Home Forums Coking Vapor heat RE: Vapor heat



Thanks for your prompt response.
We do have coke condensate drum followed by a blowdown tower and blowdown settling drum. My idea is to introduce steam at a controlled rate thru the drum bottom section and route the same from the top (via drain between SP 4 and SP 8 – Foster Wheeler design) to the Blowdown Settling Drum which has been provided with Air Cooler. The steam condensate from the coke settling drum may be pumped to coke cutting water tank for reuse/ top up. I am not sure about the heating rate of the drum as compared to the normal vapour heating and any disadvantages as I am new to this idea. View solicited please.
