Recently, we have witnessed a one-time successful commissioning on our packaged containerized hydrogen generating plant, which exported to South Korea. In order to meet customer’s urgent demand for gas, under the situation of obvious rebound trend of domestic and overseas pandemic as well as the increasing prevention and control, we overcame the difficulties and flied to overseas user’s site for equipment commissioning and achieved a one-time success. All operating parameters of the equipment reached or exceeded the contract targets. Under the strong support of customer and professional guidance and training of commissioning personnel, the plant was handed over to user smoothly.
