oil refinery

Refineries

The refineries are not a part of the production of oil and gas. Here the crude oil is converted into high value products, such as fuel, kerosene, naphtha, lubricant oil, LPG, and also asphalt and petroleum coke.
By heating the crude, different components of the crude are extracted at specific temperatures. Most of the refineries are specialized to do only some of the end products.
In the different process steps the heating is always the essential part. The heating is done by steam or by so called reboiler.
By heating crude or oil in heat exchangers a lot of fouling takes place. Fouling in this case means that part of the content of the crude is sticking to the inner surfaces of the heat exchangers. This leads to blocking of the flow and as well to less heat transfer from one side of the heat exchanger to the other side.
Regular cleaning of the heat exchangers has to be done, during planned shut downs every few years, all the equipment is dismantled and cleaned mechanically or by the use of chemicals.

Merus improves the heat transfer and stabilize the fouling

The reducing of scale and fouling on the water cooling side of the heat exchanger, Merus has proofed a lot of time its ability to stop the same.
On the Hydro Carbon side of the heat exchnager it has been show as well that Merus is able to at least stabilize the heat transfer in some cases in already fouled heat exchanger on the hydro carbon side the calculated heat transfer Q has slightly improved again.

Merus is able to reduce cost of heating/cooling

By having better heat transfer the benefits are obvious. Processes are running stable if cooling or heating is as its designed value. A better heat transfer direct saves fuel in the reboiler, where the crude is heated. With fuel saved, less carbon is emitted. Less fouling in the equipment gives less stress to pumps and machines.   
Until today there are no long term experiences available. Long term means over periods of 2 shutdowns or 6 to 10 years. Experience over 6 to 12 month give very positive indications.
