Changzheng Engineering Co., Ltd. (hereinafter referred to as “CECO”) , established in June, 2007, belongs to the China Academy of launch vehicle Technology of China Aerospace Science and Technology Corporation, and is specialized in coal gasification technology and key equipment R & D, engineering design, technical services, equipment supply and EPC service.
Based on the advantages accumulated by China Aerospace in the development, production and testing of carrier rockets and liquid rocket engines,CECO has been applied to the field of clean and efficient utilization of coal, thus forming "HT-L Pulverized Coal Pressurized Gasification Technology" with completely independent intellectual property rights in China. It can be widely used in the production of synthetic ammonia from coal, coal to methanol, coal to olefin, coal to ethylene glycol, coal to natural gas and coal to oil, coal to hydrogen and IGCC power generation.
CECO has involved in enacting 4 national standards for gasification industry:
- Specifications of coal for entrained-flow gasifier
- Norm of energy consumption per unit product of methanol—part 1: coal to methanol
- The norm of energy consumption per unit product from coal to synthetic natural gas
- The norm of energy consumption per unit product from coal to olefin
Core technologies
Relying on the advantages accumulated by China Aerospace in the development, production and test of carrier rockets and liquid rocket engines, products of the company is used in the field of clean and efficient utilization of coal, thus forming "HT-L Pulverized Coal Pressurized Gasification Technology" with completely independent intellectual property rights in China.
Through the HT-L Pulverized Coal Pressurized Gasification Technology, coal can be converted with high efficiency, environmental protection and low cost,and it can be widely used in the production of synthetic ammonia from coal, coal to methanol, coal to olefin, coal to ethylene glycol, coal to natural gas, coal to oil, coal to hydrogen and IGCC power generation.
Through the continuous innovation of ten years, the HT-L Pulverized Coal Pressurized Gasification Technology has formed the technical advantages with distinct characteristics:
- Strong operational safety: no equipment and personal injury accidents caused by design;
- Good production stability: the continuous uninterrupted operation(level A) time of the gasifier reaches 385 days (up to August 22, 2017). The longest cumulative operation time of the whole year is 362 days, the cumulative operating time of 16 gasification units is more than 315 days under full load, and the service life of the burner is more than 600 days.
- Wide adaptability of coal: Tianxi project adopts Jincheng anthracite coal("tri-high" coal), gasifier A and B run respectively 313days and 326 days in the whole year; Changshan lignite project enters the stage of safe and stable operation.
- Excellent operation index: the average annual operating and maintenance cost is from 2 to 3 million yuan, leading the industry compared to coal consumption, oxygen consumption, ratio of ash and slag, sewage discharge and comprehensive index industry;
- Good comprehensive utilization: carry out "three wastes" emission quantitative research and process control, gradually realize harmless treatment and resource utilization.
One-stop service
Simulation training: Provide customers with simulation training before driving, and highly simulate the test drive, driving, insurance and accident. Allows the operator to participate in the learning operation all the way before the project starts. After passing the exam, the operator is certified to operate,which effectively reducing the risk of parking due to human error. In the past,the gasifier were commissioned to full-load operation for at least two months. Now it takes only 10 days to drive. The commissioning costs for two months are generally in the tens of millions. If it is a large-scale project, it is several hundred million. After the simulation training, the trainee can save time and produce products early, which solve a lot of investment in commissioning costs, and it bring value to the owners.
Driving service: The experienced professional driving team that participates in all aspects of the entire project from construction to production and long-term maintenance, which ensuring the safe and stable operation of each gasification unit, and setting a safe driving record for all projects. Easy visual operation,one-click start for safe driving. The company promises foreign projects to participate in the field guarantee for one year.
Zero inventory service: The company has spare parts warehouses near the project site, its scope of services covering the whole country project, whichreducing the investment in fixed assets and manpower of customers on spare parts, at close range and responding quickly to customer service requirements. It can guarantee to arrive at the project site in Xinjiang within 24 hours, and other projects can arrive within 12 hours.
Remote Service: Real-time display of the operating status of the gasification plant which helps the customer to perform 24-hour monitoring and early warning, it greatly reducing the risk of shutdown, and providing a strong guarantee for the long-term stable operation of the gasification unit.
Professional maintenance: Adhering to the idea of “Most know aboutequipment for maintenance”, the original technical team personally participatesin maintenance, which conducts repairs and maintenance on the safest way, and outperforms the economic war at the fastest speed.
Project consultation: customized coal chemical construction solutions.
Security check: After the project is put into operation, the safetycommissioner enters the various projects to assist the owner to carry out thesafety hazard inspection and provide constructive suggestions.
