alternative natural rubber production pilot plant process design

The client, in joint cooperation with a tire industry consortium, was seeking to develop a process to produce an alternate source of natural rubber from the roots of the Russian dandelion or Taraxacum kok-saghyz (TKS) plant. There are two competing processes to obtain natural rubber and latex from the TKS roots.  Natural rubber and latex are two different forms of rubber with different properties, different uses, and different markets.  Natural rubber is the more important product for tire companies, and is meant to compete directly with natural rubber obtained from the rubber tree plant.  Previous work on a process to obtain natural rubber from the TKS root had been done in the 1940s and some additional recent laboratory work had been conducted.  Process Engineering Associates, LLC (PROCESS) was contracted to lead the process design effort of a new pilot plant using modern technology.
Based on the initial phase of the project, it was determined that custom equipment would be needed.  Read more here to learn how PROCESS developed the design package.

sludge pretreatment system alternatives; technical and economic evaluation

Process Engineering Associates, LLC (PROCESS) was contracted to perform a detailed technical and economic evaluation of the critical operations associated with a sludge pretreatment system design to prepare a biological sludge stream for continuous processing through the thermal treatment system.  Technical and economic evaluations were performed for alternatives associated with the following operations:

  • Sludge Dewatering
  • Sludge Drying
  • Sludge dryer offgas organic removal

How many alternatives can you think of for sludge dewatering, drying and offgas removal?  PROCESS evaluated 7 dewatering applications, 14 drying applications and 9 offgas removal alternatives.  Follow the link here to learn about the alternatives evaluated.

Technical Discussion – Minimizing Process Risks – Maximizing confidence in Your Capital Investments


When executing capital projects, small or large, the ultimate objective is to produce something that works as planned, at the lowest possible cost, with the most commercially desirable attributes, and meet all applicable laws and standards.  In other words, maximize the return on investment while minimizing health and safety concerns.  To do this, it is extremely important that process risks are identified and managed in the early phases of a project to ensure that the design is robust and that project goals can be met.


Process Risks – Definition / Impact
What is a “process design risk”?  This is a risk associated with the process design that would result in the potential for a new or modified process to fail to meet the overall project objectives.   Whether the objective is to produce a new material, scale up an existing process, optimize an existing process to create a better product, or simply produce a saleable product from an existing byproduct or waste stream, the decision to invest in the project assumes that a specified amount of capital investment will result in an expected amount of monetary return.   Process risks, if not identified and managed early in the project, can easily jeopardize its success and result in significant disappointment for the project owner, investors, and even product clients. Some specific examples of process risk areas: keep reading

take a pause for safety – Process offers pha leader training course

PROCESS ENGINEERING ASSOCIATES, LLC is pleased to publicly offer a 3½-day PHA training course.

The purpose of the 3½ -day training course is to assist personnel at chemical plants, petrochemical plants, petroleum refineries, and manufacturing plants in becoming proficient in leading and documenting process hazard analyses (PHAs) by becoming familiar with various qualitative hazard review techniques and industry best practices for conducting and documenting PHAs.

Who should attend:  Managers and engineers responsible for conducting PHAs at chemical plants, petrochemical plants, petroleum refineries, and manufacturing plants.

Detailed instruction of the following hazard review methodologies will be included in the course:

  • Hazard and Operability (HAZOP)
  • What-If
  • Checklists
  • Failure Modes Effects Analysis (FMEA)

An introduction to Layer of Protection Analysis (LOPA) will also be included.
