Iranian Firm Produces Cold Box Heat Exchangers for Petrochemical, Refinery Industries
The most important applications of the equipment are in NGL, LNG units, ethane recovery in gas refineries, ethylene and ammonia units in petrochemicals, ASU units, and steel and mining industries.
“Our company is active in designing and manufacturing different types of fixed equipment for the oil, gas and petrochemical industries, specially heat exchangers, and the main approach of our company has always been to manufacture high-tech and technically complex exchangers,” said Hadi Soheilipour, the development manager and vice- chairman of the Board of Directors of the company.
“Among the important applications of this advanced equipment are NGL, LNG units, ethane recovery in gas refineries, ethylene and ammonia units in petrochemicals and ASU units, and the production of gases like nitrogen, oxygen, hydrogen, helium, etc. in steel and mining industries,” he added.
“Our company is the first engineering and manufacturing unit in Iran which has managed to design and manufacture cold box heat exchangers,” Soheilipour said.
Cold box is a complete package of brazed aluminum heat exchanger contained in carbon steel casing with structural support, insulation containment, and protection for the internal equipment. Insulation work of heat exchanger and piping assembly can be easily done by perlite insulation and inside of cold box will be pressurized and purged by dry nitrogen gas.
SPP’s cold box can minimize the installation space at the commissioning site by providing the complete unit package of heat exchanger and piping assembly. Also, cold box can be easily installed and easy access to connection piping will reduce the installation work at pre-commissioning.
Also an economic alternative, which saves time during site work, is the installation of different exchangers in a steel containment (Cold Box). Interconnecting piping, vessels, valves and instrumentation are included in this packaged unit to form, after filling with insulation material (perlite), a ready-to-operate unit. Cold Boxes are cryogenic thermal sets that are used in the air separation unit. This thermal set is placed inside the carbon steel metal frame, which is insulated with PERLITE.
