INTEGRATED PRODUCTION PROCESS OF TERT-BUTYL ETHERS OF GLYCEROL OR ISOOCTENE STREAM
The present invention relates to an integrated process that allows the production of tert-butyl ethers of glycerol, used as a high boiling point solvent (HBPS) in paint formulations (water-based) and cleaning products, or a stream of isooctenes to be used as an octane in the gasoline pool, in a simple way, just directing the flow through the areas necessary for the conversion and separation of the process and using the same equipment, aiming at gains in process yield (maximization of glycerol and isobutene conversions) and minimizing investment and operating costs. In view of this, there is a unit flexibility in producing different high added value products.

Chemical Reformer Systems And Methods
A chemical reformer system has an inlet, a digester, a series of chemical reformers, coolers and separators. The temperatures and pressures of the digester and chemical reformers may be regulated, where the pressure decreases from the first chemical reformer to the last and the temperature increases from the first chemical reformer to the last. The chemical reformer system may be utilized to convert feedstock biomass to output compounds, such as bio-oils.
Method for purifying isobutene from a C4 stream and process system therefor
A process for the purification of isobutene from a C4 stream with at least 1-butene, 2-butene, isobutane and isobutene includes isomerizing 1-butene from a stream of material which is concentrated in isobutane and isobutene obtained from the C4 stream into 2-butene, using a catalyst in an isomerization reactor; supplying a product stream from the isomerization reactor to a rectification column; and providing a stream of material which is concentrated in isobutene. A processing facility is utilized for the purification of isobutene from the C4 stream.

Method for revamping a refining section of a methanol distillation plant comprising a medium pressure (MP) column a low pressure (LP) column, wherein both said columns comprise at least one bottom boiler, a gaseous stream of distilled methanol withdrawn from the MP column is fed to at least one bottom boiler of the LP column and a liquid solution containing methanol withdrawn from the MP column is fed to the LP column, the method of revamping comprising the installation of a high pressure (HP) column; the installation of a line feeding a gaseous stream of distilled methanol from the HP column to at least one bottom boiler of the MP column and the installation of a bottom line for exporting from the HP column a liquid stream consisting essentially of water.
Process for production of essentially pure delta-9-tetrahydrocannabinol
The present invention describes a method which outlines a process for conversion of CBD to a Δ.sup.9-tetrahydrocannabinol (Δ.sup.9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the Δ.sup.9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% Δ.sup.9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce Δ.sup.9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% Δ.sup.9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the Δ.sup.9-THC using distillation and collecting an essentially pure fraction of Δ.sup.9-THC using additional distillation or enrichment form of purification. Included are methods and processes to scale the reaction from the lab to large scale manufacturing. Included are methods for adding a molecule marker to authenticate high purity Δ.sup.9-THC products. Formulations and uses for pharmaceuticals, nutraceuticals, food products, and topicals are also provided.
Process for production of graphite coke from an admixture of coal and petroleum based hydrocarbons
The present invention provides a process for production of graphite coke from an admixture of coal and petroleum-based hydrocarbons. This particularly describes a process wherein a mixture of coal tar pitch and hydrocarbon feedstock such as CLO is purified in a solvent treatment step and the purified mixed feedstock is subjected to thermal cracking to produce high quality graphite/needle coke. This process also provides a synergy in improved coke quality coke formation while using an admixture of coal tar pitch and CLO while subjected to common purification and coking steps.
Refrigeration recovery from reactor feed in a propane dehydrogenation system
A method to recover refrigeration credit from propane feed to a propane dehydrogenation reactor by fully condensing a Depropanizer overhead stream, letting the condensed stream down in pressure, and vaporizing the stream at lower pressure against process streams to recover refrigeration credit.
Process for C.SUB.5+ .hydrocarbon conversion
The invention relates to C.sub.5+ hydrocarbon conversion. More particularly, the invention relates to separating a vapor phase product and a liquid phase product from a heated mixture that includes steam and C.sub.5+ hydrocarbons, catalytically cracking the liquid phase product and steam cracking the vapor phase product.
CONTROL METHOD FOR RECTIFICATION AND PURIFICATION SYSTEM OF ELECTRONIC-GRADE CHLORINE TRIFLUORIDE
The present disclosure provides a control method for a rectification and purification system of electronic-grade chlorine trifluoride. A rectification device of electronic-grade chlorine trifluoride includes a two-stage cryogenic rectification device including a low-boiling column and a high-boiling column. An extraction agent is arranged in the two-stage cryogenic rectification device for further dissociating associated molecules of hydrogen fluoride and chlorine trifluoride to meet the requirements of electronic-grade chlorine trifluoride. The reflux ratio parameter stability of a vapor-liquid (chlorine trifluoride-hydrogen fluoride) phase equilibrium system can be effectively improved by a column plate temperature control method, thus realizing wide dynamic smooth running under various working conditions. The column plate temperature control method can achieve an effective separation of chlorine trifluoride and various impurity components by deep rectification technology, yielding electronic-grade chlorine trifluoride through purification.
