Also known as: Toluene Insoluble Organic Matter (TIOM's), Petcoke, Smarties & Diamond Black.
Residual Petcoke/TIOM's have proven to be one of the most difficult by-products to remove from piping, valves, pumps, heat exchangers, vessels & treaters at refineries and upgraders everywhere.
Petcoke/TIOM’s are commonly characterized as asphaltenes since they appear as a black deposit or sludge in tanks, exchangers, reboilers and numerous other systems. What is unique about this material is that it is not soluble in toluene or almost any conventional solvent.
Certain solid fractions are associated with significant amounts of toluene insoluble organic matter (TIOM), physically or chemically adsorbed onto particle surfaces. These fractions are generically described as ‘organic rich solids’ (ORS).
Two types of ORS have received particular attention.
The first is a coarser fraction, usually less than 44 μm but also occurring as particles greater than 100 μm in diameter. This material typically occurs as aggregates of smaller particles bound together by humic matter and precipitated minerals.
The second important fraction comprises very thin, ultra-fine clay particles with a major dimension of <0.3 μm. These ultra-fine clays, with a surface coating of organic matter, remain with bitumen during the separation process. In bitumen upgrading, these solids may be entrained with volatile overheads and cause problems in downstream operations.
This insidious problem can cost millions of dollars/year to remove from operating systems. The process of removing these residuals removes valuable equipment from operations while they are being cleaned and with that comes a corresponding blow to revenue.
Added to this already major hit to the bottom line are those ancillary costs associated with damage to equipment through the mechanical or caustic cleaning process, the costs of extra precautions needed to safeguard employees and of the plant itself from toxic chemicals used in the process as well as those from discharge, environmental, trucking and handling fees.
RAW Biochem's Petcoke Liquifier is the antidote to conventional cleaning methods.

Soft & Malleable
RAW's Petcoke Liquifier is a clean-in-place (CIP) bio-based chemical which liquifies petcoke. This liquification process:
Eliminates the need to fully cool piping and exchangers before cleaning
Eliminates the need to remove LEL's or H2S from systems prior to cleaning treatment
Eliminates the need to pull bundles from exchangers
Eliminates the need for pigs & caustics. This is a clean-in-place process with no disassembly of the equipment needed when removing residue.
Eliminates the need for new seals and gaskets in exchangers
Eliminates the need to hydro-test before restarting as all equipment has remained intact during cleaning.
The bottom line benefits include:
The CIP process reduces operational downtime to a single shift and increases operational revenue with quicker turnarounds.
Petcoke Liquifier extends equipment duty cycles. Petcoke Liquifier is a bio-based ZERO hazard chemical which will not harm ferrous or non-ferrous metals, gaskets or seals
Petcoke Liquifier is non-reactive and will not off-gas or create VOC's.
it's non-flammable status minimizes employee liabilities
A non-reaction to hydrocarbons or chemicals. This means there are no liabilities and no additional chemical treatments are needed to optimize profitability.
Reduced concerns of adhering to spill protocols. The CIPO program minimizes extraneous spills and reduces time on site for remediation.

Testimonial Email from PDVSA Petropiar: 12/05/2014 (Google Translated copy)
" There was a chemical cleaning to the exchanger 10-E-012 with the product Petcoke Liquifier for muddy water exchangers PP provided by Suplitrol, which was effective.
Below is the behavior that has had the 10-E-012 after its chemical cleaning (reviewed in annex mail). The same according to trend, see Figure No 1., present low temperatures in the effluents compared with those observed in dates before cleaning (172 F before versus 126 F current).
There was a simulation Pro II team to verify heat transfer before and after cleaning, and it indicates that the heat transfer efficiency improvement was substantial, whereupon INTEVP/PetroPiar endorses this procedure for future cleanups"
