What should you do if your kerosene flash is increasing in the column?

By flash, it is assumed you mean the amount flashed in the flash zone after entering a column. If the amount flashed is more than you desire, lower the feed temperature. If the feed is some amount of saturated liquid and vapor, you will want to increase the percentage of liquid fed to the column. This applies to a general distillation column with more flash than desired.If this is a crude oil atmospheric distillation column, and you are getting too much kerosene in a side draw, your cut point probably does not meet the required specification. In this case you will need to adjust your pumparound rates and/or increase the amount of reflux.

How can i clear flash player and java script error on you tube?

Any flash or JavaScript errors can be caused in a number of ways. Most of the time, it should be the website's fault if you receive a JavaScript or Flash Player error. Those will correct themselves over-time. But if you receive errors that you know nobody else (Or very few people) receive(s), then the problem could be on your end. Either your JavaScript, or flash player (or both), may be out of date and need to be upgraded. JavaScript can be updated by updating your browser. Flash Players can be updated by going to the Adobe website.
