Ten years of rapid development in chemical engineering technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. Haichuan becomes even better with your involvement – we welcome all to join in the forum discussions. With the hot weather in July, be careful to prevent fires. ---------------------------------------------- Shengli Heavy Industry successfully tested its first set of combustion-driven centrifugal compression units for land-based natural gas terminals. Recently, the first set of such units developed by Shengli Heavy Industry for the second phase of the expansion project at the Ningbo terminal, carried out for CNOOC East China West Lake Oil & Gas Operation Company, passed the initial testing in the turbine company’s final assembly workshop. The unit’s performance was excellent: the vibration level of the compressor at its maximum continuous operating speed was less than 20 microns, which represents an international advanced standard. The Ningbo onshore gas-fired drive compressor project was a key supply assurance project for CNOOC (China) Donghai Xihu Oil and Gas Operation Company in 2022. It represents Shengli Oilfield Equipment Group’s first complete set of onshore gas terminal gas-fired drive units, with the PCL600 compressor model being a compressor design specifically created for integrated domestic gas turbines. Building on existing mature technologies, the structure of the PCL606 compressor, developed for the first time, underwent torsional vibration analysis of the shafting with the gas turbine rotor, ensuring the overall stability of the compressor unit’s rotor. At the same time, the anti-corrosion treatment process for the unit is designed in accordance with offshore platform projects, enabling it to function well not only under land-based terminal conditions but also in offshore conditions. Furthermore, the entire unit has obtained certification from international classification societies, fully meeting the requirements for marine equipment. This unit is also a “smart” unit, equipped with a gas turbine that features one-button start/stop functionality, enabling unattended operation at the site. The station-wide load distribution system for the equipment enables intelligent operation with dynamic adjustment of rotation speed under different loads for new units and those already in use on site.
