CO变换操作知识问答

CO变换操作知识问答1. 简述变换反应的原理和目的。

答：所谓变换，是指合成气中CO和蒸汽在一定的温度、压力及催化剂作用下，进行化学反应生成H2 的过程。

化学方程式：CO＋H2O＝CO2＋H2 + Q目的：一是尽可能将CO转化成氢气，二是将水煤气中难以去除的有机硫化物转化为易于脱除的无机硫化物H2S。

2. 变换器入口分液罐的作用。

答：（1）脱除一部分冷凝水。

（2）脱除一部分粉尘粉尘、炭黑等固体杂质，吸附As、Cl－等。

（3）带走一部分铵盐。

3.预变反应器的主要作用答：（1）反应器内装填有保护剂，保护剂主要是废催化剂或者低温催化剂，主要用于阻挡和过滤煤粉尘、炭黑等固体杂质，吸附As、Cl－等对催化剂有毒害作用的组分，以保护耐硫变换催化剂的活性，避免中毒和延长催化剂的寿命。

（2）有一定的变换能力，变换一部分二氧化碳，减低后部反应符合。

（3）为中变提供一部分的反应热量。

4.为什么要设置两段中温变换和一段低温变换。

答：主要是解决速率和速度的问题，在较高的温度下以很快的速度将大部分CO变换成CO2，在较低的温度下尽可能将CO转化成氢气。

如果只用中变，中变的催化剂装填量很大，消耗的水蒸气也多，采用低变，催化剂总装填量下降，消耗水蒸汽量下降，热回收效率高，有效能损失少，热交换设备换热面积可减少1/2左右，可以节省投资，得到较好的经济效益。

5.为什么变换要选择耐硫催化剂。

答：因为汽化炉出来合成气H2S含量有0.15%。

如果变换之前采用氧化锌脱硫，所需要的氧化锌装填量太大，运行成本高，经济效益差。

选择耐硫催化剂有利于流程的设置，克服冷热病，有利于热量的平衡，提高热效率。

6. 变换入口气体为什么要有一定量的硫化氢。

答：变换催化剂在硫化态才具有比较高的活性，硫化反应是可逆的反应。

如果气体中的硫化氢浓度较低，催化剂会出现反硫化，使催化剂被还原，催化剂的活性大幅度下降。

所以要求工艺气硫含量大于0.01%。

7. 耐硫催化剂的种类和特点。

锅炉热效率测定计算的简易快捷方法

锅炉热效率测定计算的简易快捷方法点击次数：6448 发布时间：2009-10-27锅炉热效率测定计算的简易快捷方法㈠采用简易方法测试锅炉热效率的可行性依据现有标准进行锅炉热工测试和计算热效率的结果也存在一定误差，并非完全精确。

我局湘质监特发［2009］99号文件附件3统计，市州特检机构按正规的热工测试方法进行测试需要采购配备大量仪器和设备，需要投入66.84万元。

恕我直言，目前地市级特种设备检验所经济实力不强的情况下，花费近七十万元购买锅炉热效率测试的设备仪表(还不含煤质、飞灰和炉渣可燃物含量的测量设备——测量这两项还要取样送到长沙等检测单位进行)是不现实的。

本人建议，只要配备6.5万元的先进分析仪和设备(还包含相应煤质分析、飞灰和炉渣可燃物含量的测量设备)，采取简易而快捷的方法对燃煤锅炉的热效率进行检测，就可以尽快对燃煤锅炉进行热效率测试；不必花费大量资金、配备大量仪器和设备做为投入，使得燃煤锅炉能效测试工作滞后，影响高耗能锅炉节能监察工作的开展。

本人持有这种想法的根据如下：在对在用燃煤锅炉进行热效率测试时，只要在现场测量锅炉排烟温度ex，烟气中一氧化碳的含量CO，氧含量O，冷空气温度t l.a，测定换算得到炉膛的过量空气系数α，如果锅炉运行中有蒸汽喷入炉膛，则记录喷口尺寸和蒸汽压力；然后取回煤样、炉渣和飞灰样返回到检验机构检测出煤的收到基低位发热量Q net，，煤的灰分收到基质量百分数A ar，飞灰可燃物C f.a，炉渣可燃物含量(含碳量)C sl ar等，就可以根据燃用煤的化验分析数据，按照下面所述的方法计算燃煤锅炉的热效率(误差在1.5%左右)和耗煤量，推导锅炉的运行状况。

