CONVERSION OF COAL WITH OXIDATIVE HYDROTERMAL DISSOLUTION (OHD) PROCESS

Why this project did not progress/complete fallowing millions dollars investment last two years?
​

Trail: Failed/Wrong doing/No results
Investment: Millions dollars investment no results
Who is doing what/When/How about OHD project
Cost: What was the cost so far and what is the plan for further expense

“Oxidative Hydrothermal Dissolution (OHD) is a novel coal conversion technology developed with support from the Illinois Clean Coal Institute.

OHD works by reaction of coal and/or biomass with small amounts of oxygen in high temperature, high pressure, and liquid water. This breaks up the coal’s structure, resulting in the generation of low molecular weight, water soluble products.

Complete conversion of the coal is readily achievable with 70-90% recovery of the original carbon as water soluble products. Most silicate minerals present in the coal pass through the process essentially unaltered.

Raw OHD product is an aqueous solution (not a colloid or suspension) consisting of a mixture of low-medium molecular weight aromatic and aliphatic acids and related derivatives that could potentially supplement or replace some petroleum–derived products as chemical feed stocks.
Raw OHD product can be pumped and refined using conventional liquid processing technology.

Since the process uses only water and oxygen, it is inherently environmentally friendly.
No exotic solvents or expensive catalysts are required. It produces little CO2, and no NOx, SOx or other toxic emissions.

Harmful elements like mercury, arsenic etc., are not released to t environment but either remains associated with their parent minerals or are retained in the product solution and can be processed and captured by conventional waste water treatment strategies”.

Where is the progress and results for such an ambition project?

Process

OHD process is adding value into poor quality coal to convert much more valuable product. It is a proven technology and able to commence commercially viable processing plant.

Oxidative Hydrothermal Dissolution (OHD) is a different than its predecessor. It is one of the efficient processing systems, which based on scientific research data and commercially viability.

The process technology has wide range of applications. The number of product can be produce with this technology endless.

100% environmentally friendly; no harm to air, soli and human health.

Extremely low operational cost
Very low energy cost,
No waste
No harmful chemical use

Row material – Feed is vilely and cheaply available around the World (Brown Coal one of can be cheapest material to process)
Process reaction and equation is 100% in balances

The OHD product is an aqueous solution consisting of a mixture of low- to – medium molecular weight aromatic and aliphatic acids and related derivatives products as chemical feed

No exotic catalysts or additional solvents or reagents are required.

GPP has commercial and technological right/Licence for well-established pilot-scale system with capacity of 10 to 20 kg/hr in USA.

GPP does not need another demonstration/development unit. This technology proven technology and does not need to lab scale unit.

Instead GPP should have a small scale production unit. This unit can be manufacture much cost effective way in Australasia.

The system was designed to control system & process variables, including pressure, temperature, flow rate, concentration of product system with water recycle over specified range of operation conditions.

A control loop allowing the operator to control the extent of dewatering almost 99% by removal of water system. The recovered steam can be re-condensed with heat recovery and water recycle.

If this process so cleaver and readily available for market why we are waiting many years to come and construct a small size a toy PDU?

Technology

OHD works with water, pressure, temperature and natural and synthetic organic materials, in this case “Brown Coal”. With Oxygen feed for temperature elevation.

The solid feed can coal, biomass or any other solid organic materials
The entire process requires only water, oxygen and right set of conditions

OHD produce very little CO2 which can be recycle and contain, no gaseous nitrogen or sulphur oxide.

The OHD processing unit is consistent of slurry mixer/mill, heaters, oxidant recovery, reactor, flash concentrator with steam recovery discharge and clarifier

OHD process can be continues or batch process, controlled by interface control system.

The control system will be controlling valve operation, oxygen feed, raw materials feed, pressure and temperature control sensors with gauges

OHD uses oxidative bond scission to break these macromolecular structures, using subcritical liquid water as reaction medium (as solvent) and dissolved O2 as the oxidizing agent.

OHD is able to achieve complete conversion greater than 90% carbon recovery.

Technology and process available, all licences obtain/purchased and tomato trial keep going last two years without results (just they find lack of Calcium with sick tomato. Ref: recent picture of OHD Tomato in one of GPP announcement)?

Market

OHD process is capable to utilise for multiple application; such as coal, biomass.
Final product will be excellent for users, environment and investors.
Product can be transported easily around the World.
GPP can offer free trial for end users

GPP Management

GPP management is currently use very expensive and most of the time using very expensive unnecessary consultant/university/academics. OHD projects should be centralised and manage efficiently has very capable technical team and management.

A project execution “Road Map” must be prepared.

GPP Management spent our millions dollars for what? No grant, no partner, no trial. Unfortunately none of these achieved so far.

Material and Energy Balance

Material and energy balances are very important in an industry. Material balances are fundamental to the control of processing, particularly in the control of yields of the products.

The material balances are determined in the exploratory stages of a new process, improved during pilot plant experiments when the process is being planned and tested, checked out when the plant is commissioned and then refined and maintained as a control instrument as production continues.

When any changes occur in this process, the material balances need to be determined again. GPP Management did not inform shareholders regarding materials and energy balance of OHD projects so far.

Material quantities, as they pass through processing operations, can be described by material balances. Such balances are statements on the conservation of mass.

Similarly, energy quantities can be described by energy balances, which are statements on the conservation of energy. If there is no accumulation, what goes into a process must come out.

Energy balances are used in the examination of the various stages of a process, over the whole process and even extending over the total production system from the raw material to the finished product.

The availability of advanced PDU has meant that very complex mass and energy balances can be set up and calculated quite readily and therefore used in everyday process management to maximize product yields and minimise costs. If all has been done then where are the results?

VICTORIAN BROWN COAL CHEMICAL COMPOSITION

The following brown coal chemical composition viability as feed need to be further investigated. Is anybody from the GPP management look at this!!! If they where is the information?
