Printed Circuit Plate Heat Exchanger (PCHE)

Shen's plate Heat Exchanger is divided into PCHE, PFHE and H2X three kinds, of which the Printed Circuit Heat Exchanger (PCHE) is a heat exchanger plate superposition with chemical etching or fine processing of millimeter (channel diameter of 0.1~2mm). Compared with traditional heat exchangers, the heat exchanger of this structure has the advantages of high pressure resistance, high and low temperature resistance, corrosion resistance and high heat exchange efficiency.PCHE heat exchanger was first invented by a British company, Shen introduced the technology in 2011, and has been committed to replacing foreign products in the field of offshore ships, LNG, hydrogen energy and other fields to reduce manufacturing costs.

Case Story

PCHE Heat Exchanger in LNG Field

In October 2020, the microchannel compact high-efficiency heat exchanger (PCHE) engineering prototype, jointly developed by CNOOC Gas & Power Group Co., Ltd., CNOOC (China) Co., Ltd. Shanghai Branch, and Hangzhou Shenshi Energy Conservation Technology Co., Ltd., passed the achievement appraisal of the China Machinery Industry Federation. This development filled a domestic gap, reached the international advanced level overall, and can be applied in the marine oil and gas/LNG and related fields.

Natural Gas Cooler

At the end of 2021, the first set of domestically produced large-scale high-efficiency compact wet natural gas coolers (PCHE), jointly developed by Hangzhou Shenshi Energy Conservation Technology Co., Ltd. and CNOOC Gas & Power Group Co., Ltd., was officially delivered after passing CCS certification. It was installed on a CEPA platform in a gas field of CNOOC (China) East China Sea Xihu Oil & Gas Operation Company. This marked the mass production of large-scale printed circuit heat exchangers by Hangzhou Shenshi in the marine engineering field.

Compressor Aftercooler

In December 2023, Shenshi Technology successfully developed and delivered three ultra-large dry gas compressor aftercoolers (PCHE) with a power of up to 12MW, further increasing the production capacity of an offshore oil and gas platform in the East China Sea. In the natural gas processing system of offshore oil and gas platforms, dry gas compressor aftercoolers play an indispensable role. The natural gas extracted from offshore oil and gas platforms needs to be quickly, efficiently, safely, and stably transported through subsea pipelines to onshore storage facilities, generally using pressurization to increase gas density and reduce storage volume.
