Syngas Generator Safety Reliability
Jun 13, 2017

Syngas Generator in the use of the process encountered two common problems, one is difficult to guarantee the reliability, the second is the safety problems. Its reliability is difficult to ensure that the performance of some of the generators in the purity is not enough, nitrogen and hydrogen in the water content is high and also with a certain degree of corrosion, if the operation will have a return phenomenon occurs. The above situation will cause the chromatograph is not easy to stabilize and the column efficiency of the column is reduced, serious can make the gas path and the column scrapped, and even causes the chromatograph all scrapped. Followed by the use of the process of security problems, some of the gas generator compressor in the course of the use of overheating, gas into the oil, leakage and other phenomena, not only damage to the chromatograph, serious will endanger the operator The safety of life.

Because the chromatograph uses high purity nitrogen or high purity hydrogen as the carrier gas, in order to deal with the above problems, we from the hydrogen generator, nitrogen generator and compressor safety and reliability of the three aspects of a few lessons for your reference. Air as auxiliary gas its purity is not high, after dehydration degreasing can basically meet the chromatographic analysis requirements,Syngas Generator so this article is no longer detailed analysis.

First of all, the hydrogen generator is mainly composed of electrolysis system, pressure control system, purification system and display system. Electrolysis using the current membrane separation technology, by the infrared photoelectric feedback device and switching power supply composed of pressure control system, so that the amount of hydrogen generated according to the needs of the output automatically adjust to maintain the output flow and pressure stability. The main problems with the use of hydrogen produced by this principle are:

1. Hydrogen generator with KOH aqueous solution produces high moisture content and is corrosive in hydrogen. It is easy to cause instability of chromatograph debugging. Once the hydrogen gas is used for a long time, the carrier gas will inevitably decrease.

2. The use of the principle of hydrogen generated if used for a long time, will cause serious back to the liquid phenomenon. In order to prevent back to the liquid, manufacturers have designed a variety of devices to try to solve this problem, but can not solve the fundamental problem. After all, it is necessary to add liquid, once the anti-back to the device failure will cause the gas and column scrapped, serious or even lead to all the gas scrapped.

3. Most of the purity of the gas has not been tested,Syngas Generator although it can be judged by the baseline and column life of its purity, the result is to the column caused unnecessary losses.

So the hydrogen as auxiliary gas is also OK, so that the carrier gas purity is not enough. In the choice of hydrogen generator priority given to the quality of the manufacturer, you can also install the online purity detection device to ensure the purity of the gas.

Secondly, the nitrogen generator can be well applied to gas chromatography analysis experiments, and the principle of the generator has a great relationship. The working principle of the nitrogen generator is roughly divided into three types:

1. The combination of electrochemical separation and physical adsorption

2. Separation by hollow fiber membrane

3. Separation by a new synthetic molecular sieve using gas chromatography

The use of this principle produces a lot of nitrogen problems. The main questions are:

1. The nitrogen generator of the KOH aqueous solution produces high moisture content and is corrosive in nitrogen.

2. There is back to the liquid phenomenon.

3. Nitrogen purity is low, the thermal conductivity of the detector thermal conductivity detector will cause oxidation, a long time the thermal conductivity detector sensitivity.
