Study On Intrinsic Safety Evaluation Model Of Jiahe Polyamide Project

With the development of society,as well as the continuous progress of science and technology,the chemical process has been continuously improved,for the actual production project,has been significantly improved.Because of the backwardness of the traditional process,it is difficult to meet the stringent standards in the production of high pressure and high temperature products.And a lot of safety problems is due to the actual production process and technology is not up to standard,through the early development of safety equipment and equipment,and ultimately improve the quality of production,has important value,this is also an important aspect of production conditions.For chemical plants,safety design is more important than anything else.In the early stage of chemical plant design,intrinsic safety evaluation model is the most ideal evaluation model.The essence of Security said the production process,will not change because of a damage to the equipment or the whole production factors resulting in other conditions the final formation damage,and in the process of the damage,a major impact on the environment,to prevent the emergence of a form of endangering other security.Jia polyamide project is the epitome of chemical plant,is a kind of chemical plant.In order to visualize and concrete,this paper takes the Chia Chia polyamide chip project as an example to study the intrinsic safety evaluation model of chemical plant.The premise of ensuring the inherent safety is to have advanced process support.In the actual production of polyamide is mainly liquid caprolactam as actual industrial raw materials,there is a mixed storage by caprolactam and the corresponding polymerization and cutting and extraction process,and finally drying,conveying and packaging,storage and production of caprolactam concentrate a certain molecular weight of nylon 6 chips,the process approach in foreign countries,which belongs to the advanced technology.Before the construction of the project,it is necessary to establish a certain standard and test conditions.And in the design process also need to establish a certain standard,generally need to record to the relevant departments,the actual production process is the relevant standards and conditions for reasonable integration,making the whole project is safe.In the process of project design and safety,as well as the later production process,it has an important role in the corresponding essential safety,which is of great significance and value for the whole product.Only a good security,in order to ensure the stable operation of the equipment,the smooth process of production,employee safety,family and social harmony.According to the polyamide chips project,according to the process characteristics,firstly introduces the normal chemical equipment essential safety,chemical technology,chemical safety research is necessary and essential safety device now used,the nature of chemical process safety evaluation model,the use of polyamide chip project as an example,through the identification of dangerous source device all kinds of risk,put forward the current situation and problems,according to their risk characteristics,establish the evaluation model of chemical safety device,to solve the problem of chemical plant.According to the polyamide chip project process according to its characteristics,the risk of chemical equipment use of raw materials,to consider the overall process risk,equipment required safety device,the products of four aspects of chemical process,the device itself security analysis of the existing optimization model is improved to the essence of security effect.