而燃油、燃气锅炉的热效率测试就更容易进行，只需要在现场进行测量锅炉排烟温度，烟气中一氧化碳的含量、氧含量，冷空气温度，测定换算得到炉膛的过量空气系数就行了，无须采样分析。

这是因为按照常规，燃气供应单位应该向也应向使用单位提供燃气的成分(如果燃料供应单位确实无法出具燃料的成分分析资料，只好取样送到具备燃料的成分分析设备的单位进行化验)；而按相关规定，燃油锅炉用代表性0号柴油的组成质量成分是：W y 0%，A y 0.01%，C y 85.55%，H y 13.49%，O y 0.66%，N y 0.04%，S y 0.25%；低位发热量为42900kJ/kg。

燃烧氧化-非分散红外吸收法

燃烧氧化-非分散红外吸收法
燃烧氧化-非分散红外吸收法（CO-NDIR）是一种广泛应用于气体分析和检测的测量技术。

该技术适用于测量环境空气、废气排放和工业过程中的气体成分，尤其适用于高精度和高灵敏度的气体检测需求。

CO-NDIR法通过测量气体中CO的含量，实现对气体的分析和监测。

CO-NDIR法的原理是在氧化炉中将待检气体中的CO与氧发生反应，产生CO2和热能，然后使用非分散红外光谱仪测量CO2的吸收，从而获得待测气体中CO的含量。

该技术具有灵敏度高、精度高、响应速度快等优点。

另外，CO-NDIR法具有测量范围广、抗干扰能力强等特点，能够满足多种气体检测需求。

CO-NDIR法的测量过程中，需要注意以下几点。

首先，氧化炉中的温度和氧气的流量需要控制在一定范围内，以保证反应的充分和稳定。

其次，非分散红外光谱仪的光路需要保持清洁，以避免灰尘等杂质对测量结果的干扰。

另外，CO-NDIR法适用于对CO的测量，对于其他气体的测量需要使用不同的方法。

CO-NDIR法在环保、工业生产、室内空气质量检测等领域得到了广泛应用。

例如，在环保领域，CO-NDIR法被用于监测废气排放中CO的含量，以确保排放达到国家标准。

在工业领域，CO-NDIR法被用于检测制造过程中气体泄漏，以保障生产安全和环保。

在室内空气质量检测中，CO-NDIR法被用于检测室内空气中CO的含量，以保证室内空气的质量和人员健康。

总体来说，CO-NDIR法是一种可靠、高效的气体检测技术，对于环境保护、生产安全和人类健康具有重要意义。

200位置的紫外峰

200位置的紫外峰指的是在紫外光谱中，波长为200nm处的吸收峰。

紫外吸收峰的选择应该根据实验需要和样品特性来确定，应该满足以下几个条件：
1.选择合适的波长范围。

根据样品的特性和实验需要，选择合适
的波长范围进行测量。

常用的紫外吸收波长范围为200-400nm。

2.选择最大吸收峰。

在所选波长范围内，选择最大吸收峰进行测

如果样品中含有多种成分，可以通过对不同波长下的
吸收峰进行比较，来确定最合适的测量波长。

一氧化碳与氧气的收集装置

一氧化碳与氧气的收集装置英文回答：Carbon monoxide (CO) and oxygen (O2) are two important gases that can be collected using specific devices. Let's talk about the collection of carbon monoxide first.To collect carbon monoxide, one common method is to use a gas syringe. A gas syringe is a device that allows the collection and measurement of gases. It consists of a cylindrical barrel with a plunger that can move back and forth. The barrel is filled with water, and a small opening at the top allows gas to enter or exit.First, we need to generate carbon monoxide gas. This can be done by burning a carbon-based fuel, such as coal or wood, in a controlled environment with limited oxygen supply. The incomplete combustion of these fuels produces carbon monoxide gas. The gas is then directed into the gas syringe using a tube or a connecting apparatus.Once the carbon monoxide gas is in the gas syringe, we can collect it by pulling the plunger back, creating a vacuum