What is the development situation of PCHE in domestic offshore oil and gas field?

        The printed circuit board heat exchanger (PCHE) itself is a clean and environmentally friendly product with considerable energy-saving effects, and the economic benefits it can bring are even more impressive. It is estimated that by 2022, the demand for PCHEs is about 500 units, worth about 2.5 billion to 5 billion yuan. In the field of offshore engineering, PCHEs can greatly save the construction cost of offshore equipment, and can be applied to offshore platforms, floating storage and regasification units (FSRU), FLNG and other offshore equipment.

        Compact and high-efficiency heat exchangers (PCHE for short) are widely used in floating liquefied natural gas production storage and unloading units (FLNG), floating storage regasification units (FSRU) and offshore oil and gas production platforms. They are used in the development of oil and gas resources in the South China Sea and the entire ocean Core equipment.At present, the equipment is monopolized by Heatric in the United Kingdom, resulting in extremely expensive equipment, with a single quotation as high as millions of dollars. Heatric has supplied a total of 2500 PCHEs worldwide. Due to the lack of my country's high-end deep-sea key technology and equipment development capabilities, it does not have the ability to localize PCHEs for offshore oil and gas fields, which has become an important factor restricting my country's deep-sea oil and gas resource development. The PCHE high-efficiency heat exchanger used in the offshore oil and gas field is a core key technology that has been "stucked" by foreign countries, posing a threat to my country's independent development of deep-sea oil and gas resources.

         Hangzhou Shenshi Energy Conservation Technology Co., Ltd., according to the PCHE thermal design plan provided by CNOOC, produces compact and efficient micro-channel heat exchangers (PCHE) for the offshore oil and gas field, laying the technology for accelerating the localization of my country's independent core equipment basis.

        The compact and high-efficiency micro-channel heat exchanger (PCHE) is used in the offshore oil and gas field. This product fills the domestic gap and has generally reached the international advanced level. It can be used in offshore oil and gas/LNG and related fields. This signifies that China can independently develop and produce efficient and reliable PCHE equipment for offshore oil and gas fields! The localization of the equipment is of great strategic significance and economic benefits for breaking the monopoly of foreign technology, improving the level of domestic equipment manufacturing, and ensuring national energy security.
