How can trace amounts of liquid be removed from gas to achieve complete purification?

2021-03-09View Original

Thread Content

So far, the coalescer is capable of reducing levels to 0.01 ppm, achieving complete purification of the gas! The removal of trace liquids from gases generally includes the purification of hydrogen (liquid light hydrocarbons in circulating hydrogen), the purification of instrument air, and the removal of amine solution after amine washing of dry gas/low-boiling-point gas! Removing trace amounts of liquid from gas: the liquid content before removal is crucial, as it directly determines the number of filter elements required. With fewer filter elements, the liquid definitely can’t be cleaned thoroughly ; More filter elements increase costs. Only professional design manufacturers can select the appropriate model based on the liquid content! So far, through calculations, if the amine in the gas after amine washing is reduced to 0.01 ppm, the benefits generated by the recovery of amine alone each year are sufficient to cover the cost of the equipment, not to mention the damage costs caused by the amine present in the gas to downstream pipelines, compressors, and other devices. There are numerous domestic coalescer manufacturers, and various unrealistic promises make it difficult for customers to determine which equipment is of good quality. For a good piece of equipment, the design and selection are not that simple; it requires taking multiple factors into account and performing a series of complex calculations to determine the appropriate choice. So, the problem of gas carrying liquid will no longer be an issue!

The operating cost of drying is relatively low due to the frequent replacement of desiccants or the regeneration of these desiccants, which takes place on a short cycle basis. The replacement cycle for the coalescer filter elements is usually measured in years. Of course, for cases where the liquid content is extremely low (a few to dozens of ppm), using a drying method may result in lower costs.

It’s a good thing; it depends on the quality of the coalescer

Yes, the key lies in whether there are good products available, including proper design choices and high-quality filter elements.

After two layers of demisters in the upstream stage, activated carbon adsorption is used in the downstream stage; the activated carbon is regenerated using steam during periodic shutdowns

It’s too troublesome; the investment cost isn’t necessarily low
