Progress on the construction of the methanol production project using coke oven gas in a comprehensive manner by Ningxia Baofeng Energy Group Co., Ltd. Author/Source: Coal Chemical Engineering 114 Forum Date: 2021-09-06 Clicks: 8 Recently, the converter, waste heat boiler, and steam superheater of the conversion unit in this methanol production project are about to be completed and delivered. Among them, the waste heat boiler was designed and manufactured by Lansi Heavy Equipment; it features a vertical structure with a combination of flexible thin tube sheets and thick tube sheets, and its heat exchange tubes are spiral coiled tubes, making its design and manufacture quite challenging. Focusing on the challenges associated with the manufacturing of equipment internals, the production workshop worked together with technical staff to innovate boldly, optimize the manufacturing processes, and develop implementation plans. This complete set of equipment utilizes a new technology to address the issue inherent in the traditional pure oxygen non-catalytic conversion process (referred to as POX process), namely the inability to produce superheated steam that can be used as power steam, aside from saturated steam. It is the first set of equipment in China designed to generate superheated steam using this process. Lanshi Heavy Equipment has completed the development of the core equipment for this unit, namely the conversion furnace, waste heat boiler, and steam superheater, which will further enhance the company’s market competitiveness in terms of core equipment for POX waste boiler process units. To make comprehensive use of the coke oven gas generated as a by-product of Ningxia Baofeng Energy Group Co., Ltd.’s 3 million tons per year coal coking integrated production project, it has been decided to invest 654.34 million yuan in building the “Ningxia Baofeng Energy Group Co., Ltd. Coke Oven Gas Comprehensive Utilization for Methanol Production Project”. Upon completion of the project, the annual methanol production capacity will be approximately 400,000 tons per year. The project is located in Areas A and B of the Linhe Comprehensive Industrial Park within the Ningdong Energy and Chemical Industry Base, occupying 3,300 m2 of industrial land. The main facilities to be constructed include coke oven gas pretreatment units, coke oven gas compression units, TSA units, low-temperature methanol washing units, methanol synthesis units, flare units, as well as various supporting auxiliary facilities ； Units for wastewater treatment, circulating water, air separation, etc., rely on existing facilities. In April 2020, Baofeng Energy’s 3 million tons per year coal coking integrated production project was officially launched as one of the first major projects in the Ningdong base for that year. This project features a high degree of integration, a complete downstream industrial chain, a wide range of applications for raw coal with high utilization efficiency, significant scale advantages, and enhanced profitability. Once the project is completed and put into operation, the company’s coke production capacity will reach 7 million tons per year, making it one of the largest independent coking enterprises in China and contributing to the development of the coke industry in a direction that emphasizes clean and efficient production methods. At the same time, the integrated circular economy industrial chain of \"coal, coke, gas, chemicals, oil, and electricity\" has been strengthened, enabling the transformation of coal resources from a fuel source into chemical raw materials as well as their clean and efficient utilization.
