Standard Operating Practices/Procedures for Hydrocarbon Draining is Draining the Hydrocarbon in Close Drains.
Is there any Mobile/Portable Facilities/Skids available for doing the Hydrocarbon Draining and Collecting?

Portable “frac tanks” have been used when draining large quantities from equipment, such as during equipment draining and cleaning in preparation for turnaround. Specialty vendors can provide tanks, hoses, pumps, etc.

The question doesn't mention the quantities so assumed as 100 % HC and in quantities exceeding few KGs and from reactor /vessel/HE inventory
As a standard practice followed in the industry. there are three types of drainage systems available
Storm or rainwater systems, OWS or oily water Systems and process waste systems
The rainwater system collects only clean storm and only occasional or incidental spillage from truck vehicles etc
The OWs system collects Pump/compressor drips, equipment rinse and occasional spillage in the equipment area.
The process waste ( viz Spent caustics Stripped sour water, Desalter wastewater, etc ) is collected separately through a separate network of closed piping and sent directly to the Waste Treatment area for selective treatment
There is no provision nor a standard practice to drain hydrocarbons in these systems and can lead to catastrophic failures from environmental and safety perspective
If needed then a special system has to be designed, with safety and environmental due diligence, to drain the hydrocarbons from where the HC can be recycled to the suitable back end.As far using vehicles or trucks the safety rules will not allow movement of such vehicles in the process areas
