Reliability And Availability

Reliability and availability are important symbols which weigh the reliability of product. Chemical production equipment system is consisted of many single devices. Due to special dangerous, the reliability analysis to whole equipment system is very important to keeping the safety of production process. In this article, to chemical process equipment system, the reliability calculation method, basic principles, basic assumptions and calculation program are described. To a aromatic semi-renewable dehydration process system, by using the reliability calculated method above, the fault tree and reliability block diagram are derived, the system reliability and availability are accounted, the corresponding reliability and availability curves are obtained and the main factors influencing the reliability of the system are analyzed.

The causes that lead to the shrunken cause of dome roof oil tank were analyzed and some practical measures were offered for the prevention of this kind of shrunken, which is valuable about ensuring security of oil tank and protection of external pressure caused destruction in oil tank. With the rapid development of China's oil economy, increased dramatically the demand for large-scale storage and transportation equipment. In the refining and chemical production equipment, the vertical cylindrical steel dome tank is a widely used storage device, it is low cost, easy to operate. Mainly used for storing crude oil, diesel and some chemical products. Tank design pressure is lower, the tank wall, tank top, tank bottom are thinner, and it is easy depression because of large negative pressure inside the tank in the course. Therefore, the correct understanding of the reasons of depression and mastering tank preventive measures, security maintenance for the storage of equipment is very important. In this paper, a refinery in Harbin City, take the dome tank as an example of crude oil and analysis cause of their depression.

Somatic Diseases

Due to the modernization of chemical production in recent years, specialists note a reduction in detection of occupational intoxication and a decrease in the overall occupational morbidity of workers in the chemical industry. At the same time, the risk of loss of professional aptitude for general medical contraindications and the preservation of the functional longevity of employees comes to the first place. The study aims to conduct a comprehensive analysis of the current state of working conditions and health from chemical organ synthesis enterprise employees. The experts analyzed the state of working conditions of production workers under a special assessment of working conditions. In addition, we studied the status of the leading professional groups of the enterprise according to the results of a periodic medical examination (PME). The working conditions in the primary professions of the enterprise for the production of acrylic acid nitrile, sodium cyanide, and related products are harmful to 1-3 degrees (subclasses 3.1-3.3). Scientists estimated the a priori occupational risk to employees' health from exposure to harmful factors of the production environment in the categories from small (moderate) to high (intolerable), where it is necessary to take urgent measures to reduce it. Scientists recognized three employers out of 522 who work in harmful working conditions for general medical contraindications (coronary heart disease) as unfit for professional work. We allowed 14 people to work in the profession with restrictions. Specialists identified common somatic diseases in 335 people: sciatica of the lumbosacral level (23.7%), chronic bronchitis (15.3%), essential hypertension (14.4%), and cerebral atherosclerosis (12.3%). The employees of chemical organ synthesis enterprises work in harmful working conditions, namely: the presence of toxic chemicals in the air of the functional area, an increased noise level generated by working production equipment, and the severity of the labor process. An adequate system of hygienic monitoring and organizational and technical measures makes it possible to reduce the class of the degree of harmfulness of working conditions according to the chemical factor to acceptable ones. Polyethological general somatic diseases create the most significant risk of loss of professional aptitude in personnel. Harmful factors of work and lifestyle aggravate the involutional processes.
