Maoming Petrochemical optimizes tank area traps to achieve steam saving goals

China Petrochemical News Network reported in June 2021, the Maoming Petrochemical Refining Division's storage and transportation workshop optimized and rectified the tank area heating line traps, reducing the direct steam loss of the heating line, saving 0.
5 tons of steam per day, and reducing the use of steam by RMB 1,099 per day.
The annual steam cost can be about 400,000 yuan
.

The steam trap is responsible for draining the moisture in the heating pipeline.
A high-efficiency trap can drain the moisture in the pipeline in time to ensure the heating effect of the pipeline.
If the efficiency of the trap is not high, the steam will be drained while draining.
Drainage leads to wasted steam.
Second, the poor drainage effect causes water accumulation in the pipeline, resulting in poor heating effect
.

The asphalt tank area of ​​the storage and transportation workshop stores heavy feedstock oil.
The heavy feedstock oil needs to be heated by a steam heating line to prevent the oil from solidifying and ensure the smooth flow of the oil in the pipeline
.

In view of the large amount of heat tracing steam loss in the tank area, the workshop equipment professional conducted several on-site surveys and verifications in June.
After negotiating with the relevant departments and the feasible plan, it was decided to add 14 traps and 28 additional steam traps on the original auxiliary line of the steam tracing pipe.
The heat pipes are separated and independently used with steam traps, and the heating efficiency of the heat tracing pipeline is greatly increased after a separate steam trap.
The process production can be met without the need to open the steam sub-line, and the loss of direct steam discharge is reduced
