Study On Process Reformation Of Phenol Acetone Plant

Phenol(PH) is one of important organic chemical raw materials, mainly used for the preparation of phenolic resin, caprolactam, bisphenol A, alkyl phenol, salicylic acid, etc., can also be used as a solvent, reagent and disinfectant. It is applied in the field of synthetic fiber, synthetic rubber, plastics, pharmaceuticals, pesticides, flavors, dyeing and coating etc..In recent years, with international and domestic products of phenol phenol plant have been put into production, the increasingly fierce market competition, enterprises are faced with declining efficiency, backward production technology, the problem of high energy consumption of materials. In order to solve the above problems, we carry out phenol acetone device for tapping the potential synergies technology research, is committed to solve the phenol production technology bottlenecks and quality problems. The development and application of energy saving technology, proposed and optimized technical improvement scheme, provide a reliable technical basis for the technical transformation of equipment. Through the implementation of technological transformation, phenol acetone plant oxidation, decomposition reaction of acetone and phenol refining unit optimal control and energy saving technology application, the phenol acetone plant production and consumption reduction targets, reduce the production cost, effective improvement in phenol acetone plant technical and economic level, good economic benefit and social benefit.Through to phenol plant related products and intermediate products analysis methods to conduct a comprehensive carding, reference to similar unit analysis method to determine the new analysis method, to solve the problem of previous analysis data is not accurate, the reproducibility of. To provide a reliable guarantee for the optimal operation of phenol plant.In this paper, the phenol acetone plant alkylation, oxidation, concentration, decomposition and distillation units load capacity test, find out the bottleneck to restrict the improvement of the production capacity of the unit. To solve the cumene oxidation unit fresh alkali washing capacity is low, the decomposition unit load, refining unit of product quality problems.In the process of refining unit simulation research and laboratory research based on, re design the process, put forward the option of reforming, under the premise of keeping the main equipment are not replaced, the light tower off and finished products were the creation of sidestream, successfully solve the alpha methyl styrene products quality problems.
