You can install the thermowell in an elbow.

Set your recycle loop for different flowrates and see how the conversion improves at each setting.

We completed a feasibility study for the production of H2S for a major fortune 500 company. They were not near a refinery. The conversion of CS2 by hydrolysis is another route.

Consider the fluidized bed heat exchanger which is a self cleaning heat exchanger. See http://rccostello.com/klaren.html If you are down once per month for cleaning this may be a possible answer to your problem.

Google the COPure Process.

Fugitive emissions are vapors not solids or liquids with vapor pressure such that the vapors are emitted from the valve stem at the process temperature. Typically they are hydrocarbons. They increase the air pollution from a given facility. Salt water that comes out of a leaking valve stem would...

Is the solvent water or hydrocarbons?

Take a look at this self cleaning heat exchanger. http://www.rccostello.com/Costello-Klaren-web.html Fill out the questionnaire and email in. They must be mounted in a vertical position and they circulate chopped wire that is the same metallurgy as the tubes. This wire scours the tubes...

Fact 1 - We have never seen the propane levels at that concentration and measured oxygen can go below 5% and this is at many locations. Fact 2 - Turn the air off and the reaction stops. If you loose cooling water the air blower should turn off automatically. No significant reactions occur even...

These guys make desalters too. http://www.certifiedway.com/edge-products

First you may be below the Minimum Oxygen of Combustion as the mass of asphalt is absorbing oxygen and it is cross linking/ reacting with the asphalt. At the start and finishing of the cycle you will most likely be in the flammable envelope. The flame arrester will plug and sometimes after...

Formz, There is no azeotrope in a methanol water system. This is a very simple binary distillation that is routinely performed in the biodiesel industry.

Thanks Guys

We provide Engineering services to startup Biomass to energy companies. In the past we worked with the fortune 500 where getting paid was never an issue. Many of these startups have received their first round of funding. How can we insure payment at the end of say a front end engineering...

We have designed numerous sulfuric battery acid dilution systems. In each case we used a teflon lined tee and then a teflon heat exchanger to remove the heat of mixing. ash9144 said it on Dec 10.

One such technolgy for removing Carbon Monoxide from a mixed gas stream is COPure.

What is your reflux ratio? How many theoretical stages do you have in your column? Have you considered increasing the reflux ratio? You must be able to get additional heat into the unit to maintain the same production rate. Also you don't want to flood the column.

I use the process simulator ChemCad from Chemstations. It also predicts hydrate formation.
