Reducing Heel and Scraping - Liquid Bulk Tanker

I need some advice, or expertise rather in the liquid tanker category ...

We have a product, an industrial primer, which is very thick, that we load into a bulk liquid tank and deliver to the customer. We've noticed an influx in costs for additional heel and scraping from the wash for this one particular product. The residual heel inside the tank is hardening on the walls of the tank, causing extensive labor to clean at the wash.

I am looking and open to any suggestions that could help reduce the amount of heel being left over and/or could aid in preventing the remaining heel from hardening inside the tank before it can be rinsed or washed.

 

How long after offloading is the wash taking place? Is the product shipped hot? Might just be a cost of doing business situation.

 

It can take a day to multiple days before being washed, depends on how busy the wash is really. The product is not shipped hot, its an industrial primer with a very thick consistency.

 

Try getting it washed out as soon as possible after offloading.

 

I have hauled products similar to what you have described.

The customer would have some means of steam heat generation to hook to the tank.

If using a rear-unloading tank, make sure the front of the tank is elevated as far as possible. This is generally accomplished by means of portable ramps, or an asphalt "hump" that the rear wheels of the tractor are backed on to.

Consider using a "center drop" trailer, and if possible, run intransit heat during unloading.

 

Sounds like an IBC instead of a tankwagon.

Is there something of a solvent nature that could be added at the off-loading?

I used to pump on an aircraft hydraulic additive thru a 5 micron filter.

It took a long time to fill the 3" stainless line into the trailer, some of the most viscous product I've seen.

Deliver to the lube blending plant who pumped off half mixing it with thinned product [cutback] and loaded it into the remains in our wagon and after a ride around the facility pump it into storage.

Trailer was solvent washed with little heel while my pump spent around 3 hours circulating the pre-solve tank to get it all out.

It could be worth it to send a 5 gal pail with each IBC.

 

Can the customer accept deliveries from a center-unload trailer? And would shipping the product hot prevent the product from sticking to the walls?
