A tercopolymer of epichlorohydrin-ethylen oxide-allyl glycidyl ether (ECH-EO-AGE),having the inherent viscosity of 4.0-4.5,was prepared withAl(i-Bu)3-H3PO4-H2O -N(CH3)2 catalys system. The correlations between the compositions of the tercopolymers and their crystallization and water absorbency as well as their physical properties were investigated. X-ray diffraction indicated that the ECH-EO-AGE tercopolymer appeared to be an amorphous structure, and the water absorbency increased with increasing the content...

A tercopolymer of epichlorohydrin-ethylen oxide-allyl glycidyl ether (ECH-EO-AGE),having the inherent viscosity of 4.0-4.5,was prepared withAl(i-Bu)3-H3PO4-H2O -N(CH3)2 catalys system. The correlations between the compositions of the tercopolymers and their crystallization and water absorbency as well as their physical properties were investigated. X-ray diffraction indicated that the ECH-EO-AGE tercopolymer appeared to be an amorphous structure, and the water absorbency increased with increasing the content of EO, but with decreasing the absorbent temperature. When the content of EO was up to 40%, the maximum water absorbency reached 250%.It showed that the process was physical absorption.The rolling behaviour of ECH-EO-AGE tercopolymers and the physical properties of their vulcanizates ( tensile strength 280 kg/cm2, elongation 360% ) were superior to those of ECH-AGE copolymers.

使用三异丁基铝-磷酸-水-二甲基苯胺四元催化剂合成了比浓对数粘度为4.0—4.5的环氧氯内烷-环氧乙烷-烯丙基缩水甘油醚(ECH-EO-AGE)三元共聚物。用 X射线衍射等手段研究了结沟组成与结晶性能及吸水性能之间的关系,并对其物理机械性能进行了研究。结果表明,ECH-EO-AGE三元共聚物无结晶存在,属于无规共聚物。吸水率随 EO含量的增加而增大,EO含量为 40%时,最大吸水率达250%;温度增加,吸水率反而下降;吸水过程属于物理吸附。硫化胶的物理机械性能(抗张强度为280公斤/厘米~2,伸长率为360%)和辊筒行为均优于ECH-AGE二元共聚物,可作为一种新型的特种橡胶。

Cold-flow model experiment was carried out in rotating packed bed(RPB)to remove acid gas from pyrogas.Mixed gas of air and carbon dioxide was used as simulated pyrogas and sodium hydroxide solution as absorbent.The gas phase mass transfer coefficient(K_Ga) was function of liquid flow rate,concentration of absorbent,gas flow rate,content of carbon dioxide,rotating speed and absorbent temperature.Change of K_Ga was within the range of 0.2 and 3.0s~(-1).It increased with increasing liquid flow rate,gas flow rate and adsorbent temperature but decreased with increase of carbon dioxide content.It was not considerably affected by rotating speed of packed bed.Cold-flow model experiment showed that content of acid gas in pyrogas could be reduced from 1.00% to 1×10~(-6) in RPB under industry conditions.The RPB process was more effective in absorption of carbon dioxide than traditional process.It could be applied in gas-liquid separation.

用空气和CO2的混合气体模拟裂解气,在旋转填充床中进行酸性气体吸收实验。考察了吸收液流量、吸收液浓度、空气流量、空气中CO2含量、旋转填充床转速和吸收液温度对气相传质系数(KGa)的影响。实验结果表明,KGa为0.2~3.0s-1时,KGa随吸收液流量、吸收液浓度、空气流量、旋转填充床转速和吸收液温度的升高而增大,随空气中CO2含量的增加而减小。用冷模数据推算工业操作条件(约1.5M Pa,50℃)下旋转填充床的吸收效果,预计可将裂解气中酸性气体的体积分数由1.00%降至1×10-6以下。旋转填充床脱除裂解气中酸性气体的效果优于传统的脱除工艺。

For the sake of removing hydrogen sulfide from flare gas,AMSIM module with Kent-Eisenberg thermodynamic model was used in simulation of absorption process with N-methyldiethanolamine(MDEA)as absorbent.The calculation was first checked by simulation of desulfurization of dry gas and liquefied gas from refinery.The model was proved to be appropriate for simulation of MDEA desulfurization.The effects of inlet pressure of flare gas,contents of hydrocarbons and operation parameters of absorber on desulfurization were then investigated.The main obtained parameters of absorber are as follows:flare gas temperature 30 ℃,pressure 0.45 MPa,flow rate 16 000 m~3/h;absorbent temperature 35 ℃,MDEA mass fraction 25%,flow rate 10.0 m~3/h;and absorber tray number 15.Under above conditions,mole fraction of H_2S in flare gas to be treated can be reduced to less than 1.00×10~ -4 with high desulfurization selectivity.

针对火炬气的工况,选择N-甲基二乙醇胺(MDEA)吸收法进行火炬气脱硫,以满足进一步利用火炬气的要求。采用AMSIM模块进行脱硫模拟计算,其中热力学方法选择Kent-Eisenberg模型。用炼油厂干气、液化气脱硫的实际操作数据对模拟方案进行检验,证明此热力学模型适用于MDEA吸收法脱硫过程的模拟。根据火炬气实际操作情况,分析了火炬气进口压力、碳氢化合物、吸收塔操作参数对脱硫性能的影响。模拟结果表明,当火炬气流量16000m3/h(标准状况下)、温度30℃、压力0.45MPa;循环MDEA溶液中MDEA质量分数25%、流量10.0m3/h、温度35℃;吸收塔的塔板数为15时,可将火炬气中H2S脱除到摩尔分数1.00×10-4以下,且具有较好的脱硫选择性。