inside the barrel. The gas will flow into the syringe to fill the vacuum. We can then measure the volume of the collected gas by reading the markings on the syringe barrel.Now let's move on to the collection of oxygen gas. Oxygen is abundant in the atmosphere, but it can also be collected and concentrated using specialized devices called oxygen concentrators.Oxygen concentrators work by separating oxygen from other gases in the air. They typically use a process called pressure swing adsorption (PSA) to achieve this. The air is drawn into the concentrator, and it passes through a series of filters and sieve beds. These beds contain a material that selectively adsorbs nitrogen, allowing oxygen to pass through.The collected oxygen is then stored in a reservoir ordelivered directly to the user through a tube or mask. Oxygen concentrators are commonly used in medical settings to provide supplemental oxygen to patients with respiratory conditions.中文回答：一氧化碳（CO）和氧气（O2）是两种重要的气体，可以使用特定的装置进行收集。

部分二氧化碳重吸收法测心输出量

部分二氧化碳重吸收法测心输出量心输出量（CO）是重要的血流动力学参数。

器测量方法分为有创和无创两大类。

前者主要有温度稀释法、燃料稀释法、直接fick发、电磁流量法等；后者主要包括超声心动图、胸部电阻抗图、脉搏图、完全二氧化碳冲吸入法等。

1980年以来，一种新的无创性CO测量方法——部分二氧化碳冲吸入法（partial CO2rebreathing cadiac output measurement）被提出。

经动物实验和临床研究证实，该法与其他方法所测CO有良好的相关性，临床应用前景较好早在1870年，Adolf Fick即提出测量人体CO的理论，认为血液经过肺时所吸收的氧量必然等于经过口鼻吸入的氧量。

如果测量出每分钟集体吸入的氧量（VO2）、动脉血和混合静脉血的氧含量差（Ca O2-Cv O2），即可计算出通过肺毛细血管的血量（pulmonary capillary blood，PCB）加上肺内分流量即为CO。

PCB=VO2 CaO2−CvO2如果测量出每分钟机体呼出的CO2量（V CO2）及混合静脉血和动脉血的CO2含量差（Cv CO2-Ca CO2），也可计算出PCB。

PCB=VCO2 CvCO2−CaCO2尽管以上两个公式为经典的fick公式，但需要放置右心导管和动脉穿刺抽血进行血气分析，具有一定的创伤性，且不能连续测定，在临床上广泛应用受限。

近20多年来，人们对CO2重吸收法进行了研究。

初期采用完全重吸入法，用一气囊链接病人口鼻，完全重吸入呼出气，并测量其中的CO2的含量，计算CO。

完全冲吸入法不但操作不便，而且CO2体内潴较明显，不适合于危重病人。

1980年，Gedeon等受限提出部分CO2重吸入技术，后由多人加以补充完善采用增加死腔量等措施，使机体在一定时间（30-50秒）内重复吸入部分CO2，并计算吸入前后的PCB。

PCB重吸入前=VCO2重吸入前CvCO2重吸入前−CaCO2重吸入前PCB重吸入后=VCO2重吸入后CvCO2重吸入后−CaCO2重吸入后假设在短暂的重吸入期内PCB、CO和静脉血CO2含量均没有发生明显的变化，以上两式可以合并为一式PCB=VCO2重吸入前−VCO2重吸入后CvCO2重吸入前−CaCO2重吸入前−(CvCO2重吸入后−CaCO2重吸入后)由于机体对CO2有很强的储蓄功能，不论从理论推测还是实验数据均表明在短暂的重吸入期内静脉血CO2含量保持相对的恒定，这样，上式可简化为式VCO2重吸入前−VCO2重吸入后CaCO2重吸入后−CaCO2重吸入前=∆VCO2∆CaCO2Ca CO2的测量相对较困难，可通过PaCO2和血红蛋白（Hb）来计算，或通过Pa CO2和CO2离解曲线来估测。
