so as to achieve the effect of energy saving and long period operation, low emissions.
Ethylene cold box
CYY Energy has the technology and equipment for the design and manufacture of milion ton per year ethylene cold box and column overhead condenser, PV.Zhongtais familia with ethylene process like Lumus, SW and Linde process.
Propane dehydrogenation propylene (PDH) cold box
As important chemical raw material, propylene and butylene are in big demand in the domestic market. They are mainly prepared through catalytic reaction of dehydrogenation of propane and butane. At the moment, there are several processes like Oleflex process from UPO, Catofin process from Lummus-Houdry and STAR process from Krupp Uhdewcng, which have been commercialized.Often propylene and ethylene are used in the propane dehydrogenation (PDH) process to realize gradual cooling and separate olefins. In the low temperature section, we use multi stream Cold box.
Methanol to olefins cold box
MTO (Methanol to Olefins)and MTP(Methanol to Propyene) are two new important process or methane chemical industry.It s a chemical technology,using methanol synthesized from coal or natural gas as raw material, with a fuidized bed reaction which is similar to catalytic cracking unit producing low carbon olefins. The cryogenic separation section of olefin separation uses a multi-stream cold box.
Carbon monoxide cold box
Carbon monoxide is an important chemical raw materials which can be used for the synthesis of a variety of high value added products, such as acetic acid, acetic anhydride, formic acid, dimethyl formamide, light gas and metal carbonyl compounds, etc. When syngas is used to produce methanol, acetic acid, ethylene glycol and other products, cryogenic separation is always applied to separate syngas into rich H2 gas and CO products. Typical H2/CO cryogenic separation and CO cryogenic purification process has two major methods: condensation method and methane wash process.
Natural gas liquid recovery cold box
Based on feed gas pressure, composition and product requirement, different process could be applied like propane refrigeration process, expander refrigeration or mixed refrigerant cycle, thus to realize customer demand for separation, liquefaction and recovery of hydrocarbons like ethane, propane.
