Krod Energy Resources Limited uses three methods of tank cleaning services; Manual method, Downhole nozzle application method and Sludge Master Solvent Extraction method.
The following information is based on Krod tank cleaning practices for downhole nozzle application method:
Krod Energy Resources Limited uses the latest equipment in its tank cleaning operations. The Sludge Master Jet Nozzles is the latest technology for cleaning Crude Oil and other tanks containing heavy sludge. The Sludge Master Jet Nozzle can be mounted on tanks where the sludge levels are above the man ways using an adapter flange and cold tap and the customer wants to recover the oil. This method eliminates the need to hot tap. Generally , crude oil is 90% recoverable as a usable oil .The Sludge Master /Tank sweep jet Nozzles are designed to circulate, suspend and fluidize the sludge using the existing oil in the tank, although a better recovery rate can be achieve using a solvent that’s made in the refinery such a light cycle oil or unfinished diesel.
SludgeMaster has a flow rate of 660m3/hour @ 10bar.One SludgeMaster has the capacity to clean up to a 31m diameter tank. For 90m diameter tanks at least 3 SludgeMaster are required .They can be mounted on the tank’s existing man ways , regardless of the sludge/oil level, without having to hot tap the tank. Tanks with 1meter or more of sludge can be circulated, fluidized, and pumped out in as little as 3-5 days depending on the sludge profile and the customer’s needs.
Selective Solvent Extraction Method. This method liquefies the organic compounds in the sludge without using expensive chemicals, returning valuable hydrocarbons to the customer and significantly reducing waste disposal while cutting the cleaning time by almost 2/3.
Procedure:
What we can do for your company:
Cleaning crude oil and other heavy oil tanks have a history of being expensive, time consuming, and generate solid waste and it is a science that most companies have yet to master. We can offer your company the following benefits from using our system:
Solvent Extraction is:
We also:
Finally we can assure you that the dollars you will save from our oil recovery will be much more than what it cost to do the work. For example, you are going to recover around 90% of the sludge as a useable oil. For instance, if you recover 10,000 barrels of oil, multiply that by the current cost of a barrel of oil. You have also eliminated 90% of what it would cost for disposing of the sludge.
Krod Energy Resources Limited, employs various technological methods in our Industrial cleaning services, we use Ultra/High Pressure Jetting systems (UHPJ &HPJS), Vacuums Transfer System (VTS), Pipe Cleaning Technology and Non-Man Entry Automated Tank Cleaning Systems (NEATS).
Surface Cleaning
We implement safe work systems and clean surfaces using UHPJ or HPJS depending on surface/material strength and quality. Water is used in a wide range of our cleaning applications however we do apply chemical in peculiar situations like presence of recalcitrant deposits. We also undertake exterior cleaning at heights and delicate surface cleaning.
FPSOs, Tanks, and Vessel Desludging and Cleaning
We provide fast, efficient and safe desludging and cleaning services for FPSO using automated cleaning system with High Pressure Jetting and Vacuum Transfer System capable of water jetting and cleaning of the interior surfaces, and evacuating sludge from a depth of over 50meters in FPSO.
Non-man Entry Automated Tank Cleaning System (NEATS)
TIP cleans crude, chemical and product storage with minimal risk to facility and humans. This System limits confined space safety concerns, risks to facility and environment and at the same time ensuring timely delivery. The Vacuum transfer is accompanied by Sludge loading Carousel (SX800) capable of loading Waste Skips directly from 50metres depth.
Pipelines and Sewers Cleaning
We have a pipe cleaning technology capable of removing difficult deposits (including pyrophoric sludge, spent Amine sludge, mud cakes, etc) without confined space risk concerns from pipes, in a very efficient and safe manner. These blockages might have resulted from deposits accumulated by transporting crude oil or gases also Sewer lines (including underground drainages) get clogged and blocked over time as a result of various sizes of debris conveyed through them. This has caused serious flooding problems in most cities.
Heat Exchangers Tube and Fins Cleaning
The major causes of Heat exchanger inefficiency are scales and deposit. Our cleaning equipment allows for a quick and efficient cleaning of Shell, and Tube heat exchangers as well as plate, Air-cool Fins, and frame heat exchangers, eliminating sediments in no time. We offer cleaning technology that can clean either straight or spiral enhanced chiller tubes. They are ideal for cleaning tubes/pipes of 1/4” and above internal diameters in chillers, condensers evaporators and heat exchangers.
