The application of corrugated packing in fine chemical industry of wire mesh and stainless steel orifice plate
My company production of stainless steel wire mesh corrugated packing and metal orifice plate corrugated packing is mainly used in petroleum chemical industry, fertilizer industry, natural gas purification, smelting, etc., such as coal chemical industry ethyl benzene ethylene separation, preparation of high purity oxygen, epoxy propane separation, butane tower, cyclohexane recovery, gas fractionation, atmospheric and vacuum refining device, etc.
1, metal, stainless steel wire mesh corrugated packing and metal orifice plate corrugated packing in the application of formaldehyde absorption tower reconstruction: first formaldehyde absorption tower 1 m in diameter, height of 8.46 m, 24 layer sieve plate, formaldehyde production 15000 tons/year, with the increase of yield, resistance increases, the absorption system first liquid absorber is generic, more than expected, and consumption increase caused by formaldehyde.We use metal mesh corrugated packing and modification of orifice plate corrugated packing, spray device selection trough type liquid distributor and multi-tube disc redistributor, effect is good after putting into production, greatly reduces the second tower load, effectively reduced the second liquid absorber formaldehyde concentration, reduce the aldehyde content in tail gas, reduces the methanol unit consumption, and reduced the pollution of the environment, because the new packing small resistance, large flux, increased the yield of formaldehyde, the economic benefit is remarkable.
2, metal wire mesh ripple packing used in separation of isomers of nitrotoluene effect: wire mesh corrugated packing vacuum distillation method is used to replace the plate tower distillation and crystallization group legal successful, 4 times higher separation efficiency, extracting high purity products, adjacent nitro toluene was 99.96%, and the purity of nitrotoluene purity of 99.8%, between nitrotoluene purity of 99%, has entered the international market, compared with the plate tower, tower of the same diameter 2 times higher production capacity, promote seven miss 40 million sets of production equipment investment, and output value of 250 million, taxes andprofits each year more than 40 million yuan.
3, metal wire mesh ripple packing in the successful application of isopropyl phenol isomers separation: use a metal wire mesh corrugated packing tower distillation separation success isopropyl phenol isomers, product adjacent isopropyl phenol content reached 99.9%, the tower kettle isopropyl phenol residual amount is only 0.02%, recovery rate is high, the product quality to achieve export index.
