气压机(国外英文资料) I. The purpose of compiling the winter operation method of heavy pressing shop In order to ensure a workshop in heavy oil catalytic safe produce, especially in the northern winter easy to freeze production environment, ensure the safety of production in winter, not frozen, frozen one inch pipeline and equipment. In accordance with the relevant requirements of winter safety production companies and refineries, the production characteristics of combined device, antifreeze, implement the joint anti coagulation device and heat insulation work, need to clarify the status of winter antifreeze anti coagulation function, so that workers in the winter production well documented, rule-based, winter operation law is formulated a heavy oil catalytic the workshop monitor reaction, fractionation, absorption, stable product refining, gas separation, main air unit, air compressor position, the operating personnel strictly. Two, winter operating method of the use of the scope and execution time 1, the execution time is from October 10, 2012 to April 15, 2013. 2, the scope of application: device, refined product of 1.0Mt/a heavy oil catalytic cracking unit and supporting the two sets of gas fractionation unit, winter equipment running start and shutdown scheme, safety equipment, pipeline and scheme of winter winter emergency treatment \ Adjustment of cooling water According to the characteristics of winter temperature is relatively low in Daqing area, energy saving and anti freezing principle, the same line of both air cooling and water cooling, to air cooling is the main means of regulation, and to do water aid, but cooler and water side, to maintain proper opening, to prevent the generation of the cecum dead. After the adjustment of the cooler, it is necessary to meet the requirements of the circulating water flow rate in the regulations of the Daqing Petrochemical Co on industrial water management 1.2.1 cooling water temperature indicator may be relaxed in the winter,
