伴随着我国经济的高速发展,我国的石油化工产品消耗速度越来越快,这对我国的石油化工生产企业提出了更高的要求。为了提高石油化工生产企业的生产效率,石油化工企业在实际生产中,用到了大量的仪表自动化设备,这在很大程度上提高了我国石油化工产品的产量。这些仪表自动化设备属于精密设备,其在使用过程中,容易受到多方面因素的影响,而产生故障。故障的产生不仅会影响石油化工产品的生产进度,更有可能引发生产安全事故。为了降低石油化工企业仪表自动化设备的故障率,对仪表自动化设备的故障预防与维护措施进行探索,希望对提高这些设备的工作稳定性可以起到促进作用。 相似文献

Temporary corrosion protection for plant construction equipment outside of Central Europe. ?Temporary protection against corrosion”? consists of measures for the prevention of damage to equipment by corrosion within a given limited period of time. Essentially, it consists in the protection of machinery, apparatus, fittings, pipelines, measuring and control equipment etc. against atmospheric corrosion in the time between the fabrication of such equipment by the manufacturer and its assembly or commissioning by the firm who is to run the plant. A guaranteed protection against corrosion for a period of two years and more is not unusual. Apart from corrosion, the equipment is also subject to mechanical wear and tear. Worth mentioning here are wear and tear due to, inter alia: buffering during transport by rail; rolling during transport by ship; bending and knocking during loading and unloading; compression during stacking in ships holds and in wharehouses; vibration during transportation. These, in part, quite considerable mechanical stresses which the equipment is subjected to should be taken into account, on the one hand when constructing and installing the equipment, and, on the other, when protecting the equipment against corrosion and when packing. 相似文献

Tokuyama Soda Co. ltd. has developed an energy-saving skid mounted electrodialyzer for sea water desalination. This equipment is suitable for making fresh water for drinking and industrial use. To desalinate 25°C sea water and turn out one ton of product water. This equipment consumes only 8.5 KWH of electricity and 0.09 Kg of concentrated sulfuric acid. Low energy consumption is achieved by adoption of low electric resistance membranes, new spacer and new designed one pass type system. Low running cost, easy maintenance and low initial installment cost place the equipment good position in the desalination field. And also we applied high temperature electrodialysis up to 50°C of sea water and get figure 6.0 KWH for one ton of product water. 相似文献

A 25,000 gpd Absorption Freezing Vapor Compression (AFVC) pilot plant has been built. Additional studies were conducted in order to prepare capital and operating cost estimates on 100,000 and 1,000,000 gpd plants. AFVC is a new freezing process for desalination and other concentration/ separation applications that uses an absorption cycle powered by a heat pump. Power consumption of 42 and 38 kWh/1000 gal. were calculated for the 100,000 and 1,000,000 gpd plants respectively. The 25,000 gpd pilot plant consists of three major process vessels— freezer/absorber, wash column/melter, and generator — and two equipment skids — one for the refrigeration equipment and one for the pumps, air removal equipment and heat exchangers. 相似文献

Safety of equipment destined for the chemical and power generation industries is still mandatory. Structural changes in the equipment manufacturing industry and the current switch‐over to European and international standards harbour potential dangers which can ultimately manifest themselves in plant safety. Items of equipment used in process engineering are generally not mass produced articles with a generally valid safety standard. In contrast, they are subjected to specified loads and in this respect each one to be regarded as one of a kind. Strength testing is a mandatory requirement. This article considers a number of general points demanding attention in design work and future trends affecting design practice. The gap between research and everyday practice has to be bridged by applications‐orientated presentation of results. The paper presents a number of illustrative examples. 相似文献
