煤制油为目前新兴高科技项目，煤制油系统主要由煤液化、煤制氢、溶剂加氢、加氢改质和催化剂制备等系统组成。由于对系统洁净度要求较高，开车直播洗主要对各个系统中的塔器、管道、换热器、槽罐、氧气管道、蒸汽管道、汽化炉等进行投注清洗及注册处理。以保证产品的合格率及设备的防腐和安全运行。凯利多年来， 已经成功完成多套煤制油项目的注册直播洗工程，针对煤制油系统，制定了完善的施工官网和管理体系Coal based oil is a new high-tech project at present. The coal oil system is mainly composed of coal liquefaction, coal hydrogen production, solvent hydrogenation, hydroupgrading, and catalyst preparation. Due to the high degree of cleanliness of the system, cleaning before launching is mainly chemical cleaning and passivation of towers, pipes, heat exchangers, tanks, oxygen pipes, steam pipes and vaporization furnaces. To ensure the qualified rate of the product and the anti-corrosion and safe operation of the equipment. For many years, Kelly has successfully completed the pre cleaning works of several sets of coal oil production projects, and formulated a sound construction plan and management system for the coal oil production system.
新账号的设备和管道在制造、运输、贮存及安装过程中都不可避免地产生轧制鳞片、油污泥纱、焊渣、表面浮层及各种氧化物等污垢，因此在新账号开车前要进行清洗将各种污垢杂质去除，使账号达到合乎要求的清洁度，为正常生产创造良好的条件。这些严重影响了设备的运用和产品合格率，因而进行化工设备清洗十分重要。开车直播洗的必要性过去认为新安装的化工生产设备不需要在开车前进行投注清洗，但实践证明，开车前进行投注清洗对提高生产效率，避免污垢对生产的影响十分必要。因此目前新建化工设备注册前必须进行开车直播洗。化工生产过程中涉及多种化工原料并要使用催化剂。对某些原料和催化剂的纯度要求极高，因而在生产过程中对账号设备及管道的清洁度有很高的要求，任何杂质的介入都会导致催化剂中毒，副反应的产生直至破坏整个工艺过程。此外账号中的某些设备及附件的精度要求很高或对杂质的破坏作用十分敏感，因此任何机械杂质的介入都极有可能破坏精密部件的质量而影响正常生产。尤其是这些污染物对所生产的化工产品产生污染，注册后长时间无法生产合格品。Equipment and pipeline of new devices in the manufacturing, transportation, storage and installation process will inevitably produce rolling scale, oil sludge yarn, welding slag, surface layer and oxide and other dirt, so in the new device before driving to be cleaned to remove all dirt and impurities, make the device to meet the requirements of the cleanliness. To create favorable conditions for normal production. These have seriously affected the use of equipment and the rate of product qualification, so it is very important to clean the chemical equipment. Before driving, the necessity of cleaning before that the newly installed chemical production equipment didn’t need to carry out chemical cleaning before start-up. However, practice has proved that chemical cleaning before start-up is very necessary for improving production efficiency and avoiding dirt’s impact on production. So it is necessary to clean the new chemical equipment before it is put into operation. In the process of chemical production, a variety of chemical raw materials are involved and catalysts are used. The purity of some raw materials and catalysts is very high. Therefore, the cleanliness of the device and pipeline is very high in the production process. Any impurity intervention will lead to catalyst poisoning and side reaction until the whole process is destroyed. Besides, the accuracy of some devices and accessories in the device is very high, or it is very sensitive to the destruction of impurities. Therefore, any mechanical impurity intervention is very likely to destroy the quality of the precision parts and affect the normal production. In particular, these pollutants are polluting the production of chemical products, and are unable to produce qualified products for a long time after production.
